3. Connectors

3.1. Antenna

The cable for connecting the antenna is fitted with an N type connector. Use a connector of the corres-

ponding type and impedance as its mate. We recommend using an RG213 cable for aerial leads up

to 25 m in length and a H1000 for longer leads.

Important

CAUTION. 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.

3.2. Serial Interface

The router can be equipped with serial ports RS232 or RS422/485, the ports can be optical isolated.

According to the configuration it is possible to use a terminal block or DSUB 9 (Canon) connectors for

connecting data cables via the serial interface. See Chapter Dimensional Diagram and Labeling. Data

rate on the serial interface can be from 200 bps to 230,400 bps.
