1 Introduction

The PCI-6308 series of isolated analog output cards includes the
following three cards:

X PCI-6308V: Isolated 8-CH voltage output card

X PCI-6308A: Isolated 8-CH voltage and current output card

X PCI-6304V: Isolated 4-CH voltage output card

The PCI-6308V is a high-performance, 12-bit analog output board
with PCI interface that provides 8 identical voltage output chan­nels, with each channel capable of: (1) bipolar
puts; (2) unipolar 0 - +10V voltage output; and (3) unipolar 0 to
user defined voltage output.

The PCI-6308V adopts the AD7564BRSZ, a state-of-the-art and
fully monotonic digital to analog converter. The AD7564 is a cur­rent output DA converter which requires external reference volt­age provided by TI REF102. The REF102 is a precision 10V
voltage reference. The drift is laser-trimmed to 2.5ppm/°C max
over the industrial temperature range.

The PCI-6308A is the combination of the PCI-6308V and a 8-CH
current output daughter board EXP-8A. The EXP-8A daughter
board includes 8 precision voltage-to-current converters/transmit­ters, which convert voltage output of PCI-6308V to a current
source output. The EXP-8A is piggybacked onto the PCI-6308V.
Therefore, the PCI-6308A provides both voltage and current out­puts at the same time. That is, the change of current output has
the direct proportion comparing to the change of voltage output.

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. These system resource
assignments are done on a board-by-board basis. It is not sug­gested to assign the system resource by any other methods.

PCI slot selection

The PCI card can be inserted into any PCI slot without any config­uration of the system resources. The CompactPCI card can also
be inserted into any CompactPCI I/O slot.

3Registers

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 low­level 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. There are three types of registers: PCI Config­uration Registers (PCR), Local Configuration Registers (LCR) and
PCI-6308 registers.

The PCR, which is PCI-bus specifications compliant, is initialized
and controlled by the plug & play (PnP) PCI BIOS. Users may
obtain more information on the PCI BIOS specification to better
understand the operation of the PCR. Please contact PCISIG to
acquire the specifications of the PCI interface.

The PCI bus controller PCI-9052 is provided by PLX technology
Inc. (www.plxtech.com). For more information about the LCR,
please visit PLX technology’s web site to download relative infor­mation. It is not necessary for users to fully understand the details
of the LCR if the software library provided is used. The PCI PnP
BIOS assigns the base address of the LCR. The assigned address
is located at an offset of 14h from the PCR.

The PCI-6308 registers are discussed in the next section. The
base address, which is also assigned by the PCI PnP BIOS, is
located at an offset of 18h from the PCR. Therefore, users can
read the address 18h from the PCR to obtain its base address by
using the BIOS function call. Do not attempt to modify the base
address and interrupt that have been assigned by the PCI PnP
BIOS, it may cause resource conflicts with your system.

Registers 19

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.

user can set the voltage output polarity by JP1~JP8. Please refer
to section 2.7 for detail of the jumper settings. The selectable
range is +/-10V, 0~+10V and 0V ~ user defined voltage. User­defined voltage is inputted from the DB-37 connector at pin #6.

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. For example, if the application voltage range
is uni-polar between 0~5V, user need only set jumper to external
reference mode, and supply a 5V source to pin 6 of CN1.

The above 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 PCI­6308A is described in Section 4.3.

24 Operation Theory

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 13
13

µs before sending another set of data to any analog output port.

µs, therefore the software driver must wait for

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.

0x00 X Data_Send

4.3 Current Output and Range Control

A precision voltage-to-current converter XTR110 implements the
current output. The current output channel n (An) is control by the
voltage of channel n (Vn). A block diagram of the current output
channels is shown in the figure below:

Figure 4-1: Current Output Circuit

The PCI-6308A provides an on board +15V power supply. Each
current output channel is a current source, which is controlled by
the voltage of the corresponding voltage output channel. For

example, voltage output channel 3 control the current source of
channel 3.

The output current range is programmable. The current range
control register controls all 8 current channels on the PCI-6308A.
There are three kinds of output current ranges. Refer to the follow­ing table and Section 5.2.9 for programming the current range
using the _6308_I2V_Control function.

0 0~10V 0~20 mA

1 0~10V 5~25 mA

2-- --

3 0~10V 4~20 mA

4.4 Isolated Digital Output

The isolated digital output is an open collector transistor output.
The isolation voltage between the isolated output and the host
power signals is 2500 Vrms

Figure 4-2: Isolated Digital Output

Note: Because the isolation DO is using open collector form, user

must add a series resistor on each DO channel to make the
DO works correctly.

Note: The Vsource can accept voltages of up to 24V.

4.5 Isolated Digital Input

The isolated digital input circuits have the following characteristics.
The input is equipped with a current-limit resistor. The input volt­age can be up to 35V. The isolation voltage between the isolated
input and the host power signals is 2500 Vrms.

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 4.0 or above, Visual C/C++ 4.0 or above, Bor­land C++ 5.0 or above, Borland Delphi 2.x (32-bit) or above, or
any Windows programming language that allows calls to a DLL.
The directory provides C/C++, VB, and Delphi INCLUDE files.

5.1 Libraries Installation

Please refer to the “Software Installation Guide” for detail infor­mation about how to install the software libraries for DOS, Win­dows 95 DLL, or PCIS-DASK for Windows 98/NT/2000.

The device drivers and DLL functions for Windows 98/NT/2000
are included with the PCIS-DASK. Please refer to the PCIS­DASK user’s guide and function reference, which is included in the

5.2 Programming Guide

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:

X _{hardware_model}_{action_name}. e.g. _6308_Initial().

C/C++ Library 29

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.

In order to distinguish the difference between DOS library and
Windows 95 library, a capital "W" is place on the beginning of each
function name of the Windows 95 DLL driver. e.g.

W_6308_Initial().

Data Types

We have defined some data type in the Pci_6308.h (DOS) and
Acl_pci.h (Windows 95) header files. These data types are used
by the PCI-6308/6216 library and suggest you use these data
types in your application programs. The following table shows the
data type names and their range.
