Introduction
The 6208 series products are multi-channel analog output cards. They
include the following three products:
•cPCI/PCI-6208V: 8-CH voltage output card for cPCI/PCI interface
•cPCI/PCI-6208A: 8-CH voltage and current output card for
cPCI/PCI interface
•PCI-6216V: 16-CH voltage output card for PCI interface
cPCI/PCI-6208V:
cPCI/PCI-6208V is a high-density analog output card with 8 identical
voltage output channels. Each channel is equipped with B.B.PCM56U
which 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.
PCI-6216V:
cPCI/PCI-6216V is a high-density analog voltage output card, it is a
combination of cPCI/PCI-6208 with EXP-8V daughter board. The EXP-
8V is an extended board which includes extra 8 voltage output
channels.
cPCI/PCI-6208A:
cPCI/PCI-6208A is a high-density current source output card, it is a
combination of cPCI/PCI-6208V with EXP-8A daughter board. The EXP-
8A includes 8 precision voltage-to-current converters which convert
voltage outputs from cPCI/PCI-6028V to current source outputs.

Installation
This chapter describes how to install the 6208 series card. Please follow
the following steps to complete the installation.
2.1 What You Have
In addition to this User's Manual, the package includes the following
items:
l6208 Series Card
lManual & Software Utility CD
If any of these items is missing or damaged, contact the dealer whom
you purchased the product from. Save the shipping materials and carton
in case you want to ship or store the product in the future.
2.2 Unpacking
Your 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.

6•• Installation
After opening the card module carton, exact the system module and
place it only on a grounded anti-static surface component side up.
Note : DO NOT APPLY POWER TO THE CARD IF IT HAS BEEN
DAMAGED.
You are now ready to install your 6208 series card.
2.3 Device Installation for Windows 95/98
While you first plug 6208 series card and enter Windows 95/98, the
system will detect this device automatically. Please follow the steps to
install the device.
1. Click the Next button in the Update Device Driver Wizard window,
Win95 will start to search floppy drive A for the 6208 series driver
information, After fail to find the information in drive A, it will
display the message “Windows was unable to locate a driver for
this device.”
2. Insert ADLink’s All-in-one CD-ROM drive.
3. Click the “Other Location…” button in the Update Device Driver
Wizard Window, then the Select Other Location windows will
appear.
4. Click Browse button to invoke the Browser for Folder window, then
select the location
X:\Win95Inf\6208 (Xindicates the CD-ROM drive).

10 •• Installation
2.6 Install 6208 Series Card to cPCI/PCI Connector
Note that the PC power should be ‘OFF’before installing, and be careful
to install the cards properly and tighten the screw. Improper installation
of the cPCI/PCI cards may damage the cards.
2.6.1 Hardware configuration
Memory usage (I/O port locations) of the cPCI/PCI card is assigned by
system BIOS. The address assignment is done on a board-by-board
basis for all cPCI/PCI cards in the system.
2.5.2 PCI slot selection
Your computer probably have both PCI and ISA slots. Do not force the
PCI card into a PC/AT slot. PCI slots are shorter than ISA or EISA slots
and are usually white or ivory.
2.5.3 Installation Procedures
1. Turn off your computer.
2. Turn off all accessories (printer, modem, monitor, etc.) connected to
computer.
3. Remove the cover from your computer.
4. Select a 32-bit cPCI/PCI expansion slot.
5. Before handling the 6208 series card, discharge any static buildup
on your body by touching the metal case of the computer. Hold the
edge and do not touch the components.
6. Position the board into the cPCI/PCI slot you selected.
7. Secure the card in place at the rear panel of the system unit by
using screw removed from the slot.
2.5.4 Running the 6208UTIL.EXE
A testing program is included in this utility, you can check if your 6208
series card can work properly. Refer Chapter 6 for further detailed
information.

Registers Format
In this chapter, the register format of the analog output channel and
digital I/O ports are introduced. Before programming or applying the
6208 series cards to your applications, please go through this chapter to
understand the features of the functions.
The 6208 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 6208 registers.
The PCR, which 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 LCR is specified by the PCI bus controller PLX-9050, which is
provided by PLX technology Inc. (www.plxtech.com) . It is not necessary
for users to understand the details of the LCR if you use the software
library. The base address of the LCR is assigned by the PCI PnP BIOS.
The assigned address is located at offset 14h of PCR.

12 •• Register format
3.1 Analog Output Registers
There are 8 and 16 voltage output channels for cPCI/PCI-6208V and
PCI-6216V respectively. For cPCI/PCI-6208A, there are 8 voltage and
current out-put channels, the voltage output controls the current source.
The programming method of all the analog output channels are
identical. For the three analog output cPCI/PCI cards, the programming
are compatible.
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 cPCI/PCI-6208A is
described in Section 3.3.
