A USB Port Status indicator illuminates to show when the PC Port is operating to specification.

Transmit and Receive LED indicators show the network traffic and are ideal for diagnosing problems. The Transmit indicator illuminates when the PC sends commands to sensors on the network. The Receive Indicator shows when a sensor sends information to the PC.
