Installation
Check List
The following points must be taken into account when installing and configuring a radio modem:
All operating voltages of all the equipment concerned must always be switched OFF before connecting the
serial interface cable.
When considering the exact placement of a radio modem and/or its antenna, the following points must be
taken into account to guarantee optimal results:
•
The antenna should be installed in open space as far as possible from any possible sources of
interference
•
The radio modem should not be installed onto a strongly vibrating surface
•
The radio modem should be installed in such a way as to minimize exposure to direct sunlight.
To ensure reliable operation the voltage output of the power supply used must be stable enough and the
current capability of the power supply must be sufficient.
The antenna must be installed according to instructions.
Serial interface settings between the radio modem and the terminal unit must correspond to each other.
All radio modems in the same system must be configured using equal radio settings (radio frequency, channel
spacing, compatibility, forward error correction and data field length).
Installation of a Radio Data Modem
The radio modem should be installed with the installation accessories supplied with the radio modem.
RS-232 Wiring
Refer to “Data Connector” on page 47.
Fuse
A proper fuse must be connected in between the radio modem and the power supply. The correct value is 15A
for the SRL-35.
In the SRL-35, the voltage is limited to 16V.
