LED now flashes), then press and release the Red button (the flashing Rx LED extinguishes).

Input signals may now be connected to the input terminals of the module. If the module is
operating correctly, then the input signals will be reflected to the corresponding output on the
same module. For example, if DI 1 is connected to common - i.e. the first digital input is
turned "ON" - then DO 1 will activate, if the module is functional. Similarly, if a 12mA
signal is connected to AI 2, then a 12mA signal should be able to be measured from AO 2, if
the module is functioning correctly.
If a module does not pass its self test function, then it should be returned to an authorised
service agent for attention

Radio Testing using Tone Reversals
This function allows the unit to be configured to continuously transmit a sequence of alternate
zeros and ones on the radio. This function provides the facility to check VSWR of antennas
during installation, as well as checking the fade margin of the path between two units (see
below - received signal strength indication).
The tone reversals function is initiated by setting all of the DIL switches to ON, and holding
down the red button for approximately 5 seconds( until the RX LED lights continuously). On
releasing the button, the RX LED will flash continuously, and the TX LED will light,
indicating that the radio transmitter is on.
To finish the test, push the red button again or re-power the module.

Diagnostics functions
To aid in the checking and set-up of the 105 unit, a user friendly menu provides access to
diagnostic functions in the 105. Use of the diagnostics menu does not affect module
configuration.
The diagnostics functions can be accessed from the E Series Config software - the same
software package used to configure the modules. Connect the laptop or PC to the module
using a configuration RS232 cable.
Either open the archived project containing the module, or start a New Project and select
“Load a New Unit” - select the correct type of module. After the unit has loaded, select the
Diagnostics box.
