Dispatcher Panel for "Concept" Layout
The following interface boards will directly interface (pin by pin) with the terminal strips on the Dispatcher Panel. A custom interconnecting cable will be used to mate with the Dispatcher Panel.
Turnout Control Interface.
This interface provides signals from my MTH turnout solenoids. Each LED which shows turnout position is wired directly to each MTH solenoid (red position and green position). The interface module also includes a diode and series current limiting resistor for each LED. The LEDs are designated as E, N, S or Y.
Block Control Interface.
This interface provides a 12vdc signal which is provided via my MTH "AIU". I use the "ACC" terminals to select a track "block". This determines whether the track is "powered" or "not-powered". This same 12vdc signal is used to activate a "power" relay which connects the "TIU" output signal to the track. The block control interface also provides a current limiting resistor for each of the LEDs. These LEDs are all designated as "B".
