Bidirectional Control and Communication Connections and Features
B
5-pole COM ports, RS-232/RS-422*/RS-485* —
Use COM ports for serial control of a display or other device and to receive status
messages from the connected devices. These ports can send
commands from a driver file. RS-232 is the
default mode of operation.
IPL Pro Series serial protocol:
•
300 to 115200 baud (9600 baud = default)
•
8 (default) or 7 data bits
•
1 (default) or 2 stop bits
•
No parity (default), even, odd, mark, or space
parity
•
Flow control support (default = none):
hardware and software (XON, XOFF)
*Supported serial formats vary depending on
the model and the COM port, as shown at
right.
Use the following diagram as a wiring guide to
cable the IPL to other devices.

Wiring COM ports for Serial Control
For bidirectional serial communication, the transmit, ground, and receive pins must be wired
at both the IPL Pro Series and the other device. Each projector or other device may require
different wiring. For details, see the manual for that equipment or read the Extron device
driver communication sheet, which is included with the drivers.
NOTE:
Maximum distances between the IPL and 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 IPL 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 IPL may
be capable of transmitting and controlling a given device via RS-232 up to 250 feet (76 m)
away, but the RS-232 response levels of that device may be too low for the IPL to detect.

TIP:
Comm-Link (CTL

recommended
for these

best results and
to avoid short

of bare wires) for
