Appendix B: P5T Auxiliary Input Board
The P5 system is designed as a modular system, consisting of a base
board and expansion boards. This optional board adds 6 Trigger inputs
and a pair of motor voltage inputs to the P5 system. This is useful with
conventional remote control systems where train speed is determined by
reading motor voltage and where more than 2 trigger inputs are needed.
