either bit may be used. This virtual COM port driver is designed to work the same as
most serial cash drawers so that drivers for a serial cash drawer should work if mapped to
the correct COM port, normally COM5 in the 650 system.
The cash drawer can directly be accessed through two I/O ports, 280 hex and 281 hex.
Port 280 hex is an output only port and fires the cash drawer when toggled.
Port 281 hex is and input only port and read the status of the cash drawer.

Power Supply
The 650 uses a notebook type power supply that is normally mounted in the base of the
unit. The power supply is rated with an output of 19 VDC 7.1 Amps and has an input
rating of 100-240VAC at 50~60Hz 2.2Amps maximum. The power supply typically has
an efficiency rating of 85% under light loads and 90% under heavy loading. The power
supply connector is a four pin locking type that plugs into the system’s power input
connector located in the cable well.
