3.1 Important Troubleshooting Notes
Always troubleshoot communication problems before working on battery-related and/or generator-
related problems. The embedded transponder runs off of the power supply’s USM2.5 logic voltages,
and does not require the sensing cables (from the batteries or the generator) to communicate.
1. USM2.5 Switch Set-up: The 8 position “DIP” switch on the USM2.5 board must be set correctly.
See the complete chart in the USM2.5 Status Monitor Operator’s and Technical Manual P/N
704-683-B0-xxx. Note that SW1-4 (the fourth switch from the front) must be turned ON when
using an internal Acterna transponder.

2. Transponder Address: The transponder address is the five (5) digit number printed on the sticker
on the FRONT of the Embedded Transponder Assembly, above the “F” connector. The address
is not the printed circuit board serial number (typically in the format of 1B followed by six
numbers) from the sticker on the PCB itself. The address can be verified from the SOC (Sys-
tems Operation Center).
3. Transponder Driver: The correct Acterna device driver must be downloaded from the HEC to the
transponder. The following is Acterna’s list of device drivers for embedded (internal) transponders
in Alpha Technologies XM2 power supplies, as of 17 October 2002.
