Bidirectional Control and Communication Connections and Features
B
5-pole COM ports, RS-232/RS-422*/RS-485* (see figure 7 , on page 13)
— 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, or odd 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.

Figure 9. 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 are generally
up to 200 feet (61 m) but may vary based on factors such as cable gauge, baud rates,
environment, and output levels (from the IPL and the device being controlled).
