1.4.3 COM PORT
Integra-TR is configured as DCE. DTE devices should be connected using a nine-conductor pin-to-pin straight cable (PN 697-
4008-408). Some RTUs or PLCs may require a special cable to route the signals correctly. Refer to your data equipment
documentation package.
DTE baud rates from 1200 to 19200 are supported. Integra-TR's are factory set for or 9600 b/s, 8 bits, no parity, and 1 stop
bit. Unless required by your operating protocol, we advise restricting port speed to be equal to or less than the RF network
speed.
