2.8 Power Management Controller PM104 (optional)

The Power Management Controller (PM104) is a microcontroller “plug-in” module for timed on-off control of the HE104, control of the optional battery charger and generation of interrupts to the PC/104 host CPU. The PM104 is programmed in a high level “controller basic language” called Pbasic. To program the PM104, connect the program cable (PM104-Cable) to connector CN4 on the HE104 and to the parallel port of any PC compatible computer. PM104 programs can be directly downloaded or updated using the PM104 utility software.

Connector CN4 Pinout, PM104 Program Connector:

-Terminal 1: PM104 Power (leave disconnected if HE104 powered)

-Terminal 2: Common, connect to pin 25 of PC parallel port.

-Terminal 3: PC0, connect to pin 11 (busy) of PC parallel port.

-Terminal 4: PCI, connect to pin 2 (DO) of PC parallel port.
