Our programmable devices (such as TPP2 and TPP3) have the unique ability to process input from card readers with clock/data or Wiegand interface. This is achieved through the ser. object running in the clock/data or Wiegand mode. Tibbit #08 implements necessary hardware.
In order to be able to process card reader output, this Tibbit has to be connected to the RX and CTS lines of the CPU's UART (see [SER]).
When connecting a clock/data reader, wire the clock line to IO1, and the data line to IO2. Set the CONTROL line to LOW — this selects the clock/data mode for the Tibbit's hardware.
