5.2 LEDs for Serial DF1 Protocol Ports
Troubleshooting the operation of the serial DF1 protocol ports can be performed
using several methods.
The first and quickest is to scan the LEDs on the module to determine the
existence and possibly the cause of a problem. This section provides insight into
the operation of the Serial Port status LEDs.
Some ProLinx modules will include three extra serial ports. Each of these serial
ports has two LEDs indicating status.
