RS-232 Output Inserts
e 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 9 shows how to wire the connectors.

Figure 9. RS-232 Output Insert Wiring
CAUTION: The length of exposed wires is critical (see the CAUTIONS on page 14 for
details).
For the RS-232 Output Insert to be available on the TP output, the insert must be
enabled via an SIS command (see the “Programming Guide” section), the Matrix
Switchers Control Program (see the “Matrix Software“ section), or an MTPX Plus
HTML page (see the “HTML Operation” section).
Each RS-232 output insertion is dedicated to the output with that number; for example,
RS-232 Output Insert 1 is always routed to the Output 1 TP connector (when enabled
as described in the note above), RS-232 Output Insert 2 is routed to the Output 2 TP
connector, and so on.
NOTES: • When an RS-232 output insert is enabled, any content on the
audio/RS-232 wire pair for the TP input tied to that output is disabled.
• The switch time for the RS-232 output insert is 50 ms.
