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
1.
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.

3. Audio connections can either be digital or analog (stereo). A connector marked "DIGITAL" is provided in each INPUT group
for digital audio cable connection. A terminal block for the connection of a line-level stereo audio cable is located below each
connector group. (See Fig. 1) The VEEMUX-A supports balanced line-level audio signals, as well as unbalanced. Fig. 2 shows
the proper cable connection method for each.

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.

Connect RS232
RS232 control can be achieved using a separate user terminal or CPU with a terminal program.
To make a terminal connection, connect a serial cable (specifications on page 30) between the user terminal and the 9 pin DIN
female connector on the VEEMUX-A labeled "RS232". (See Fig. 3)

If the Telnet Interface (page 14) or Web Interface (page 16) will be used, an Ethernet connection to the Local Area Network (LAN)
must be made using CAT 5 cable with RJ45 connectors wired straight through (pin 1 to pin 1, pin 2 to pin 2, etc). Connect a CAT
5 cable between the connector label "ETHERNET" and the LAN (see Fig. 4).

1. Connect the IEC power cord to the VEEMUX-A and plug the cord into an AC power outlet.
2. Turn ON power to the VEEMUX-A using the switch above the IEC socket.
3. Turn ON power to the video and audio sources, and the video and audio devices connected to the VEEMUX-A, if they are
not already ON.

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)
OUT: 1 2 3 4
V
IN: 1 2 3 4
LCD WILL CYCLE TO DISPLAY A "v" FOR ALL VIDEO INPUTS FIRST, THEN A "a" FOR ALL AUDIO INPUTS.

MENU The RS-232 menu is displayed. This allows the baud rate to be set at 9600, 2400, 1200 or 300 baud and the unit
address to be set to 1 - 15. See RS-232 control later in this chapter.

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
