» Functional Description
The PIO-D48 provides 48 TTL digital I/O lines.
The PIO-D48 consists of two 24-bit bi-direction ports.
Each 24-bit port supports three of 8-bit groups (A, B, C).
Each 8-bit group can be configured to function as either inputs or latched outputs.
All groups are configured as inputs upon power-up or reset.
Outputs of the I/O buffers are pulled up through 10K resistors to +5VDC.
Outputs can be changed to pull-down by jumper selection on the board.
This pull-up / pull-down mechanism assures that there are no erroneous outputs at power-up until the board is initialized by application software.
The PIO-D48 has one D-sub connector and one 50-pin flat-cable header.
The header can be connected to a 50-pin flat-cable.
The flat-cable can be connected to ADP-37 / PCI or ADP-50 / PCI adapters. The adapter can be fixed on the chassis.
It can be installed in a 5 V PCI bus and can support truly "Plug & Play".
