Rtu-To-Radio Connection - Motorola IRRInet-M DC Owner's Manual

There are newer commercial modems which support RS232E, for which the RS232E+ adapter
should be used. To connect the RTU (via Port 1) to such a radio modem, use the FTN6359B
(RS232E+) adapter, which ends with the male 9-pin, D-type connector.
When the connector is facing upwards, the left-hand pin is Pin No. 1, and
the right-hand pin is Pin No. 8.

Accessories. For installation instructions, see Installation of IRRInet-M with
