Figure 19. Serial and IR Insertion Connections
A
Over TP (inputs 7 and 8) ports — If desired, connect serial RS-232 signals,
modulated IR signals, or both to these 3.5 mm, 5-pole captive screw connectors to
insert bidirectional RS-232 and IR communications onto the associated inputs (see
“Serial and IR port connectors” to wire the cables).
B
Over TP (output 1C) port — If desired, connect a serial RS-232 signal, modulated IR
signal, or both to this 3.5 mm, 5-pole captive screw connector to insert bidirectional
RS-232 and IR communications onto the associated output (see “Serial and IR port
connectors” to wire the cables).
NOTE: These ports enable you to insert RS-232 control signals onto the same cable
that carries video and audio to extend them to the Over TP port of a connected
endpoint. The control signals can be inserted two ways:
• Ethernet to RS-232 insertion (see Ethernet to RS-232 Insertion on page 44),
in which a control signal applied to an IN1608 xi LAN port can be routed to the
RS-232 port of any connected twisted pair device.
• Captive screw insertion (see Captive Screw Signal Insertion on page 46), in
which a control signal applied to an RS-232 captive screw port is tied directly to the
same-numbered TP port (RS-232 input port 7 is tied to TP port 7 only, and 8 is tied
to 8).

NOTE: The length of the exposed wires is important. The ideal length is 3/16 inch
(5 mm) (see the audio input connector ATTENTION notifications on the previous page
for details).
