From the project

Serial Model Railroad Control

This is a set of PCBs and software to control a model railroad with RS485 data buss.

Anamation Controller, 8 servos Block Detector, detects voltage across diode/resistor Optical Detector, broken beam or reflected beam

When a command packet is received from RX1 (RS485): Source=any, Destination=Me: Parse and Process the command. Send any requested data back to the sender on TX1 (RS485). Source=any, Destination=Master: Retransmit on TX2 (USB) Source=any, Destination= other than Master or Me do nothing.
