About the MPS Series
The Extron MPS 112 and MPS 112CS are media presentation switchers featuring
three A/V switchers and a program audio switcher with microphone pre-amplifier
and mute controls in one product. The A/V switchers include a four input, one
output VGA/audio switcher, a four input, one output S-video/audio switcher, and
a four input, one output composite video/audio switcher. The MPS 112 and
MPS 112CS accept microphone input and will mix the microphone signal with the
main audio in “talk-over” mode. Both models have an RS-232 control port. The
MPS 112CS also features switchable 48 V phantom power for the microphone.
The MPS Series is a one box solution for small presentation systems.

The MPS 112 and MPS 112CS are housed in 1U high, 17.4" wide metal enclosures
that are rack- or desk-mountable. The appropriate rack/desk mounting kit
(#70-077-03) is included with the switchers. The switchers may also be surface-
mounted under a table, desk, or podium, or on a wall, using an optional Extron 1U
enclosure under-desk mounting kit (#70-222-01).
Rack mounting
Rack mount the switcher as follows:
1. Attach the supplied rack mounting brackets to the switcher with the eight
provided #8 machine screws (figure 2-1).
2. Insert the switcher into the rack, align the holes in the mounting bracket with
those of the rack.
3. Secure the switcher to the rack using the supplied machine screws.
Table or wall mounting
The table/wall mounting brackets extend approximately 1/4" (6.4 mm) above the
top surface of the switcher enclosure. This design allows for an air space between
the enclosure and the surface to which it is mounted. Table or wall mount the
switcher as follows:
1. Attach the table/wall mounting brackets to the switcher with the eight
provided #8 machine screws (figure 2-1).
2. Hold the switcher with the attached brackets against the underside of the
table or other furniture, or against the wall. Mark the location of the screw
holes of the bracket on the mounting surface.
3. Drill 3/32" (2 mm) diameter pilot holes, 1/4" (6.4 mm) deep in the mounting
surface at the marked screw locations.
4. Insert #8 wood screws into the four pilot holes. Tighten each screw into the
mounting surface until just less than 1/4" of the screw’s head protrudes.

Remote connection
The cable used to connect the RS-232/Remote port to a computer or control
system may need to be modified by removing pins or cutting wires. If
unneeded pins are connected, the switcher may hang up.
For RS-232 control, use a control cable with only pins 2, 3, and 5 connected.
Otherwise, either cut the wires to the other pins in hard-shelled connectors or
remove the unneeded pins from molded plugs. See chapter 5, Programmer’s Guide,
for definitions of the SIS commands and details on how to install and use the
control software.
The RS-232 connector is a 9-pin D female with the following pin designations:
Pin RS-232 function Description
1 – No connection
2 Tx Transmit data
3 Rx Receive data
4 – No connection
5 Gnd Signal ground
6, 7 – No connection
8, 9 – No connection
The protocol is as follows:
• 9600 baud
• 8-bit data
• 1 stop bit
• no parity
• no flow control.

Front Panel Operation
Figure 3-2 — MPS switcher front panel
The functions of the front panel controls are described in the following sections.
Input selection in Single Switcher mode
In Single Switcher mode the switcher emulates one switcher with 12 inputs. In this
mode, when one of the inputs is selected, the input is routed to the outputs (video
and audio) for that group and the audio is sent to the program audio output as well.
All of the other outputs are muted.
When you select and press an input button in Single Switcher mode, the green LED
indicator to the right of the button lights steadily. All of the other LEDs will be off.
To select a different input, press a different input button.
The Extron IR 102 Universal Handheld Remote Control can be used with an
MPS 112 switcher only when the switcher is in Single Switcher mode.
Input selection in Separate Switcher mode
There are three input selection groups on the front panel: VGA/Audio, S-video/
Audio, and Video/Audio. These groups correspond to the three independent A/V
switchers (in Separate Switcher mode) available in the MPS 112.
Each of the input selection groups has four numbered input selection buttons
(1 – 4), which allow you to choose from among the four separate input sources in
that group that the switcher can output.
All outputs of the three groups are active, but the audio from only one group is
routed to the program audio output. That group (input) is indicated by a flashing
LED, while the other two groups are indicated by solid LEDs. See the Program
Audio section for more details.
