Connecting the MPX 423 A Matrix Switcher

The MPX 423 A matrix switcher can be connected to as many as 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 2-4.

Turn off power to the MPX 423 A matrix switcher and all other devices that

will be connected.

If the MPX 423 A matrix switcher is to be rack, table or furniture mounted,

position the brackets and insert the mounting screws. See the Mounting the

Matrix Switcher, earlier in this chapter.

Attach up to four VGA, four composite video, and four S-video, input devices

to the MPX 423 A matrix switcher.

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).

For audio input, connect up to 12 audio sources to the switcher’s audio inputs

of the VGA, Video (composite), or S-video groups (up to 4 for each group).

See figure 2-4 for a connection diagram.

For audio output, connect an audio output device to each of the two audio

outputs. See Audio outputs in chapter 3, Operation for wiring diagrams.

If the MPX 423 A matrix 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 MPX unit. For an RS-232 pinout table, see the

RS-232 and Ethernet Control later in this chapter.

For an Ethernet connection, plug one end of a Cat 5, straight-through Ethernet

cable to the RJ-45 LAN port of the switcher. See RS-232 and Ethernet Control

later in this chapter for pinout instructions.

Power up the input and output devices, then connect power to the rear AC

connector of the MPX 423 A matrix switcher.
