NOTES: • The length of exposed wires is critical. The ideal length is 3/16 inch (5 mm).
z z
If the stripped section of wire is longer than 3/16 inch, the exposed
wires may touch, causing a short circuit.
z z
If the stripped section of wire is shorter than 3/16 inch, wires can be
easily pulled out even if tightly fastened by the captive screws.
• Figure 7 identifies the tip, ring, and sleeve. A mono audio connector
consists of the tip and sleeve. A stereo audio connector consists of the
tip, ring and sleeve. The tip, ring, and sleeve wires are also shown on the
captive screw audio connector diagrams (see
figure 6 on the previous
page and figure 9 on the next page).

Figure 7. Typical Audio Connectors
The audio level for each input can be individually set via the front panel or Ethernet or
RS-232 control to ensure that the level on the output does not vary from input to input
(see the “
Operation ” section, page 46; the “ Programming Guide ” section, page 76;
the “ Matrix Software ” section, page 105; and the “ HTML Operation ” section,
page 136).

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 8 shows how to wire the
connectors.

Figure 8. RS-232 Output Insert Wiring
For the RS-232 Output Insert to be available on the TP output, the insert must be
enabled via an SIS command, the Windows-based control program, or an MTPX
Plus HTML page (see the “
Programming Guide ” section, page 734; the “ Matrix
Software ” section, page 106; and the “ HTML Operation ” section, page 134).
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.
