2.8 TESTING MODEM WITH RADAR LEVEL SENSOR
2.8.1 COMMAND-LINE INTERFACE
This example will show you how to test GSM modem with the Radar Level Sensor (RLR-0002-
1). We use a HyperTerminal session in Windows to communicate with the GSM modem
connected to the RLR-0002-1 sensor.
In one side you should have the RLR-0002-1 sensor connected to the GSM modem (See
configuration in COMMAND LINE INTERFACE section, page 7) and in the other side your PC
connected to a phone line.
First you have to start a Hyper Terminal session on Windows as follows: Start > Programs >
Accessories > Communication > Hyper Terminal. This will show this window.
