Connectors and Status Indicators
Front Panel
Connections to Ethernet, USB host and RS232 are available on the front panel.
There are 4 status lights on the front panel of AVIT . For all new or upgraded units (v2.0.2 and
later), these status lights are useful for troubleshooting the AVIT’s connection to a PC.

The yellow warning light indicates that AVIT is communicating with the vehicle. Do not
disconnect while this is illuminated! If you interrupt a reflash while the vehicle’s ECU is blank
or only partially programmed, the module may be unrecoverable. Refer to Table 1 for a
description of the other status lights.
