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 V104, 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 V104 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 V104 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.
