Introduction

The seven jumper blocks on the PCI bus 12 bit data acquisition adapter must be configured correctly in accordance with the operating system you are using.

JP1 (Jumper 1)
Determines AD526 (gain control factor) is used.

JP2 (Jumper 2)

Determines to adjust LF398 input voltage offset.

JP3 (Jumper 3)

Determines to adjust SPT574( ADS574JP )input voltage offset.

JP4 (Jumper 4)

Determines A/D and voltage range.

JP5 (Jumper 5)

Determines unipolar or bipolar for A/D channel.

JP6 (Jumper 6)
Determines unipolar or bipolar for D/A channel 1.

JP7 (Jumper 7)
Determines unipolar or bipolar for D/A channel 2.

SW1 (Switch 1)

Identifies card number.

Configuration for Jumper

It is important to refer to the user manual to determine the correct configuration. Please contact your supplier if you have any difficulties with configuration.

Please refer to the following settings for each jumper block.



1. I/O Port Address

The plug and play features set I/O port address automatically, please refer the device manager of control panel to get base port address of this adapter.

2. Voltage Range
JP4 is used to select a range of A/D voltage from 0 to 10 volts or to a maximum voltage of 20 volts.  Shorting pin 1 and pin 2 will have a voltage range of 10 volts, while shorting pin 2 and pin 3 will have a voltage range of 20 volts.

3. Unipolar or bipolar

JP5 JP6, JP7

Selects unipolar/bipolar of A/D or D/A channels. JP5 is used to select unipolar or bipolar of A/D channel, JP6 is used to select unipolar or bipolar of D/A channel 1, and JP7 is used to select unipolar of bipolar of D/A channel 2. For JP5, shorting pin 1 and pin 2 selects bipolar setting, while shorting pin 2 and pin 3 selects a unipolar setting. For JP6 and JP7, shorting pin 1 and pin 2 selects bipolar setting, while shorting pin 3 and pin 4 selects a unipolar setting.

4. Input Mode for LF398

JP2

The JP2 is used to adjust input offset of LF398. Setting the jumper to pin 2 and pin 3 will ground the input value (0V), so the data that will be converted should also be 0.  This setting is used whenever we need to calibrate the VR1 variable resistors so that the minimum voltage will be attained.

Shorting jumper to pin 1 and pin 2 will make use of the channel inputs to be read and converted. It is the normal input mode.

5. Input Mode for SPT574

JP3

The JP3 is used to adjust input offset of SPT574. Setting the jumper to pin 2 and pin 3 will ground the input value (0V), so the data that will be converted should also be 0.  This setting is used whenever we need to calibrate the VR2 or VR4 variable resistors so that the minimum voltage will be attained.

Shorting jumper to pin 1 and pin 2 will make use of the channel inputs to be read and converted. It is the normal input mode.

6. Programmable Gain Control Factor (AD526)
The JP1 is used to select programmable gain control factor, when not short the jumper, it enable AD526, otherwise short the pin means no AD526 work (can not control gain control factor).

7. Card Identifier



The switch is used to identify card number, default setting is card 15, and there are two methods to set the card number:

a. PnP mode
Just plug in PCI bus 12 bit data acquistion adapter into PCI slot, the PCI BIOS will allocate I/O address to each adapter automatically and assign card number start from 0 to each adapter. You may set any card number at PnP mode, and you need use software tools to distinguish port id. Almost all of the operating systems run at PnP mode..


b. manual mode
Set card number by card identifier switch, the PCI BIOS will assign pre-allocated I/O address to each adapter. Please set different card number to each adapter (do not duplicate card number setting).

The card number starts from 0 to 15.

I/O Address Specification

The I/O address specification are shown in the following:

For READ input

port + 0: input 12 bit A/D data.
port + 2: clear the interrupt signal that generated from the adapter.
port + 6: 16 bit digital signal input.
port + 8: counter 0 I/O buffer (8254 IC).
port + 9: counter 1 I/O buffer (8254 IC).
port + A: counter 2 I/O buffer (8254 IC).
port + B: counter control register (8254 IC).

For WRITE output

port + 0: select A/D channel number, enable/disable the selected channel, select IRQ and select control method.
port + 2: 12 bit D/A channel 1.
port + 4: 12 bit D/A channel 2.
port + 6: 16 bit digital output.
port + 8: counter 0 I/O buffer (8254 IC).
port + 9: counter 1 I/O buffer (8254 IC).
port + A: counter 2 I/O buffer (8254 IC).
port + B: counter control register (8254 IC).

Before adjust your AD/DA voltage offset, please run PCIADV03.EXE program under MS/DOS, then select calibration function as follows.

1. D/A Calibration
VR5 is used to adjust the D/A channel 1 offset voltage, and VR6 is used to adjust the D/A channel 2 offset voltage.
To adjust D/A channel 1 offset voltage, please follow the step shown in the below:

Step 1: short pin 1 and pin 2 of JP5, then adjust VR5 to let J1-15 output range from -10V to 10V.
Step 2: short pin 3 and pin 4 of JP5, then adjust VR5 to let J1-15 output range from 0V to 10V.

To adjust D/A channel 2 offset voltage, please follow the step shown in the below:

Step 1: short pin 1 and pin 2 of JP7, then adjust VR6 to let J1-03 output range from íV10V to 10V.
Step 2: short pin 3 and pin 4 of JP7, then adjust VR6 to let J1-03 output range from 0V to 10V.

2. A/D Calibration

Step 1: short pin 2 and pin 3 of JP2, pin 2 and pin 3 of JP3, pin 1 and pin 2 of JP4, and pin 1 and pin 2 of JP5, then adjust VR3 to let the output value is 2047.
Step 2: short pin 2 and pin 3 of JP2, pin 2 and pin 3 of JP3, pin 1 and pin 2 of JP4, pin 2 and pin 3 of JP5, then adjust VR2 to let the output value is 0.
Step 3: short pin 2 and pin 3 of JP2, pin 1 and pin 2 of JP3, pin 1 and pin 2 of JP4, and pin 1 and pin 2 of JP5, then adjust VR1 to let the output value is 2047.
Step 4: short pin 1 and pin 2 of JP2, pin 1 and pin 2 of JP3, pin 1 and pin 2 of JP4, and pin 2 and pin 3 of JP5, then input voltage from each A/D channel to check whether input voltage is equal to output voltage. In this step, please adjust VR4. The A/D channel is defined from J1-4 to J1-11 and J1-16 to J1-23.
You may repeat Step 1 to Step 4 if necessary.

Diagnostic Test

The PCIADV03.EXE also provides some diagnostic test functions:

1.
DIO loopback test
2.
DIO output test
3.
DIO input test
4.
A/D and D/A loopback test
Please short pint 1 and pin 2 of JP5, pin 2 and pin 3 of JP4, pin 1 and pin 2 of P3, pin 1 and pin 2 of JP2, and pin 1 and pin 2 of JP1, also short D/A channel (J1-15) to A/D input channel, then check whether the error value is less than 20.
