PIO-48.PC104 User Manual
Introduction
The PIO-48.PC104 part number 3701 digital I/O interface provides 48 channels of
buffered drive digital I/O emulating 8255 mode zero. The PIO-48.PC104 can be
utilized for a variety of control and automation applications including control and
monitoring of TTL devices (e.g. LEDs, small solenoids, small relays) and
interfacing to solid-state relay racks (SSRs) for high-power AC or DC loads.
The PIO-48.PC104’s 48 digital I/O channels are accessed via two 50-pin header
connectors with industry-standard pin out. Each header provides 24 bits of digital
I/O divided into two eight-bit ports and two four bit ports for upper and lower
nibble. Each port may be individually configured via software command as input or
output to best match your particular application requirements.
The PIO-48.PC104 is designed to be used with a variety of Operating Systems
including Windows 98/NT/ME/2000/XP and DOS. The SeaI/O API (Application
Programmer Interface) included on CD with the PIO-48.PC104 provides a variety of
useful high-level function calls implemented as a Windows dynamic link library
(DLL). In addition to the API, SeaI/O includes sample code and utilities to simplify
software development.

Card Setup
Address Selection
The PIO-48.PC104 occupies 8 consecutive I/O locations. The DIP-switch (S1) is
used to set the base address for these locations and the IRQ mode options. Be careful
when selecting the base address as some selections conflict with existing PC ports.
The following table shows several examples that usually do not cause a conflict.
A9 A8 A7 A6 A5 A4

Interrupt Modes
DIP-Switch positions ‘S’ and ‘M’ on switch S1 selects the interrupt mode for each
adapter.
With the ‘S’ selected, the adapter is in a (S)hared interrupt mode, which allows more
than one adapter to access a single IRQ.
‘M’ indicates the inclusion of a 1K-ohm pull-down resistor required on one adapter
when sharing interrupts.
Set the switch to ‘S’ for shared interrupt mode on all adapters sharing an IRQ. On
one of the adapters sharing an interrupt set the switches for both ‘S’ and for ‘M’.
This provides the pull-down resistor circuit that makes sharing IRQs possible. If you
are using more than one compatible adapter in a bus you should only have one
adapter set to ‘M’.

PIO-48.PC104 User Manual
IRQ Selection
The PIO-48.PC104 has an interrupt selection jumper, which should be set prior to
use, if an interrupt is required by your application software. Consult the user manual
for the application software being used to determine the proper setting.
IRQ3
IRQ7
IRQ9
IRQ10
IRQ11
IRQ12
IRQ15
IRQ4
IRQ5
Note: The supplied driver for Windows and does not require, nor does it support
interrupts. It is recommended that this jumper be removed to prevent any resource
conflicts.
