NTI VIDMUX VGA Video-Only Switch

RACK-MOUNTING

This NTI switch was designed to be mounted to a rack or to set on a desktop. It includes rackmount ears to make attachment to a
rack easy, and rubber feet to be applied to the bottom of the case if it will instead sit on a flat surface. If this will sit on a flat
surface, simply apply the rubber feet to the bottom of the case in each of the 4 corners.

To Mount to a Rack

1. Attach the ears to the switch using the 6-32x3/16" flat Phillips-head screws (6) provided as shown in the illustration below.
The holes in the ears should line up with pre-threaded holes in the sides of the NTI switch. Tighten the screws securely.

Cable Connections

1. Turn OFF power to video source(s) and monitor(s).

2. Connect the supplied VEXT-3-MM cable between the video port on a video source and th e “VIDEO 1” connector on the
VIDMUX.

3. Connect video cables from additional video sources to the remaining “VIDEO x” ports on the VIDMUX.

FYI: Additional VEXT cables are available from NTI in 1.5,3,6,10,15,25,35,50,75, and 100 foot lengths.

4. Connect VGA monitor to the “MONITOR” connector on the VIDMUX.

5. Connect the IEC power cord to the IEC connector.

RS232 Control

(Applicable to models ending in “-RS” only)

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 11) between the user terminal and the 9 pin DIN female connector on the VIDMUX
labeled "RS232". (See Fig. 3)

Power Up Sequence

1. Power ON the VIDMUX.

2. Power ON the user monitor.

3. Power ON each video source connected.

LOCAL CONTROL

Note: RS232 Control is not available when the Local Control option is present.

The VIDMUX with model number ending in “-L” is equipped with switches for local control over video connectio ns between the
user and the connected video source. With a video source connected to a numbered video port on the rear of the VIDMUX,
simply press the button associated with the video source to view the video from that video source on the user’s monitor. As long
as the VIDMUX is not in Scan Mode (below), the user will remain connected until another button in pressed.

VIDMUX

Scan Mode

Models with Local Control also have the feature Scan Mode. When in Scan Mode the VIDMUX scans to each port with a video
source powered-ON. (The SCAN LED on the front panel will illuminate and remain ON while in Scan Mode.) To enter Scan Mode
press the “Scan” button on the front of the VIDMUX. The video from the source will be visible until the VIDMUX switches to the
next powered-ON video source port (5 seconds). To exit Scan Mode, press the “Scan” button again.

RS232 CONTROL

Note: Local Control is not available when the RS232 Control option is present.

RS232 Connections and Configuration

Models ending in “-RS” include a 9DB female serial connector on the rear of the switch for connection to a terminal or device with
a terminal program. Using a cable wired straight-through (not “null modem” –see specs on page 11), connect a terminal to the
VIDMUX and configure the terminal program. Configure the terminal program and VIDMUX for a b aud rate between 300 and
9600 as instructed below.

Remote Connection

The RS232 Interface is designed to meet the RS232C standard and can be controlled from any CPU or other contro ller with an
RS232 communications port. The pin-out for the 9DB connector on the unit is as follows:

On the 9DB female connector, pins 1 (DCD), 4 (DTR), and 6
(DSR) are shorted and pins 7 (RTS) and 8 (CTS) are shorted.
Therefore, host handshaking is bypassed and TXD and RXD
are the only active signals. A straight-through 9DB serial cable
(not null modem- see specifications on page 11) wil l wo r k
for most CPUs. To daisy chain multiple units, a Matrix Y-1
cable is used (see page 7) for each VIDMUX in the chain.

Baud Rate

The baud rate can be changed either using the RS232 Command Protocol (page 8) or by powering down the unit, changing the 8
position RS232 dip switch on the front of the VIDMUX, and then powering back up. The table below shows how to set the baud
rate. The default positions are 2,3 and 4 ON as shown in gray.)

Note: The baud rate as configured by the dip switches will be the set baud rate each time the VIDMUX is power cycled,
regardless of what the baud rate is changed to via the RS232 Command Protocol.

Unit Address

To allow multiple units to be controlled from a single CPU port, the RS232 control interface is designed to allo w "daisy chaining"
up to 15 units. By setting the appropriate RS232 dip switches, each unit can be given a unique addr ess (1-15). Then the unit will
only respond to commands on the bus if its address is embedded in the command. Use the table below to set the unit address.
The default switch positions are 5 ON, 6 OFF, 7 OFF, and 8 OFF (shown in gray).

Command Protocol

CPU controller commands supported by the unit are defined below. All commands should be terminated with a <CR> (carriage
return). All characters in the command string should be upper case, and all numbers below 10 should have a leading 0 (ex: 1 =

01).

Note: Alternatively, the user may use the Matrix Switcher's Control Program or SerTest to control th e VIDMUX via RS232
(see pages 9 and 10).

Note: The baud rate as changed via RS232 will hold only until the VIDMUX is power cycled. On power-up, th e VIDMUX
will resume the baud rate as configured via the dipswitches on the VIDMUX (see page 6). To make a lasting baud rate
change, adjust the dipswitch positions as indicated in the baud rate chart (page 6).

NTI VIDMUX VGA Video-Only Switch

Autostatus

When Autostatus is enabled, any output-to-input connection change in the VIDMUX will cause an Autostatus message to be sent
via RS232 to the administrator. The format of the message will be "pc SW,OP:IP<CR>"

Example of an Autostatus message:
pc 01,01:04<CR>
which means "At the switch with unit address 01, the output (01) has changed connection to input 04."

Notes: Any message to the administrator will be delayed by any RS232 traffic being received by the switch from the
administrator.
Autostatus must be disabled before using SerTest or the Matrix Switcher's Control Program (below).

By default, Autostatus is disabled and must be manually enabled. Autostatus is also disabled any time the power to the
VIDMUX is interrupted.

Scan Mode

Scan Mode causes an output port to automatically switch from one input port to the next consecutive input port after a specified
period of time (referred to as the dwell time). Port switching will continue indefinitely and no ports will be skipped, whether there
are video sources connected to them or not. If desired, the VIDMUX can be configured to skip the scanning of specific ports by
removing them from the scan list using the RS232 Command Protocol (page 8).

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, then the video to that output will only
change as decided by the administrator.
