Introduction
The ACL-7225 -16-CH Relay Actuator and Isolated D/I card is a
compact size ISA Bus card for industrial applications.
This card provides 16 relay actuators and 16 opto-isolated digital input
channels. You can use 16 on-board relays to control power switches or
ON/OFF control devices. Each relay is matched with one red LED to
reflect its ON/OFF status.
The 16 opto-isolated D/I channels are used to collect digital input data.
It is very essential to use isolated input to prevent the ground loop
problems. Each input channel is jumper selectable to either AC or DC
input control voltage. The isolation voltage is guaranteed at 1,000V, so
that common-mode voltages and voltage spikes that often occurs in
industrial environments are safety isolated form the PC and the ACL-
7225.
The digital I/O is via two 37 pin D-type connectors that project through
the computer case at the rear of the board.

Installation
This chapter describes how to install the ACL-7225. The following
procedures show the installation procedures:
1. Check what you have
2. Check the PCB and check the location of jumper and switch
3. Setup the jumpers according to the operation theorem
4. Installation the DOS software library if necessary
2.1 What You Have
In addition to this User's Manual, the package includes the following
items:
lACL-7225 Relay Actuator & Isolated D/I Card
lTwo DB-37 male connectors assembly
l40-pin to DB-37 converter flat cable
lADLINK 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.

2.2 Unpacking
Your ACL-7225 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.
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-7225.

2.4 Jumper and DIP Switch Description
You can change the ACL-7225's input signals and base address by
setting jumpers and DIP switches on the card. The card's jumpers and
switches are preset at the factory. Under normal circumstances, you
should not need to change the jumper settings.
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-7225 occupies eight consecutive address locations in I/O
address space. Actually, only 4 consecutive address loactions are used.
The base address of the ACL-7225 is restricted by the following
conditions.
1. The base address must be within the range 200hex to 3FFhex.
2. The base address should not conflict with any PC reserved I/O
address. see Appendix A.
The ACL-7225's I/O port base address is selectable by an 6 position DIP
switch SW1 ( refer to Figure 2.1). The default base address is set as
Hex 300, which is shown as following figure 2.2. All the possible
combinations of SW1 switch configuration are listed in the table 2.1
below.

How to Define a Base Address for the ACL-7225 ?
The DIP1 to DIP7 in the switch SW1 are one to one corresponding to
the PC bus address line A3 to A8. A9 is always set as 1, and A0, A1 and
A2 are always 0. If you want to change the base address, you can only
change the values of A9 to A3 ( shadow area of below diagram).
Following is an example, which shows you how to define the base
address asHex 300.

2.4 Input Signal Type Selection
The ACL-7225's input signal can be selected either AC input or DC
input signal. There are 16 jumpers (JP1...JP8 and JP9...JP16)
associated with each digital input channel for configuring the channel as
AC or DC input. The digital input channels and their corresponding
jumpers is shown in the following Table 2.3.

2.3 Connector Pin Assignments
The ACL-7225 card comes equipped with two I/O connectors CON1 and
CON2. The CON1 is an on-board 40-pin connector, and CON2 is a 37
pin D-type connector accessible from the rear panel of the card, and .
The pin assignment of these connectors is described by Figure 2.4 and
Figure 2.5, respectively.
Legend :
1. DIAn-digital input A of channel n
2. DIBn-digital input B of channel n
3. NCn-normal close pin of relay n
4. NOn-normal open pin of relay n
5. COMn-common pin of relay n
6. GND -ground
7. NC -Not Connected
Note : Isolated Digital Input is polarity-free, so you can connect the
digital inputs signal on input A and input B points and do not care
the polarity.

A cable connector to convert the CON1 40-pin header to 37-pinmaleD-
type connector is enclosed with the ACL-7225. The mapping between
the 40-pin header and 37-pin D-type connector are shown on next page.
