MPS Series 1 Chapter One Introduction About the MPS Series MPS Series Features
Introduction 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.
MPS 112 Series 2 Chapter Two Installation Mounting the Switcher Rear Panel Connectors Connecting the MPS Switcher
Installation Mounting the Switcher The MPS 112 and MPS 112CS are housed in 1U high, 17.4" wide metal enclosures that are rack- or desk-mountable. The MBD 149 1U through-desk and rack 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 the optional Extron MBU 149 1U under-desk mounting kit (#70-222-01).
5. Reliable earthing (grounding) — Maintain reliable grounding of rackmounted 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.

Switcher Mode controls 12 Separate Switcher mode — This is the secondary function of this button. Press and release this button while pressing and holding the Mode button ( 14 ) to select the Separate Switcher mode. The associated LED indicates if the Separate Switcher mode is on (when lit) or off. When the Mode button is released, the LED resumes input indication. 13 Single Switcher mode — This is the secondary function of this button.
Operation, cont’d View mode To view the switcher’s current mode and microphone power settings, press and hold the Mode button for more than 2 seconds. The LEDs on the front panel change from input indication to setting indication. To change a setting, continue to hold the Mode button, and press the button that corresponds to the setting you want to change. Figure 3-3 shows the front panel buttons and LEDs that are active during View mode.
Front panel security lockout (Executive mode) To prevent unauthorized changes, Executive mode locks all functions except input selection functions and Program Audio Volume control. To toggle the Executive mode on or off, press and hold the Mode button for more than 2 seconds until the front panel LEDs change to View mode, then press and release the fourth input button of the VGA/Audio group. The Exec Mode LED turns on to indicate that Executive mode is on, and it turns off to indicate Executive mode is off.
Operation, cont’d Program audio breakaway Separate Switcher mode provides audio breakaway by allowing you to route the audio signal from any input group to the program audio output, independently from the video signal. For units with firmware version 1.10 and above: To select an input for program audio breakaway, first set the Follow sub-mode off. (See the instructions under Follow sub-mode below.
Program audio mute To mute the program audio output, press the Program Audio Mute button. The indicator LED to the right of the button lights when the program audio is muted. Press the Program Audio Mute button again to unmute the output. Program audio mute does not mute the microphone. Talk-over (program ducking) When the MPS detects a voice (an audio signal at a level above the “talk-over” threshold) at the mic input, the MPS immediately lowers (“ducks”) the program audio volume.
Operation, cont’d Speak into the microphone in a normal voice; the main program audio level should drop moderately. If not, lower the threshold by pressing and holding the Mix button and turning the Mic Volume knob counterclockwise. 4. Stop speaking into the microphone; the main program audio should recover to the previous level after approximately four seconds. If it does not, increase the threshold by pressing and holding the Mix button and turning the Mic Volume knob clockwise. PRELIMINARY 3.
MPS Series 4 Chapter Four Windows®-based Control Program Installing the Windows-based Control Software Using the Software Uploading Firmware Updates
Windows®-based Control Program The Windows-based Control Program (Extron part number 29-060-01) for controlling the MPS Series switchers via RS-232 requires Windows 95/98, NT, or later. It provides remote control of MPS switcher functions. Installing the Windows-based Control Software The program is contained on a CD, and it occupies approximately 2.5 MB (megabytes) of hard drive space. Run the program from the hard drive. To install the software from the CD onto the hard drive, run SETUP.
active and its LED is off. The virtual LED for the new input within the new group flashes. See pages 3-4 and 3-5 for information about program audio and microphone controls. The microphone threshold and ducking level can be adjusted after you click the Mix button to activate the audio mixing feature. Program audio ducking is available on MPS switchers that have firmware version 1.10 or higher. Earlier firmware versions do not support ducking.
Windows®-based Control Program, cont’d 7. Click OK to bring up the file selection window. Locate and select the file you saved in step 2 and click Open. Valid firmware update files have the file extension “.S19.” Files with other file extensions are not firmware update files. 8. After opening the file, click OK, then remove power from the unit. Power the unit back up to start uploading the firmware update. The upload process may take several minutes.
MPS Series 5 Chapter Five Programmer’s Guide Remote Control Port (RS-232) Host-to-MPS Communications Command/Response Tables
Programmer’s Guide Remote Control Port (RS-232) The MPS switcher RS-232 port connector is used to connect to a host or external controlling device, such as a computer or control system, which can generate the proper command codes and recognize the switcher’s responses. The cable used to connect the RS-232 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.
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.

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.
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.
