NTI AUDIO/HD VIDEO MATRIX SWITCH

INTRODUCTION

The VEEMUX SM-8X4-HDA (VEEMUX-A) is a versatile multi-input audio/video matrix switch that independently switches eight sets of incoming YPbPr component video and analog/digital audio signals to any or all of the four outputs. Each input and output has YPbPr component video, L/R analog audio (balanced/unbalanced), and digital audio on coax (S/PDIF).

Video resolution up to 1920x1080@60Hz is supported with no degradation – guaranteed. An LCD on the front panel indicates the current connections. The VEEMUX-A can be controlled by four methods: Front Panel LCD with Keypad, RS232 interface, Ethernet, or optional Infrared Remote. The SM-8X4-HDA is the ideal solution for many applications, such as mission critical command centers, sports facilities and entertainment venues.

Features

• Supports High Definition and Standard Definition YPbPr component video, S-Video or composite video.

• Audio can be unbalanced analog stereo, balanced analog stereo or digital S/PDIF.

• Supports S/PDIF, DTS Digital Surround™, and Dolby Digital™ 5.1 digital signals.

• Supports 480i (interlaced), 480p (progressive), 720i, 720p, 1080i, and 1080p formats.

• Features break-away audio- allowing audio to be switched independent of video.

• Equipped with volume control: -80dB to 10dB, in 1dB steps.

• Control the switch through Ethernet, RS232, front panel buttons or optional IR remote.

Optional Feature

• Infrared Control (see page 25)- to order, add "IR" to the part number (i.e. SM-8X4-HDA-IR)

INSTALLATION

Connect the Sources

Turn OFF power to all video sources (inputs) that will be connected to the VEEMUX-A before connecting or

disconnecting any cables.

2. Connect each video source to the VEEMUX-A using 4CEXT-xx BNC cables. The groups of terminals are labeled INPUT1-8. and colored cables attach to terminals as follows: green (Y), blue (Pb) and red (Pr). If necessary, use BNC to RCA adapters to connect the cables to the video sources (see Fig. 1). If the cables used do not have BNC connectors on them but have RCA connectors instead, use an RCA-to-BNC adapter on each to connect to the VEEMUX-A.

Connect the Devices

1. Connect each of the video display devices to the VEEMUX-A using 3CEXT-xx or 4CEXT-xx cables. The groups of terminals are labeled OUTPUT1-4. Use BNC to RCA adapters (as shown in figure 3) to connect the BNC cables to the devices. Connectors on the VEEMUX-A are labeled green (Y), blue (Pb) and red (Pr) to correspond with the colors on the BNC cables.

2. Connect each digital audio device to a OUTPUT connector labeled "DIGITAL". If the audio device is a stereo type device, connect it an OUTPUT terminal block. Connections to the terminal block should be made as shown in Fig. 2 for devices that are compatible with balanced or unbalanced stereo audio.

Note: Stereo audio devices can not be used to listen to digital audio sources, and digital audio devices can not be used to listen to stereo audio sources.

NTI AUDIO/HD VIDEO MATRIX SWITCH

CONTROL OPTIONS

The VEEMUX-A video matrix switch has four methods of control:

• Front Panel LCD with Keypad

• Directly via an RS232 Interface

• Remotely via Ethernet (web interface)

• Infrared Remote (optional).

Every unit comes standard with the Front Panel LCD with Keypad, RS232, and Ethernet connection built-in. If desired, the Infrared option must be requested at the time of the order. The Infrared option requires the purchase of a separate remote control device (Infrared transmitter) as well as an Infrared receiver to be installed in the VEEMUX-A. No software is involved (see Infrared Control on page 25). With the RS232 option, there are no external devices to be purchased. NTI provides software commands as well as a test program to ensure the RS232 functions properly (see page 10 – RS232 Control).

Front Panel LCD with Keypad Control

The front panel LCD and keypad allow the user to monitor switch status and route any display to any video source on the switch. When the unit is powered up, each monitor is automatically connected to the video source of its equal number (i.e. monitor 1 to source 1, monitor 2 to source 2, monitor 3 to source 3, etc.). Along with the routing of the inputs (video sources) to the outputs (monitors) the keypad and LCD allow the users to configure the RS-232 control interface. The keypad buttons perform the following functions.

ESC Escape back to the main display.

0 – 9 Used to enter numbers. ( # )

OUT The output user number can be entered

(2 digits or 1 digit and ENTER or IN)

NTI AUDIO/HD VIDEO MATRIX SWITCH

Volume Control

The volume level can be adjusted on each output port.

• To increment <▲> or decrement <▼> the volume, use the following command: <OUT>, <▼>, Double digit output port number, <▲> increment or <▼> decrement, <ENTER>

Ex 1: <OUT> <▼> 03 <▲> <▲> <▲> <ENTER>

This will increment the volume by +3dB (1dB/ step).

Ex 2: <OUT> <▼> 14 <▼> <▼> <ENTER>

This will decrement the volume by -2dB.

• To Mute, use the command: <OUT>, <▼>, Double digit output port number, the <0> key, <ENTER>

Ex: <OUT> <▼> 03 0 <ENTER>

This will mute output 3

• To Un-mute, use the instruction: <OUT>, <▼>, Double digit output port number, the <1> key, <ENTER>

Ex: <OUT> <▼> 03 1 <ENTER>

This will un-mute output 3

Memory Functions

There are 100 memory locations(0-99) available to save connection configurations. Location 0 is the power-ON default).

• Saving Connections

To save all current connections, use the following command: <*>, <OUT>, Memory location, <ENTER> Ex: <*> <OUT> 5 <ENTER>

• Restoring Connections

To restore connections from memory, use the following command: <*>, <IN>, Memory location, <ENTER> Ex: <*> <IN> 5 <ENTER>

Note: If the current switch configuration includes assigned Scan Mode dwell time values (pg. 9), to save the current configuration be sure to assign a memory location to it. Otherwise, when the VEEMUX-A is powered OFF, all dwell time values will be erased. Also, saving the configuration as memory location 0 will cause it to be the power-ON default configuration.

Menu Button

The Menu button is used to configure the RS-232 port.

• The baud rate is selected from the “Baud Rate Menu” . To access this menu, use the command: <MENU>, the <1> key

Next, press the keypad number corresponding with the desired baud rate: <1> – 9600 <2> – 4800 <3> – 2400 <4> – 1200

Ex: <MENU> 1 1 This will select 9600 baud

• To set the switch address, use the following instruction: <MENU>, the <2> key, Double digit address (from 01 to 15- the default address is 01)

Ex: <MENU> 2 03

This will set the address at 03

Page 13

NTI AUDIO/HD VIDEO MATRIX SWITCH

Scan Mode

Scan Mode causes output ports (audio and video) to automatically switch from one audio and video input port to the next consecutive audio and video input port after a specified period of time (referred to as the dwell time). Audio and video port switching will continue indefinitely and no ports will be skipped, whether there are audio or video sources connected to them or not. If desired, the VEEMUX-A can be configured to skip the scanning of specific ports using the RS232 Command Protocol (page 10) or Telnet (page 14) .

Dwell time settings can be any value from 0 seconds (000) to 255 seconds. A setting of 000 seconds (the default setting) disables Scan Mode for that output port. If Scan Mode is disabled for a specific port number, then the video or audio to that output port number will only change as decided by the administrator.

Note: While Scan Mode is enabled, audio and video ports of the same number will switch together. Independent control of video and audio ports will be disabled. I.e., when video output 1 switches from input 1 to input 2, audio output 1 will also switch from input 1 to input 2.

To configure Scan Mode from the front panel LCD:

Press MENU, the following lines will be displayed:

1) Set Baud Rate

2) Set Unit Addr

Press MENU again, the following line will be displayed:

3) Set Scan Mode

Press 3 to select that menu item. The following request will be displayed:

Select Port

Select the output to be programmed using the numeric keys, then press ENTER. The display will show the current Dwell Time value for that output and ask for a new value.

Current Time: 16 New Time:

Using the numeric keys, enter a value between 0 and 255 and press ENTER. Leading zeros are allowed (000) but the number should not exceed 3 digits. The Scan Mode dwell setting value 0 will disable Scan Mode for that output port.

Scan Mode dwell time settings can also be configured through the RS232 Command Protocol (page 10), Telnet commands (page

14), or through the Web Interface (page 21).

NOTE: Scan Mode configuration settings can only be saved if they are assigned a memo ry location via the Keypad Control (page 8). Otherwise when the power is cycled to the VEEMUX-A, all Scan Mode settings will be erased.

TIP: If the Scan mode settings are stored as memory location 0, they will be loaded each time the VEEMUX-A is powered ON.

NTI AUDIO/HD VIDEO MATRIX SWITCH

RS232 Control

Remote Connection

The RS232 Interface is designed to control the switch via serial (RS232) daisy chain connection from any host computer or other controller with an RS232 communications port. There is, however, a restriction that must be followed:

A program must be used that will send an entire command line all at on ce, not character by character. (The

HyperTerminal program in WINDOWS cannot be used, as it sends each character one at a time.)

The pin outs for the DB-9 connector on the unit are as follows:

RS232 Connector (DB-9 FEMALE)

PIN SIGNAL FUNCTION

None no connection

2 TXD Transmit Data (RXD at host) 3 RXD Receive Data (TXD at host) 4 DSR Data Set Ready 5 GND Signal Ground 6 DTR Data Terminal Ready 7 CTS Clear to Send 8 RTS Request to Send 9

none no connection

On the DB-9 female connector, pins 4 (DSR) and 6 (DTR) are shorted and pins 7 (CTS) and 8 (RTS) are shorted. Therefore, host handshaking is bypassed and TXD and RXD are the only active signals. A straight through DB-9 cable (not null modem) will work for most CPUs. To daisy chain multiple units, use NTI Matrix-Y-1 "Y" cables, except for the last unit connected. (see Fig 6). For a pinout of the Matrix-Y-1 cable, see page 31. For straight through cable pinouts applicable to various terminal types, see page

30.

Baud Rate

The unit powers up with a default baud rate of 9600 and a fixed data protocol of 8 data bits, no parity and 1 stop bit. The baud rate can be changed by pressing the MENU button on the front panel keypad. Then select 1 for SET BAUD RATE and select the desired baud rate of 9600, 2400, 1200 or 300. A data protocol of 8 data bits, no parity, and 1 stop bit is used for communications.

Unit Address

To allow multiple units to be controlled from a single CPU port, the RS232 control interface is designed to allow "daisy chaining" up to 15 units using the NTI Matrix-Y-1 "Y" cables (sold separately- pin out is on page 28). By setting the appropriate unit address with the keypad, each unit can be given a unique address (1-15). Then the unit will only respond to commands on the bus if its address is embedded in the command. To set the unit address select MENU on the front panel keypad. Then select 2 for SET UNIT ADDRESS and then type the address number (1-15) and (ENTER).

Command Protocol

CPU controller commands supported by the unit are defined below. All commands should be terminated with a <CR> (carriage return). When a command is sent, the entire string is echoed back to the CPU along with a response from the addressed unit as shown in the command definitions. All characters should be upper case, and all numbers below 10 should have a leading 0 (ex: 1 = 01).

NOTE: For units with one output or user port, use 01 for the output select.

(square image with circle in the center) that intersects the input and output columns. A black dot will be placed in the circle to indicate the selection. Then

press the Submit button. The display will be

reloaded with the selections changed to orange to indicate they are now active. Multiple connections can be changed simultaneously.

To quickly clear the selected radio buttons press the Clear Changes button. This will only work if the Submit button has not already been pressed with the

selections made.

To quickly connect all outputs to a single input,

choose the desired input from the "Set all Outputs to

Input" drop-down list and press the Submit button.

Figure 10- Web interface Video Switch page

Note: If radio buttons are selected in addition to using the "Set all Outputs to Input" option, the selections made by the "Set all Outputs to Input" will take precedence when the Submit button is pressed. Selections that conflict with it will be ignored.

To save a configuraton, from the Stored Configurations user interface, use the drop-down list to select the desired slot (numbers 0-99) to save the active configuration into and press the Save button.

Note: This will save the currently active configuration on the VEEMUX-A. If changes have been made in the web interface without first pressing the Submit button, those changes will not yet be part of the active configuration.

Note: If changes to the active configuration have been made by another user prior to saving the current connection selections, the changes made by the other user will be saved as the configuration.

The webpage configuration that loads after a Save is the configuration that was actually saved.

Page 22

How To Use The IRT

The IRT-64X32 enables the user to control the connections of up to 32 input ports and 16 output ports on up to four (4) separate NTI video matrix switches. When any key is pressed, the IRT will power ON. A number key should always be pressed first unless a change to the configuration is desired (see "Set Configuration" on page 28). When a number key is pressed the LCD will display that number blinking. What to press next depends on what action is desired;

• change the switch to be controlled

• change the output port

• change the input port

Note: The user must always change or confirm the output port first and the input po rt seco n d

If the "SYS", "IN" or "OUT" key is pressed first, the LCD will display the current switch followed by the decimal point and an error signal "EE". The error signal will display because there is no number to be displayed. A number key must always be pressed before a "SYS", "IN" or "OUT" key is pressed.

Exception: The "SYS" key is pressed first when setting the configuration. (See page 28)

Power ON with SYS, IN or OUT keys Power ON with "2" key

Change the Switch

Press the number of the switch to be controlled. The number selected will be blinking in the last digit.

FYI: If the user realizes that an invalid number has been introduced before pressing either the "SYS", "IN", or "OUT" buttons, a correction can be made by pressing the correct number. If the correct nu mb er is a sin gle digit, it must be preceded by a "0" to make the correction.

Press the "SYS" key. The blinking number will become blank and the switch number will update.

Note: If the number entered is larger than 4, when the "SYS" key is pressed the LCD will display the current switch and the error signal "EE".

Page 31

NTI AUDIO/HD VIDEO MATRIX SWITCH

Change Output Port

Press the desired port number. If there is no change in the desired output port, the output port must still be selected. As the digits are selected, the last number entered will blink. The LCD will also display the current switch number followed by the decimal point.

With the desired port number selected, point the IRT at the switch/receiver and press the "OUT" button to transmit the selection and make the change. The blinking number in the LCD will stop blinking. An LED on the receiver will illuminate.

FYI: If the switch did not receive the data the LED will not illuminate. The user can re-send the same data by pressing the "OUT" button again. The LED at the receiver will illuminate to indicate a completed transmission from the IRT..

Note: If the number introduced is larger than the maximum number of ou tputs the IRT is configured for, then once the "OUT" key is pressed the LCD will display the current switch and the error signal "EE".

Change Input Port

Press the desired port number. As the digits are selected, the last number entered will blink. The LCD will also display the current switch number followed by the decimal point.

With the desired port number selected, point the IRT at the switch/receiver and press the "IN" button to transmit the selection and make the change. The blinking number in the LCD will stop blinking. The LED at the receiver will go OFF.

FYI: If the switch did not receive the data the LED will not go OFF. The user can re-send the same data by pressing the "IN" button again. The illuminated LED on the receiver will go OFF when the received data is complete.

Note: If the number introduced is larger than the maximum number of inpu t s th at the IRT is configured to control, then once the "IN" key is pressed the LCD will display the current switch and th e error signal "EE".

Page 32

NTI AUDIO/HD VIDEO MATRIX SWITCH

Set Configuration

The IRT-64x32 factory default setting is 32 inputs and 16 outputs. When the batteries are changed the setting will return to the default value. At the default setting the IRT has the ability control any matrix switch with up to 32 inputs and 16 outputs without changing the configuration. However, when controlling smaller switches without changing the configuration it is up to the user to press valid number(s). To avoid confusion, it is recommended to configure the IRT to communicate with the largest switch to be controlled.

To change the maximum number of inputs or outputs:

1. From power-down state (blank LCD) press and hold the "SYS" button for at least 3 seconds. The LCD will first display an

error message but after 3 seconds the letter "c" will display:

2. Enter the number of inputs or outputs. As the digits are entered, they will be displayed and the last one entered will blink.

Note: Only the inputs OR the outputs may be conf igured each time the configuration function is used. To perform another configuration operation the user must start again at "Set Configuration" step 1.

3. Accept the choice by pressing the "IN" button for setting inputs, or the "OUT" button for setting the outputs. The LCD will not

blink anymore and will display “i” (for inputs) or "o" (for outputs) and the number.

Notes:

- The maximum number of inputs and outputs that can be entered is 32 and 16 respectively. If the user introduces a

number larger, the display will show an error signal ("c.EE") and the maximum number will remain at the last valid value configured.

- If more than one switch is being controlled, the IRT should be configured for the largest switch. It is up to the user

to introduce valid numbers to the smaller switches when making selections.

NTI AUDIO/HD VIDEO MATRIX SWITCH

Battery Replacement

The IRT has a low-battery indicator to let the user know when it is time to change the batteries. The right-hand decimal point in the LCD display will illuminate (see illustration below). This will stay illuminated while the IRT is in use until the batteries are changed or the battery charge is too low for the IRT to operate.

To Change The Batteries:

1. Remove slide cover on rear of unit.

2. Remove old batteries carefully.

3. Insert (2) new “AA” cell batteries.

4. Replace slide cover on unit.

5. Reset the configuration if a range other than the default setting is desired.
