Connecting the Matrix Switcher
The MPX 423 A matrix switcher connects to up to 12 input devices simultaneously,
and can output to as many as six devices simultaneously, or one at a time.
Follow the steps below and see the installation example in figure 2-3.
1.
Turn off power to the MPX 423 A matrix switcher and all other devices that
will be connected.
2.
Mount the MPX 423 A in the desired position on a desk, in a rack, or under a
table as described previously in this chapter.
3.
Connect up to four VGA, four composite video, and four S-video input
devices to the rear panel of the MPX 423 A matrix switcher.
4.
Connect the switcher’s VGA, Video (composite), and S-video outputs (up to
six, two of each video format) to the inputs of the display(s).
5.
For audio input, connect up to 12 audio sources to the switcher’s audio inputs
of the Computer (VGA), Video (composite), or S-video groups (up to 4 for
each group).
6.
For audio output, connect an audio output device to each of the two audio
outputs. See “Audio outputs” in chapter 3 for wiring diagrams.
7.
If the matrix switcher is to be connected to a computer or host controller
for remote control of the unit, connect the host’s RS-232 cable to the RS-232
connector on the rear panel. For the RS-232 pinout table, see “RS-232 and
Ethernet Control” later in this chapter.
8.
For an Ethernet connection, plug a CAT 5, straight-through Ethernet cable
into the RJ-45 LAN port on the rear panel of the switcher. See “RS-232 and
Ethernet Control” later in this chapter for pinout instructions.
9.
Power up the input and output devices, then connect power to the rear AC
connector of the switcher.
