ChipNum

1 or 2

RegNum

LOADREG1 through LOADREG6

LoadValue

Values up to 65,535 (216 – 1) may be used. (Refer to Visual Basic signed integers in the Counter Hardware topic for more information.)

## Digital I/O

Functions

UL: cbDIn(), cbDOut(), cbDBitIn(), cbDBitOut(), cbDConfigPort()

UL for .NET: DIn(), DOut(), DBitIn(), DBitOut(),DConfigPort()

PortNum

0 to 15 using PORTCL

BitNum

0 to 39 using FIRSTPORTA

## Hardware considerations

##### Argument value vs. configuration

These boards have two 8536 chips, which have both counter and digital I/O and interrupt vectoring capabilities. The numbers stated for digital I/O apply when both chips are configured for the maximum number of digital devices. The numbers stated for counter I/O apply when both chips are configured for the maximum number of counter devices.
