.
Digital I/O (FIRSTPORTA Bit 0 through FOURTHPORTC Bit 7)
You can connect 96 digital I/O lines to the two 50-pin connectors. Each digital port group is divided into two
8-bit ports and two 4-bit ports and is a discrete emulation of 82C55 mode zero operation. You can configure
each port independently for either input or output.
Output (sink) current limits
Each DIO pin can sink 64 mA maximum when configured for output.
Output (source) current limits
Each DIO pin can source 24 mA maximum when configured for output.

Power outputs
The USB-DIO96H/50 has two +5 V power output pins (
5V
). A total of 50 mA may be drawn from these
outputs.
Caution!
Each
5V
power connection is an output. Do not connect to an external power supply or you may
damage the USB-DIO96H/50 and possibly the computer.
Ground
Each 50-pin header provides a ground pin (
GND
) that provide a common ground for all digital functions on the
connector.
