Introduction • About this User Guide • About the MPS 409 • Features About this User Guide This guide contains information to install, configure, and operate the Extron Electronics MPS 409, Media Presentation Switcher. In this guide, the MPS 409 may be referred to as “MPS”, “MPS 409” or “switcher”. About the MPS 409 The Extron MPS 409 is a multi video format Media Presentation Switcher for small presentation systems. The MPS 409 integrates several video switchers into one product.
• Program audio switcher — A four input, one output stereo audio switcher allows the audio input of any video group to be selected for the program audio output, with volume and mute control. The MPS 409 features balanced/unbalanced program audio output on a 5-pole captive screw connector. • Microphone/line input — One 3.5 mm captive screw connector is used for a balanced/unbalanced Mic or Line level input. The input has an adjustment range of -66 dB to +12 dB.
• +48V phantom microphone power — Powers a condenser microphone. • Provides +5 VDC, 250 mA power on the HDMI and DVI outputs for external peripheral devices • Internal universal power supply — The 100-240 VAC, 50-60 Hz, international power supply provides worldwide power compatibility.
Installation This section describes the installation and the operation of the MPS 409, including: • Mounting the Switcher • Rear Panel Connections • Cabling the MPS 409 Switcher Mounting the Switcher The MPS 409 is housed in 1U, full rack width metal enclosure rack- or desk-mountable. The MBD 149 1U through-desk and rack mounting kit (#70-077-03) is included with the switchers.
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. 5. Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted equipment.

Cabling the MPS 409 Switcher The MPS switcher can be connected to as many as 9 input devices simultaneously. It can output to as many as four devices (three in combine mode) simultaneously. Outputs can be configured for simultaneous outputs from each of the four input groups, VGA/YUV, DVI-D, HDMI, composite or one at a time from a selection of the nine inputs. Follow the steps below and see the installation example in figure 1. 1.

Microphone and Program Audio Controls h Mic Mute — Toggles the microphone mixer on and off to provide microphone talk-over for the program audio. The LED (when lit) indicates the microphone input is muted. i Mic Volume — This adjustment knob controls the volume of the microphone. Rotating the Mic Volume control unmutes the microphone. j Program Audio Mute — Toggles program audio on and off. The LED (when lit) indicates program audio is muted. When muted, inputs may be switched without unmuting.
Front Panel Operation The MPS switcher can be connected to as many as nine input devices and four output displays plus an audio amplifier. It operates in one of four switching modes: single (the default), separate, single-combine, or separate-combine. The functions of the front panel controls are described in the following sections. Each input group; VGA/YUV, DVI-D, HDMI, and composite, have one video and one audio output each.
Input Selection — Single Switcher Mode In single switcher mode (default) the switcher emulates a single nine input switcher (9x1). In this mode, when an input is selected from any group, the green LED indicator to the right of the button lights, and the selected input (video and audio) is routed to the output for that group. The selected audio is also connected to the program audio output. All other outputs, (except program audio) are muted.
Combine Mode Combine mode switches a selected HDMI/DVI input to the HDMI output, deactivating the DVI audio and video outputs. This enables the MPS 409 to function as one 5x1 HDMI/DVI and audio switcher, adding VGA/YUV and Video inputs. Combine mode can be used whether the switcher is in separate or single switch mode. All other inputs and outputs function according to the selected switcher mode.
Program Audio The selected audio input is routed to the program audio output according to the switcher mode. The input LED selected for program audio output blinks. Program Audio Selection Single switcher mode In single switcher mode, audio from the selected input is routed to the program audio output. If combine mode is active, when a DVI input is selected, DVI audio is available on the HDMI audio output and the program audio output.

These adjustments can be used to normalize the input audio levels so that output volume is consistent for all inputs.
Microphone Controls Mic on/off Mic volume and mute are controlled from the front panel. The Mic mute button toggles the Mic input on or off. The corresponding red LED illuminates when Mic volume has been shut off (muted). When the Mic input is enabled it is mixed with the program audio output. Mic volume is a stepped encoder, adjusted at a rate of 1 dB per step of the control. Clockwise rotation increases and counterclockwise decreases the Mic volume.
EDID Minder The DVI and VGA/YUV groups feature EDID Minder, ensuring that each input source reads the EDID of the output display even when not selected. The result is the video source powers up properly and reliably outputs content when selected. The EDID remains in the selected mode (automatic or user assigned) even after loss of power. The DVI group does not support HDCP by default. In order to support HDCP, EDID Minder must be disabled. EDID Minder can be disabled for the DVI group using SIS commands.
User assigned EDID Mode — Using SIS commands, an EDID file can be selected from a table of 19 EDID files. One additional EDID file location is reserved for user-loaded EDID files for the VGA and DVI groups. Once a user assigned EDID is chosen, the switcher stores it at the inputs and no longer polls for the EDID of a connected display. The chart below lists the native resolution of each factory EDID file and timing characteristics associated with each.
SIS Programming and Control This section discusses SIS programming and control of the MPS 409 including: • Connection Options • Host-to-MPS Communications • Command/Response Table • Updating Firmware Connection Options The MPS 409 can be remotely connected via a host computer or other device (such as a control system) attached to the rear panel RS‑232 port or the front panel USB Config port. The switcher can be set up and controlled using SIS (Simple Instruction Set) commands.
USB Configuration Port Drivers for the MPS 409 USB configuration port are loaded automatically when Dataviewer or Firmware Loader, included on the software disc or available at www.extron.com, are loaded. Host-to-MPS Communications The MPS switcher accepts Simple Instruction Set (SIS™) commands through the RS‑232 or USB configuration port. SIS commands consist of one or more characters per command field. They do not require special characters to begin or end the command character sequence.
Command/Response Table Using the 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 and an ASCII-to-hexadecimal (HEX) conversion table are shown below. Command and response examples are shown throughout the command/response table.
