3. Connectors
3.1. Antenna
The radio modem is fitted with two SMA type connectors for connecting an antenna. The connector
labelled Rx is for the receiver, and Tx for the transmitter (up to 25 W). Use the corresponding type of
connector with matched impedance as the mate. We recommend an RG158 cable for the serial lead.

Important
The radio modem cannot be connected to the power supply without the antenna connected
(or corresponding artificial load). Otherwise this could lead to damage to the radio part of
the modem.

the modem.
3.2. Serial Interface
The radio modem can be equipped with serial ports RS232 or RS422/485, the ports can be optical
isolated. According to the configuration of the radio modem it is possible to use a terminal block or
DSUB 9 (Canon) connectors for connecting data cables via the serial interface. See Chapter Labelling
