Connecting the MPS Switcher
The MPS switcher can be connected to as many as 12 input devices simultaneously
and can output to as many as three devices simultaneously, or one at a time. Follow
the steps below and see the installation example in figure 2-4.
1
Turn off power to the MPS switcher and all other devices that will be
connected.
2
If the MPS switcher is to be rack, table/wall, or through-desk mounted,
position the brackets and insert the mounting screws. See the Mounting the
Switcher, earlier in this chapter.
3
Attach up to four VGA, four S-video, and four video (composite) input
devices to the MPS switcher.
4
Connect the switcher’s VGA, S-video, and video (composite) outputs (up to
three, one of each video format) to a projector’s inputs.
5
For stereo audio input, connect up to 12 audio sources to the switcher’s audio
inputs of the VGA, S-video, or video (composite) groups (up to four for each
group). See the following Audio input and output section for connections.
6
For stereo output, connect an audio output device to each of the three groups
and one audio amplifier to the Program Audio connectors. Refer to Audio
input and output for wiring diagrams.
7
If the MPS switcher is to be connected to a computer or host controller for
remote control, connect the host’s RS-232 cable to the 9-pin female RS-232
connector of the MPS unit. For an RS-232 pinout table, see Remote connection
later in this chapter.
