PIO-48 User Manual
Introduction
The PIO-48 part number 4030 digital I/O interface provides 48 channels of buffered
drive digital I/O emulating 8255 mode zero. The PIO-48 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’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 three eight-bit groups. Each eight-bit group may be individually configured via
software command as input or output to best match your particular application
requirements.
The PIO-48 is designed to be used with a variety of Operating Systems including
Windows 98/NT/ME/2000/XP, Linux and DOS. The SeaI/O API (Application
Programmer Interface) included on CD with the PIO-48 provides a variety of useful
high-level function calls implemented as a Windows dynamic link library (DLL) and
as a Linux kernel module and library. In addition to the API, SeaI/O includes
sample code and utilities to simplify software development.

Card Setup
The PIO-48 contains several jumper straps for each port that must be set for proper
operation.
Address Selection
The PIO-48 occupies 8 consecutive I/O locations. Dip-switch SW1 sets the
base address for the PIO-48. 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.
Address Binary Switch Settings
1 2 3 4 5 6 7 8
280-287 10 1000 0XXX Off On Off On On On On On
2A0-2A7 10 1010 0XXX Off On Off On Off On On On
2E8-2EF 10 1110 1XXX Off On Off Off Off On Off On
2F8-2FF 10 1111 1XXX Off On Off Off Off Off Off On
3E8-3EF 11 1110 1XXX Off Off Off Off Off On Off Off
300-307 11 0000 0XXX Off Off On On On On On Off
328-32F 11 0010 1XXX Off Off On On Off On Off On
3F8-3FF 11 1111 1XXX Off Off Off Off Off Off Off On
Typically COM1: = 3F8h; COM2: = 2F8h; COM3: = 3E8h; COM4: = 2E8h.
The following illustration shows the correlation between the DIP-switch setting and
the address bits used to determine the base address. In the example below, address
300 is selected as the base address. Address 300 in binary is 10 0000 XXX where X
= a non-selectable address bit and address bit A9 is always a 1.
Address Selection Table
DIP-Switch Illustration
Note: Setting the switch ‘On’ or ‘Closed’ corresponds to a ‘0’ in the address, while
leaving it ‘Off’ or ‘Open’ corresponds to a ‘1’.

PIO-48 User Manual
Wait States
The PIO-48 has the option of inserting one 500 nS wait state for each access. This
may be required on certain machines with bus clocks in excess of 8 MHz. With the
wide variety of machines available, no concrete rules exist concerning wait states. If
the PIO-48 doesn't seem to be responding properly, try inserting a wait state.
To enable wait state insertion, set position 8 of the dip-switch to "ON". To disable
wait states, set position 8 "OFF".
Interrupt Headers J5 and J6
The headers marked J5 and J6 allow the use of interrupts with the parallel ports. J5
selects IRQ2 through IRQ7 for Port 1 (U9 and J1), while J6 selects the IRQ for Port
2 (U16 and J3).
Optional Cable Connector P4
Discrete access to both sides of all relays is provided by attaching the
optional cable (CA-108) to pin header P4 with the colored edge of the ribbon
cable attached to pin one. Removing all the jumpers connecting row P1 to P2
places the A-side of each relay at the on-board DB-37 and the B-side at the
optional cable’s DB-37.
