When doing a Find Stations on 2300-XX stations, the TX and RX leds on the station will only flash when a valid command has been detected by the station (thus a read of data of station number matching the address set at the dip switches).

This is unlike the 2100-XX stations, the RX leds on the stations flash for ANY station commands on a data loop, and only when a valid command is detected will the TX and RX leds flash together.
