1. Installation Guide

1) Copy files

Download the drivers in a zip file from http://mr-roboto.me.uiuc.edu/evps/archive/codes/pci_w2k.zip. 

2) Fine tunes

(1) How to change the input option of PCI-DAS1200 from 8 differential channels into 16 single-ended channels?

(2) How to change the range of Sensor Signal (+/-Xss V) and of Conditioned Signal(+/- Xcs V)?
(when different signal conditioners are used.)

A "Block Diagram" in pure text:
(Sensor Signal +/-10V )-->[Signal Conditioner]-->(Conditioned Signal +/-5V)-->[PCI-DAS1200,ADC]
-->(Digital Value 0~0xFFF)-->[Function PCI12_adcInputToVoltage]--> (Voltage Result +/-10V)

The ADC input option should be +/-5(V) for the conditioned signal range:
File: pci12tad.h, line 106, "PCI1200_ADC_SWCONVERT_DIFF5", use Xcs of the conditioned signal.

However, the represented voltage range should be that of the sensor signal (+/-10V) instead the conditioned signal(+/-5V):
File: pci1200.h, line50-51
#define PCI1200_ADC_MIN_VOLT (-10.0)            //-Xss, the minimum value of the Sensor Signal range
#define PCI1200_ADC_MAX_VOLT (+10.0)            //Xss, the maximum value of the Sensor Signal range

2. Overview of Files

3. Notes:

Steps to write a driver

1. Prepare pci*.c, pci*.h, pci*pp.h, pci*da.h, pci*ad.h, pci*di.h, pci*do.h
    - use the "scanbus.exe" under RTX DSK\samples\ to find out the VENDOR_ID, DEVICE_ID and modify the corresponding Plug-And-Play hearder file pci*pp.h.
2. Use the existent block as a template to add blocks for the new board in winlib.mdl. Rename the S-function name.
3. Compile the pci*.c into .dll for the S-Function;
4. Prepare target files pci*da.tlc, pci*ad.tlc, pci*di.tlc, pci*do.tlc for the RTW build process.

About Specifications

- PCI-DAS1200: max 330kHz is for single channel (T_convert = 3ms). for 16 channels, max f_sample ~= 20 kHz

Tricks

- How to add the "tab completion" feature to the command window in W2k? 
Run "regedit'; go to "HKEY_Local_Machine\SOFTWARE\Microsoft\Command Processor\", change the "CompletionChar" to "9".
