Troubleshooting guide
This guide will concentrate on all relevant troubleshooting issues above simple cable connection faults. Therefore, the
cables between the USG-1 hardware and any other devices should be checked as a matter of course, before continuing
with this guide.
Diagnostic LED
The USG-1 hardware has a bright LED that can be seen through the case to indicate when data is
either
received
or
transmitted. It can be used to debug potential problems. If you have both a talker and a listener connected, then you
can analyse which is working by disconnecting one of them or by stopping the PC from sending data.
Mode / Error condition
Required user response
LED does not flash when the
PC is sending data
Check that the PC program is sending data and that it has opened the comms port
assigned (by user) or allocated (by Windows Device Manager) to the USG-1
LED does not flash when the
Talker is sending data
Check that the Talker device is correctly connected to the USG-1, that it is powered
on, and that it is sending data.
In addition, the USB driver must be correctly
installed and the PC software must have the assigned comms port open for
the LED to flash
No data is being received
by the Listener, but LED is
flashing as PC is sending
Check that the Listener device is correctly connected to the USG-1, that it is powered
on, and that it is set to receive data at the Baud rate of the PC comms port.
If the error persists, the USG-1 unit should be returned to
Actisense
(refer to the
section).
Please contact Actisense before returning the
unit in order to obtain a Returns Number. Any returns sent without a Returns
Number will incur a delay in being processed.
