Wireless S88 Feedback Module

My temporary model railroad layout stretches from the office through the hall into the living room. The PC which I use to control the trains is in the office. How do I detect that a train arrived in the living room without any wires running across the hall? I designed a RF transmitter module and a RF receiver module to monitor contacts remotely. The transmitter can sense 4 contacts, encodes the state to a serial data stream and transmits the data. The receiver decodes the serial data into 4 separate lines and feeds them into the S88 bus. The receiver is a semi-complete S88 module and can be connected directly to the S88 bus, but has to be the last module on the bus. The transmitter takes power directly from the track and needs no additional power supply.read more »
