2 Installation This chapter describes how to install the PCI-6308. Please follow the following steps to install the PCI-6308 family of products. • Check what you have (section 2.1) • Unpacking (section 2.2) • Check the PCB and jumper location (section 2.3) • Install the hardware and setup and jumpers (section 2.4, 2.7) • Install the software drivers and run utility to test (section 2.5) • Cabling with external devices (section 2.6, 2.8) 2.
2.2 Unpacking The PCI-6308 series card contains electro-static sensitive components that can be easily be damaged by static electricity. Therefore, the card should be handled on a grounded anti-static mat. The operator should be wearing an anti-static wristband, grounded at the same point as the anti-static mat. Inspect the card module carton for obvious damages. Shipping and handling may cause damage to your module. Be sure there are no shipping and handling damages on the modules carton before continuing.

2.4 Hardware Installation Outline 2.4.1 Hardware configuration The PCI cards (or CompactPCI cards) are equipped with plug and play PCI controllers, it can request base addresses and interrupts according to the PCI standard. The system BIOS will assign the system resources based on the PCI cards’ configuration registers and system parameters (which are set by the system BIOS). Interrupt assignment and memory usage (I/O port locations) can only be assigned by the system BIOS.
2.5 Device Installation for Windows Systems Once Windows 95/98/2000 has started, the Plug and Play functions of the Windows system will find and locate the new NuDAQ/NuIPC card. If this is the first time a NuDAQ/NuIPC card is installed in your Windows system, you will be prompted to input the device information source. Please refer to the “Software Installation Guide” for installation procedures of the device drivers. 2.

3 Registers The descriptions of the registers and structure of the PCI-6308 Series are outlined in this chapter. The information in this chapter will assist programmers, who wish to handle the card with low-level programs. In addition, the low level programming syntax is introduced. This information can help beginners to operate the 743X in the shortest possible time. 3.1 PCI PnP Registers This PCI card functions as a 32-bit PCI target device to any master on the PCI bus.
3.2 I/O Address Map Most of the PCI-6308 registers are 16 bits. Users can access these registers using 16-bit I/O instructions. The following table shows the registers map, including descriptions and their offset addresses relative to the base address.
3.4 Digital Output Register D0~D3 is the digital output signal written to the output channel. D4~D7 don’t care. Address: BASE + 40(hex) Attribute: write only Data Format: Bit BASE+20 7 X 6 X 5 X 4 X 3 DO3 2 DO2 1 DO1 0 DO0 1 DO1 0 DO0 3.5 Digital Input Ports D4~D7 is the digital input signal from CN1. D0~D3 is read back signal from the digital output channel.
4 Operation Theory In this chapter, the detail operation theory of the PCI-6308V and PCI-6308A is described. Before programming or applying the PCI-6308 card to your application, please go through this chapter to understand the features first. 4.1 Voltage Output There are 8 voltage output channels for PCI-6308V and 6308A. For voltage output operation, you have to understand: 1. 2. 4.1.1 How to set the voltage output range. The DA data format.
4.1.2 DA data format The DA data format is a 12-bit unsigned value for all channels, that is, the value is in binary format. The digital value range from 0(0X000) to +4095(0xFFF) corresponds to the full span of the output range, which is set by the jumpers. Table 4.1 shows the relationship between the digital value and the analog output voltage. If the application requires a smaller voltage range, the PCI-6308 can still be applied.
4.2 Analog Output Status Register The DAC uses a series bus architecture hence there is a delay in the output of the digital value. The data transfer time for every DA data write takes 16µs, therefore the software driver must wait for 16µs before sending another set of data to any analog output port. While the DA value is sending, the Data_Send bit is ‘H’. The software driver should check this bit before writing any data to the output port. This register is read only. Base 0x00 D16~D1 X D0 Data_Send 4.
Mode 0 1 2 3 Input Voltage Range 0~10V 0~10V -0~10V Output Current Range 0~20 mA 5~25 mA -4~20 mA 4.4 Isolated Digital Output The isolated digital output circuits have the following characteristics. The output is of an open collector type. The isolation voltage between the isolated output and the host power signals is 2500 Vrms. Don (n=1~4) Photo Coupler GND 4.5 Isolated Digital Input The isolated digital input circuits have the following characteristics.
5 C/C++ Library This chapter describes the software library for operating this card. Only the functions in the DOS library and Windows 95 DLL are described. Please refer to the PCIS-DASK function reference manual, which is included in the ADLINK CD, for descriptions of Windows 98/NT/2000 DLL functions. Function prototypes and useful constants are defined in the header files of the LIB directory (DOS) and INCLUDE directory (Windows 95). For Windows 95 DLL, the developing environment can be Visual Basic 4.
5.2 Programming Guide 5.2.1 Naming Convention There are 7 function calls provided by the C Language Library. All the functions of the PCI-6308 are covered in this library. The functions of the PCI-6308 software driver use full-names to represent the functions' real meaning. The naming convention rules are: In DOS Environment: _{hardware_model}_{action_name}. e.g. _6308_Initial(). All functions in the PCI-6308 driver start with 6308 as {hardware_model} and can be used by both the PCI-6308V and PCI-6308A.
5.3 _6308_Initial @ Description This function is used to initialize the PCI 6308. Every PCI_6308 has to be initialized by this function before calling other functions.
5.5 _6308_DA @ Description This function is used to write data to the D/A converters. There are 8 Digital-to-Analog conversion channels on the PCI-6308. The resolution of each channel is 12 bits unsign; i.e. the digital value range from 0 (0x000) to +4095 (0xFFF). Please refer to section 4.1.2 for details of the DA data format.
5.6 _6308_DA_0_3 @Description This function is used to simultaneously write data to the D/A converters of channel 0 to channel 3. The resolution of each channel is 12 bits unsign; i.e. the digital value range from 0 to 4095. Please refer to section 4.1.2 for details of the DA data format.
5.7 _6308_DA_4_7 @Description This function is used to simultaneously write data to the D/A converters of channel 4 to channel 7. The resolution of each channel is 12 bits unsign; i.e. the digital value range from 0 to 4095. Please refer to section 4.1.2 for details of the DA data format.
5.8 _6308_Get_DA_Status @ Description This function is used to check the DA data sending status. Because the data transfer time for every DA data takes 16.0 µs, the software driver must wait for 16.0µs before sending another data to any analog output port. This function should be called before writing any data to the output port. While the DA value is sending, the returned value is “1”, otherwise the returned value is “0”.
5.9 _6308_DI @ Description This function is used to read data from the digital input ports. There are 4 digital input channels on the PCI-6308. The retrieved value is stored in DIData.
5.10 _6308_DO @ Description This function is used to write data to the digital output ports. There are 4 digital output channels on the PCI-6308, i.e. the output value ranges from 0 to 15.
5.11 _6308_I2V_Control @ Description This function is used to set the PCI-6308As’ voltage-to-current mode control. There are three range modes for the PCI-6308A. Please refer to section 3.3 for details of the voltage to current conversion.
