If the RX LED is lit when no data is being transmitted then there might be another user on the
channel. Select an RF channel on the DIL switches were the RX LED is not lit. Remember to
switch the power off and then on again when you make a change in the DIL switch settings to
load the new value.
If RX LED is flickering on all RF channels then look for a source of local interference such as
a switch mode power supply or a computer in close proximity.
If there are other radio modems or radio telemetry systems operating on adjacent frequencies
on the same site then the antenna on your system must be mounted at least 3m away from
the antenna of the other systems. This will prevent the transmitter of one system interfering
with the receiver of the other.
8.3 Corrupted
Data
Corrupted data can be caused by poor power supplies.
Check that the power supply is regulated at 12V and has a ripple of less than 50mV on load.
It must also be capable of delivering an inrush current of 0.7Amps for 20mSec. when the
radio modem starts its transmit cycle.
The ripple voltage can be measured with a voltmeter set on A.C. volts.
8.4 Radio
Path
The radio path can be tested by configuring the transmitting modem to the Repeater Mode.
Exit the configuration menu and transmit a character from the dumb terminal
This will be echoed back from the distant modem if there is a good transmission path.
