This chapter describes how to install the PCI-6208. At first, the contents in the package and unpacking information that you should be careful are described.

In addition to this User's Manual, the package includes the following items:

If any of these items is missing or damaged, contact the dealer from whom you purchased the product. Save the shipping materials and carton in case you want to ship or store the product in the future.

Your PCI-6208 series card contains sensitive electronic components that can be easily damaged by static electricity.

The card should be done 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 damage. Shipping and handling may cause damage to your module. Be sure there are no shipping and handing damages on the module before processing.

After opening the card module carton, exact the system module and place it only on a grounded anti-static surface component side up.

You are now ready to install your PCI-6208 series card.

The pin assignment of PCI-6208/6208A/6216 are shown in Figure 2.2

The analog output pin names are specified as Vn or An, where

for PCI-6216V, n=0~15

The digital input and output pin names are specified as DIn and DOn respectively, where n=0~3.

After setting the jumpers according to users applications, you can install PCI-6208 on the PCI bus in your computer. Note that the PC power should be ‘ OFF’ before installing. Please be careful to install the cards properly and tied the screw. Improper installation of the PCI cards may damage the card.

PCI-6208 is equipped with plug and play components, the card thus can request an interrupt via a system call. The system BIOS responds with an interrupt assignment based on the PCI-6208‘ s configuration registers and known system parameters( which are set by system BIOS). The interrupt assignment is a function of the system, the system BIOS, the installed driver and the installed PCI boards.

Memory usage (I/O port locations) of the PCI-6208 is also assigned by system BIOS. The address assignment is done on a board-by-board basis for all PCI-6208s in the system.

Your computer will probably have both PCI and ISA slots. Do not force the PCI-6208 into a PC/AT slot.

Caution !! Don‘ t put PCI-6208 card into ISA or EISA card.

A testing program is included in this utility, you can check if your PCI-6208 can work properly. Refer Chapter 5 for further detailed information.

In this chapter, the register format and the operation theorem of the analog output channel and digital I/O ports are introduced. Before programming or applying the PCI-6208 cards to your applications, please go through this chapter to understand the features of the functions.

There are 8 and 16 voltage output channels for PCI-6208 and PCI-6216 respectively. For PCI-6208A, there are 8 voltage and current channels, the voltage output controls the current source. The programming method of all the analog output channels are identical. For the three analog output PCI cards, the programming are compatible.

The DA converters used on the PCI-6208/16 are Burr-Brown PCM-56U. The DAC is 16 bit resolution with bi-polar output. The voltage output range is +/-10V. Therefore, the data register are all 16-bits value with sign. The digital value range from -32768 (0X8000) to +32767 (0x7FFF) is corresponding to -10 Volt to +10 Volt. Table 3.1 shows the relation between the digital value and the analog output voltage.

When the applications use smaller voltage range, the PCI-6208 can still be applied. For example, if the application voltage range is uni-polar 0~5V, the user just use digital value range of 0~16384 with 14 bit voltage resolution.

The following table shows the address of every analog output ports relative to the base address. Note that the base address is assigned by the PCI BIOS. The current output control of the PCI-6208A is described in Section 3.3.

The DAC is with series bus hence it take times to send digital value out. The data transfer time for every DA data write takes 2.2m s, therefore the software driver must wait for 2.2m s before send another 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 write any data to output port. This register is read only.

The current output is implemented by the precision voltage-to-current converter XTR110. The current output channel n (An) is control by the voltage of channel n (Vn). The block diagram of the current output channels is shown in Fig 3.1.

The PCI-6208A provides an on board +15V power supply. Each current output channel is a current source which is controlled by the voltage of the corresponding channel. For example, voltage output channel 3 control the current source channel 3.

The output current range is programmable. All the 8 current channels on PCI-6208A are controlled by one control register. The control voltage range is always uni-polar 0~10V. There are three kinds of output current range. Refer to the following table and Section 4.2.7 for programming the current range by _6208_12V_Control function.

D4~D7 is digital input signal from CN1.

D0~D3 is read back signal from digital output channel.

Before calibrating your PCI-6208/6216 card, you should prepare a 6 1/2 digital multimeter for measruing the voltage signals.

There are 8 and 16 voltage output channels on PCI-6208 and PCI-6216 respectively. For each channel, two VRs are used for adjustment the full range and offset of the output voltage. The follow table shows the assignment and function of the VRs.

Because there is internal reference voltate for every DA channels, the calibration for every channles are independent. In the following procedure, VRn-1 and VRn-2 is used to represent the full range and offset of the nth channels. The following is the calibration procedure of the DA output.

The current output calibration is used only on PCI-6208A. Because the current output channel n is controlled by the voltage of channle n, the VR n-1 and VR n-2 is also used for calibrating the n th current output channel.

This chapter describes the software library for operating the PCI-6208/6216/6208A cards. The software is in C language and can be used under DOS environment. Seven C-language functions are provided in this software library to support users to program their own applications. The function prototypes and some useful constants are defined in the “ PCI_6208.H“ .
