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 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. Throughout this manual both models of this switcher are referred to as “MPS” or

“MPS 112” if the instructions are not model-specific.

UL rack mounting requirements

The following Underwriters Laboratories (UL) requirements pertain to the safe installation of the MPS in a rack.

1. Elevated operating ambient temperature — If installed in a closed or multi-

unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient temperature. Therefore, install the device in an environment compatible with the maximum ambient temperature (Tma = +122 °F, +50 °C) specified by Extron.

2. Reduced air flow — Install the equipment in a rack so that the amount of air

flow required for safe operation of the equipment is not compromised.

3. Mechanical loading — Mount the equipment in the rack so that a hazardous

condition is not achieved due to uneven mechanical loading.

4. Circuit overloading — Connect the equipment to the supply circuit and

consider the effect that circuit overloading might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.

MPS Series • Installation

5. Reliable earthing (grounding) — Maintain reliable grounding of rack-

mounted equipment. Pay particular attention to supply connections other than direct connections to the branch circuit (e.g. use of power strips).

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.

5. Align the mounting screws with the slots in the brackets and place the

switcher against the surface, with the screws through the bracket slots.

6. Slide the switcher slightly forward or back, then tighten all four screws to

secure the switcher in place.

Through-desk mounting

Mount the switcher through a desk or podium as follows:

1. Attach the supplied mounting brackets to the switcher with the machine

screws provided (figure 2-1).

2. Cut the proper sized hole in the mounting surface.

3. Hold the switcher with the attached brackets against the underside of the

table or other furniture. Mark the location of the screw holes of the bracket on the mounting surface.

4. Drill 3/32" (2 mm) diameter pilot holes, 1/4" (6.3 mm) deep in the mounting

surface at the marked screw locations.

5. Insert four #8 wood screws through the bracket and into the four pilot holes.

Tighten all four screws to secure the switcher in place.

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 turn 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.

The MPS 112 must be in Single Switcher mode if it is to be slaved to an Extron MLC (Medialink™ Controller).

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 through 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 in this chapter for more details.

The MPS switchers accept Simple Instruction Set (SIS™) commands through the RS-232 port. SIS commands consist of one or more characters per command field. They do not require any special characters to begin or end the command character sequence. Each response to an SIS command ends with a carriage return and a line feed (CR/LF = ), which signals the end of the response character string. A string is one or more characters.

MPS switcher-initiated messages

When a local event occurs, such as a front panel operation, the MPS switcher responds by sending a message to the host. The MPS -initiated messages are listed below (underlined).

Boot-up messages

The copyright message is initiated by the MPS switcher when it is first powered on. Vx.xx is the firmware version number.

Status change messages

The switcher issues status change messages as a result of front panel operations (actual or software-simulated). The status change messages are the same as the switcher’s responses to certain commands. See the last column of the table on pages 5-4 through 5-6.

MPS switcher error responses

When the MPS switcher receives an SIS command and determines that it is valid, it performs the command and sends a response to the host device. If the switcher is unable to perform the command because the command is invalid or contains invalid parameters, it returns an error response to the host. The error response codes are as follows:

E01

— Invalid input channel number (too large)

E10

— Invalid command — Invalid value (out of range)

E13

Command/Response Table

The command/response table is shown on the following pages. Lower case characters are acceptable in the command field only where indicated. Symbols are used throughout the table to represent variables in the command/response fields. Symbol definitions are shown below, and an ASCII-to-hexadecimal (HEX) conversion table is shown in figure 5-1. Command and response examples are shown throughout the command/response table.

In Separate Switcher mode this command has the additional function of switching audio inputs to the program output when it is entered more than once.

In Separate Switcher mode, selected audio input from one of the three input groups can be routed to the program audio output. This selected input and group is indicated by a flashing input LED. The LEDs of the two remaining, unselected groups (inputs) are steadily lit.

To route a different audio input within the same input group to the program audio output, enter the command

X1*X2

!. The new input’s LED flashes. To route an audio input from a different group to the program audio, enter the command once if the input is already active and its LED is steadily lit, or enter it twice if the input is not active and its LED is off. The LED for the new input within the new group flashes.

Uploading firmware to the MPS via an SIS command

There are two ways to upload firmware to the switcher:

• Use the MPS Control Program

• Use SIS commands entered via a communication utility such as HyperTerminal.

Extron recommends that you use the MPS control Program to upload firmware (See Uploading Firmware Updates on page 4-3) and reserve this SIS procedure for correcting firmware that has been corrupted and is unable to respond to the MPS Control Program.

To load firmware using SIS commands, follow this procedure:

1. Obtain the new, correct firmware file. a. Visit the Extron Web site, www.extron.com, and locate and select the

product page for the MPS 112 or MPS 112CS.

b. In the MPS product page, locate the most recent firmware file, release

notes, and firmware update instructions. Save these files on your computer’s hard drive, and note the file path of the folder where the files have been saved.

2. Open a communications utility program such as HyperTerminal and select the COM port that is connected to the switcher’s RS-232 port. Protocol for RS-232 communication with the MPS switcher is as follows:

• 9600 baud

• 8 data bits

• 1 stop bit

• no parity (none)

• no flow control (none)

The firmware upload process can take several minutes. If HyperTerminal’s echo function is turned off, you have no indication that the upload is progressing. If desired, turn on the echo function as follows: Click File > Properties > Settings> ASCII Setup. Make sure that the echo feature is turned on (checked, as shown below), then click OK twice.

PRELIMINARY

5-7MPS Series • Programmer’s Guide

Programmer’s Guide, cont’d

3. Cycle power to the switcher: disconnect power for a few moments, reconnect

power, and press the computer keyboard’s ? (question mark) key.

You have approximately 2 seconds or less to press the ? key. If that time lapses and the ? key has not been pressed, repeat step 3.

4. Press D on the keyboard, then type Download. This text is case-sensitive. The

computer responds with a “Ready” prompt.

5. Click Transfer > Send text file... .

6. Select All files (*.*) from the Files of type: drop-down box.

7. Locate the folder where the firmware upgrade file is stored. Select that file.

Ensure that the firmware is for the MPS 112 Series switchers. Valid firmware files have a file extension “.s19”. Any other file extension is not a valid firmware upgrade for the switcher.

8. Click Open. Firmware uploading begins. If HyperTerminal’s echo function is

turned on, HyperTerminal displays the text of the firmware file scrolling (as in the screen excerpt below) as it is uploaded to the switcher.

PRELIMINARY

9. After several minutes the firmware uploading is completed. Press the Enter

10. Exit HyperTerminal.
