Reading the VHF receiver status
Selecting ‘Read’ retrieves and displays all of the relevant
status registers from the VHF receiver.
Of importance to the operator are:
1) That the status is OK
2) The Rssi level of the received signal
3) That the Frequency is as set and expected
4) That the Threshold level is as set and expected
Once this command is invoked, the receiver will be continuously re-read every 1 second and the
Rssi figure will be updated. This is extremely useful in checking the installation (aerials, down-feed
etc.) and setting up the receiver.
6.2.2 Cellular Radio
If a cellular module is fitted the basic module details, signal strength and quality can be obtained
and a network ‘ping’ to test the network connection are available.
These simple routines are useful in fault finding and diagnostics.
Read returns the basic information about the module and the network characteristics. In the
example above the module is attached to the UK O2 network with a reasonable signal strength
and low Bit Error Rate (BER) which is a measure of network quality.
Ping performs a network access ping to the service provider network. This test will take a few
seconds to complete.
