INTRODUCTION
The PIO-DA16, PIO-DA8 and PIO-DA4 are multi-channel D/A boards for the
PCI bus for IBM or compatible PC.
The 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 improves several drawbacks of the conventional D/A
boards. For examples: 1. Jumperless 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. It can be found in regular
PC or Industrial PC.

2.3
Interrupt Operation
There are two interrupt sources in 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.
2.
3.
4.
5.
Read the new status of all interrupt signal source
Compare the new status with old status to identify the active signals
If INT0 is active, service it
If INT1 is active, service it
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 can not 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 all O.S.

INT_CHAN_0
Level_trigger
(to PCI slot)
INT_CHAN_1
initial_low
active_high
The interrupt output signal of PIO-DA16/8/4, INT\, is Level-Trigger &
Active_Low. If the INT\ generate a low_pulse, the PIO-DA16/8/4 will interrupt the
PC once a time. If INT\ is fixed in low_level, the 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
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 and 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)

Inverted/Noninverted
select
(INV0/1)
Enable/Disable select
(EN0/1)
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 generated 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
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
As above discussion, if the INT\ fixed in low level state, the PIO-DA16/8/4 will
interrupt the PC continuous. So interrupt service routine should use INV0/1 to
invert/non-invert the INT0/1 to generate high_pulse (Refer to next section)

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;
outportb(wBase+0x2a,0);
/* initial state for INT0
*/
/* select the inverted INT0 */
void interrupt irq_service()

Refer to DEMO5.C for source program. All of these falling-edge & rising-edge can

Note: when the interrupt is active, the user program has to identify the active

2.6
D/A Convert Operation
The D/A converters on PIO-DA16/8/4 have 14 bits 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 PIODA16/8/4 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 values MaxI[n] and MinI[n]
(stored to on board EEPROM). MaxI[n] mapping to accurate 20mA and MinI[n]
mapping to accurate 0mA.

No VR & No Jumper Design
In the conventional 12-bit D/A board, for example A-626/A-628, there are many
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 handled by human hand. It is not a happy job for people
to calibrate these D/A boards.
When we design the PIO-DA/16/8/4, we try to remove all these terrible VRs and
jumpers but still maintain the same precision and performance. In the long run, we
select a 14-bit D/A converter and adapt the software calibration to provide at least the
same performance & precision as A-626/A-628 as follows:

hardware.
The Precision is at least the same as 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 PIO-DA16/8/4.
The I-7000 series is a set of precision remote control modules. The I-7017 is 8channel 16-bit precision A/D module (24-bit sigma-delta A/D converter), we use two
I-7017 for voltage output calibration and another two 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 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 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 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 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

User Software Calibration
User can perform calibration himself with a voltage meter and a current meter.
Step1: Run DEMO12.EXE
Step2: Select card number (PIO-DA16/PIO-DA8/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 step4 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 PIO/PISO series
card. If there is only one 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 ?
It is difficult to find the card NO. The simplest way to identify which card
is card_0 is to use wSlotBus & wSlotDevice as following:
1. Remove all PIO-DA16/8/4 from this PC
2. Install one PIO-DA16/8/4 into the PC’s PCI_slot1, run PIO_PISO.EXE &
record the wSlotBus1 & wSlotDevice1
3. Remove all PIO-DA16/8/4 from this PC
4. Install one 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
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 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 PIO/PISO card if he compare the
wSlotBus & wSlotDevice in step2 to step1.

3.3
The I/O Address Map
The I/O addresses of 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 not to change the I/O address by user.
The plug & play BIOS will assign proper I/O address to each PIO/PISO
series card very well. The I/O address list of PIO-DA16/8/4 is given as
follows:
