Chapter 1: Introduction
The PCI-16P16R 16-CH Relay Actuator and Isolated D/I card
is a compact-size and PCI-Bus digital I/O card for IBM
personal computer or compatibles in controlling and sensing
applications.
This card provides 16 relay actuators and 16 opto-isolated
digital inputs. You can use 16 on-board relays to control
power switches or ON/OFF control devices, and use 16 opto-
isolated D/I channels to collect digital inputs in any noisy
environments. It is very essential to use isolated input to
prevent the ground loop problems.
Each relay is matched with one red LED to reflect its ON/OFF
status. 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 from the PC and the PCI-16P16R.
The digital I/O is via one 37 pins D-type connector that project
through the computer case at the rear of the board.

Chapter 2: Installation
This chapter describes how to install the PCI-16P16R. At first,
the contents in the package and unpacking information that
you should be careful are described. The jumpers and
switches setting for the PCI-16P16R base address and digital
input configuration (AC signal or DC signal) are also
specified.
2.1 What You Have
In addition to this User’s Manual, the package includes the
following items:
lPCI-16P16R Relay Actuator & Isolated D/I Card
lTwo DB-37 male connectors
l40-pin to DB-37 converter flat cable
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 PCI-16P16R card contains sensitive electronic
components that can be easily damaged by static electricity.

-6-Installation
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.
Shippingand handling may cause damage to your module.
Be sure there are no shipping and handling 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 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 PCI-16P16R

2.4 Jumper and DIP Switch Description
You can change the PCI-16P16R’s input signals by setting
jumpers on the card. The card’s jumpers 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 Input Signal Selection
The PCI-16P16R’s input signal can be selected as either AC
input or DC input signal. There are 2 jumpers (J1 and J9)
associated with each digital input channel for configuring the
channel as AC or DC input. The digital input channels and
their corresponding jumpers are shown in the following
Table 2.3.

2.6 Connector Pin Assignments
The PCI-16P16R card comes equipped with two I/O
connectors CON1 and CON2. CON1 is a 37-pin D-type
connector accessible from the rear panel of the card and
CON2 is an on-board 40-pin connector. The pin assignment
of these connectors is described in Figure2.2 and Figure2.3
respectively.

the digital inputs signal on input A and input B points and
do not care the polarity.

A cable connector to convert the CON2 40-pin header to
37-pin male D-type connector is enclosed with the PCI-
16P16R. The mapping between the 40-pin header and 37-
pin D-type connector are shown below.

Chapter 3: Low-level Programming
A low-level programming interface of PCI-16P16R is
described in this chapter. If you wish to control the digital
input/output operations through the primitive I/O functions
(inportb and outportb), you have to be careful to understand
the meaning of the structure of the 8 registers. Here, you will
get all detailed information of the PCI-16P16R’s register
format and control procedures.
3.1 I/O Port Address Map
The PCI-16P16R requires 2 consecutive addresses in the PC
I/O address space. The following table (Table 3.1) shows the
location of each register and driver relative to the base
address and its description.

Base+00 Isolated inputs
(DI0~DI15) Relay outputs (R0~R15)
Base+02 Relay outputs Status (Read

3.2 Relay Output Register –Base+00
The PCI-16P16R provides 16 relay output channels. The
ON/OFF status of each relay is controlled by its
corresponding bit of register, i.e. the control bit is low (0)
status, it turns the relay OFF, and high status (1) will energize
the relay.
The readback capability is also supported in the PCI-16P16R,
i.e. you can read back each relay’s status through Base+02
register.
The relationshipsbetween the bitsof relay output register and
their corresponding relay are shown as below.

3.3 Isolated Input Registers.
There are 16 non-polarity isolated inputs provided in the PCI-
16P16R. The register is read-only, as it uses to get status
from input channels.

3.4 Relay Output
The PCI-16P16R contains two types of relay: Form C and
Form A. The relay R0~R4 and R8~R12 are form C relays,
and R5~R7 and R13~R15 are form A type. The differences
between these two types of relay are:
