Product Overview and Specifications

Product Notes

The Transmitters and Receiver are designed for transmission of an HDMI signal over twisted pair cable (or a DVI signal via a DVI-to-HDMI cable adapter) up to 328 feet (100 m). Functionality is briefly described below.

DX-TX – The DX-TX receives an HDMI signal or analog video signal (composite, Y/C, Y/Pb/Pr, RGB, RGBS, or RGBHV) and an audio sig nal fro m a source device. The audio can b e either digital a udio embedded wi th the HDMI signal, di gital audio over S/PDIF, or analog stereo audio.

Either analog or digital video is transmitted out of the DXLink output. The active video selection is made using one of two methods:

1) Aut omatic, which se lects digital video as the prio rity video input or analog video when no dig ital video is present. 2) Active ICSP command video input selection from a bound NetLinx Central Controller.

Both the video and audio are transported over twisted pair cable to an Enova DGX Digital Media Switcher, an applicable Enova DVX Solution (to a DX-RX), or directly to a DX-RX.

The 232 port (RS-232) on the DX-TX supports bidirectional serial data via the twisted pair cable to/from the 232 port on a DX-RX. The DX-TX also has IR ports.

HDMI TX – The HDMI TX receives an HDMI signal and an audio signal from a source device. The audio can be either digital audio emb edded with th e HDMI, digital audio over S/PDI F, or analo g stereo au dio. Bo th the video an d audio are transported over twisted pair cable to an Enova DGX Digital Media Switcher, an applicable Enova DVX Solution (to an DX-RX), or directly to a DX-RX. The 232 port (RS-232) on the HDMI TX supports bidirectional serial data via the twisted pair cable to/from the 232 port on a DX-RX. The HDMI TX also has IR ports.

Wallplate TX and Decor Wallplate TX – These wallplates receive an HDMI signal or analog video signal (composite, Y/C, Y/Pb/Pr, RGB , RGBS, or RGB HV) and an audio signal f rom a sourc e dev ice. The audio can be eit her digital au dio embedded with the HD MI signal or analog stereo audio.

Either analog or digital video is transmitted out of the DXLink output. The active video selection is made using one of two methods:

Both the video and audio are transported over twisted pair cable to an Enova DGX Digital Media Switcher, an applicable Enova DVX Solution, or directly to an DX-RX. Direct connection requires either PDXL-2 (FG1090-170) or PS-POE-AT-TC (FG423-84).

Product Overview and Specifications

Hardware Reference Manual – DXLink™ Twisted Pair Transmitters/Receiver

DX-RX – The DX-RX receives an HDMI signal with embedded audio over twisted pair cable from a DXLink compatible device (or from a DXLink Transmitter) and sends the signal on to the destination. Audio received on the DX-RX can also be output on the Stereo Audio Out port if it originated as a 2 channel audio signal. The 232 port (RS-232) on the DX-RX supports bidirectional serial data via the twisted pair cable to/from the 232 port on the DX-TX or HDMI TX. The DX-RX features SmartScale® Technology (integrated EDID output scaling) to ensure an appropriate ou tput resolu tio n, plus it supports a Manual (override) option for setting up custom resolutions and a Bypass option. The DX-RX also has IR ports.

NOTE: If a DVI-D signal is used (via a DVI-to-HDMI cable adapter), the advanced audio support from HDMI will not be available.

NOTE: These DXLink products support several different modes which are available for system setup and use. Brief explanations of the

modes are provided in the section “Quick Reference Tables for Modes” on page 20 along with page references to complete information.

DX-TX and HDMI TX

The USB-B port on the rear of the DX-TX and HDMI TX can be connected to a PC to support a USB device. This port is considered the Host port, which is used in conjunction with the USB-A port on the rear of the DX-RX. As the Host port, it is connected to a PC and passes through informatio n via the DXLink connection to the DX-RX. A USB (mini-B) Host port is also available on the Wallplate TX and a USB (mini-AB) Host port is available on the Decor Wallplate TX.

DX-RX

The USB-A port on the rear of the DX-RX supports passthrough information from the USB Host port on the Transmitter to an HID (Human Interface Device), which is most commonly a keyboard or mouse.

HID Devices and Windows 8

Windows 8 will not wake up from a DXLink connected keyboard or mouse unless the properties for the HID device are set to allow the device to wake the computer. (No te that even a hot plug of the USB cable will not restore connectivity.)

To set Windows 8 to work with DXLink modules and HID devices:

1. On the PC, go to Start > Control Panel > Device Manager and expand “Keyboards.”

2. Right-click the HID Keyboard Device and select Properties. The HID Keyboard Device Properties dialog box opens.

5. Repeat steps for HID mouse (in the Device Manager dialog box, expand “Mice”).

HID Devices

A list is available of HID devices which have been tested and found to be working well with the latest f irmware (see “DXLink - HID supported Devices” on the DXLink Receiver’s product page at www.amx.com

USB LED

The USB LED on the front of a Transmitter or Receiver Module monitors the USB port on the rear of the unit. The USB LED illu minates (yellow) when a USB device is detected (th e po rt default is “enabled ”).

To disable the port on the Transmitter, either disconnect the cable or send the following SEND_COMMAND: USB_HID_SERVICE- DISABLE. The enable/disable co mmand pers ists through power cycling. To enable the port, send: USB_HID_SERVICE-ENABLE. The USB ports support a limited number of SEND_COMMANDs, see page 77.

HDCP Compliance

If the connected downstream sink is not HDCP compliant, then the HDMI output on the Receiver will no t send the signal. This does not affect additional displays the source may be routed to, i.e., HDCP compliant displays will still show content from the source device even when the source device is also routed to non-compliant displays. Non-compliant devices can be easily identified because they display a dark red image or an orange image to indicate the authentication process failed.

IR Control on DX-TX, HDMI TX, and DX-RX (Optional)

The following two items are required for IR control. In addition, a compatible remo te control unit can be used with the system. (The two items listed are not included with the modules.)

IR03 – External IR Receiver Module (FG-IR03). The IR03 can be connected to the IR RX port on the DX-TX or HDMI TX or to

the IR RX port on the DX-RX, allowing IR signals to be received from a compatible IR remote control. The IR03 allows the DX-TX or HDMI TX to be placed behind the display device if desired.

CC-NIRC – NetLinx IR Emitter Cable (FG10-000-11). The CC-NIRC can be connected to the IR TX port on the Transmitter

or to the IR TX port on the DX-RX. This allows IR signals to be sent to the source device from the DX-TX or HDMI TX or to the display device from the Receiver.

Hardware Reference Manual – DXLink Twisted Pair™ Transmitters/Receiver

Installation and Setup

Site Recommendations

When placing the DXLink Transmitters and Receivers in an installation, follow the recommendations and precautions in this section to reduce potential setup and operation hazards.

Environment

□ Choose a clean, dust free, (preferably) air-conditioned location. □ Avoid areas with direct sunlight, heat sources, or high levels of EMI (Electromagnetic Interference).

DX-TX, HDMI TX and DX-RX Accessibility

Make sure the front of each module is accessible, so that you can monitor the LED indicators. Leaving adequate clearance at the rear will also allow for easier cabling and service.

Power

The power source’s electrical outlet should be installed near the module, easily accessible, and properly grounded. Power should come from a building branch circuit. To avoid an overload, note the power consumption rating of all the equipment connected to the circuit breaker before applying power.

Ge n e r a l H a z a r d P r e c a u t i o n s

These recommendations address potential hazards that are common to all installations.

Elevated Operating Temperature

The maximum rated ambient temperature is 104° F (40° C) for DXLink Transmitters and Receivers. All equipment should be installed in an environment compatible with the manufacturer’s maximum rated ambient temperature. In a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than the ambient room temperature.

CAUTION:

clearance recommendation below for adequate airflow.

Airflow Restriction

The modules are designed to adequately dissipate the heat they produce under normal operating conditions; however, this design is defeated when high heat producing equipment is placed directly above or below the modules.

CAUTION:

recommend allowing plenty of clearance above the vent holes on top of the modules. Do not place anything directly on top of the modules that would restrict airflow through the vent holes on top.

Reliable Earthing (Grounding)

Reliable earthing of rack-mounted equipment should be maintained. If no t using a direct connection to the branch circuit (e.g., plugging into a power strip), pay particular attention to supply connections (not applicable when power is supplied from an Enova DGX Digital Media Switcher or Enova DVX Solution via a DXLink line). When using DXLink Power from a switcher, we recommend wiring a technical ground for the ungrounded sources/destinations with respect to the DXLink Transmitters/Receivers and switcher (see page 37).

Unpacking Tips

□ Before fully unpacking the Transmitters and Receivers, inspect the shipping box(es) for any signs of damage. If a box is □ Once unpacking is complete, closely check the physical condition o f the units.

□ Collect all documentation.

NOTE: Please save the original shipping container and packing materials. AMX is not responsible for damage caused by insufficient packing during return shipment to the factory. Shipping boxes are available; for details, contact your AMX representative.

To protect the equipment from overheating, do not operate in an area that exceeds 104° F (40° C) and follow the

To prevent overheating, avoid placing high heat producing equipment directly above or below the modules. We

partially crushed or any sides have been broken open, notify the shipping agency immediately and contact your AMX representative (see the warranty at www.amx.com

Installation and Setup

Setup Information

IMPORTANT: The setup information in this manual applies to TXs and RXs in an Enova DGX 8/16/32/64 system or in an Enova DGX

100 Series system with the auto-setup feature disabled. When the auto-setup feature for an Enova DGX 100 Series Switcher is enabled (the default), any modules or wallplates are automatically discovered and connected to the switcher using a private network hosted by the integrated Master (for complete information, see the “Hardware Reference Manual – Enova DGX 100 Series Digital Media Switchers”). In an Enova DGX 8/16/32/64 system, each module or wallplate bound to the system with traditional NetLinx binding (see page 52) acquires its own IP address from the public network (for network configuration, see page 52).

Setup Requirements

A PC with NetLinx Studio v4.0 or later installed.

An understanding of which DXLink Mode the system will be used in (see below and page 31).

An understanding of the DIP switch settings (see page 36).

When used with an Enova DGX Digital Media Switcher the system’s power requirements must be determined (see page 31).

When used with an Enova DVX Solution – The SEND_COMMANDs for enabling network activity (Ethernet traffic) over the

DXLink line must be used (see page 81).

IMPORTANT: We recommend that DXLink equipment be installed by a technician with knowledge of networks and experience with NetLinx Studio and its Telnet interface. NetLinx experience should include changing device addresses, binding devices, updating firmware, etc.

The remainder of the “Setup Information” section covers information for system setup, power budget planning, network loop concerns, binding to an integrated Master, DIP switch settings, mounting options, chassis grounding, cable requirements and recommendations (including RJ-45 pinouts and LED behavior), and audio type precedence.

The specific installation’s requirements dictate the system setup, which generally takes one of the following three forms.

Endpoint Mode (Switcher) – One or more Transmitters and/or Receivers are connected to a switcher* containing a Master

(see below).

Endpoint Mode (Standalone) – A standalone DXLink TX/RX pair are connected directly to each other but, in addition, either

the TX or RX is connected to a NetLinx Central Controller via a LAN or directly to the Controller (see page 30).

Extender Mode (Standalone) – A standalone DXLink TX/RX pair are connected directly to each other as a simple extender

solution (see page 31).

* The switcher can be either an Enova DGX Switcher or an applicable Enova DVX Solution (see “Product Compatibility Tables” on page 8).

Endpoint Mode (Switcher): Example of Typical System Setup

The primary function of the Transmitters and Receivers is to work with compatible DXLink equipment as an endpoint solution for transmission of HDMI over twisted pair cable (or DVI-D signals with the use of a DVI-to-HDMI cable adapter, or analog video signals through a DX-TX, Wallplate TX, or Decor Wallplate TX).

The Transmitter rece ives an HDMI signal and a n audio sig nal from a source device. The audio can b e either digit al audio embedded with the HDMI signal, digital audio over S/PDIF (S/PDIF is not available on the Wallplate TX or Decor Wallplate TX), or analog stereo audio. Both the video and embedded audio are transmitted over twisted pair cable to the RJ-45 connector on the DXLink Input Board. The HDMI signal is then routed through any (or all) of the connectors on one or more output boards.

When the HDMI signal is routed through a DXLink Output connector to a Receiver, the Receiver sends the HDMI signal with emb edded audio on to the destinatio n device. The audio can also be output on the Receiver ’s stereo audio port.

In systems where DXLink Transmitters and Receivers are used in conjunction with a switcher (e.g., Enova DGX 16), the cable runs from a Transmitter to a DXLink Input Board and from a DXLink Output Board to a Receiver can each be up to 328 feet (100 m).

Installation and Setup

Hardware Reference Manual – DXLink Twisted Pair™ Transmitters/Receiver

TIP: For systems with special requirements – Before installing in the f inal location, place the equipment close together, so that the destination monitor and a PC for control can be seen simultaneously if adjustments are necessary. Scaling adjustments can be made using SEND_COMMANDs (see page 64). For Enova DGX 8/16/32/64 Switchers, DGX Configuration Software can also be used to make scaling adjustments via the switcher (see the switcher’s manual). For Enova DGX 100 Series Switchers, scaling can also be adjusted via the System Configuration interface (see the switcher’s manual).

CAUTION:

Be careful not to create a network (Ethernet) loop. To avoid doing so, see page 33.

Custom EDID Settings

If Transmitters are part of an Enova DGX system which requires custom EDID settings, see the switcher’s manual for

information on the EDID programming functionality in DGX Configuration Software (available at www.amx.com

SEND_COMMANDs can also be used (see page 64).

If Receivers are part of an Enova DGX 8/16/32/64 system which requires scaler control and settings, see the switcher’s

manual for information on the scaling functionality in DGX Configuration Software (available at www.amx.com

SEND_COMMANDs can also be used (see page 64).

Extender Mode (Standalone): Example of Typical System Setup

A Transmitter and Receiver standalone pair can also work together as an extender solution for transmission of HDMI over twisted pair cable up to 328 feet (100 m). The standalone setup supports DVI-D signals with the use of a DVI-to-HDMI cable adapter. A DX-TX and DX-RX pair can also support an analog video source.

In systems with a Wallplate TX or Decor Wallplate TX, power can be provided to the units via the DXLink line by connecting a DXLink power injector to the Wallplate and using either the desktop power supply or another DXLink power injector with the DX-RX.

Important Power Considerations for Enova DGX Systems

Local power – Local power (the desktop power supply) always takes precedence over power via the DXLink line from the

switcher. However, if a locally powered unit is connected to a switcher and the local power is lost (i.e., unplugged or turned off), the unit will power down and then automatically power back up using power from the switcher via the DXLink connection (increasing the overall power draw on the switcher). When local power is restored, it automatically replaces the power over the DXLink line.

DXLink power – When modules are being powered by an Enova DGX DXLink board, PDXL-2, or PS-POE-AT-TC (using power

via the DXLink line), to maintain the switcher’s power redundancy, we recommend that you:

Determine the power budget based on the Input/Output boards used and the quantity of powered endpoints (modules);

see below.

Do not use the local DC power jack on the module (even if the local power adapter is turned off).

NOTE: When using DXLink Power from an Enova DGX Switcher, we recommend wiring a technical ground for ungrounded sources/ destinations with respect to the DXLink Transmitters/Receivers and switcher (see page 37).

Power Budget Planning for System Setup with an Enova DGX

NOTE: This section does not apply to the Enova DVX Solutions due to their minimal number of DXLink connections.

Before installing an Enova DGX Digital Media Switcher and connecting any required DXLink Transmitters and Receivers, the total power draw for the system should be calculated in order to maintain the redundancy of the power supplies in the enclosure. (Each Enova DGX enclosure ships with two mutually-redundant power supplies.)

IMPORTANT: If you do not plan to draw power from the Enova DGX enclosure’s power supplies, you must Transmitter and Receiver Modules with local power (desktop power supply) or remote power (DXLink power injector), which always overrides power from the switcher. If that power source is turned off, the DXLink Transmitters and Receivers will reboot and then start drawing power from the switcher.

Hardware Reference Manual – DXLink Twisted Pair™ Transmitters/Receiver

Power Budget Calculation

Calculating the power budget helps determine how many DXLink Transmitters and Receivers can be powered through the Enova DGX Digital Media Switcher while maintaining power redundancy if one of the power supplies should fail. The Enova DGX Configuration Tool is used to determine the switcher’s power budget. Simply enter the types of boards and the number of DXLink Transmitters and Receivers to be powered through the switcher, and the calculator shows the resulting power draw. The Enova DGX Configuration Tool is at www.amx.com/enova.

If more DXLink units are required than the switcher can support while maintaining redundancy, any DXLink Modules can be powered using the provided desktop power supplies or DXLink Power Injectors: PDXL-2 (FG1090-170) or PS-POE-AT-TC (FG423-84).

Wallplate and Decor Wallplate Transmitters must be included in the power calculations unless they are being powered by a DXLink power injector (must be AMX approved).

IMPORTANT: AMX does not support the use of any power supplies other than the provided ones or power injectors other than the ones approved as they may potentially damage the DXLink equipment.

Foregoing Power Supply Redundancy

Depending on particular Enova DGX input and output board configurations, operating over the redundant power supply level may be necessary on a permanent basis for some installations. While foregoing the benefits associated with a redundant power supply should be understood, operating without redundancy is in no way detrimental to the system, as long as both power supplies are operational. In this case, necessary power will be pulled evenly from both supplies. However, the loss of one power supply will result in the system being non-operational from a normal “non-redundant” system capability perspective.

In the Event of a Power Supply Failure

If an Enova DGX power supply fails, check the table below to determine which condition* applies and any actions that may be required:

System Condition Result/Required Action

Within power budget The system will continue to run; okay to leave it powered until the failed

Enova DGX 8/16 and 800/1600

Over power budget The system will continue to run; however, we do not recommend leaving

Within power budget The system will continue to run; okay to leave it powered until the failed

Over power budget The remaining power supply will turn off. If enough DXLink Transmitter

In all of the situations above, the power supply should be replaced as soon as possible to restore power redundancy to the system or to allow the system to become fully operational again. Unless the Enova DGX Digital Media Switcher has exceeded its power budget, it should operate normally with a failed power supply.

* The over power budget condition does no t apply to Enova DGX 64/6400 Switchers (which have four power supplies).

For additional information on power supplies and power supply troubleshooting for an Enova DGX Switcher, see the Installation

NOTE: A network loop is created when an enclosure and one or more DXLink Transmitters or Receivers within the system are connected to a common LAN (or when two DXLink Modules are connected to the same network as a standalone pair).

Avoiding Network (Ethernet) Loops

CAUTION:

Only one connection to a LAN is permitted within a switching system with DXLink support. Network loops must be avoided (see FIG. 17). This applies to systems with DXLink Twisted Pair Modules and/or DXLink Fiber, Duplex units in Bidirectional Mode.

Example

In the example in FIG. 17, a network loop was created when the Enova DGX 16 was connected to a LAN and one of its DXLink Transmitters was connected to the same LAN. The DXLink Transmitter must be disconnected from the LAN. The same problem would also occur if an enclosure and one (or more) of its DXLink Receivers were connected to a common LAN. Remember to avoid

network loops.

Be careful not to create a network (Ethernet) loop.

NetLinx Binding of DXLink Modules or Wallplates with an Enova DGX/DVX

NOTE: If a DXLink module or wallplate has been configured for auto-setup mode and then auto-setup mode has been disabled, the

unit may take longer to appear in NetLinx Studio than expected (1-2 minutes).

DXLink Transmitters and Receivers must have their DIP switch toggles set before they will display as part of an Enova DGX system in NetLinx Studio (v4.0 or later is required). DIP switch information, including settings for common scenarios, is on the next three pages.

In NetLinx Studio, the DXLink TXs and RXs can be bound to the integrated Master by right-clicking on the device and selecting Network Bind/Unbind Device. This is considered the traditional method of binding. If the integrated Master runs on a 100 Series CPU, see the Hardware Reference Manual – Enova DGX 100 Series Digital Media Switchers for auto-setup information (which does not require binding).

To bind DXLink units to Enova DGX integrated Master:

1. Verify the following:

a. Verify that an Ethernet/RJ-45 cable is connected from the Enova DGX Switcher’s integrated Master to the network

(e.g., from the switcher’s LAN 100/1000 port to a LAN).

b. Verify that the target Transmitter or Receiver is connected via its DXLink connector to a DXLink Input or Output Board

(respectively) on the switcher.

c. Verify that the switcher is powered on.

2. Launch NetLinx Studio and open the OnLine Tree.

3. Bind the target Transmitter or Receiver to the integrated Master:

a. Select and right-click the TX or RX. b. From the context sensitive menu, select Network Bind/Unbind Device (be sure the check box is selected). c. Click OK.

Setting DIP Switch #1 to Enable/Disable Access to ICS LAN 10/100 Port

The #1 Toggle is used for enabling/disabling network activity over the physical ICS LAN 10/100 port, which allows Ethernet passthrough. It does not affect network activity over DXLink. (For SEND_COMMANDs to disable/enable ICS LAN functionality, see page 79.)

NOTE: #1 Toggle settings do not apply to Wallplate TX & Decor Wallplate TX – leave #1 Toggle OFF.

TIP: Common setup scenarios and their DIP switch settings are provided in a table on page 36.

#1 Toggle Settings

OFF (default) – When the #1 Toggle is set to OFF, network activity over the ICS LAN 10/100 port is disabled.

ON – When the #1 Toggle is set to ON, network activity over the ICS LAN 10/100 port is enabled.

Setting DIP Switch #2 to Set the DXLink Mode

#2 Toggle can be set to automatically or manually select the DXLink Mode (to either Extender or Endpoint) for a given Transmitter/ Rec eiver Module. Default state for #2 Toggle OFF is au to selection o f DXLink Mode based on connection to another device . When it’s ON, the default is Endp oint Mode (us ed for Master controlled serial/IR data transfer) .

NOTE: #2 Toggle settings do not apply to Wallplate TX & Decor Wallplate TX – leave #2 Toggle OFF.

TIP: Common setup scenarios and their DIP switch settings are provided in a table on page 36.

#2 Toggle Settings

OFF (default) – When #2 Toggle is set to OFF, the Transmitter and Receiver will each auto-discover* what type of DXLink

equipment they are connected to and will automatically self-configure to be in one of two DXLink Modes based on the connection:

Extender Mode – This mode is automatically selected when a TX and RX are connected directly to each other (a

standalone pair). The Transmitter and Receiver act like a simple extender, and serial and IR data is passed through them.

Endp oint Mode – This mode is automatic ally selected when a module is connected directly to a DXLink port on a

switcher. Serial and IR operations are handled by the host providing control of endpoints. The Master’s programming specifies where IR and serial commands are sent (this is handled independently from the routing of the video signals).

* Any time the DXLink connection is re-established or power is cycled on a module, the auto-discovery process will take place, as long as the #2 Toggle remains in the OFF position.

ON – When #2 Toggle is set to ON, the auto-discover feature is disabled and the module can be manually set to either

Endp oint Mode (default) or Ex ten der Mode. In Endpoint M ode, when t he module is conne cted to a switcher or a separate NetLinx Master**, IR and serial operation are only handled via the host.

** When standalone modules require IR and/or Serial control by a separate NetLinx Master, then they need to be in Endpoint Mode. Only one must be connected via the ICS LAN 10/100 port to the Master or to a LAN with the Master on it. This requires #1 Toggle to be ON to enable the ICS LAN port. #2 Toggle needs to be ON to place the modules in Endpoint Mode (if needed), and #3 Toggle needs to be ON to enable network connectivity.

NOTE: On either setting, the DXLink Mode may be set via SEND_COMMANDs (see page 79). When #2 Toggle is set to the OFF position, the auto-discovery process will overwrite the DXLink Mode setting. However, when the #2 Toggle is set to the ON position, autodiscovery is disabled and the mode set by SEND_COMMANDs will persist (i.e., the DXLink Mode setting cannot be overwritten).

Setting DIP Switch #3 for Network Connectivity

The #3 Toggle is used for enabling/disabling network connectivity (IP addressing) of the DXLink Transmitter or Receiver. If enabled it allows the Transmitter or Receiver to be conf igured to connect to a NetLinx Central Controller (used for controlling the DXLink unit and allowing Ethernet traffic).

NOTE: Wallplate TX – Before the DIP switch toggles can be set, the mounting bracket must be removed (unscrew the four screws from the bracket and set it aside). Decor Wallplate TX – Set switches before adding customer provided decor style front cover plate (requires four screws).

TIP: Common setup scenarios and their DIP switch settings are provided in a table on the next page.

#3 Toggle Settings

OFF (default) – When the #3 Toggle is set to OFF, the Transmitter or Receiver will not try to connect to the network and will

not acquire an IP address.

ON – When the #3 Toggle is set to ON, the Transmitter or Receiver will attempt to connect to the network via DHCP or static

IP, depending on how the unit has been set up (see page 49). The Transmitters and Receivers will not display in NetLinx Studio and will not accept commands or queries unless the #3 Toggle is ON.

NOTE: After the #3 Toggle is set to ON, a network connection is established, and the NetLinx Studio screen is refreshed, Transmitters and Receivers display in the OnLine Tree as Unbound NDP (Network Detect Proxy) Devices. To facilitate IRL and KIT f ile transfers, th ey can be bound to the integrated NetLinx Master in a switcher or to another NetLinx Master. A Virtual NetLinx Master can also be used for file transfers.

Attaching a Ground Wire to DXLink Transmitters/Receivers

NOTE: Technically this type of grounding is only required when a DXLink Transmitter or Receiver is connected to an ungrounded

device, but this added grounding measure can be used at the discretion of the installer.

If the system is experiencing problems with delivery of DXLink signals to/from an Enova DGX Digital Media Switcher or Enova DVX Solution, adding a ground wire from the TX/RX to the switcher may improve performance. The problem is likely caused by the use of a single phase powered system that does not provide an earth ground for a source or destination’s chassis and shields. This can inject unnecessary AC voltage on the HDMI cable shield that can lead to DXLink signal integrity issues. To check for indications of this type of power in the system, look for a two pronged plug or a cord that has only two wires.

Items Required

□ Phillips #1 screwdriver □ 6 foot ground wire with ring terminal ends (provided)

NOTE: Currently shipping DXLink Transmitters and Receivers provide a designated ground location on the rear of the chassis for attaching a ground wire. For instructions on attaching a ground wire to DXLink Modules without a designated ground location, see page 114.

Attaching a Ground Wire to a Common Earthed Ground

Connect the running end of the ground wire (fixed end attached to a DXLink Transmitter or Receiver) to a common earthed ground (ideally, referenced to the Enova DGX Switcher or Enova DVX Solution).

IMPORTANT: If one DXLink Transmitter or Receiver is grounded, any remaining ungrounded units that are connected to the same board on the Enova DGX Switcher must

Important Twisted Pair Cabling Requirements and Recommendations

The following requirements and recommendations apply to cabling DXLink (RJ-45) connectors:

DXLink cable runs require shielded category cable (STP) of Cat6 (or better).

DXLink twisted pair cable runs for DXLink equipment shall only be run within a common building.*

DXLink delivers 10.2 Gb/s throughput over shielded category cable. Based on this bandwidth requirement, we recommend

following industry standard practices designed for 10 Gigabit Ethernet when designing and installing the cable infrastructure.

The cables should be no longer than necessary to reach the end-points. We recommend terminating the cable to the actual

distance required rather than leaving any excess cable in a service loop.

For complete cable specifications, see page 23.

For more details and helpful cabling information, reference the white paper titled “Cabling for Success with DXLink” available at www.amx.com

or contact your AMX representative.

* “Common building” is defined as: Where the walls of the structure(s) are physically connected and the structure(s) share a single ground reference.

Twisted Pair Cable Pinouts

The pinout in FIG. 26 is for twisted pair cable that connects to the ICS LAN 10/100 connector or to the DXLink connector on the Transmitters and Receivers. Use either the T568A or T568B pinout specification for termination of the twisted pair cable used between the modules in a standalone setup or between Transmitters and Receivers and an enclosure in a full system

FIG. 26 Twisted pair cable pinouts for Ethernet connectors

In a typical installation, the cables should be stretched to their full length between Transmitters and Receivers and the enclosure or between modules in a standalone system. Service loops or coils of the cable may reduce the overall cable performance and should be minimized whenever possible.

Audio Type Precedence

The connectors for bringing audio into the system on the Transmitters are as follows:

HDMI In co nnector – Emb edded audio signal

Digital Audio In jack – Digital audio signal (S/PDIF); not available on the Wallplate TX and Decor Wallplate TX

Stereo Audio In jack – Analog stereo audio signal

The hierarchy for audio type precedence* is listed in the following table for the Transmitters:

Audio Type Precedence on Transmitters

Incoming Signal Audio Type Selected

HDMI w/ embedded digital au dio HDMI w/ Embedded dig ital au dio

S/PDIF digital audio only (not applicable for Wallplate TX and Decor Wallplate TX)

Stereo audio only Stereo audio

* Audio precedence as specified in the table above is applicable when the AUDIN_FORMAT_AUTO command is set to ENABLE; this precedence can be overridden by SEND_COMMANDs (see page 72).

The audio selected by the Transmitters is embedded on the HDMI signal (if not already embedded ) and sent to the switcher (or to DX-RX in a standalone pair) via the DXLink cable.

The DX-RX will take the embedded audio it receives from a Transmitter** and output the following types of audio:

HDMI Out connector – Embedded digital audio signal

Stereo Audio Out connector – Analog stereo audio signal

** These exceptions apply: In order for audio to be sent out of the analog stereo audio connector on the DX-RX, the audio must have originated or be embedded in the HDMI signal on the Enova DGX Digital Media Switcher, Enova DVX Solution, or Transmitter as a 2 channel signal (either analog stereo or 2 channel L-PCM). Multi-channel (>2 channel) L-PCM formats will pass incomplete audio (only 2 of the multiple channels will be sent). All other audio formats will be muted at the connector.

DX-TX or HDMI TX – Applying Power

IMPORTANT: If desktop power is used to power the Transmitter, only the provided desktop power supply should be used and it must

not be altered in any way. Remote power can only be provided via a switcher or a DXLink power injector. AMX does not support the use of any other power supplies or power injectors as these may potentially damage the DXLink equipment.

Important Power Considerations for Enova DGX Systems

Local power – Local power (desktop power supply) always takes precedence over power via the DXLink line from the

switcher. However, if a locally powered module is connected to a switcher and the local power is lost (i.e., unplugged or turned off), the module will power down and then automatically power back up using power from the switcher via the DXLink connection (increasing the overall power draw on the switcher). When local power is restored, it automatically replaces the power over the DXLink line.

DXLink power – When modules are being powered by an Enova DGX DXLink board or DXLink power injector (using power via

the DXLink line), to maintain the switcher’s power redundancy, we recommend that you:

Determine the power budget based on the Input/Output boards used and the quantity of powered endpoints (modules);

NOTE: When using DXLink Power from an Enova DGX Switcher, we recommend wiring a technical ground for the ungrounded sources/ destinations with respect to the DXLink Transmitters/Receivers and switcher (see page 37).

see page 31.

Do not use local DC power jack on module (even if local power adapter is turned off ).

Serial Data Transfer and IR Flow Control

The illustration in FIG. 33 shows the bidirectional serial data transfer and IR flow control when DXLink Mo dules are used in Endpoint Mode with an Enova Digital Media Switcher. The switcher has an integrated NetLinx Central Control Processor which provides native AMX control at each remote location fed by a DXLink Transmitter or Receiver. Control is sent over twisted pair cable (via the DXLink ports). This also holds true when Enova DVX Solutions are used.

FIG. 33

Serial data transfer and IR flow control

Optional: DX-TX, HDMI TX, and DX-RX – Wiring for Serial Data Transfer

The RS-232 (serial) ports are the 3-position screw terminal blocks on the rear of the modules to the right of the ICS LAN 10/100 connector. Wire these ports to supply serial data along with the associated video and audio signals from a source device (over the twisted pair cable between the DX-TX or HDMI TX and the DX-RX) to a destination device or vice versa from the DX-RX to the DX-TX or HDMI TX. In additi on to being directl y co nnected to a device, this port can be connected as an independent native NetLinx control port from a networked NetLinx Central Controller.

IMPORTANT: For serial strings to pass through a standalone TX and RX pair (in Extender Mode) without a NetLinx Master acting as the host, DIP switch #2 Toggle must

The RS-232 port labels are relative to the data flow. On the DX-TX or HDMI TX, data enters the system at the RX label and leaves the system at the TX label on the Receiver (FIG. 34). The flow is reversed from the Receiver to the Transmitter.

NOTE: On both modules, the RS-232 connector pinout is “TX - RX - Ground.”

To wire the RS-232 (serial) connectors on the modules for data transfer:

1. Wire the RS-232 connectors on the modules according to the pinou t directly above the connector.

FIG. 34 Wire RS-232 ports for serial data transfer

2. Use the command RXON to enable this port on the Transmitter and the Receiver. (For complete Serial SEND_COMMAND programming information, see page 76.)

be set to OFF on each module.

Serial Control – Endpoint Mode and SEND_COMMANDs

In Endpoint Mode (modules are connected to a switcher), serial operations are handled by the host providing control of the endpoints. The Master’s programming specifies where the serial commands are sent (this is handled independently from the rou ting o f the video sig nals). For additional inform ation on Endpoint Mo de, see page 28. Fo r Serial SEND_CO MMAND s, see page 76.

Installation and Setup

Hardware Reference Manual – DXLink Twisted Pair™ Transmitters/Receiver

Optional: DX-TX, HDMI TX, and DX-RX – IR Control

For additional information on the IR03 and CC-NIRC, which are required for IR control, see page 19. (The IR03 and CC-NIRC are not included with the modules.) A compatible remote control unit can also be used with the system. In addit ion to being directly connected to a device, this port can be connected as an independent native NetLinx control port from a networked NetLinx Central Controller.

IMPORTANT: When a Transmitter and Receiver are used as a standalone pair, the IR control will be passed through directly in Extender Mode when #2 Toggle is set to OFF (default). When #2 Toggle is set to ON, the Master handles the IR control. When a Transmitter and Receiver are connected to a switcher, they will default to Endpoint mode and the integrated Master handles the SEND_COMMANDs.

The IR Receiver is connected to the IR RX port on the Transmitter, and the IR Emitter is connected to the IR TX po rt o n the Receiver, or the connections can be reversed.

IR03 External IR Receiver (not included)

FIG. 35

IR Receiver cable (FG-IR03)

To connect an IR Receiver to a module:

1. Connect the jack on the IR03 External IR Receiver Module cable (FG-IR03) to the IR RX port on the module.

2. Run the cable and attach the IR receiver bud so that it has a clear line-of-sight with the intended remote control device.

CC-NIRC NetLinx IR Emitter Cable (not included)

FIG. 36 IR Emitter cable (FG10-000-11)

To connect an IR Emitter to a module:

1. Connect the Phoenix connector on the CC-NIRC NetLinx IR Emitter cable (FG10-000-11) to the IR TX port on the module.

2. Run the o ther end of the IR Emitter cable to the display device and locate the IR window.

3. Attach the IR Emitter bud over the device’s IR sensor by removing the cover on the reverse side of the Emitter and sticking the bud directly over the IR window.

IMPORTANT: For systems that include a switcher – when installation of the IR Receiver and IR Emitter is complete, load the appropriate driver (for instructions, see page 60) and program the IR remote according to the product’s documentation.

IR Control – Endpoint Mode and SEND_COMMANDs

In Endpoint Mode (modules are connected to a switcher), IR operations are handled by the host providing control of the endpoints. The Master’s programming specifies where the IR commands are sent (this is handled independently from the routing of the video signals). For additional information on Endpoint Mode, see page 28. For IR SEND_COMMANDs, see page 73.

ID Pushbutton Functions

The ID Pushbutton is located on the right front of the modules, on the left edge of the Wallplate TX, and on the front of the Decor Wallplate TX.

The ID Pushbutton can be used to perform four types of initial configuration settings:

Toggle between DHCP and static IP addressing

Assign a device address

Reset the factory default settings

Restore the factory firmware image

The functions performed depend on when and for how long the ID Pushbutton is pressed and held. For complete ID Pushbutton information, see page 56.

NOTE: ID Pushbutton functions can also be implemented using Telnet commands (see page 90).

DX-RX Scaling Button and Scaling Modes

The Scaling button is located on the front of the Receiver Module. Pressing the Scaling button cycles the module through the three scaling options: Bypass, Auto, and Manual.

Bypass Mode – allows the video signal to display over the destination device without altering the signal’s resolution.

Au to Mode (default) – allows the destinatio n device to cho ose the resolution it needs (this mode is AMX’s SmartScale

Tech n o logy i n a c tion).

Manual Mo de – allo ws the user to conf igure the reso lutio n that the video will di splay throu gh a destination de vice.

Selecting a Scaling Mode results in the module maintaining or altering the source device’s resolution as it is passed along to the destinatio n device.

The Scaling Mode can be set on the DX-RX with the Scaling button (see instructions below), with DGX Configuration Software, or with SEND_COMMANDs (see page 66).

To set the scaling option (mode):

1. Press the Scaling button on the DX-RX once or twice until the LED for the desired scaling option illuminates solid green.

Bypass Mode

Bypass Mode allows the video signal to display over the destination device without altering the signal’s resolution.

NOTE: Interlaced and progressive video are supported into the Transmitters; progressive is only supported out of the Receiver unless it is in the Bypass mode, which is non-scaling.

Auto Mode

At initial power up, the DX-RX defaults to the Auto scaling option.

NOTE: When the output cable is disconnected from the DX-RX or if no EDID can be found on the destination device, the last used Scaling Mode LED will be ON. In either case, the DX-RX will continue to hold its out put resolution to the last known preferred resolution until a power cycle or reconnection of a sink with a valid EDID. On power up without a valid EDID, the default preferred output resolution presented will be 1280x1024,60Hz until a different EDID is detected.

Manual Mode

Man ual Mode al lows the user to conf igure the reso lutio n that t he video will display th rough a destinatio n device. Manual M ode defaults to 1280x1024p,60Hz. This default resolution can be changed in two ways:

Use the SEND_COMMAND VIDOUT_RES_REF to set the resolution and refresh rate (for details, see page 66).

When used as a direct output of an Enova DGX DXLink Output Board, use DGX Configuration Software to set and persist the

Manual scaling resolution for the connector on the DXLink Output Board; the DXLink Output Board sends the scaling resolution data to the DX-RX.

NOTE: The scaling mode (and the aspect ratio) can also be set on the DXLink Output Board using DGX Configuration Software. The data is persisted on the board and sent to the DX-RX.

Persistence of Scaling Options

The DX-RX defaults to “Auto” when power is cycled. The scaling option can be persisted using one of the following methods:

Using the SEND_COMMAND: PERSISTAV (for details, see page 79).

Using DGX Configuration Software to set and persist the scaling option for the connector on the DXLink Output Board on

the Enova DGX Digital Media Switcher; the DXLink Output Board sends the scaling option data to the DX-RX.

DXLink TX/RX in a Multiple-Stage Switching System

When switching systems with DXLink Technology support (e.g., an Enova DGX Digital Media Switcher and an Enova DVX-3155HD) are connected via their DXLink ports, DXLink Transmitters and Receivers can be used to extend the video and audio transport.

IMPORTANT: This section does not refer to the linking of enclosures from CPU to CPU, which is not Media Switcher or the Enova DVX Solutions.

In an installation with DXLink equipment in a multiple-stage switching system, the following apply:

Network loops must be avoided (see page 33). The DXLink line’s Ethernet functionality is disabled between the enclosures;

therefore, no IR, serial, or Ethernet communication can be passed between them.

When two switching systems with DXLink support are connected via their DXLink ports, only video and audio will be passed

through the DXLink connection.

When a DXLink input or output on one switching system determines that it is connected to a DXLink input or ou tput on

another switching system, the DXLink port will au tomatically disable all Ethernet, power, and control on that connection port so that the only things passed down the DXLink line are the video and audio signals.

When connecting switching systems via DXLink ports, AMX recommends no more than three switcher throughputs (see the

“Example” below).

Example

This example shows how DXLink Transmitters and Receivers can be used in a system where switchers are connected via their DXLink ports.

Network Conf iguration

Overview

IMPORTANT: If the TXs/RXs are connected to an Enova DGX 100 Series Switcher using auto-setup, see the “Hardware Reference

Manual – Enova DGX 100 Series Digital Medial Switchers” for network conf iguration information.

NOTE: If a DXLink module or wallplate has been configured for auto-setup mode and then auto-setup mode has been disabled, the unit may take longer to appear in NetLinx Studio than expected (1-2 minutes).

DXLink Modules support two IP Addressing Modes: Static IP and DHCP (with link-local fallback*).

To avoid having a large system consume numerous IP addresses, the Transmitter and Receiver default to disabling the network connection functionality. Therefore, the #3 Toggle must be set to ON before the Transmitter or Receiver can establish a network connection (see page 35).

When #3 Toggle is ON, the DXLink Modules are automatically placed in DHCP Mode, but they can be conf igured for either of the IP Addressing Modes via two methods:

The front-panel ID Pushbutton (see page 56)

Telnet commands (see page 90)

* “Link-local fallback” is a method by which an IP host, as a fallback from DHCP, can derive a local network-unique IP address by negotiating with the other IP hosts on the same network. Link-local can also be used in its own right as the primary method of IP address allocation. For details, see “DHCP Mode” below.

Static IP Mode – Default Parameters

Network Configuration

IMPORTANT: Static IP Mode will not function until the #3 Toggle on the DIP switch is set to ON (see page 35). The #3 Toggle must be ON before the device is accessible via SEND_COMMANDs.

Default Parameters for Static IP Mode

Address 192.168.1.2

Netmask 255.255.255.0

Gateway 192.168.1.1

DNS1 192.168.1.1

DNS2 192.168.1.1

DNS3 192.168.1.1

DHCP Mode

IMPORTANT: DHCP Mode will not function until the #3 Toggle on the DIP switch is set to ON (see page 35). The #3 Toggle must be ON

before the device is accessible via SEND_COMMANDs.

DHCP Mode requires a connection to a network with a DHCP server located on it. This connection can be either indirect or direct.

Indirect connection – In the case of an Enova DGX Digital Media Switcher or an Enova DVX Solution (Endpoint Mode) that

is connected to a DHCP server device, the DHCP connection can be propagated through the system’s DXLink layer. First you must complete the following:

Set the #3 Toggle to ON to enable the network connectivity.

Direct connection – In the case of a st andalone pa ir (Extende r Mode) , to place th e DXLink Mo dules in DHCP Mo de yo u must

complete the following:

Set the #1 Toggle to ON to enable access to the physical ICS LAN 10/100 port. Set the #3 Toggle to ON to enable network connectivity (DHCP). Connect the ICS LAN 10/100 port to a network where a DHCP server is located.

When in DHCP Mode (default setting), the module will attempt to get a DHCP lease (consisting of IP address, gateway, and other network parameters). Should the attempt fail, the module will then configure itself for a link-local address.

DXLink Modules utilize a modified link-local addressing procedure. The f irst address to be tried is a known address in the

link-local space: 169.254.2.2. That add ress will be probed, and if unclaimed will be used by the DXLink Module.

If 169.254 .2.2 is already claimed, the DXLi nk Module will c hoose a ra ndom add ress within the 169.254.x.x link-local address

space (again probing to ensure that it is unclaimed).

Once the module is operating with a link-local address, it will periodically re-try DHCP and re-assign the IP to a valid DHCP grant if successful.

At any time, if the module determines that its IP address has changed, it will disconnect from the Master (if necessary, depending on the connection state) and then reconnect to the Master.

Network Configuration

Hardware Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver

TCP/IP Address Conf iguration

DXLink Modules support IPV4 network addresses, gateway addresses, DNS server addresses, and network names. They also support NDP (NetLinx Discovery Protocol) capabilities as well as IP discovery via NetLinx Studio.

NOTE: NDP is a device discovery method used by NetLinx Masters. With NDP Beacon enabled, the Master will transmit NDP Beacons for AMX’s proprietary device discovery.

Telnet IP Conf iguration Commands

The SET IP and GET IP Telnet commands listed in the tables in Appendix B (which start on page 91) can be sent directly to the device via a Telnet terminal session. These commands can be used for initial network configuration o f the DXLink Modules.

The default Telnet port is 23.

Telnet is e nabled by default.

A value of 0 disables the telnet server.*

For details, see “Appendix B – Telnet (Terminal ) Commands” on page 90. The appendix also includes a section on “Master Connection Modes” on page 97.

* If you set the Telnet port to “0” to disable it, you will need to perform a factory reset using the ID Pushbu tton to re-enable it (see page 57).

External Master Versions

If the DXLink Module is bound to an external Master, we recommend using the versions listed in the table below, which can be found on the product’s page at www.amx.com

Offline Recovery Mechanism for DXLink Devices

Offline Recovery Mechanism – A new, optional, recovery mechanism for DXLink devices in the rare occurrence that these devices

move from online to offline status for an extended period of time.

The default setting for the recovery mechanism is OFF, but may be enabled for environments where the DXLink device could lose connectivity to the Master for 5 minutes or longer.

IMPORTANT: A reboot is required after setting the recovery mechanism before the new setting takes effect.

The following Telnet Commands enable, disable, and query the Offline Recovery Mechanism:

Set recovery mechanism to ON: WD ON

Set recovery mechanism to OFF: WD OFF

Query recovery mechanism’s current status: WD

Once the device’s recovery mechanism is set to the ON state via Telnet, the recovery mechanism monitors the ICSP connection to the Master. The recovery mechanism is not armed until the DXLink device is brought online. Entering an offline state triggers an internal timer in the DXLink device which, after 5 continuous minutes in the offline state, in turn triggers the recovery mechanism to issue a full reboot command to the DXLink device. During this time the DXLink device will reboot and all functions (including video and audio delivery) will be disabled while th e reboot occurs. This process takes up to 45 seconds to complete.

This functionality is an option intended to be a safety net for the rare occasions when a device falls offline and remains there for a long enough period of time that the likelihood of the device coming back online on its own diminishes. The reboot is intended to restart the device and allow it another opportunity to connect with the Master it is bound to.

Usage considerations include:

Once a device reboots, the recovery mechanism will not become armed again until the device reaches an online state

with a Master.

Because video is lost during the reboot process, consideration should be given to certain installation designs where a

Master or the network connection between the Master and a DXLink endpoint might regularly be disabled or turned off, but video might continue to flow through the DXLink device. In these environments, we recommend not enabling the Offline Recovery Mechanism.

Additional capabilities of recovery mechanism – Although highly unlikely, the recovery mechanism also monitors the

following states and provides a self-recovery mechanism if these states are ever encountered.

If a DXLink device processor enters an unstable processing condition If the DXLink device’s allowable minimum memory threshold is exceeded

Using the ID Pushbutton

The ID Pushbutton is located on the right front of the modules, on the left edge of the Wallplate TX, and on the front of the Decor Wallplate TX.

FIG. 37 ID Pushbutton on module (HDMI TX shown)

The ID Pushbutton can be used to perform four types of initial configuration settings:

Toggle between DHCP and static IP addressing (see below)

Assign a device address (page 57)

Reset the unit to its factory default settings, which affects the parameters but not the f irmware version (see page 57)

Restore the unit to its factory firmware image, which affects both the firmware version and the parameters (see page 58)

The functions performed depend on when and for how long the ID Pushbutton is pressed and held. ID Pushbutton functions can also be implemented using Telnet commands (see page 90).

TIP: To monitor the ID Pushbutton boot state of a module by its NetLinx LED behavior, see page 59.

Toggling Between IP Addressing Modes: DHCP and Static IP

DXLink Transmitters and Receivers support both DHCP and static IP addresses. When the #3 Toggle is ON (see page 35), the modules automatically use DHCP with link-local fallback. However, you can use a static IP address which can be set via a Telnet command (SET IP), or you can use the factory default static IP address. The default static IP address can be recalled at any time by resetting the unit to its factory default conf iguration (see page 57). The default dynamic (DHCP) address is 169.254.2.2.

The ID Pushbutton can be used to toggle between the DHCP and Static IP Modes.

To toggle between DHCP and Static IP Modes:

1. Once the module has booted up, press and hold the ID Pushbutton until the Control/NetLinx LEDs toggle back and forth in unison approximately 10 times.

2. Release when it starts to blink faster.

When the Pushbutton is released, the module toggles either from static to dynamic (DHCP) IP addressing or vice versa and

remains in that mode until the ID Pushbutton is used to set it again or a factory reset is performed.

The module automatically reboots to complete the process.

Network Configuration

Hardware Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver

Assign a Device Address (ID Mode)

The ID Pushbutton can be used in conjunction with the ID (Identify) Mode feature in NetLinx Studio. A momentary press of the ID Pushbutton assigns a device address to the Transmitter or Receiver (which must be bound to the Master). The device must first be placed in ID Mode in NetLinx Studio or the momentary press will be ignored.

NOTE: The latest version of NetLinx Studio is available to download and install from www.amx.com help for instructions on using the application.

To set the device address on a Transmitter or Receiver:

1. Check to be sure #3 Toggle on the bottom of the Transmitter or Receiver is set to ON.

2. In NetLinx Studio’s OnLine Tree, select the Master to which the Transmitter or Receiver is bound.

3. From the Diagnostic menu, select Device Addressing.

The Device Addressing dialog box opens.

. Refer to the NetLinx Studio online

4. In the ID Mode section, enter the Device and System numbers that you want assigned to the device in the appropriate text boxes.

5. Click Start Identify Mode to place the named system in ID Mode.

The button changes to “Cancel Identify Mode” (click to cancel ID Mode). The text box below the button displays a “Waiting...Press Cancel to Quit” message.

NOTE: When in ID Mode, the entire system is put on hold while it waits for an event from any NetLinx device in the named system (e.g., pressing the ID Pushbutton on the Receiver). The device that generates the first event is the device that will be “identified.”

6. Briefly press and release the ID Pushbutton on the Transmitter or Receiver.

The Transmitter or Receiver will exhibit the following behavior:

Respond with an ID Mode address response.

Report its old address offline.

Report its new address online.

The OnLine Tree will refresh to display the new device address for the Transmitter or Receiver.

NOTE: NetLinx Studio (v4.0 or later) provides the ability to auto-increment IP Addresses and Hostnames as well as Device and System

Numbers. Refer to the NetLinx Studio online help for details.

Reset the Factory Default Settings

During power up – if the ID Pushbutton is held until the Control/NetLinx LEDs toggle back and forth in unison approximately 10 times, then released when the faster blinking starts, the Transmitter or Receiver will reset to its factory default settings, which affect the parameters but not the firmware version.

Factory Parameters*

Default static IP address of 192.168.1.2

Default dynamic (DHCP) address of 169.254.2.2

Default device number of 0

NDP mode (see page 97)

Unbound state

No IRL files

* For a complete list of factory parameters, see the table on page 55.

Instructions for the modules are given first followed by the instructions for the Wallplate TX and the Decor Wallplate TX, which receive power over DXLink from the switcher.

IMPORTANT: If a Transmitter or Receiver Module is receiving power from a switcher, disconnect the DXLink connector on the module and reattach to apply power.

Network Configuration

Hardware Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver

To reset a Transmitter or Receiver Module to its factory default settings:

1. Press and hold the ID Pushbutton while plugging in the power connector. Start counting when the NetLinx LEDs begin to flash in unison, not when the power connector is inserted.

Once the Transmitter or Receiver Module has started booting up, both NetLinx LEDs flash in unison at the rate of once per

second.

After 10 flashes at that rate, the LEDs will blink in unison at a faster rate.

NOTE: A press-and-hold of the ID Pushbutton at power up will prevent the Transmitter or Receiver from attempting to come online until the ID Pushbutton is released. The Transmitter or Receiver will only attempt to come online if you release the Pushbutton prior to the faster blink rate.

2. At the point that the blink rate increases, release the ID Pushbutton.

The Transmitter or Receiver will automatically reboot to complete the process.

To reset Wallplate TX or Decor Wallplate TX to its factory default settings:

1. The ID Pushbutton and the Reset button are located on the left edge of the Wallplate TX and on the front of the Decor Wallplate TX.

2. Press and hold the ID Pushbutton. While the ID Pushbutton is down, press and release the Reset button. Start counting when the NetLinx LEDs begin to flash in unison, not when the Reset button is released.

Once the unit has started booting up, both NetLinx LEDs (on bottom edge) flash in unison at the rate of once per second.

After 10 flashes at that rate, the LEDs will blink in unison at a faster rate.

NOTE: A press-and-hold of the ID Pushbutton at boot will prevent the unit from attempting to come online until the ID Pushbutton is released. The unit will only attempt to come online if you release the Pushbutton prior to the faster blink rate.

3. At the point that the blink rate increases, release the ID Pushbutton.

The unit will automatically reboot to complete the process.

TIP: In the following two procedures – if you start a press and hold sequence with the ID Pushbutton and then decide not to change the settings, before you release the ID Pushbutton remove power from the unit to abort the procedure (remember, power can be applied via the external power supply or over DXLink, so one or both sources of power may need to be removed).

Restore the Factory Firmware Image and Factory Default Parameters

During power up – if the ID Pushbutton is held until the Control/NetLinx LEDs toggle back and forth in unison approximately 30 times (10 slow, 20 fast) and then released when they go solid, the module’s factory firmware image will be restored. Th is procedure affects both the f irmware version and the parameters.

Instructions for the modules are given first followed by the instructions for the Wallplate TX and the Decor Wallplate TX, which receive power over DXLink from the switcher, PDXL-2 (FG1090-170), or PS-POE-AT-TC (FG423-84).

IMPORTANT: If a Transmitter or Receiver Module is receiving power from a switcher, on the module disconnect the RJ-45 cable from the DXLink connector before starting the instructions below.

To restore the Transmitter or Receiver Module to its factory default f irmware image:

1. Press and hold the ID Pushbutton while plugging in the power connector (if the power source is a switcher, plug in the RJ-45 connector into the DXLink port instead). Start counting when the NetLinx LEDs begin to flash in unison, not when the power connector is inserted.

After the LEDs complete the following sequence, release the ID Pushbu tton:

Once the Transmitter or Receiver has started booting up, all LEDs flash in unison at the rate of once per second.

After 10 flashes at that rate, the LEDs will blink in unison at a faster rate.

After 10 seconds of flashing at the increased rate, all LEDs go to solid on.

2. Upon release of the ID Pushbutton, the Transmitter or Receiver executes the following actions:

a. Restores itself to its factory firmware image. b. Resets to factory default parameters*:

Deletes all IRL f iles sto red on t he device.

Resets to the default static IP address of 192.168.1.2 and default DHCP address of 169.254.2.2.

Resets to the default device number of 0 (when bound to a Master, receives a dynamic device number from the Master).

Resets to NDP mode and being unbound.

3. Once all actions in Step 3 are completed, the LEDs all turn off, indicating the Transmitter or Receiver is ready to reboot.

The Transmitter or Receiver automatically reboots to complete the process.

* For a complete list of factory parameters, see the table on page 55.

Aspect Ratio Options

Stre tch (to f it) – This option (default) scales the video to full screen size in both horizontal and vertical directions regardless of the

input aspect ratio. No data is cropped. However, the image may be distorted as needed to fill the screen. When Stretch is selected, black bars are not added by the scaler. However, if an image has originated from a source device with either horizontal or vertical black bars (e.g., letter box from a movie), the black bars will be considered as active video and will be included in the stretched video.

Maintain (aspect ratio) – This option maintains the incoming video’s aspect ratio, but will scale the image until the display fills either horizontal or vertical direction first. If the vertical direction is filled first, then the video will have pillar box black bars on the sides of the display. If the horizontal direction is filled first, then the video will have letter box black bars on the top and bottom of the display.

Zoom – This option maintains the input aspect ratio while zooming the image to fill the screen in all directions. Image data may be lost on the top and bottom or to the left and right of the displayed image.

Anamorphic – This option is used with anamorphic formatted video sources so that images appear correctly on the display.

Troubleshooting

Overview

The troubleshooting suggestions/strategies provided apply to the Transmitters and the Receiver, unless otherwise noted.

Five potential types of issues are covered in this chapter:

Basic troubleshooting

Determining HDCP compliance

Power

DXLink connections

Network setup

This chapter also provides technical support contact information on page 85.

Basic Troubleshooting

We suggest using the following general list to rule out basic troubleshooting issues.

□ Check the power indicator LEDs on all of the equipment. If any are not illuminated, see the “Power Issues” section below. □ Check all link and signal connections to make sure everything is physically set up correctly. □ Isolate source and destination equipment and cable problems by cabling direct without the DXLink units. □ Check the DIP switch’s toggle settings (see page 34). □ SEND_COMMANDs – double-check the command and the port number specif ied and re-send the command (see page 64). □ If any changes have been made, try resetting the unit to the factory defaults (see page 57).

Additional Resources for Troubleshooting Switching Systems

Enova DGX Digital Media Switchers

When the DXLink units are used in conjunction with an Enova DGX Switcher, we suggest checking the troubleshooting information in that product’s manual.

Enova DVX Solutions

When DXLink units are used in conjunction with an Enova DVX Solution, we suggest: pressing the Status button on the front panel and using the UP and DOWN navigational buttons to scroll through the menu options to Diagnostic Codes (the codes can be helpful for technical support if a call is necessary).

Tro ub le sh oo tin g

Determining HDCP Compliance

A dark red or an o range screen on an outpu t display is the visual cue f rom DXLink devices that the display device cannot display the HDCP compliant signal from the source.

Power Issues

Upon power up, the Power indicator LED on the front of the DXLink units illuminates solid green.

If the Power LEDs on any of the system’s equipment are not illuminated:

□ Check the power cords or DXLink (RJ-45) connection if using power over the DXLink line. □ Check the power connections on the switcher if using power over the DXLink line. □ Check the power connections on the source and destination devices.

DXLink Power Delivery Issues

Unexpected power interruptions o f DXLink Transmitters and Receivers may be caused by the Enova DGX Digital Media Switcher being powered by single phase power. Connecting a ground wire to the DXLink unit’s chassis and a common earthed ground (ideally, referenced to the switcher) will stop power interruptions. For information on when and how to attach ground wires to DXLink units, see page 37.

Hardware Reference Manual – DXLink™ Twisted Pair Transmitters/Receiver

Important Power Considerations for Enova DGX Systems

Local power – Local power (the desktop power supply) always takes precedence over power via the DXLink line from the

DXLink power – When Transmitters/Receivers are being powered by an Enova DGX DXLink board or DXLink power injector

(using power via the DXLink line), to maintain the switcher’s power redundancy, we recommend that you:

Determine the power budget based on the Input/Output boards used and the quantity of powered endpoints

(Transmitters/Receivers); see page 31.

Do not use the local DC power jack on the module (even if the local power adapter is turned off).

Power Issues with Enova DGX Systems

In an Enova DGX System when multiple endpoints (Transmitters/Receivers) cycle their power and the DXLink connection fails, check the following:

□ Check to be sure that Transmitters/Receivers being powered by the local DC jack have power. (Local power always takes

precedence.)

□ Check to be sure that Transmitters/Receivers intended to be powered via the DXLink line do not have a DC jack plugged in

(even if the local power adapter is turned off). This can cause inadvertent ground loops that can negatively affect DXLink power sensing circuits.

DXLink Connection Issues

One method for determining DXLink connection issues is to compare the pattern of the green and yellow DXLink LEDs on the Transmitter or Receiver against the tables below and then check the suggested items in the Troubleshooting column in the second table.

DXLink LED Patterns When Connection is Working as Expected

Check the status of the green and yellow DXLink LEDs (on rear of the modules – on lower edge of the Wallplate TX, or on the front of the Decor Wallplate TX – under customer provided standard decor style cover plate) against the following table to determine the status of the video signal over the DXLink line. All of the green / yellow patterns in this table indicate that the unit is working as expected given its current connections. If the LED pattern does not correspond to any of the green / yellow patterns in this table, check the table below.

LED Patterns – Working as Expected

Green Yellow LED Pattern Description

Solid green Solid yellow The DXLink link is established and the video stream is passing HDCP protected content.

Solid green Flashing yellow The DXLink link is established and the video stream is passing unprotected content.

Solid green Off The DXLink link is established but no video content is being passed.

Off Off The DXLink link is not established and the accompanying DXLink unit is not powered on or is

not connected.

NOTE: For installations where the DXLink Twisted Pair device could lose connectivity for an extended period of time (greater than 5 minutes), the Offline Recovery Mechanism is an option that allows the device to detect its offline state and reconnect to a Master (see page 54).

Network Setup Issues

The instructions below can be used for f irst time setup of DXLink Modules on a network with no NetLinx Master (integrated or standalone).

NOTE: Before setting up the network, we recommend plugging all required Ethernet cables into the network before applying power to the DXLink Modules.

To set the IP, connection, and device parameters on a DXLink Module:

1. Set the DIP switch on the DXLink Module to:

#1 and #3 Toggles – ON

#2 and #4 Toggles – OFF

2. Attach the DXLink Module via its ICS LAN 10/100 port to the network or PC.

3. Power up the DXLink Module.

The DXLink Module will get a DHCP address or default to 169.254.2.2 (or if the module is in Static IP Mode, the address will be

192.168.1.2).

4. Establish a Telnet connection to the DXLink Module and set up the network parameters using the following three commands:

SET IP SET CONNECTION SET DEVICE

5. Enter REBOOT.

6. Reset the DIP switches to conf igure the DXLink Module for the specific type of system setup being used (see the “Common Scenarios” table on page 36).

NOTE: If you cannot locate the DXLink Module in the Online Tree, you can reset the factory default by holding the ID button during power up until the LEDs blink in unison and then releasing the ID button. This will revert the DXLink Module to DHCP mode. Start again at Step 1 above.

1. Check to be sure #3 Toggle on the bottom of the Transmitter or Receiver is set to ON.

2. Verify that you have the latest version of NetLinx Studio on your PC.

If the version is not the latest –

Use the Web Update option in NetLinx Studio’s Help menu to obtain the latest version.

Go to www.amx.com and login as a Dealer to download the latest version.

3. Download the latest Firmware (KIT) f ile from www.amx.com (Place KIT files on a local drive for speedy throughput.)

4. Verify the following:

a. Verify that an Ethernet/RJ-45 cable is connected from the switcher’s integrated Master to the network (e.g., from the

LAN 100/1000 port on an Enova DGX 32 to a LAN).

b. Verify that the target Transmitter or Receiver is connected via its DXLink connector to a DXLink Input or Output Board

(respectively) on the switcher.

c. Verify that the switcher is powered on.

5. Launch NetLinx Studio and open the OnLine Tree.

6. Bind the target Transmitter or Receiver to the integrated Master: select and right-click the TX or RX; from the context sensitive menu, select Network Bind/Unbind Device (be sure the check box is selected); click OK.

on the DXLink Transmitter or Receiver product page to your PC.

7. Determine the Device Number assigned to the target Transmitter or Receiver when it was bound. For the Device Number location, see FIG. 40 on page 86. The Transmitter or Receiver is ready for the KIT file transfer.

Important Upgrade Information

CAUTION:

In the Event of Power Loss During an Upgrade

If power loss occurs before any firmware information has been transferred – when power is restored, the module will remain operational using the original firmware.

If power loss occurs after some of the f irmware information has been transferred but before the transfer is complete – when power is restored, the module will time out and will not operate until a successful upgrade takes place.

CAUTION:

firmware again, as the module is in an unknown state and cannot be guaranteed to be operational.

Upgrading the f irmware is a serious action in that if the upgrade fails, it can leave the system completely non-operational.

If the application signals a failure, you must immediately reboot the Transmitter or Receiver and attempt to upgrade the

The Power LED blinks during the process for upgrading the firmware (this is normal).

The progress of the upgrade displays in the Upload Status field. Status is also indicated in the Status bar at the bottom.

The success of the upgrade or any errors that occur will be reported.*

* If an incorrect file has been selected or if the upgrade has failed, the Power LED will briefly illuminate solid green then change to a slow blink. To recover (in either case), reboot the Transmitter or Receiver and browse to select the correct file and then re-send.

7. Close the window when the transfer is complete.

8. When the process is complete, cycle power using the new image on the DXLink Module:

a. Unplug the desktop power supply from the AC power source and plug it back in.

b. If the power source is the switcher, unplug the RJ-45 connector from the DXLink port on the module and plug it back in.

9. Wait 60 seconds and refresh the System OnLine Tree, and check to be sure the firmware version matches the version selected for the upgrade.

Reminders

When the file transfer is complete, remember to do the following:

Set the #1 Toggle on the DXLink Module to OFF.

If you set the PC to Static IP Mode for a Virtual NetLinx Master file transfer, return the setting to “Obtain an IP address

automatically” (see page 100).

Appendix B - Telnet (Terminal) Commands

Hardware Reference Manual – DXLink™ Twisted Pair Transmitters/Receiver

Appendix B - Telnet (Terminal) Commands

Establishing a Terminal Connection Via Telnet

Te lne t terminal communication is accessed remotely via TCP/IP. The Transmitter or Receiver must have its own TCP/IP address for a Telnet connection. The connection can be started from the Windows taskbar (see below) or in NetLinx Studio (see the following page).

By default, a User Name and Password are not applied to the Telnet port (Port 23). Therefore, the port does not require login credentials.

Welcome Banner with and without Security Enabled:

Witho ut Telnet security enabled, a session wil l begin with a welc ome banner similar to the fo llo wing:

If Telnet security is enabled, user credentials are required:

Enter username: admin Enter protected password: **** Welcome to DXLINK-HDMI-RX 0.0.106.0 Copyright AMX LLC 2011 >

NOTE: When security is enabled, a user can retry logging in three times before being disconnected (for information on setting a username and password, see page 91).

IMPORTANT: If auto-setup mode is being used, Telnet is the only way to access some of the network settings. Also note that some network settings will disable the auto-setup feature (for auto-setup requirements, see the “Quick Reference Table – Modes for Handling Addressing/Networking” on page 20).

To establish a terminal connection via Telnet at the CMD prompt:

1. From your Windows Taskbar (at the far left), select Start > Run to open the Run dialog box.

2. Type

cmd in the Open field.

3. Click OK to open an instance of the Windows command interpreter (cmd.exe).

4. At the prompt (>), type telnet

Example:

>telnet XXX.XXX.XXX.XXX

A Telnet session opens for the Transmitter or Receiver and the welcome banner appears.*

5. At the prompt, type the Telnet command (see the table starting on page 92) and press Enter.

* If you are using Windows 7 and receive an error message, you may need to enable Telnet by completing the following: (1) go to Start / Control Panel / Programs and Features, (2) on the left, select “Turn Windows features on or off,” (3) select the check-boxes Telnet Client and Telnet Server, and (4) click OK.

followed by a space and the Transmitter or Receiver’s IP address.

Appendix B - Telnet (Terminal) Commands

Hardware Reference Manual – DXLink™ Twisted Pair Transmitters/Receiver

To establish a terminal connection via NetLinx Studio:

1. In the Online Tree, select the DXLink unit and right-click to access the short-cut menu.

2. Select Launch Telnet Window via NetLinx Studio. The Telnet window opens and the welcome banner appears.

3. At the prompt (>), type the Telnet command and press Enter.

Telnet Username and Password

The following commands are used to set the Telnet username and password for a Telnet connection:

Set Telnet Username Set Telnet Password

By default, both the username and password are blank (empty strings). Performing a factory reset on the device with the Pushbu tton will return these values to that default. For details, see pa ge 58.

Username – Setting the Username will have no effect if the password remains blank (empty string). That is, defining the

username alone will not result in Telnet prompting for a user login.

Password – Setting the Password will cause Telnet to prompt for a user login, whether the username has been defined or

not. If the username has been defined, this value must be entered. However, since the password can be set independently of the username, it’s possible to have a password def ined, but the username still at its default (blank, empty string). In this case do not enter anything for the username when prompted. Simply press Enter, which will then present the password prompt. Here, the defined password must be entered in order to successfully open the Telnet session.

Additional Notes

Both the Telnet username and password are case-sensitive.

Three consecutive, unsuccessful attempts to log in to Telnet will cause the Telnet window to close.

Re-launching Telnet will again present the login prompt, with a fresh “batch” of login attempts.

If a Telnet login fail s because of an inc orrect username, an “Invalid Password” message will appear

(as opposed to an “Invalid Username” message).

The username and password are saved after reboot or power cycle.

The username and password are deleted/removed after a factory reset.

NOTE: Enova DGX 100 Series Switchers support Telnet commands and BCS commands over Telnet, while Enova DGX 8/16/32/64 Switchers support BCS tunneling access over TCP/IP. For information, see the applicable manual.

Appendix B - Telnet (Terminal) Commands

Hardware Reference Manual – DXLink™ Twisted Pair Transmitters/Receiver

Setting a Telnet Username and Password

To set a Telnet username and password:

1. Establish a terminal connection via Telnet (see page 90).

2. Type Set Telnet Username, and press Enter.

a. The program will prompt you to enter a new Telnet username; enter a username and press Enter. b. The program will indicate that the username is being stored.

3. Type Set Telnet Password, and press Enter.

a. The program will prompt you to enter a password; press Enter twice to clear both the Telnet username and password. b. Enter a password and press Enter. c. The program will prompt you to re-enter the password; re-enter the password and press Enter.

The program will indicate that the password is being stored.

Telnet Commands

The Telnet commands listed in the table below can be sent directly to the Transmitter or Receiver via a Telnet terminal session.

The default Telnet port is 23. A value of 0 (zero) disables the Telnet server.

Telnet is e nabled by default.

Master Connection Modes

The mode of communication used for connection to the Master is specified via the SET CONNECTION Telnet command (see page 95).

Connection mode setting options are AUTO, TCP URL, UDP URL, or NDP (default) as described:

AUTO – This mode utilizes TCP communication. It looks for a matching System Number and attempts to come online with

the first Master it sees with that System Number.

TCP URL – TCP; the Master is specified via URL.

UDP URL – UDP; the Master is specified via URL.

NDP – UDP; this mode utilizes the NDP binding process to assign the DXLink Module (the physical device) to a Master

(or Virtual Master) via NetLinx Studio. Once bound, communications are conducted via UDP.

NOTE: In URL modes, the Master can use either an IP address or a DNS name.

Guidelines

UDP mode is recommended for the following types of installations:

Small-to-medium residential and corporate installations on a single subnet

Segmented control network installations (control network is a separate switching domain and subnet from other network

equipment)

Installations with the total number of NetLinx / ICSNET devices on a single Master exceeding 128

TCP mode is recommended for installations where (a) the switching domain of the network is subject to “bursty” traff ic or heavy streaming activity (>20 Mbps consumption by streaming) and where (b) the total number of NetLinx / ICSNET devices on a single Master is less than 128.

TCP vs. UDP

TCP – Protocol has a built-in retry mechanism.

UDP – Protocol does not have a built-in retry mechanism, but consumes fewer resources on the Master. AMX’s UDP

implementation of NetLinx employs a retry mechanism to provide the reliability of TCP with the resource efficiency of UDP.

Appendix B - Telnet (Terminal) Commands

Hardware Reference Manual – DXLink™ Twisted Pair Transmitters/Receiver

URL vs. NDP vs. Auto

Determining which connection method to use for Master Connection Mo de is essentially a matter of decidin g wh at i nfo rmation the device should use to identify the correct Master to connect to.

The defa ult mode is NDP ; the mode c an be changed via the SET CONNECTION Telnet command (see page 95).

URL – The device connects to the Master with the specified URL. The device must be configured with the URL of a specific

Master via the SET CONNECTION Telnet command (see page 95).

NDP – The device connects to the Master it’s been bound to, which is based on the Master’s MAC address. The binding is

configured via NetLinx Studio. Once bound, the device must be unbound using either NetLinx Studio or the Telnet NDP UNBIND command before being re-bound to a different Master. Alternatively, NDP devices can be bound/unbound via options on the Master’s Web Configuration pages (System > Manage NetLinx). For details, refer to the WebConsole & Programming Guide – NX-Series Controllers (System - Manage NetLinx section).

Auto – The device connects to the f irst Master it finds with the specif ied System Number.

The device must be configured with the desired system number via the SET CONNECTION Telnet command (see page 95).

Use of this method requires that only one Master has any particular system number and is visible to the subnet. If this is the case, then Auto is the simplest choice. However, with Auto, you are not hard-bound to a particular Master. Therefore, if at some point in the future, another Master is configured with the same system number, the result is that the DXLink Module could show up on that other Master.

Notes on Specific Telnet Clients

Telnet and terminal clients exhibit different behaviors in some situations. This section states some of the known anomalies.

Windows Client Programs

Anomalies occur when using a Windows® client if you are not typing standard ASCII characters (i.e., using the keypad and the Alt key to enter decimal codes). Most programs will allow you to enter specific decimal codes by holding Alt and using keypad numbers.

Example

For example, hold Alt, hit the keypad 1, then hit keypad 0, then release Alt. The standard line feed code is entered (decimal 10). Windows will perform an ANSI to OEM conversion on some codes entered this way because of the way Windows handles languages and code pages.

The following codes are known to be altered, bu t others may be affected depending on the computer’s setup.

Characters 15, 21, 22, and any characters above 127.

This affects both Windows Telnet and Terminal programs.

Linux Telnet Client

The Linux Telnet client has three anomalies that are known at this time:

A null (\00) character is sent after a carriage return.

If an “Alt 255” is entered, two of the “255” characters are sent (per the Telnet RAFT).

If the code to return to Command mode is entered (Alt 29 which is CTRL+]), the character is not sent, but the Telnet

Command Mode is entered.

Appendix C - Virtual NetLinx Master

Overview Virtual NetLinx Master (Masterless)

A Virtual NetLinx Master can be created using your PC, which allows NetLinx Studio to facilitate direct file transfers to a DXLink Transmitter or Receiver when a Master is not available.

Four basic procedures must be completed for Virtual Master file transfers:

Set the PC to a static IP address (see below).

Create a Virtual Master in NetLinx Studio (see page 100).

Prepare the DXLink Transmitter or Receiver by placing it in Static IP Mode, assigning a device ID, and setting the connection

type to TCP (see page 101).

Transfer the files using a Virtual Master TCP/IP connection (for IRL file transfers, see page 60; for Firmware file transfers,

see page 86).

Setting PC to Static IP Address

IMPORTANT: When you change the PC’s settings to a static IP address, the address must be in the same subnet as the DXLink unit

(the default static IP address for DXLink Transmitters and Receivers is 192.168.1.2).

Important Information for PCs with Multiple Network Access Points

If the PC has more than one point of network access (multiple NIC cards or wireless networking), check to see if one of the connections uses an IP address of 192.168.1.x before proceeding.

To check for mu l t i p l e netwo r ks:

1. Open the PC’s Start menu (at the lower left of the desktop on the Taskbar) and select Run.

2. Enter cmd and click OK.

3. At the prompt, enter ipconfig /all and press the Enter key.

4. Check the IP Addresses under Connection.

Appendix C - Virtual NetLinx Master

If the PC or Laptop is currently using a connection with an IP address of 192.168.1.x, you will need to disconnect the connection.

To disconnect a network connection:

1. Modem: From the Start menu on the desktop taskbar, select Settings \ Network Connections.

Wireless: From the Start menu on the desktop taskbar, select Control Panel \ Network and Internet \ Manage Wireless

Networks.

2. Right-click the network connection and select Disable.

NOTE: The following procedure uses the most current version of Windows available at the time of publication.

To set a PC to Static IP Mode:

1. From the Start menu on the desktop taskbar, select Control Panel / Network Sharing Center.

2. Click “Change adapter settings” (top left).

3. Right-click on Local Area Connection and select Properties. The Local Area Connection Properties dialog box opens.
