Installation

This chapter describes how to install the ACL-8216. At first, the contents in
the package and unpacking information that you should care about are
described. The jumpers and switches setting for the ACL-8216's base
address, analog input channel configuration, interrupt IRQ level, voltage
source, etc. are also specified.

2.1 What You Have

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

• ACL-8216 Enhanced Multi-function Data Acquisition Card

• ADLINK 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.

6 • Installation

2.2 Unpacking

Your ACL-8216 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-8216.

2.4 Jumper and DIP Switch Description

A (

)

You can change the ACL-8216's channels and the base address by setting
jumpers and DIP switches on the card. The card's jumpers and switches are
preset at the factory. You can change the jumper settings for your own
applications.

A jumper switch 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.

2.5 Base Address Setting

The ACL-8216 requires 16 consecutive address locations in the I/O address
space. The base address of the ACL-8216 is restricted by the following
conditions.

1.

The base address must be within the range Hex 000 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-8216.

The ACL-8216's base address of registers is selected by an 6 positions DIP

SW1

switch
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 add­on card.

. The default setting of base address is set to be HEX 220. All

A9 is always set as “1”.

How to define the base address for the ACL-8216 ?

The DIP1 to DIP6 in the switch SW1 are one to one
corresponding to the PC bus address line A8 to A4. A0~A3 are
always 0, and A9 is always 1. If you want to change the base
address, you can only change the values of A8 to A4 (the shadow
area of below table). The following table is an example, which
shows you how to define the base address as Hex 220

2.6 Analog Input Channel Configuration

The ACL-8216 offer 16 single-ended or 8 differential analog input channels.
The jumper JP3 controls the analog input channel configuration. The settings

2.7 DMA Channel Setting

The A/D data transfer of ACL-8216 is designed with DMA transfer capability.
The setting of DMA channel 1 or channel 3 is controlled by the jumpers JP8
and JP7. The possible settings are shown below.

Note: On floppy disk only machine, we suggest you to set DMA level 3. If

you have hard disk equipped computer, level 1 is preferable.

2.8 Internal/External Trigger Setting

The A/D conversion trigger source of ACL-8216 comes from internal or
external. The internal or external trigger source is setting by JP4, as shown
on Figure 2.5. Note that there are two internal on-board trigger sources, one
is the software trigger and the other is the programmable pacer trigger, which
is controlled by the mode control register(see section 4.5).

2.9 Clock Source Setting

The 8254 programmable interval timer is used in the ACL-8216. It provides 3
independent channels of 16-bit programmable down counters. The input of
counter 2 is connected to a precision 2MHz oscillator for internal pacer. The
input of counter 1 is cascaded from the output of counter 2. The channel 0 is
free for user's applications. There are two selections for the clock source of
channel 0: the internal 2MHz clock or the external clock signal from
connector CN3 pin 37. The setting of clock is shown as Figure 2.6.

2.10 IRQ Level Setting

The ACL-8216 can connect to any one of the interrupt lines of the PC I/O
channel. The interrupt line is selected by the jumper JP7. If you wish to use
the interrupt capability of ACL-8216, you must select an interrupt level and
place the jumper in the appropriate position to enable the particular interrupt
line.

The default interrupt level is IRQ15, which is selected by placing the jumper
on the pins in row number 15. Figure 2.7 shows the default interrupt jumper
setting IRQ15. You only remove the jumper from IRQ15 to other new pins, if
you want to change to another IRQ level.

Note

: Be aware that there is no other add-on card shares the same

interrupt level at the same system.

The D/A converter's reference voltage source can be internal or external
generated. The external reference voltage comes from connector CN3 pin
31(ExtRef1) and pin12(ExtRef2), see section 3.1. The reference source of
D/A channel 1 and channel 2 are selected by JP2, respectively. Their
possible settings are shown as below:
