Figure 12. 9-pin TRS RS-232 cable
This port is RS-232 only, with the following protocols:
• 9600 baud • no parity • 8 data bits
• 1 stop bit • no flow control
NOTE: The maximum distances from the transmitter or receiver to the controlling
device can vary up to 200 feet (61 m). Factors such as cable gauge, baud
rates, environment, and output levels (from the unit and the controlling
device) all affect transmission distance. Distances of about 50 feet (15 m)
are typically not a problem. In some cases, the unit may be capable of serial
communications via RS-232 up to 250 feet (76 m) away.
See “ Remote Control “ on page 20 for definitions of the SIS commands (serial
commands to control the transmitter via this connector) and software control.
