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.
