PCI30FG User Manual 1 Introduction The PCI30FG series are 32-bit bit PCI bus architecture data acquisition boards. They are available in two basic models, the G and F series. They can samples at 100kHz or 330kHz respectively. Addition to analog input, they also have analog output, digital input/output and counter-timer capabilities. For this reason the PCI30FG is an excellent all purpose data acquisition device with extensive analog input capabilities.

PCI30FG User Manual 2 Installation This chapter describes how to install and configure the PCI30FG for the first time. Minimal configuration is necessary; almost all settings are done through software. The PCI BIOS will assign an I/O base address and interrupt level. Package PCI30FG package will contain the following: • PCI30FG PCI board • EDR Enhanced Software Development Kit CD-Rom Hardware Installation This section will describe how to install your PCI30FG into your computer.
PCI30FG User Manual Software Installation Windows 98 Installing the Windows 98 device driver is a very straightforward task. Because it is plug and play Windows will detect the PCI30FG as soon as it is installed. No setup is necessary. You simply only have to supply Windows with a device driver.

PCI30FG User Manual Figure 2-4 Add New Hardware Wizard Step4 Windows should have detected the proper driver and ready to install it. Select Next to proceed. Figure 2-5 Add New Hardware Wizard Step5 Click on the finish button to complete the installation. Click Yes to restart your computer.
PCI30FG User Manual Figure 2-6 Restart Your Computer Post installation After your installation was complete there is a few steps that can be followed to check that your installation was successful. • • First make sure that the driver is working properly by opening the system folder in the control panel. Check under the system device list if your board is listed and working properly. See picture below. Figure 2-7 System Properties • Clearly you can see that the PCI36C is listed and working properly.
PCI30FG User Manual • 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. See picture below Figure 2-8 EagleDAQ Now the first part of your installation has been completed and ready to install the EDR Enhanced Software Development Kit. • Run setup.
PCI30FG User Manual Configuration Only the PCI30Gx series allows one manual setting. The PCI30Gx series has one jumper, LK1, to change the voltage span. The figure below shows the two different jumper settings. Figure 2-9 A/D Span Jumper Accessories The PCI30FG does have a wide variety of accessories that it can be connected too. See chapter on accessories.
PCI30FG User Manual 3 Interconnections The PCI30FG is designed so that there is a connector for analog signals and digital signals. The analog connector is on the bracket attached to the board and the other a connector on the PCB internal to the PC. External Connectors The PCI30FG does have two connectors, a SCSI-II-50 female centronics and an IDC40 male. The ICD40M can also be extended to the computer casing by making use of an extender cable and bracket that is supplied with the PCI30FG package.

PCI30FG User Manual Signal Definitions This sections deal with all the signals abbreviations.
PCI30FG User Manual CH0 V0 V15 CH15 AGND Figure 3-1 Single ended analog input Differential Inputs In differential input mode two multiplexer switches per channel are used. The A/D converter measures the difference in potential between the two channels. Channels are paired to form a single differential input. Channel 0 and channel 8 is used as channel 0, channels 1 and 9 etc. To connect see diagram below. It is also very important to know that each return connection must be referenced to analog ground.
PCI30FG User Manual In differential mode, all signal inputs to the PCI30FG must be referred to ground. This can be done by connecting a 1 to 10 kΣ Σ resistor from the low end of each input to ground. Analog Output The analog outputs come with sense lines and it is important to make sure that they are connected to the correct channel. If left unconnected the output will simple float at +10V or –10V. The analog output range is ±10V and is fully software configurable.
PCI30FG User Manual 4 Programming Guide The PCI30FG 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 make it possible to write one application that can be used on all hardware with common sub-systems.
PCI30FG User Manual Digital Inputs/Outputs The PCI30FG has 24 digital I/O lines, configured as 3 x 8-bit ports. 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 PCI30FG each port is only 8-bits wide. Reading the Digital Inputs A single call is necessary to read a digital I/O port.
PCI30FG User Manual Counters The counter sub-system is supported by functions to Write, Read and Configure. There are 4 counters that are available to the user and are compatible with the industry standard 8254 counter-timer. The table below shows all counters and their assigned function on the board. Please note that only some are available for the user. The 8254 datasheet has more information on the counter-timer modes.
PCI30FG User Manual Configuring a counter A single call is necessary to configure a counter. An external clock must clock the first three counters, but the internal 8MHz clock clocks the fourth counter. API-CALL Long EDRE_CTConfig(ulng Sn, ulng Ct, ulng Mode, ulng Type, ulng ClkSrc, ulng GateSrc) The serial number, counter-number, mode, type, clock source and gate source is needed to specify a counter’s configuration. A return code will indicate if any errors occurred. ACTIVEX CALL Long EDRECTX.
PCI30FG User Manual Analog Output The PCI30FG-A version has 4 x 12-bit DAC channels that support single write. Writing to a DAC channel A single call is necessary to set a voltage on a DAC channel. API-CALL Long EDRE_DAWrite (ulng Sn, ulng Channel, long uVoltage) The serial number, DAC channel and micro-voltage is needed to set a DAC channel’s voltage. A return code will indicate if any errors occurred. ACTIVEX CALL Long EDREDAX.
PCI30FG User Manual Analog Input The PCI30FG’s ADC subsystem is fully configurable and supports single channel reading and out scanning. While scanning a channel list and gain list can be provided. Channels are scanned in the same sequence provided in the channel list. Reading a single voltage from a channel To read a single ADC channel you need to know the voltage range and gain.

PCI30FG User Manual WARNING!! In normal sampling mode channels are sampled sequentially according to the given channels list. The time spacing between each channel is the same as the frequency in normal mode. The maximum frequency is the same as the maximum speed of the board. In burst mode the all channels in the channel list is converted as fast as possible (depends on the A/D converter speed) every period. The period is the same as the sampling frequency.

PCI30FG User Manual 5 Calibration This chapter contains information to calibrate the A/D and D/A sub-systems of the PCI30FG. The PCI30FG is calibrated during the manufacturing test and therefore does not require recalibration under normal conditions. However under extreme conditions or to optimize accuracy, the board needs to be recalibrated. Allow the host PC and the board to warm up for at least one hour before calibration. Requirements 1. Precision voltage source.
PCI30FG User Manual The program runs under dos and make sure that you do not run it in a Windows command box or on Windows NT. Follow the on screen instructions or the directions in the calibration section. Connection Figure 7.1 shows the connection diagram for calibrating your PCI30FG. It is very important that channels that are not used be grounded to analog ground.
PCI30FG User Manual A/D Calibrating Procedure Calibrating the PCI30Gx series Bipolar Mode 1. Adjust A/D for maximum gain (ie. 1000) and apply 0.00mV to channel 1. All other channels must be connected to analog ground. Adjust VR1, the instrumentation amplifier offset pot, for 800H. 2. Set A/D for a gain of 1 and apply (-FS+2LSB) to channel 1 (ie.-4.
