Introduction

The SM-nXm-AV-LCD Audio/Video Matrix switch (VEEMUX-A) allows up to 32 audio/video sources (n) to be connected to up to

16 destinations (m). Different destinations can even be connected to the same source. Video resolution up to 1920x1200@85Hz

is supported with no degradation – guaranteed. Stereo audio is supported, as well as volume control and separate audio/video

switching. An LCD on the front panel indicates the current connections. The VEEMUX-A can be controlled by three methods:

Front Panel Keypad, RS-232 interface, or optional Infrared Remote.

Ordering Information

The SM-nXm-AV-LCD Audio/Video Matrix switch (VEEMUX-A) can be ordered in many sizes and with several control options.

The base unit includes a user keypad and an RS232 port to make up a complete system, with an option for an infrared control.

The infrared option is purchased separately, allowing for maximum user satisfaction in each unique configuration.

The VEEMUX-A Audio/Video Matrix switch is built to a specific size ranging from 8 to 32 inputs and 2, 4, 8, 12, or 16 outputs.

Simply order a VEEMUX-A-nXm where the “n” in the part number represents the number of inputs and the “m” in the part number

represents the number of outputs.

SM-nXm-AV-LCD

Replace the “n” with 8,16, or 32

Replace the “m” with 2,4,8,12, or 16

The following list represents the available sizes that can be ordered:

SM-8x2-AV-LCD SM-16x2-AV-LCD SM-32x2-AV-LCD

and hear audio from port 11).

•Video inputs accept any RGBHV, RGBS, or RGsB signal.

•Video outputs are compatible with any RGBHV or RGBS monitor, regardless of input. (RGsB monitor requires

RGsB input)

•Audio inputs accept any standard line level audio (1Vrms or 2.5Vp-p).

•Audio outputs are capable of driving an 8 Ohm speaker load with 200mW of continuous RMS power.

•The Audio output volume of the AV matrix is adjustable for each output port.

Installation

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

disconnecting any cables.

2. For each video source, connect a VEXT-xx-MM cable from the video port of the source to a video input

(VIDEO-1) of the VEEMUX-A (see Fig. 1).

3. Repeat step 2 for remaining video sources.

4. For each audio source, connect a SA-xx-MM cable from the audio source to the port labeled AUDIO IN 1.

Notes:

The audio port on a CPU may be marked "line out", "spkr", or "headphones". If all 3 jacks are available, use

the jack marked "line out".

The "line out" jack is typically lime green and may be marked with this symbol

The "spkr" jack is typically orange, and may be marked with this symbol

The "headphones" jack may be marked with this symbol

5. Repeat step 4 for remaining audio sources, connecting them to any remaining AUDIO IN ports.

Control Options

The VEEMUX-A Audio/Video Matrix Switch has three methods of control: Front Panel Keypad, RS232, or Infrared. Every unit

comes standard with the Front Panel Keypad and RS232 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 unit. No software is involved (see page 14 – Infrared Control). 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 8 – RS232 Control).

Display previous 4 connections

MENU Display the RS-232 menu. (See RS232 control on page 8.)

* Additional functions

Making Connections

The VEEMUX-A allows audio and video connections to be made concurrently or separately. In both situations, the output port

number must always be entered first.

•Connecting audio and video concurrently

When making this connection, any one of the following commands may be used:

1. <OUT>, Single digit output port number, <IN> or <ENTER>, Single digit input port number, <ENTER>.

Ex: <OUT> 3 <IN> 5 <ENTER>

2. Single digit output port number, <ENTER>, Single digit input port number, <ENTER>.

Ex: 3 <ENTER> 5 <ENTER>

3. Double digit output port number, Double digit input port number.

Ex: 03 05

All outputs can be connected to a single input by using <*>:

1. <*>, Single digit input port number, <ENTER>

Ex: <*> 5 <ENTER>

2. <*>, Double digit input port number

Ex: <*> 05

•Connecting audio only

To make an audio connection without changing the current video connection, use any of the following commands:

1. <OUT>, <▼>, <▼>, Single digit output port number, <IN> or <ENTER>, Single digit input port number, <ENTER>.

Ex: <OUT> <▼> <▼> 3 <IN> 5 <ENTER>

2. <OUT>, <▼>, <▼>, Double digit output port number, Double digit input port number.

Ex: <OUT> <▼> <▼> 03 05

All audio outputs can be connected to one audio input by using <*>:

1. <*>, <▼>, <▼>, Single digit input port number, <ENTER>

Ex: <*> <▼> <▼> 5 <ENTER>

2. <*>, <▼>, <▼>, Double digit input port number

Ex: <*> <▼> <▼> 05

•Connecting video only

To make a video connection without changing the current audio connection, use any of the following commands:

1. <OUT>, <▲>, Single digit output port number, <IN> or <ENTER>, Single digit input port number, <ENTER>.

Ex: <OUT> <▲> 3 <IN> 5 <ENTER>

2. <OUT>, <▲>, Double digit output port number, Double digit input port number.

1. <*>, <▲>, Single digit input port number, <ENTER>

Ex: <*> <▲> 5 <ENTER>

2. <*>, <▲>, Double digit input port number

Ex: <*> <▲> 05

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 +6dB (2dB/ press).

Ex 2: <OUT> <▼> 14 <▼> <▼> <ENTER>

This will decrement the volume by -4dB.

•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 10 memory locations available to save connection configurations.

•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>

Serial Menu

The serial menu 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> – 1200

<2> – 2400

<3> – 4800

<4> – 9600

Ex: <MENU> 1 4

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)

Ex: <MENU> 2 03

This will set the address at 03
