In an electronically controlled RAILWAY locomotive throttle controller system having a central processor unit and a plurality of trainlines, such trainlines carrying binary voltage signals derived from corresponding binary signals in such central processor unit, a method for transmitting, for a group of said trainlines, herein numbered as NT, the binary voltage signals back to such central processor unit for diagnostic purposes. Such method includes the steps of applying, for the group of NT trainlines, their binary voltage signals to a frequency generator which will generate a signal having a frequency characteristic of such binary voltage signals. The frequency having a different value for every possible combination of binary signals from such trainlines. Transmitting such frequency signal back to the central processor unit and processing such frequency signal, in the central processor unit, to recover NT binary signals corresponding to such binary voltage signals on the trainlines in such group of trainlines. |
