Troubleshooting Guide
This guide will concentrate on all relevant troubleshooting issues that may arise on the USG-2. Therefore, the cables
between the USG-2 hardware and any other devices should be checked as a matter of course, before continuing with
this guide.
Status LEDs
The USG-2 is fitted with three LEDs that can be a useful aid to fault diagnosis. Please refer to
“LED Behavior”
of this manual for the normal LED operation.
Technical Support and the Returns Procedure
All installation instructions and any warnings contained in this manual must be followed before contacting Actisense
technical support. If the troubleshooting guide did not help resolve the problem and an error persists, please contact
Actisense Technical Support to help trace the issue before considering the return of the product. If the Actisense
support engineer concludes that the USG-2 unit should be returned to Actisense, a ‘Return Merchandise Authorisation’
(RMA) number will be issued by the support engineer.
The RMA number must be clearly visible on both the external packaging and any documentation returned with
the product. Any returns sent without an RMA Number will incur a delay in being processed and a possible
charge. Any cables originally supplied with the product are to be included in the returned box.

Solution
No LEDs are illuminated.
Ensure the USB cable is firmly connected between the USG-2
and the computer. The Actisense USB drivers must be installed
correctly on the computer before USB power is enabled. When
an internet connection is available USB driver installation is
automatic, if not, manual installation instructions and USB drivers
are available from the Actisense website and on the CD provided.
Power is present and a Talker is connected but
the USG-2 isn’t receiving data from the Talker
(indicated by the green LED not blinking).
Check the wiring in accordance with
to ensure the Talker is wired correctly to the USG-2’s Listener
connections on the pluggable screwless connector.
The green LED on the USG-2 is blinking
(to indicate reception of data from the Talker)
but there is no data on the computer.
Check the COM port you are using in your software application is
the one allocated to the USG-2 by your OS. Also check the baud
rate you have selected matches the Talker device connected to
the USG-2.
The orange LED blinks (to indicate the USG-2 is
transmitting data to the Listener) but no data is
displayed on the Listener.
