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.

Pin Name Function
1 DCD
Output: Always asserted or asserted when receive RF carrier present (selectable via Field
Programming Software)
2 RXD Output: Data from Integra-TR to DTE
3 TXD Input: Data from DTE to Integra-TR
4 DTR Input: Ignored
5 GND Signal and chassis ground
6 DSR Output: always positive
7 RTS Input: Used as a “begin transmission” signal in RTS mode
8 CTS
Output: Used for handshaking in RTS mode and used for flow control in DOX mode RTS mode: RTS
to CTS delay in 4 ms DOX mode: CTS always asserted except when data overflow is detected
9 RI Not internally connected, reserved
The DE-9F pin out is shown in Figure 2 for reference.
