1. INTRODUCTION
The OME-PIO-DA16, OME-PIO-DA8 and OME-PIO-DA4 are multi-channel
D/A boards for the PCI bus for IBM or compatible PC.
The OME-PIO-DA16/8/4 offers 16/8/4 channels double-buffered analog output.
The output range may be configured in different ranges: ±10V, ±5V, 0~10V, 0~5V
voltage output or 4~20mA, 0~20mA current loop sink.
The innovative design eliminates several drawbacks of the conventional D/A
boards. For examples: 1. designed without jumpers and without trim-pot. 2. The
calibration is performed under software control eliminating manual trim-pot
adjustments. The calibration data is stored in EEPROM. 3. Each channel can be
selected as voltage or current output. 4. High channel count output can be
implemented in half size.
Note: This card need ±12V power supply (usually found in PC).

Page 11
2.3 Interrupt Operation
There are two interrupt sources in OME-PIO-DA16/8/4. These two signals are
named as INT0 and INT1.Their signal sources are given as follows:
INT0: 8254 counter0 output (Refer to Sec. 2.2)
INT1: 8254 counter2 output (Refer to Sec. 2.2)
If only one interrupt signal source is used, the interrupt service routine doesn’t have
to identify the interrupt source. Refer to DEMO3.C and DEMO4.C for more
information.
If there are more than one interrupt source, the interrupt service routine has to
identify the active signals as follows: (Refer to DEMO5.C and DEMO6.C)
1. Read the new status of all interrupt signal source
2. Compare the new status with old status to identify the active signals
3. If INT0 is active, service it
4. If INT1 is active, service it
5. Save the new status to old status
Note: If the interrupt signal is too short, the new status may be as same as old
status. In that condition the interrupt service routine cannot identify which
interrupt source is active. So the interrupt signal must be hold_active long
enough until the interrupt service routine is executed. This hold_time is different
for different O.S. The hold_time can be as short as micro-second or as long as
second. In general, 20mS is enough for most operating systems.

OME-PIO-DA16/8/4
INT\
Level_trigger
INT_CHAN_0
(to PCI slot)
The interrupt output signal of OME-PIO-DA16/8/4, INT\, is Level-Trigger &
Active_Low. If the INT\ generate a low_pulse, the OME-PIO-DA16/8/4 will
interrupt the PC once a time. If INT\ is fixed in low_level, the OME-PIO-DA16/8/4
will interrupt the PC continuously. So the INT_CHAN_0/1 must be controlled in a
pules_type signals. They must be fixed in low_level statue normally and
generated a high_pulse to interrupt the PC.
The priority of INT_CHAN_0/1 is the same. If all these two signals are active at
the same time, then INT\ will be active only once a time. So the interrupt service
routine has to read the status of all interrupt channels for multi channels interrupt.
Refer to Sec. 2.3 for more information.
DEMO5.C → for INT_CHAN_0 & INT_CHAN_1
INT_CHAN_1
initial_low
active_high
If only one interrupt source is used, the interrupt service routine doesn’t have to
read the status of interrupt source. The demo programs DEMO3.C - DEMO4.C are
designed for single-channel interrupt demo as follows:
DEMO3.C → for INT_CHAN_1 only (initial high)
DEMO4.C → for INT_CHAN_1 only (initial low)

Page 13
2.3.2 INT_CHAN_0/1
INT_CHAN_0/1
The architecture of INT_CHAN_0 and INT_CHAN_1 is the same as above figure.
The only difference between INT0 and INT1 is that INT_CHAN_0 signal source from
8254 counter0 output and INT_CHAN_1 signal source from 8254 counter2 output.
The INT_CHAN_0/1 must be fixed in low level state normally and generate a
high_pulse to interrupt the PC.
The EN0/1 can be used to enable/disable the INT_CHAN_0/1 as follows: (Refer to
INT0/1
Inverted/Noninverted
select
(INV0/1)
Enable/Disable select
(EN0/1)
Sec.3.3.4)
EN0/1 = 0 → INT_CHAN_0/1 = disable
EN0/1 = 1 → INT_CHAN_0/1 = enable
The INV0/1 can be used to invert/non-invert the INT0/1 as follows: (Refer to
Sec.3.3.6)
INV0/1 = 0 → INT_CHAN_0/1 = inverted state of INT0/1
INV0/1 = 1 → INT_CHAN_0/1 = non-inverted state of INT0/1
If the INT\ fixed in low level state, the OME-PIO-DA16/8/4 will interrupt the
PC continuously. So interrupt service routine should use INV0/1 to invert/non-
invert the INT0/1 to generate high_pulse (Refer to next section)

Page 14
2.3.3 Initial_high, active_low Interrupt source
If the INT0 (8254 counter0 output) is an initial_high, active_low signal
(depend on 8254 counter mode), the interrupt service routine should use INV0 to
invert/ non-invert the INT0 for high_pulse generation as follows: (Refer to DEMO3.C)
Initial set:
now_int_state=1; /* initial state for INT0 */
outportb(wBase+0x2a,0); /* select the inverted INT0 */
void interrupt irq_service()
{

Assume: INT0 is initial Low, active High,
INT1 is initial High, active Low
as follows:
INT0
INT1
INT0 & INT1
are active at
the same time
INT0 & INT1
are return to
normal at the
same time
INT1 is return
to normal
INT1 is active
Refer to DEMO5.C for source program. All of these falling-edge & rising-edge can
be detected by DEMO5.C.
Note: when the interrupt is active, the user program has to identify the active
signals. These signals may be active at the same time. So the interrupt service
routine has to service all active signals at the same time.

2.6 D/A Convert Operation
The D/A converters on OME-PIO-DA16/8/4 have 14 bits of resolution, so the
digital data value range from 0x0000 to 0x3fff. And the hardware is designed to
output voltage range from -10.1~+10.1 as follows:
0x0000 → about –10.1 volt
0x3FFF → about +10.1 volt
In the conventional design, there will be some VRs to adjust to let 0x0000=-10.0V
& 0x3fff=+10.0V for voltage output. Also these VRs have to be adjusted to let
0x1fff=0mA & 0x3fff=20mA for current output. In the conventional design, these
VRs are common for voltage/current output. So the user has to perform calibration
when change from voltage to current. Also If these VRs are changed, the user has to
perform calibration again. This procedure is complex & heavy load. The OME-PIO-
DA16/8/4 use software calibration to replace this complex procedure as following:
• for each voltage output channel we find two hex value MaxV[n] and MinV[n]
(stored to on board EEPROM). MaxV[n] mapping to accurate +10V and MinV[n]
mapping to accurate –10V.
• For each current output channel we also find two hex value MaxI[n] and MinI[n]
(stored to on board EEPROM). MaxI[n] mapping to accurate 20mA and MinI[n]
mapping to accurate 0mA.

15 133 16295 8175 15965
If the user want to send Vout(volt) to channel n, the calibrated hex value, DaValue,
sent to D/A converter is give as follows:
DeltaV[n]=20.0/(MaxV[n]–MinV[n]); /* DeltaV[n]=volt per count at channel_n */
DaValue=(Vout+10.0)/DeltaV[n]+MinV[n]; /* DaValue=Hex value send to D/A */
pio_da16_da(n,DaValue); /* send DaValue to channel n */
If the user want to send Iout(mA) to channel n, the calibrated hex value, DaValue,
sent to D/A converter is give as follows: (Refer to DEMO9.C)
DeltaI[n]=20.0/(MaxI[n]–MinI[n]); /* DeltaI[n]=mA per count at channel_n */
DaValue=Iout/DeltaI[n]+MinI[n]; /* DaValue=Hex value send to D/A */
pio_da16_da(n,DaValue); /* send DaValue to channel n */

2.6.8 No VR & No Jumper Design
In the conventional 12-bit D/A board, for example OME-A-626/A-628, there are
jumpers for the following functions:
(1) select the reference voltage (internal –10/-5/or external)
(2) select unipolar/bipolar (0-10V or ±10V)
(3) select different output range (0-10V or 0-5V)
And there are many VRs for the following functions:
(1) voltage output offset adjustment
(2) voltage output full-scale adjustment
(3) current output offset adjustment
(4) current output full-scale adjustment
There are so many VRs and jumpers, this make the QC and re-calibration very
difficult. Every step must be performed manually making is difficult to calibrate these
D/A boards.
The design of the OME-PIO-DA/16/8/4 removed all these VRs and jumpers but
still maintain the same precision and performance. There is a 14-bit D/A converter
and software calibration to provide at least the same performance & precision as
OME-A-626/A-628 as follows:
Configuration Equivalent Bit Resolution
-10V ~ +10V 14 bit 1.22mV
0V ~ 10V 13 bit 1.22mV
-5V ~ +5V 13 bit 1.22mV
0V ~ +5V 12 bit 1.22mV
0mA ~ 20mA 13 bit 2.70uA
4mA ~ 20mA 13 bit 2.70uA
• All these VRs and jumpers are removed.
• All calibrations can be done by software.
• All channel configurations can be selected by software, no need to change any
hardware.
• The Precision is at least the same as OME-A-626/A628.
• All these 16 channels can be configured and used in the different configuration at
the same time. (For example, channel_0=±10V, channel_1=4~20mA,
channel_2=0~5V, …).
• All these features can be implemented in a small, compact, reliable and half-size
PCB.

2.6.9 Factory Software Calibration
It is recommended to use a 16-bit A/D card to calibration the OME-PIO-
DA16/8/4. The OME-I-7000 series is a set of precision remote control modules. The
I-7017 is 8-channel 16-bit precision A/D module (24-bit sigma-delta A/D converter),
we use two OME-I-7017 for voltage output calibration and another two OME-I-7017
for current output calibration.
The steps for channel_n voltage calibration are given as follows:
Step 1: DaValue=0
Step 2: send DaValue to OME-PIO-DA16/8/4 channel_n
Step 3: measure the I-7017 channel_n,
If this value is just >= -10V, than goto step 5
Step 4: incrememt DaValue, goto step 2
Step 5: MinV[n]=DaValue-1
Step 6: DaValue=0x3fff
Step 7: send DaValue to OME-PIO-DA16/8/4 channel_n
Step 8: measure the I-7017 channel_n,
If this value is just >= +10V, than goto step 10
Step 9: increment DaValue, goto step 7
Step 10: MaxV[n]=DaValue
Note: MinV[n] & MaxV[n] are discribed in Sec.2.6
The steps for channel_n current calibration are given as follows:
Step 1: DaValue=0x1fff
Step 2: send DaValue to OME-PIO-DA16/8/4 channel_n
Step 3: measure the I-7017 channel_n,
If this value is just >= 0mA, than goto step 5
Step 4: incrememt DaValue, goto step 2
Step 5: MinI[n]=DaValue-1
Step 6: DaValue=0x3fff
Step 7: send DaValue to OME-PIO-DA16/8/4 channel_n
Step 8: measure the I-7017 channel_n,
If this value is just >= 20mA, than goto step 10
Step 9: increment DaValue, goto step 7
Step 10: MaxI[n]=DaValue
Note: MinI[n] & MaxI[n] are discribed in Sec.2.6

2.6.10 User Software Calibration
User can perform calibration with a voltage meter and a current meter.
Step1: Run DEMO12.EXE
Step2: Select card number (OME-PIO-DA16/OME-PIO-DA8/OME-PIO-DA4) that
you want to calibrate
Step3: Select which item (MinV[n]/MaxV[n]/MinI[n]/MaxI[n]) that you want to
calibrate
Step4: To measure the analog output by voltage meter or current meter and decide to
increment or decrement DaValue. The DaValue will send to D/A converter at
once. By the measured result user can find the proper value of DaValue that
mapping to accurate output value.
Step5: Repeat step 4 for each channel
After this procedure, the new data of MinV[n]/MaxV[n]/MinI[n]/MaxI[n] will be
stored to on board EEPROM.
User can run DEMO10.EXE to back-up the old calibration data to
“A:\DA16.DAT” before new calibration.
If something error during the new calibration, user can run DEMO11.EXE to
download data from “A:\DA16.DAT” to EEPROM.
Note :
DEMO10.EXE → save old calibration data
DEMO11.EXE → download old calibration data
DEMO12.EXE → perform new calibration

3.2 The Assignment of I/O Address
The plug & play BIOS will assign the proper I/O address to the OME-
PIO/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 OME-PIO/PISO boards in the system,
it will be difficult to identify which board is card_0? The software driver can support
16 boards max. Therefore the user can install 16 boards of OME-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 following:
1. Remove all OME-PIO-DA16/8/4 from this PC
2. Install one OME-PIO-DA16/8/4 into the PC’s PCI_slot1, run
PIO_PISO.EXE & record the wSlotBus1 & wSlotDevice1
3. Remove all OME-PIO-DA16/8/4 from this PC
4. Install one OME-PIO-DA16/8/4 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
PCI-BRIDGE
Slot_5 1 0x0A
Slot_6 1 0x08
Slot_7 1 0x09
Slot_8 1 0x07
The above procedure will record all wSlotBus? & wSlotDevice? in the 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 PIO/PISO card as
following:
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 you compare
the wSlotBus & wSlotDevice in step2 to step1.

3.3 The I/O Address Map
The I/O addresses of OME-PIO/PISO series card are automatically
assigned by the main board ROM BIOS. The I/O address can also be re-
assigned by user. It is strongly recommended to the user to not change the
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 the
OME-PIO-DA16/8/4 cards are given as follows:
Address Read Write
wBase+0 RESET\ control register Same
wBase+2 Aux control register Same
