1.4 Software Supporting

The ACL-8111 is programmed using simple 8-bit I/O port commands. Users
can use high level language, such as BASIC, C, or PASCAL, or low- level
language, such as assembly to program the board. For the programming
under Windows or LabView, please contact your dealer to purchase ACLS­DLL2 or ACLD-LVIEW.

1.4.1 ACLS-DLL2

For easily program the board under Windows environment, we also provide

ACLS-DLL2

DLL2, you can use compilers such as VB, VC/C++, or Delphi. ACLS-DLL2 is
included in ADLINK CD. It need license.

1.4.2 ACLS-LVIEW

For easily link the ACL-8111 with LabView of National Instrument, the ACLS­LVIEW includes the Vis of the ACL-8111 under for Windows 3.1/95/98 and
NT. ACLS-LVIEW is included in ADLINK CD. It need license.

Installation

This chapter describes how to install the ACL-8111. The following list shows
the installation procedures:

1. Unpacking and check what you have.

2. Check the PCB and the location of jumper and switch.

3. Setup the jumpers according to the system and applications setting.

4. Installation the external termination boards.

5. Wiring with signals according to the connector pin assignments.

8 • Installation

2.1 Unpacking

The ACL-8111 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 anti­static 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, extract the system module and place it
only on a grounded anti-static surface component side up.

Again inspect the module for damage. Press down on all the socketed IC's to
make sure that they are properly seated. Do this only with the module place
on a firm flat surface.

Note:

DO NOT APPLY POWER TO THE CARD IF IT HAS BEEN

DAMAGED.

You are now ready to install your ACL-8111.

2.2 What You Have

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

• ACL-8111 multi-function data acquisition card

• ADLINK Software CD

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.

2.3 PCB Layout

In ACL-8111, there are three connectors (CN1~CN3), one switch (SW1), one
jumper (JP1) and 5 variable resistors (VR1~VR5). Please refer Figure 2.3 to
identify the location these components.

The card's jumpers and switches are preset at the factory. Please setup the
switch and jumper according to the system setting and the application
requirements.

A jumper is closed (sometimes referred to as "shorted") with the plastic cap
inserted over two pins of the jumper. A jumper is open with the plastic cap
inserted over one or no pin(s) of the jumper.

2.4 Base Address Setting

A

The ACL-8111 requires 16 consecutive address locations in I/O address
space. The base address of the ACL-8111 is restricted by the following
conditions.

1.

The base address must be within the range Hex 200 to Hex 3FF.

2.

The base address should not conflict with any PC reserved I/O address.
See Appendix A.

3.

The base address must not conflict with any add-on card on your own
PC. Please check your PC before installing the ACL-8111.

The ACL-8111's base address is selected by a 6 position DIP switch
SW1.The default setting of base address is set to be HEX 220. All possible
base address combinations are listed as Table 2.2. You may modify the
base address if the address HEX 220 has been occupied by another add-on
card.

How to Define a Base Address for the ACL-8111?

The DIP1 to DIP6 in the switch SW1are one to one corresponding
to the PC bus address line A9 to A4. A0, A1, A2, and A3 are
always 0. If you want to change the base address, you can only
change the values of A9 to A4 (shadow area of below table). The
following table is an example, which shows you how to define the
base address as

2.5 D/A Reference Voltage Setting

The analog output range of ACL-8111 depends on the reference voltage,
which is selected by JP1. There are two range of reference voltages can be
assigned as either -5V or -10V, that will generate output range 0V ~ +5V or
0V ~ +10V, respectively.

The setting of D/A reference voltage is specified as following:

When you select -10V for the D/A reference voltage, you should be very
careful the analog output. Because the -10 V voltage source is supplied from
your PC system, and it may be up to 11.5V only. Therefore, it will cause you
analog output is less than +10V.
