nal equipment to the CardFrame.

CardFrame can be powered via the Master Card (default) or by an external power supply connected to the CardFrame's PWR connector. If a power supply is connected to the PWR connector, the CardFrame power automatically switches to the connected power supply. In that case, the Control Cards and CardFrame are independently powered.

A simple rule to follow is if the CardFrame contains eight or more Control Cards, use two 12 VDC power supplies.

8-position DIP switch address range is 1-3072.

Mounting Master/Hub Cards in an NXF CardFrame

NetLinx Master and Hub Cards can be installed in the NXF CardFrame. The card mounts in a

horizontal position, through the master card slot on the rear panel of the NXF enclosure. To install a

Master or Hub Card in an NXF:

1. Discharge the static electricity from your body by touching a grounded metal object.

2. Unplug all the connectors from the NXF.

3. Remove the two screws holding the front plate on the Master Card, and remove the front plate.

4. Align the edges of the card with the guide slots inside the Master Card slot on the NXF.

5. Slide the card about halfway into the slot.

6. Inside the Master Card slot on the NXF, locate the 6-pin control cable connector.

7. Plug the connector from the NXF into the 6-pin terminal on the Master Card. This connector is

keyed to ensure correct orientation.

8. Once the control cable is connected, gently slide the card all the way in until you feel the rear

edge of the card lightly snap into place.

9. Re-apply power and other connections as necessary.

NXF CardFrame and NetModules

Setting the CardFrame's starting address

The 8-position CardFrame Number DIP switch, located on the rear of the CardFrame (FIG. 1 on

page 1), sets the starting address (the device number in the D:P:S specification) for the Control

Cards installed in the CardFrame. The address range is 12-3060. The formula for setting the

starting address is:

(DIP switch address x 12) + Card slot Number (1-12) = Card address

For example:

 For DIP switch setting, 00010101: (0 + 0 + 0 + 0 + 96 + 0 + 384 + 1536) + SLOT #(ex:1)

= 2017.

 A card in slot number 7 would be device address 2023.

1. Set the CardFrame Number DIP switch based on the information listed in the table below.

Position 12345678

Val ue 12 24 48 96 192 384 768 1536

2. Cycle power for approximately 5 seconds, so the system can read the new device number

settings.

Factory default DIP switch value = 0 (zero) (All DIP switches are in the OFF position).

Device:Port:System (D:P:S)

A device is any hardware component that can be connected to an AXlink or ICSNet bus. Each

device must be assigned a unique number to locate that device on the bus. The NetLinx

programming language allows numbers in the range 0-32,767. Device 0 refers to the local Master;

numbers greater than 32,767 are reserved.

NetLinx requires a Device:Port:System (D:P:S) specification. This D:P:S triplet can be expressed

as a series of constants, variables separated by colons, or a DEV structure. For example:

STRUCTURE DEV

{

INTEGER Number // Device number

INTEGER Port // Port on device

INTEGER System // System the device belongs to

}

The D:P:S notation is used to explicitly represent a device number, port and system. For example,

128:1:0 represents the first port on device 128 on this system. If the system and Port specifications

are omitted, (e.g. 128), system 0 (indicating this system) and port 1 (the first port) is assumed.

Here's the syntax:

CardFrame and press until you feel the Card seat in the backplane connector.

3. Put the magnetic faceplate back on the CardFrame. Secure with mounting screws (if

necessary).

Preparing/connecting captive wires

1. Strip 0.25 inch of wire insulation off all wires.

2. Insert each wire into the appropriate opening on the connector according to the wiring

diagrams and connector types described in this section.

3. Tighten the screws to secure the wires in the connector. Do not tighten the screws excessively;

doing so may strip the threads and damage the connector.

Using the ID button

The ID Button on the rear panel of the NetModules (see FIG. 2) is used in conjunction with the

NetLinx Studio software program to allow you to assign new Device and System numbers for the

Module.

1. Using NetLinx Studio, place the system in Identity (ID) Mode. ID Mode means the entire

system is put on hold while it waits for an event from any NetLinx device in the named system

(for example, pushing the ID button on a Module). The device generating the first event is the

identified device.

2. Press the ID Mode button to generate an event from the Module and allow you to assign new

Device and System numbers in NetLinx Studio.

NXC-I/O10 Input/Output Control Card

The NXC-I/O10 Input/Output Control Card (FG2021) provides 10 Input/Output channels and LED

feedback. It acts as a logic-level input and responds to switch closures or voltage level (high/ low)

changes. The Switch (SW) and Voltage (VO) modes are set with on-board jumpers. FIG. 4 shows

the I/O10 card.

The I/Os on this card are not dry closure; they are electronic switches that float at 5V when Off. Therefore, they should not be expected to work in situations that require true dry contact (or dry closure).

The I/Os do work with AMX PC1, PC2, UPC20 and UPC20+.

NXC-I/O10 Input/Output Control Card

Setting the Switch/Voltage Mode Jumpers

The NXC-I/O10 responds to switch closures or voltage-level (high/low) changes. Compatible I/O

devices include the Power Control Sensor (PCS), tape transports and limit switches. The inputs are

set for SW mode (closure) or VO mode as described below.

SW (switch) Mode setting (default)

(Jumper pins 2 and 3)

VO (voltage) Mode setting

(Jumper pins 1 and 2)

Senses switch or relay contact closures or provides a logic-level output. The 3-pin jumpers for each input should be set to SW before wiring inputs to the Card. An "On" condition is triggered by contact closures or a logic low of 0 to 1.5 VDC. An "Off" condition is triggered by a logic high of 2.5 to 5 VDC; set the associated I/O to switch mode. When used for an output, each I/O port acts as a switch to ground (GND), and is rated at 200 mA @ 12 VDC.

Senses high- and low-voltage states commonly from AC or DC signals. This mode provides opto-isolation. The 3-pin jumpers for each input should be set to VO (voltage mode) before wiring inputs to the Card. An "On" condition is triggered by DC levels from 2.5 to 28 VDC (+ or -), or AC levels from 2.5 to 24 VAC. An "Off" condition is triggered by DC levels from 0 to 1.5 VDC (+ or -) or AC levels from 0 to 1.5 VAC.

In switch mode, the A terminals are connected to the NetLinx Controller's ground. Sources that require isolation from the Controller's ground should use voltage mode, and provide switched DC power for sensing as required.

Setting the Voltage Clamp Jumper (+12V or Open)

Set the V- Clamp jumper (J31) to +12 V (default) to clamp any voltage connected to I/O ports 1-10

to 12 V. Set to Open for connections that will draw more than 12 V. Remember, the +12 V and

OPEN settings are only enabled when the I/O ports are set to SW mode. The V-Clamp jumper

settings are described below.

+12 V mode setting (default) Use the default setting for all loads that require less than 12 V.

Open mode setting When this jumper is set to Open, and an I/O port is used as an

output, the I/O port is rated at 85 mA @ 28 VDC.

When this jumper is Open, it is the technician's responsibility to clamp the external source relay

anytime the voltage exceeds 12 V. The source relay should always be clamped if the voltage

exceeds 12 V. Contact the relay manufacturer to determine the size of the diode in the source relay.

CTOF

Set the duration of the Off time (no signal) between IR pulses for channel and IR function transmissions.

CTON

Set the total time of IR pulses transmitted and is stored in non-volatile memory.

All channels below 100 are transmitted as two digits. If the IR code for ENTER (function #21) is loaded, an Enter will follow the number. If the channel is greater than or equal to (>=) 100, then IR function 127 or 20 (whichever exists) is generated for the one hundred digit. Uses 'CTON' and 'CTOF' times for pulse times.

Syntax:

SEND_COMMAND <DEV>,"'CH',<Number>"

Var iabl e:

channel number = 0 - 199.

Example:

SEND_COMMAND IR_1,"'CH',18"

The NXC-IRS4 performs the following:

• Transmits IR signals for 1 (IR code 11). The transmit time is set with the CTON command.

• Waits until the time set with the CTOF command elapses.

• Transmits IR signals for 8 (IR code 18).

• Waits for the time set with the CTOF command elapses. If the IR code for Enter (IR code 21) is programmed, the IRS4 performs the following steps.

• Transmits IR signals for Enter (IR code 21).

Waits for the time set with the CTOF command elapses.

You can set the Pulse and Wait times with the 'CTON' and 'CTOF' commands.

SEND_COMMAND IR_1,"'POD"

Disables the 'PON' and 'POF' command settings on the IR_1 device.

If at any time the IR sensor input reads that the device is ON (such as if someone turned it on manually at the front panel), IR function 28 (if available) or IR function 9 is automatically generated in an attempt to turn the device back OFF. If three attempts fail, the IR port will continue executing commands in the buffer.

If there are no commands in the buffer, the IR port will continue executing commands in the buffer and trying to turn the device OFF until a 'PON' or 'POD' command is received. If the IR port fails to turn the device OFF, a PUSH and RELEASE is made on channel 254 to indicate a power failure error. You can only use the 'PON' and 'POF' commands when an IR device has a linked I/O channel. Channel 255 changes are disabled after receipt of this command.

Programming Information

These NetLinx Send_Commands control the NXC-VAI4:

NXC-VAI4 Send_Commands

Command Description

AD MODE

Sets the format for data reporting to either 8 or 10 significant bits (16 bit format with 10 significant bits).

DEFAULT

Sets all card settings (except for calibration) back to

original factory settings.

DEFAULT ALL

Sets all card settings back to original factory settings.

Even though the output is specified in the command, the format change really applies to the corresponding input. Input level changes and commanded positions are in this format. The reporting of the output levels is unaffected. The default format is 8 bits.

Syntax:

SEND_COMMAND <DEV>,'AD MODE <OUTPUT> 8|10'

Var iabl e:

OUTPUT: Any Output ('1', '2, '3', 4')

Examples:

SEND_COMMAND <DEV>,'AD MODE 2 8'

Sets the reporting format for Input 2 to 8 bits. (0-255)

SEND_COMMAND <DEV>,'AD MODE 1 10'

Sets the input reporting format for Input 1 to 10 significant bits (0 - 65535)

Syntax:

SEND_COMMAND <DEV>,'DEFAULT'

Syntax:

SEND_COMMAND <DEV>,'DEFAULT ALL'

NXF CardFrame, NetLinx Control Cards, and NetModules

NXC-VAI4 Send_Commands (Cont.)

Command Description

GAS

Sets the slowdown distance and slowdown speed.

Sets the maximum allowable deviation of final servo position when executing the GL command.

This command puts the card in servo (positional) control mode.

When these variables have been set, and a GL command is in progress, the speed output on Output <x> will be reduced to that specified when the position as read on Output <x+4> is within the distance specified away from the target position.

Syntax:

SEND_COMMAND <DEV>,'G<OUTPUT>A<DISTANCE>S<SPEED>'

Var iabl es:

OUTPUT: Any Output '1', '2', '3', or '4'

DISTANCE: 0-127

SPEED: 0-127

Example:

SEND_COMMAND <DEV>,'G1A127S127'

Sets Output 1 slowdown distance to 127 (max) at full speed.

The level of the specified input or output will only be reported when a change greater than this deviation occurs.

Deviation 0 is most accurate, but can have some oscillation, so the default is 2, i.e. the position as read at corresponding input I/O <x+4> can be within +/-2 from the specified position.

Syntax:

SEND_COMMAND <DEV>,'G<I/O>D<DEVIATION>'

Var iabl es:

I/O: Any input or output ('1', '2', '3', '4', '5', '6', '7'. '8')

DEVIATION: Number between 0 and 127 (default = 2)

Example:

SEND_COMMAND <DEV>,'G1D10'

Sets I/O 1 servo output to 10.

The range of the position is 0-255 (if AD MODE is set to '8'), or 0-65535 (if AD MODE is set to '10'). See AD MODE earlier in this section for details.

Position 0 is the low end of the potentiometer (lowest voltage); position 255 (or 65535) is the high end of the potentiometer (highest voltage) with 128 (or

32768) as the middle of the range.

Syntax:

SEND_COMMAND <DEV>,'G<OUTPUT>L<POSITION>'

Var iabl es:

I/O: Any Output ('1', '2, '3', 4')

POSITION: Number between 0-255 or 0-65535 (depends on AD MODE)

Example (Assuming the current position is 0):

SEND_COMMAND <DEV>,'G1L255'

Sets Output 1 to "CURRENT OUTPUT 1 SPEED" (positive) and waits until Input 1 reads within "OUTPUT 1 MAXIMUM DEVIATION" of 255 and then resets the output to zero speed. The speed output may have a more complex profile than as set by the "GAS" command.

Sets the shape of the Output <x> voltage ramps.

The change of speed takes place immediately even if a positional change operation is currently in progress. The voltage output for speed 0 (i.e. when no motion is desired) is at the mid-point between the Min and Max output voltages. The positive speed 127 is the max and negative speed 127 is the min. Other speeds are scaled proportionately.

Syntax:

SEND_COMMAND <DEV>,'G<OUTPUT>S<SPEED>'

Var iabl e:

I/O: Any Output ('1', '2, '3', 4')

B|U: Bipolar or Unipolar (has no meaning for reference selection 'N')

Unipolar mode sets the voltage range to between 0V and +reference voltage.

Bipolar mode sets the output voltage range to between -reference voltage and +reference voltage.

Examples:

SEND_COMMAND <DEV>,'P1EN'

Sets Output 1 to use no reference (MIN/MAX limits are used instead.).

NXC-VOL4 Volume Control Card

NXC-VOL4 Connections/Wiring

The NXC-VOL4 card contains four audio volume control channels. Each line-level channel is

isolated from system ground and can be configured for balanced or unbalanced line operation. It

supports programmable audio levels, audio mute, variable ramp speeds, and preset levels. Each

audio channel's input to output gain ratio is adjustable via the on-board jumpers shown in FIG. 8 on

page 41.

 Unity (jumper not installed)

 Gain (-10 dB Input level/+4 dB Output level setting on pins 1 and 2)

 Attenuate (+4 dB Input level/-10 dB Output level setting on pins 3 and 4)

NXC-VOL4 Channel Assignments

The NXC- VOL4 channel assignments are listed in the following table. This card has 2 ports with 2

audio "channels" in each port. The two audio "channels", which can be used as right and left,

should not be confused with the channel assignments, which are sent to and from the card.

NXC-VOL4 Channel Assignments (per port)

Port 1

Channel:

1 1 While channel is on, ramps the volume on audio channels 1 and 2 up (increase).

2 2 While channel is on, ramps the volume on audio channels 1 and 2 down (decrease).

3 3 While channel is on, the volume on audio channels 1 and 2 are muted (lowest

4 4 While channel is on, ramps the volume on audio channel 1 up (increase).

5 5 While channel is on, ramps the volume on audio channel 1 down (decrease).

6 6 While channel is on, the volume on audio channel 1 is muted (lowest volume); when

7 7 While channel is on, ramps the volume for audio channel 2 up (increase).

8 8 While channel is on, ramps the volume for audio channel 2 down (decrease).

9 9 While channel is on, volume for audio channel 2 is muted (lowest volume); when

volume); when channel is off, the volume levels are restored to their previous levels.

channel is off, the volume level is restored.

Ramping a volume channel while the mute channel is on will not automatically turn off the mute

channel but the ramping will still occur; the volume change will be noticed when the mute channel

is turned off. For setting ramp rates and presets, refer to the Programming Information section on

page 45.

NXC-VOL4 Volume Control Card

NXC-VOL4 Levels

Volume (audio) channels 1 and 2 use levels 1 and 2 respectively. For reading current volume levels

and displaying bargraphs see CREATE_LEVEL and SEND_LEVEL . The two levels associated

with each port of the NXC-VOL4 Control Card are listed in the table below:

NXC-VOL4 Levels

Level Description Level Description

1 Output #1 1 Output #3

2 Output #2 2 Output #4

CREATE_LEVEL

This keyword creates an association between a specified level of a device and a variable that will

contain the value of the level. This can only appear in the

CREATE_LEVEL DEV, Level, Value

Parameters:

 DEV: The device from which to read the level.

Port 1 Port 2

DEFINE_START section of the program.

 Level: The level of the device to read.

 Value: Variable in which to store the level value.

 DevLev: A DEVLEV structure.

 Value: Variable in which to store the level value CREATE_LEVEL DevLev, Value.

During execution of the program, NetLinx continuously updates the variable to match the level that

it represents.

SEND_LEVEL

This keyword sends a value to a specific level on a NetLinx device/port. The syntax follows any one

of the four following examples:

SEND_LEVEL DEV, Level, Value

SEND_LEVEL DEV[ ], Level, Value

SEND_LEVEL DEVLEV, Value

SEND_LEVEL DEVLEV[ ], Value

Parameters:

 DEV: Device containing the specified level

 Level: Number of the level to receive the new value

 Value: New level value

 DEV[ ]: Device array (each device contains the specified level)

 DEVLEV: Device-level to receive the new value

 DL[ ]: Device-level array (each will receive the new value)

Programming Information

These NetLinx Send_Commands control the NXC-VOL4.

NXC-VOL4 Send_Commands

Command Description

Ramps specified (audio) channel(s) from current level to a specified preset level or percentage at the current rate or optionally in a specified amount of time.

Sets the ramp rate of the specified channel(s) where Time is the time to ramp the full range both down to up and up to down or optionally just down to up or just up to down.

Syntax:

SEND_COMMAND <DEV>,'P<Output Channel>L<Level>[T<Time>]'

Var iabl es:

Output Channel: Target audio channel number (0-2). Output channel 0 means both channels 1 and 2.

Level: Target level (0-255 or 0-100%). Level 0 is lowest volume (same as mute) and 255 (or 100%) is maximum volume.

Time: Specifies the amount of time (in .10-second increments) that it takes to ramp the specified audio channel to the specified level.

Example:

SEND_COMMAND MYDEVICE,'P0L50%'

Ramps both audio channels on MYDEVICE to 50% volume at the current ramp rate.

If Time is set to 50, it takes 5 seconds to ramp through the full range of 0 to 255 (0-100%). It would take 2.5 seconds to ramp through half of the range and so on.

Syntax:

SEND_COMMAND <DEV>,'P<Output Channel>R<Time>[U|D]'

Var iabl es:

• Output Channel: Target channel number (0-2). Output channel 0 means both channels 1 and 2.

• Time: Specifies the amount of time (in .10-second increments) that it would take to ramp the full range of 0-100% (down to up and up to down or optionally just down to up or just up to down).

• U|D: Ramps the specified channel(s) from down to up (U) or from up to down (D).

Example:

SEND_COMMAND MYDEVICE,'P0R50''

Sets ramp rate of audio channels 1 and 2 to five seconds full range from down to up and up to down.
