The audio level for each local input can be individually set via the front panel
or serial port control to ensure that the level on the output does not vary from
input to input. See chapter 3, “Operation”, chapter 4, “Programmer’s Guide”,
chapter 5, “Matrix Software”,andchapter6,“HTMLOperation”, for details.

set these DIP switches to the Local (up) position to select the local
(RGB video and audio) input. Set the DIP switches to the RJ-45
(down) position to select the MTP input.
RS-232 output inserts

RS-232 Output Insert connectors — For bidirectional RS-232 data that is
routed to a specific (unswitchable) TP output, connect a serial device to one of
these 3.5 mm, 3-pole captive screw connectors. Figure 2-7 shows how to wire
the connectors.
