Advantech warrants to you, the original purchaser, that each of its products will be
free from defects in materials and workmanship for two years from the date of purchase.
This warranty does not apply to any products which have been repaired or altered by
persons other than repair personnel authorized by Advantech, or which have been
subject to misuse, abuse, accident or improper installation. Advantech assumes no
liability under the terms of this warranty as a consequence of such events.
Because of Advantech’s high quality-control standards and rigorous testing, most of
our customers never need to use our repair service. If an Advantech product is defective, it will be repaired or replaced at no charge during the warranty period. For outof-warranty repairs, you will be billed according to the cost of replacement materials,

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-730 both mechanically and electrically before shipment. It should be free of marks and in perfect order on receipt.
As you unpack the PCL-730, 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-730 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-730's operation by reading or writing data to the PC's I/O (input/
output) port addresses. The PCL-730 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-730 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:

Disconnect the power cord and any other cables from the back of the computer.
Remove the system unit cover (see the user's guide for your chassis 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-730 card. Align the hole in the retaining bracket with the hole on top of the expansion slot and align the gold striped

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-730 via the I/O connector.
3.2 Connector Pin Assignments
The PCL-730 has four on-board 20-pin flat-cable connectors (insulation displacement, mass termination) and a DB-37 connector accessible from the card bracket.
See the figure on page 7 for the location of each connector.
Pin assignments for each connector appear in the following sections.
*NOTE: When JP4 is set to B1, Pin 19 on CN1 and Pin 10 on CN6 will both be
assigned PCOM1. When JP4 is set to A1, both pins will be assigned E.GND. For
JP5, Pin 17 & 19 and Pin 18 & 20 on CN2 will combine together (be the same GND)
when JP5 is set to A1. But Pin 17 & 19 and Pin 18 & 20 on CN2 will be different GND
(EI.GND1 and EI.GND2 separately) when JP5 is set to B1.

3.3 TTL-level I/O
The PCL-730 has 16 TTL-level digital inputs and 16 TTL-level digital outputs. The following figure shows connections to exchange digital signals with other TTL devices:
If you want to receive an OPEN/SHORT signal from a switch or relay, add a pull-up
resistor to ensure that the input is held at a high level when the contacts are open.
See the figure below:
3.3.1 Isolated Input
Each of the 16 isolated digital input channels accept voltages from 5 to 24V and have
a resistance of 3 kΩ. Every eight input channels share one external ground. (Channels 0~7 use EI.GND1. Channels 8~15 use EI.GND2.) The following figure shows
how to connect an external input source to the card's isolated inputs:
PCL-730 User Manual
14
Each of the 16 isolated digital output channels comes equipped with a MOSFET.
Every eight output channels share common emitters and integral suppression diodes
for inductive load, activated by connecting PCOM to VDD. (Channels 0~7 use
PCOM1. Channels 8~15 use PCOM2.)
If the external voltage (5~40V) is connected to each isolated output channel (IDO)
and its isolated digital output turns on (200mA per channel maximum), the card's current will sink from the external voltage.

A.1 Register Format
Programming the PCL-730 is extremely simple. Each I/O channel corresponds to a
bit in the card's registers. To turn on an output channel you write a ‘‘1” to the corresponding bit. To read an input port, you simply read from the register.
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.
