Introduction

The PCI-6308 series products are isolated analog output cards. The
PCI-6308 series includes three cards:

 PCI-6308V: Isolated 8-CH voltage output card
 PCI-6308A: Isolated 8-CH voltage and current output card
 PCI-6304V: Isolated 4-CH voltage output card

The PCI-6308V is high-performance, 12-bit analog output boards with
PCI interface. The PCI-6308V provide 8-CH identical voltage output
channels, each of channel has: (1) bipolar 10V voltage outputs; (2)
unipolar 0~+10V voltage output; and (3) unipolar 0 to user defined
voltage output. The DA chip is the DAC-4814AP that is a state-of-the-

art, fully monotonic, digital to analog converter. This device employs
ultra-stable nichrome (NiCr) thin-film resistors to provide monotonicity,
low distortion, and low differential linearity error over long period of
time.

The PCI-6304V is for large quantity OEM only. It is fully compatible
with PCI-6308V, but with four voltage-output channels only. The

functionality, software interface and detail operation of PCI-6304V is
exactly the same as PCI-6308V. Therefore, there will have no more
description about PCI-6304V in this manual.

The PCI-6308A is the combination of PCI-6308V with an 8-CH current
output extended board called EXP-8A. The EXP-8A board includes 8

precision voltage-to-current converters/transmitters, which convert
voltage output of PCI-6308V to current source output. The EXP-8A is
piggy back on the PCI-6308V. Therefore, the PCI-6308A provides not
only voltage output but also current output. The total number of analog

output channel is still 8.

Registers Format

The detailed descriptions of the registers format are specified in this
chapter. This information is quite useful for the programmers who wish

to handle the card by low-level programming. However, we suggest
user have to understand more about the PCI interface then start any
low-level programming. In addition, the contents of this chapter can help
users understand how to use software driver to manipulate this card.

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 compliant to the PCI-bus specifications, is initialized
and controlled by the plug & play (PnP) PCI BIOS. User¡¥s can study the

PCI BIOS specification to understand the operation of the PCR. Please
contact with PCISIG to acquire the specifications of the PCI interface.

The PCI bus controller PCI-9050 is provided by PLX technology Inc.
(www.plxtech.com). For more detailed information of LCR, please visit

PLX technology¡¦s web site to download relative information. It is not
necessary for users to understand the details of the LCR if you use the
software library. The PCI PnP BIOS assigns the base address of the
LCR. The assigned address is located at offset 14h of PCR.

The PCI-6308 registers are shown in the next section. The base
address, which is also assigned by the PCI PnP BIOS, is located at

offset 18h of PCR. Therefore, users can read the 18h of PCR to know
the base address by using the BIOS function call.

Please do not try to modify the base address and interrupt which
assigned by the PCI PnP BIOS, it may cause resource confliction in

your system.

Registes Format  15

3.2 I/O Address Map

Most of the PCI-6308 registers are 16 bits. The users can access these
registers by 16 bits I/O instructions. The following table shows the

registers map, including descriptions and their offset addresses relative
to the base address.

Operation Theorem

In this chapter, the detail operation theorem of PCI-6308V and PCI­6308A is described. Before programming or applying the PCI-6308

cards to your applications, please go through this chapter to
understand the features of the functions.

4.1 Voltage Output

There are 8 voltage output channels for PCI-6308V and 6308A. For
voltage output operation, you have to understand:

1. How to set the voltage output range.

2. The DA data format.

4.1.1 Voltage Output Range Selection

The DA converters used on the PCI-6308 are Burr-Brown
DAC4814AP. This DAC is 12 bits resolution with bipolar or unipolar
output. The voltage output range is jumper selectable by JP1~JP8.
Please refer to section 2.7 for detail of the jumper setting. The
selectable range is +/-10V, 0~+10V and 0V ~ user defined voltage.

The user-defined voltage is input from the DB-37 connector¡¦s pin #6

4.1.2 DA data format

The DA data format is 12-bits unsigned value for all channels, that is,
the value is in binary format. The digital value range from 0(0X000) to
+4095(0xFFF) is corresponding to full span of the output range, which
is setting by jumper. Table 4.1 shows the relation between the digital
value and the analog output voltage.

18  Operation Theorem

When the applications use smaller voltage range, the PCI-6308 can
still be applied. For example, if the application voltage range is uni-

polar 0~5V, the user just need to set jumper to external reference
mode, supply 5V from CN1 connector.

For +/-10V mode:

Digital Value HEX value

Output Voltage

4095 0xFFF +9.99969V
2048 0x800 0.00000V

0 0x000 -10.00000V

For 0~+10V mode:

Digital Value HEX value

Output Voltage

4095 0xFFF +9.99969V
2048 0x800 5.00000V

0 0x000 0.00000V

For 0V ~ Vuser mode:

Digital Value HEX value

Output Voltage

4095 0xFFF +Vuser
2048 0x800 +Vuser/2

0 0x000 0.00000V

Table 4.1 DA Voltage Output Format

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-6308A is
described in Section 4.3.

4.2 Analog Output Status Register

The DAC is with series bus hence it takes times to send digital value
out. The data transfer time for every DA data write takes 16s,
therefore the software driver must wait for 16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.

4.3 Current Output and Range Control

The current output is implemented by a 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 4.1.

Range Control

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 channel 3.

The output current range is programmable. All the 8 current channels
on PCI-6308A are controlled by current range control register. There

are three kinds of output current range. Refer to the following table
and Section 5.2.9 for programming the current range by
_6308_I2V_Control function.

collector type. The isolation voltage between the isolated output and

the host power signals is 5000 Vrms.

4.5 Isolated Digital Input

The isolated digital input circuits are as following. The input is
equipped with current-limit resistor. The input voltage could up to 34V.

The isolation voltage between the isolated input and the host power
signals is 5000 Vrms.

Please refer to the PCIS-DASK function reference manual, which
included in ADLINK CD, for the descriptions of the Windows
98/NT/2000 DLL functions.

The function prototypes and some useful constants are defined in the
header files 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. It provides the

5.2 Programming Guide

5.2.1 Naming Convention

There are 7 function calls provided by the C Language Library. All the
functions of PCI-6308 are covered in this library. Its capabilities include
D/A conversion, Digital Input and Output, etc.

The functions of PCI-6308 software driver are using 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 PCI-6308 driver are with 6308 as {hardware_model}. But
they can be used by PCI-6308V, PCI-6308A.

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

W_6308_Initial()

.

5.2.2 Data Types

We defined some data type in Pci_6308.h (DOS) and Acl_pci.h
(Windows 95). These data types are used by PCI-6308/6216 library.

We suggest you to use these data types in your application programs.
