Serial Test

Serial Test Plugin

This is a plugin to test 2 serial ports. It will report if data sent on one port has been received on another serial port. For this to work, the two serial ports must be connected via a crossover cable, so that the RxD of one device is sent to the TxD of the other device, and vice versa. Contact Ardexa if you are not sure how to set this up. If it works ok, running the discover command (see below), will show something like: the following. Please check the sent and received messages are the same.

Setting speed of both ports to 38400
