5 DIAGNOSTICS AND TESTING
5.1 System Problems
Most problems relate to incorrect configuration, or radio path problems. Before installing the
505K module, "bench-test" its operation with the receiving 905U module alongside. If the
505K does not work properly in this test, it will not work properly installed. If problems are
found, check the configuration.
If the bench-test is successful, however problems are experienced after installation, check
the radio path (refer to the 105U User Manual for radio path testing).
The 505K provides the following diagnostic features which will help to identify problems.
5.2 LED Indicators
Normally the green OK LED on the front panel will flash briefly every 10 seconds. When the
OK LED extinguishes a sleepmode state is indicated conserving the 505K's battery power. If
the OK LED does not flash, a flat battery condition or an internal failure may exist. If the
505K module is located outside, then it will be difficult to see when the LED indicators are
on. Remove the front lid of the 505K to see the LED's better.
The yellow TX LED will flash whenever a radio transmission occurs.
Table of indicator conditions
INDICATOR CONDITION MEANING
OK LED ON Flashes briefly Normal Operation
OK LED OFF Continuously Supply fail or Battery voltage low
CPU failure
OK LED ON Continuously Analogue loop on
Configuration cable connected
TX LED ON Flashes briefly Radio transmitting
5.3 Diagnostic Features
The configuration software provides some diagnostic features to help identify problems. To
use these features, connect the 905K to a PC using a RS232 cable and run the configuration
software. The OK LED will light continuously once the module is in configuration mode.
Note : The OK LED will generally not light continuously unless the cable is in place and the
configuration software is running.
