with Driver Library [API-PAC(W32)]

Ver.1.00

This board is a PCI-compliant interface board for input/output of
digital signals.
The board can input the open/closed circuit states of switches and
can control relays.
< PIO-64/64L(PCI)H > can input and output up to 64 channels.
< PI-128L(PCI)H > can input up to 128 channels.
< PO-128L(PCI)H > can output up to 128 channels.
Using the bundled Driver Library [API-PAC(W32)], you can create
Windows application software for this board in your favorite
programming language supporting Win32 API functions, such as
Visual Basic or Visual C/C++.

Features

- Common power-supply configuration in 16 channel units, capable of supporting different external power supplies.

- Opto-coupler used to electrically isolated I/O signal interface from the PCI bus, offering good noise immunity.

- Capable of using up to 16 channels of input signals as interrupt inputs.
Also capable of selecting the input signal edge for generating interrupts

< PIO-64/64L(PCI)H >, < PI-128L(PCI)H >

- Digital filtering that prevents input signal noise and chattering.

< PIO-64/64L(PCI)H >, < PI-128L(PCI)H >

- Up to 35VDC, 100mA per signal, max. output.

< PIO-64/64L(PCI)H >, < PO-128L(PCI)H >

- Zener diode connected to output transistors for protection from surge voltage. Over-current protective device provided for every eight channels
of output transistors.

Support Software

You should use CONTEC support software according to your
purpose and development environment.

API-PAC(W32) is the library software that provides the commands
for CONTEC hardware products in the form of Windows standard
Win32 API functions (DLL). It makes it easy to create high-speed
application software taking advantage of the CONTEC hardware
using various programming languages that support Win32 API
functions, such as Visual Basic and Visual C/C++.
It can also be used by the installed diagnosis program to check
hardware operations.
CONTEC provides download services to supply the updated drivers
and differential files.
For details, read Help on the bundled CD-ROM or visit the
CONTEC's Web site.
< Operating environment >
OS Windows XP, 2000, NT, Me, 98, etc..
Adaptation language Visual C/C++, Visual Basic, Delphi, Builder,

etc..

This driver is used to control CONTEC digital I/O boards (cards)
from within Linux.
You can control CONTEC I/O boards easily using the shared library
used by gcc and Kylix, the device driver (module) for each kernel
version, and the board (card) configuration program (config).
CONTEC provides download (at http://www.contec.com/comm/)
services to supply the updated drivers and differential files.

Connecting Input Signals

Connect the input signals to a device which can be current-driven,
such as a switch or transistor output device.
The connection requires an external power supply to feed currents.
The board inputs the ON/OFF state of the current-driven device as a
digital value.

The input circuit of this board is illustrated in Figure 3.5. The on­board opto-couplers isolate internal input circuits from outside
devices. The input channels are to be connected with current sinking
output signals. Driving these opto-isolated circuits require an
additional power supply isolated from the PC system. When a
12VDC external power is used, each input channel will consume
about 2.6mA current; when a 24VDC external power supply is
selected, each input channel will consume about 5.1mA current.

The output circuit of this board is illustrated in Figure 3.7. The
signal output section is an opto- isolated, open-collector output
(current sink type). Driving the output section requires an external
power supply.
The rated output current per channel is 100 mA at maximum.
The output section can also be connected to a TTL level input as it
uses a low-saturated transistor for output. The residual voltage
(low-level voltage) between the collector and emitter with the output
on is 0.5 V or less at an output current within 50 mA or at most 1.0
V at an output current within 100 mA.
A zener diode is connected to the output transistor for protection
from surge voltages. A PolySwitch-based over-current protector is
provided for every eight output transistors. When the over-current
protector works, the output section of the board is temporarily
disabled. If this is the case, turn of the power to the PC and the
external power supply and wait for a few minutes, then turn them on
back.
