At the ELCO connector, six input signals are used by the Real Time Unit to identify which harness connector is attached to the module. The five signals ID_CBL0 :4 are pulled up to 5V through a 100K Ohms. The sixth signal is GND.
When the harness connector is plugged to the ELCO-56 connector, it grounds the appropriate signals. The FPGA interprets the signal values in a 6-bit Cable ID value and relays this value to the simulation model. The value is also displayed on the run-time panel of the module.
