Baud rates from 300 – 9600 are supported. Un-
less required by your operating protocol, we
advise restricting port speed to be equal to or
less than the RF network speed.

3 Wire Connection (DOX)
The Integra-T provides and expects normal
handshaking signals, such as CTS, DCD and
DSR, for DTE using such signals. However, it
can also be operated in DOX mode (Data Oper-
ating Transmission) with only Transmit Data,
Receive Data and Ground (“3 wire interface”).

tegra RSS, RRSS and RDS programs and to
provide numeric diagnostic information.
