PCI 703 User Manual Eagle Technology - Data Acquisition 1 1. Introduction The PCI703 series are 32-bit PCI bus architecture data acquisition boards. They are available in four models, the 16, 32 and 64 channels analog input board and the sample-and-hold version. The PCI703 contains digital input and output ports, onboard counters, a frequency generator, analog-in and analog-out sub-systems. The PCI703 is a multi-purpose analog board that can be used in many applications.

PCI 703 User Manual Eagle Technology - Data Acquisition 2 2. Installation This chapter describes how to install and configure the PCI703 for the first time. Minimal configuration is necessary; almost all settings are done through software. The PCI BIOS or operating system will take care of all resource assignments.
PCI 703 User Manual Eagle Technology - Data Acquisition Software Installation Windows 98/2000/ME Installing the Windows 98/2000 device driver is a very straightforward task. Because it is plug and play Windows will auto detect the PCI board as soon as it is installed. No setup is necessary. You simply have to supply Windows with a device driver. Wait until Windows detects the new hardware Select Next Eagle Technology © Copyright 2001-2004 – www.eagledaq.
PCI 703 User Manual Eagle Technology - Data Acquisition Select “Search for a suitable driver for my device…” and select next Make sure only “Specify a location” is selected and select next Eagle Technology © Copyright 2001-2004 – www.eagledaq.
PCI 703 User Manual Eagle Technology - Data Acquisition Select the browse button and search for the PCI703.inf file on the Eagle CD-Rom. The driver is normally located in the :\EDRE\DRIVERS \WDM \PCI703 directory. The PCI703/16/64 use the same driver. However the PCI703S has a different driver. Please sure that you use the appropriate driver for your board. Eagle Technology © Copyright 2001-2004 – www.eagledaq.
PCI 703 User Manual Eagle Technology - Data Acquisition Select next when found. Select next again. When done you might have to restart your computer. Post installation When done with the driver installation the device manager can be open to make sure the installation was a success. Eagle Technology © Copyright 2001-2004 – www.eagledaq.
PCI 703 User Manual Eagle Technology - Data Acquisition • • First make sure that the driver is working properly by opening the Device Manager. Check under the Eagle Data Acquisition list if your board is listed and working properly. See picture below. • • Clearly you can see that the PCI device is listed and working properly. Further open the control panel and then the EagleDAQ folder. This dialog should list all installed hardware. Verify your board’s properties on this dialog.
PCI 703 User Manual Eagle Technology - Data Acquisition Now the first part of your installation has been completed and ready to install the EDR Enhanced Software Development Kit. • Run edreapi.exe found on the Eagle CD-Rom and follow the on screen instructions Windows NT Windows NT does not require any special setup procedure. The Windows NT driver does not support plug and play. If Windows 2000 detects a new device simply install a default driver, or so called placeholder.

PCI 703 User Manual Eagle Technology - Data Acquisition 4 4. Programming Guide The PCI703 is supplied with a complete software development kit. EDR Enhanced (EDRE SDK) comes with drivers for many operating systems and a common application program interface (API). The API also serves as a hardware abstraction layer (HAL) between the control application and the hardware. The EDRE API makes it possible to write an application that can be used on all hardware with common sub-systems.
PCI 703 User Manual Eagle Technology - Data Acquisition Digital Inputs/Outputs The PCI703 has got 8 digital I/O lines and 10 multi I/O lines that can all be used for digital control purposes. The EDRE API supports auto direction configuration. By writing to or reading from a port, it is automatically configured as an output or input. A port is defined as a collection of simultaneous configurable entities. Thus in the case of the PCI703 each port is only 1 -bit wide.
PCI 703 User Manual Eagle Technology - Data Acquisition Counters The counter sub-system is supported by functions to Write, Configure and controlling the gate. There are 3 counters and 1 frequency generator. Only the first two counters and the frequency generator are available for the user. See the table below that shows the relation of the counters and their assigned numbers.
PCI 703 User Manual Gate Eagle Technology - Data Acquisition Table 4-2 Counter Configuration Controlling the counter gate A single call is necessary to setup/control a counter’s gate. This function call is invalid for the frequency generator (counter 2). Counter 2 does not have a gate. API-CALL Long EDRE_CTSoftGate(ulng Sn, ulng Ct, ulng Gate) The serial number, counter-number and gate are needed to control a counter’s gate. A return code will indicate if any errors occurred.
PCI 703 User Manual Eagle Technology - Data Acquisition Analog Output The PCI703-X/A version has got 2 DAC channels that support single write and waveform generation. The DAC subsystem uses the onboard counters for timing and a FIFO for data transfer. The two DAC channels are controlled independently from each other. The DAC subsystem is control via 3 functions: SingleWrite, Control and Configure. Writing to a DAC channel A single call is necessary to set a voltage on a DAC channel.

PCI 703 User Manual Eagle Technology - Data Acquisition Analog Input The PCI703 has got a very unique A/D subsystem and is fully configurable. Configuration includes dynamic range, gain, reference and differential or single ended. Each of these settings can be applied to an individual channel while scanning. Please not that although the PCI703 and PCI703S is similar in operation and uses the same functions, not all parameters apply to the PCI703S.

PCI 703 User Manual Eagle Technology - Data Acquisition Query Codes This chapter explains query codes and their functions relating to the PCI703 series. It will show examples of typical query codes that can make custom application allot easier to develop and tailor made for the PCI703 boards. Please note that all examples or pseudo code will show the API call and not the ActiveX call. Use the section below to translate between the two different implementations.
PCI 703 User Manual Eagle Technology - Data Acquisition How to check for available data To check for the number of samples available in the driver buffer use the query functions as below. PSEUDO BEGIN UI32 Sn=1000000001 /*32-bit unsigned integer - Serial Number*/ I32 Status /*32-bit integer*/ Status=EDRE_Query(Sn, ADUNREAD /*Code 109*/,0) If Status < 0 Then Error Print “Samples available = “ + Status PSEUDO END How to get the driver buffer size To get the driver buffer size, use the query below.
