2 IR/Serial Output ports — Depending on how the switcher is configured via
the configuration software, these ports output either infrared signals or
unidirectional RS-232 signals for controlling various devices such as VCRs
and DVD players. Before it can be used for controlling a device, each port
must be set up via the configuration software for either IR or RS-232
communication and associated with a device driver.
For RS-232 output (-5 VDC to +5 VDC), use the illustration below as a
wiring guide, then plug a serial cable into this captive screw connector.
RS-232 default protocol :
• RS-232
• 9600 baud
• no parity
• 8 data bits
• 1 stop bit
• pacing = 0 ms

(See note.)
Maximum distances from the System 5 IP to the device being controlled may
vary up to 200 feet (61 m). Factors such as cable gauge, baud rates,
environment, and output levels (from the switcher and the device being
controlled) all affect transmission distance. Distances of about 50 feet (15 m)
are typically not a problem. In some cases the System 5 IP may be capable of
transmitting and controlling a given device via RS-232 up to 250 feet (76 m)
away.
For infrared (IR) output (0 to +5 VDC), wire an IR Emitter (2 emitters,
maximum, per port) as shown in the following picture for a modulated or
demodulated signal and ground. For specific information about wiring
more than one IR Emitter per port, refer to the Extron IR Emitter Installation
Guide, part #68-808-01. Alternatively, an Extron IR Broadcaster can be
connected here if you need to send out IR signals to a wider area than is
possible for an IR Emitter. The IR Broadcaster requires a +12 VDC power
connection. The +V and ground pins of the Projector Control port can be
used to provide this power.
