The CMRI Node Test Program


The CMRI Node Test Program is a general purpose program that allows you to test the inputs and outputs on your model railroad from the railroad's CMRI computer, through the individual nodes, and finally on to the device at the end of the furthest I/O wires. The program displays a matrix of all the individual inputs to the node under test on the computer's screen, showing the state of each individual input in real time. The program also allows you to turn on and off individual output lines from the computer and confirm that the proper action takes place on the layout.
