Introduction
The OME-PIO-D56/OME-OME-PIO-D24 provides 56/24 TTL digital I/O lines.
The OME-PIO-D56/OME-OME-PIO-D24 consists of one 24-bit bi-directional port,
one 16-bit input port and one 16-bit output port (only for OME-PIO-D56). The 24-bit
port supports three 8-bit groups PA, PB & PC. Each 8-bit group can be individually
configured to function as either an input or an output. All groups using 24-bit bidirectional ports are configured as inputs upon power-up or reset.
Use the OME-DB-24PD to connect the input port for either isolation purposes,
or to interface to the output port for relay control. The OME-PIO-D56/OME-PIO-D24
has one D-sub connector and two 20-pin flat-cable connectors (only for OME-PIOD56). The flat cable can be connected to an OME-ADP-20/PCI adapter. The adapter
can be fixed on the chassis. It can be installed in a 5V PCI bus and supports “Plug &
Play”.

Enabling I/O Operation
2.3.1
DI/DO Port Architecture (CON3)
Upon power-up, all D/I/O port (CON3) operations are disabled. The RESET\
signal controls the enable/disable state of D/I/O port. Refer to Sec. 3.3.1 for more
information about RESET\ signal. The power-up states are as follows:
• All D/I/O operations are disabled
• All three D/I/O ports are configured as D/I port
• All D/O latch register are undefined.(refer to Sec. 2.3.2)
Initialization must be performed before using these D/I/Os. The recommended
steps are as follows:
Step 1: Find address-mapping of OME-PIO/PISO cards (refer to Sec. 3.1)
Step 2: Enable all D/I/O operations (refer to Sec. 3.3.1)
Step 3: Configure the three ports (in CON3) to their expected D/I/O state &
send the initial value to all D/O ports (refer to Sec. 3.3.8)
Refer to DEMO1.C for demo program.

2.4
Interrupt Operation
All PC0, PC1, PC2 and PC3 can be used as an interrupt signal sources. Refer to
Sec. 2.1 for PC0/PC1/PC2/PC3 location. The interrupt of OME-PIO-D56/OMEPIO-D24 is level-trigger & Active_High. The interrupt signal can be programmed to
inverted or non-inverted state. The programming procedure is given as follows:
1. Make sure the initial level is High or Low
2. If the initial state is High Æ select the inverted signal (Sec. 3.3.6)
3. If the initial state is Low Æ select the non-inverted signal (Sec. 3.3.6)
4. Enable the INT function (Sec. 3.3.4)
5. If the interrupt signal is active Æ program will transfer into the interrupt
service routine Æ if INT signal is High now Æ select the inverted input
Æ if INT signal is Low now Æ select the non-inverted input
Refer to DEMO3.C & DEMO4.C for single interrupt source. Refer to
DEMO5.C for four interrupt sources.
If only one interrupt signal source is used, the interrupt service routine does not
have to identify the interrupt source. (Refer to DEMO3.C & DEMO4.C)
If there is more than one interrupt source, the interrupt service routine has to
identify the active signals via the following steps: (Refer to DEMO5.C)
1. Reads the new status of the interrupt signal source
2. Compares the new status with the old status to identify the active signals
3. If PC0 is active, service PC0 & non-inverter/inverted the PC0 signal
4. If PC1 is active, service PC1 & non-inverted/inverted the PC1 signal
5. If PC2 is active, service PC2 & non-inverted/inverted the PC2 signal
6. If PC3 is active, service PC3 & non-inverted/inverted the PC3 signal
7. Saves the new status to old status
Note: If the interrupt signal is too short, the new status may be the same as old
status. So the interrupt signal must be held active until the interrupt service
routine is executed. This hold time is different for different operating systems. It
can be as a short as micro-second or as a long as second. In general, 20ms is
enough for most operating systems.

The interrupt output signal of OME-PIO-D56/OME-PIO-D24, INT\ is
Level_trigger & Active_Low. If the INT\ generates a low pulse, the OME-PIOD56/OME-PIO-D24 will interrupt the PC only once. If the INT\ is fixed in low level,
the OME-PIO-D56/OME-PIO-D24 will interrupt the PC continuously.
INT_CHAN_0/1/2/3 must be controlled in a pulse type signals. It must be fixed in
low level state normally and generate a high pulse to interrupt the PC.
The priority of INT_CHAN_0/1/2/3 is the same. If all these four signals are active
at the same time, then INT\ will be active only one time. So the interrupt service
routine has to read the status of all interrupt channels for a multi-channel interrupt.
Refer to Sec. 2.4 for mare information.
DEMO5.C → for multi-channel interrupt source
If only one interrupt source is used, the interrupt service routine does not have to read
the status of interrupt source. The demo programs DEMO3.C and DEMO4.C are
designed for single-channel interrupt demo, as follows:
DEMO3.C → for INT_CHAN_0 only (PC0 initial low)
DEMO4.C → for INT_CHAN_0 only (PC0 initial high)

EN0 (1/2/3) = 1 → INT_CHAN_0(1/2/3) = enable

Sec.3.3.6)
INV0 (1/2/3) = 0 → INT_CHAN_0(1/2/3) = inverted state of PC0 (1/2/3)
INV0 (1/2/3) = 1 → INT_CHAN_0(1/2/3) = non-inverted state of PC0 (1/2/3)

Note: When the interrupt is active, the user program has to identify the active
signals. These signals may be active at the same time. The interrupt service
routine has to service all active signals at the same time.

3.2 The Assignment of I/O Address
The plug & play BIOS will assign the proper I/O address to the OMEPIO/PISO series card. If there is only one OME-PIO/PISO board, the user can
identify the board as card_0. If there are two PIO/PISO boards in the system, the
user will be very difficult to identify which board is card_0? The software driver can
support 16 boards max. Therefore the user can install 16 boards of PIO/PSIO series
in one PC system. How to find the card_0 & card_1?
The simplest way to identify which card is card_0 is to use wSlotBus &
wSlotDevice as follows :
1. Remove all OME-PIO-D56/OME-PIO-D24 from this PC
2. Install one OME-PIO-D56/OME-PIO-D24 into the PC’s PCI_slot1, run
PIO_PISO.EXE & record the wSlotBus1 & wSlotDevice1
3. Remove all OME-PIO-D56/OME-PIO-D24 from this PC
4. Install one OME-PIO-D56/D24 into the PC’s PCI_slot2, run PIO_PISO.EXE &
record the wSlotBus2 & wSlotDevice2
5. Repeat (3) & (4) for all PCI_slot?, record all wSlotBus? & wSlotDevice?
The records may be as follows:
PC’s PCI slot
wSlotBus
wSlotDevice
Slot_1
0
0x07
Slot_2
0
0x08
Slot_3
0
0x09
Slot_4
0
0x0A
Slot_5
1
0x0A
Slot_6
1
0x08
Slot_7
1
0x09
Slot_8
1
0x07
PCI-BRIDGE
The above procedure will record all wSlotBus? & wSlotDevice? in this PC. These
values will be mapped to this PC’s physical slot. This mapping will not be changed
for any PIO/PISO cards. So it can be used to identify the specified OME-PIO/PISO
card as follows:
Step 1: Record all wSlotBus? & wSlotDevice?
Step2: Use PIO_GetConfigAddressSpace(…) to get the specified card’s wSlotBus
& wSlotDevice
Step3: The user can identify the specified OME-PIO/PISO card if the compare
the wSlotBus & wSlotDevice in step2 to step1.

The I/O Address Map
The I/O address of OME-PIO/PISO series card is automatically
assigned by the main board ROM BIOS. The I/O address can also be reassigned by user. Users are strongly recommended to change the autoassigned I/O address. The plug & play BIOS will assign proper I/O
address to each OME-PIO/PISO series card very well. The I/O addresses
of OME-PIO-D56/OME-PIO-D24 are given as follows:
