Hardware Installation
2.1 Installation
This chapter gives users a package item checklist, proper instructions about unpacking and step-by-step procedures for both driver and card installation.
2.2 Initial Inspection
We carefully inspected the PCL-734 both mechanically and electrically before shipment. It should be free of marks and in perfect order on receipt.
As you unpack the PCL-734, check it for signs of shipping damage (damaged box,
scratches, dents, etc.). If it is damaged or fails to meet specifications, notify our service department or your local sales representative immediately. Also, call the carrier
immediately and retain the shipping carton and packing material for inspection by the
carrier. We will then make arrangements to repair or replace the unit.
Discharge any static electricity on your body before you touch the board by touching
the back of the system unit (grounded metal).
Remove the PCL-734 card from its protective packaging by grasping the rear metal
panel. Handle the card only by its edges to avoid static electric discharge which could
damage its integrated circuits. Keep the antistatic package. Whenever you remove
the card from the PC, please store the card in this package for protection.
You should also avoid contact with materials that hold static electricity such as plastic, vinyl and styrofoam.

2.4 Base Address selection (SW1)
You control the PCL-734's operation by reading or writing data to the PC's I/O (input/
output) port addresses. The PCL-734 requires four consecutive address locations.
Switch SW1 sets the card's base (beginning) address. Valid base addresses range
from Hex 200 to Hex 3F0. Other devices in your system may, however, be using
some of these addresses.
We set the PCL-734 for a base address of Hex 300 at the factory. If you need to
adjust it to some other address range, set switch SW1 as shown in the following
table:

Turn the computer off. Turn the power off to any peripheral devices such as
printers and monitors.
Disconnect the power cord and any other cables from the back of the computer.
Remove the system unit cover (refer to your user's guide chassis user's guide if
necessary).
Locate the expansion slots at the rear of the unit and choose any unused slot.
Remove the screw that secures the expansion slot cover to the system unit.
Save the screw to secure the interface card retaining bracket.
Carefully grasp the upper edge of the PCL-734 card. Align the hole in the retaining bracket with the hole on top of the expansion slot and align the gold striped
edge connector with the expansion slot socket. Press the board firmly into the
socket.
Secure the PCL-734 using the screw you removed in step 5.
Attach any accessories (i.e. a DB-37 cable, etc.) to the PCL-734.
Replace the system unit cover. Connect the cables you removed in step 2. Turn
the computer power on.

Signal Connections
3.1 Overview
Maintaining signal connections is one of the most important factors in ensuring that
your application system is sending and receiving data correctly. A good signal connection can avoid unnecessary and costly damage to your PC and other hardware
devices. This chapter provides useful information about how to connect input and
output signals to the PCL-734 via the I/O connector.
3.2 Connector Pin Assignments
The PCL-734 has a DB-37 connector accessible from the card bracket.
See the figure on page 9 for the location of each connector.
Pin assignments for each connector appear in the following sections.

Signal Connections
Each of isolated digital output channels come equipped with a MOSFET. Every eight
output channels share common emitters and integral suppression diodes for inductive loads. activated by connecting PCOM to VDD. (Channels 0~7 use PCOM1.
Channels 8~15 use PCOM2. Channels 16~23 use PCOM3. Channels 24~31 use
PCOM4.)
If the external voltage (5 to 40V) is connected to each isolated output channel (IDO)
and its isolated digital output turns on (max. of 200 mA per channel), the card's current will sink from the external voltage. The current through each E.GND should not
exceed 50 mA.
If the current for all channels combined exceed 150 mA, return the current to the
external voltage through CN2. The following figure shows how to connect an external
output load to the card's isolated outputs.

A.1 Register Format
Programming the PCL-734 is extremely simple. Each output channel corresponds to
a bit in the card's registers. To turn on an output channel you write a ‘‘1” to the corresponding bit.
The card requires four I/O register addresses. The address of each register is specified as an offset from the card's base address. For example, BASE+0 is the card's
base address and BASE+2 is the base address + two bytes. If the card's base
address is 300h, the register's address is 302h. See Chapter 2 for information on setting the card's base address.
