ISO-16.PCI User Manual
Programming the ISO-16.PCI
Sealevel’s SeaI/O software is provided to assist in the development of reliable
applications for the Sealevel Systems family of digital I/O adapters. Included on the
SeaI/O CD are driver functions for use in accessing the I/O as well as helpful
samples and utilities.
Programming for Windows
The SeaI/O API (Application Programmer Interface) provides a variety of useful
high-level function calls implemented in a Windows dynamic link library (DLL).
The API is defined in the help file (Start/Programs/SeaIO/SeaIO Help) under
“Application Programmers Interface”. This help file also includes detailed
information dealing with installation / removal of the software and information
about latency, logic states, and device configuration.
For C language programmers we recommend using the API to access the ISO-
16.PCI. If you are programming in Visual Basic, using the ActiveX control
included with SeaI/O is advised.
Samples and Utilities
A variety of sample programs and utilities (both executable and source code) are
included with SeaI/O. Further documentation on these samples can be found by
selecting “Start/Programs/SeaIO/Sample Application Description”. Information
about where the files are physically stored on your disk is also included in this same
file.
Programming for Linux
SeaI/O for Linux consists of two major parts: a kernel module and a library. The
kernel module is a simple IO pass-through device, allowing the library to handle the
more sophisticated functions provided to SeaI/O users. It is provided in a ‘tarball’
format and can easily be compiled and included in the kernel build.
Digital I/O Interface
The ISO-16.PCI provides two parallel input ports. Port A and B are interfaced to
optically isolated inputs. Assuming an I/O address of 300 Hex the following table
shows the Port Addresses.
Base Address Hex Decimal Mode
Port A Address 300 768 Input Port
Port B Address 301 769 Input Port

ISO-16.PCI User Manual
Input Ports
Ports A and B are 8 bit input ports connected to optically isolated input sensors.
Each sensor can be used to interface a voltage input and then sense whether the
voltage is on or off. Each sensor is isolated with respect to a common ground from
every other sensor and also isolated with respect to the host PC ground. This means
that signals such as low-level AC voltage, motor servo voltage, and control relay
signals can be ‘sensed’, or read by the PC, without the risk of damage due to ground
loops or ground faults.
Each sensor input pair has a current limiting resistor that is used to limit the input
current to the opto-isolator. The opto-isolator has two ‘back-to-back’ diodes
internally. This allows AC or DC signals to be sensed regardless of polarity. When
the signal is high enough to cause the opto-isolator to turn-on, the output of the optoisolator goes low (0 volts) and the port bit is read as a low logic level (binary 0) by
the PC. When the input signal is too low to turn on the opto-isolator, the output goes
high and the port bit is read by the PC as a high logic level (binary 1).
The input impedance of each isolated input is approximately 560 ohms
(factory default). The opto-isolator requires approximately 3mA to turn on. The
maximum input current is 50mA. There are two things to consider when selecting
the input resistor. The first is turn on voltage for the circuit to sense, and second is
the maximum input voltage. Maximum input voltage must not provide too much
power to the input resistor, and must also not overdrive the opto-isolator input
current specification. The following formulas apply:
Turn on Voltage = diode drop + (turn on current) x (resistance)
[Ex: 1.1 + (.003) x R]
Input Current = ((input voltage)-1.1V) / (resistor value)
Maximum voltage = 1.1 + square root of (.25(resistor value))
The following table shows common input resistors and the ranges associated with
each.
Input Resistor Turn-On Input Range Max Input Max Current
220Ω
560Ω
1KΩ
2.2KΩ
3.3KΩ
4.7KΩ
1.8V 1.8 – 7.0V 8.5V 27mA
2.8V 2.8 – 10.6V 12.9V 20mA
4.1V 4.1 – 13.8V 16.9V 15mA
7.7V 7.7 – 20.0V 24.5V 10mA
10.0V 10.0 – 24.0V 30.0V 9mA
15.2V 15.2 – 28.0V 35.0V 7mA
Note: The turn-off voltage for all resistors is less than 1V.
Increasing the input resistor accordingly can increase the maximum input voltage.
Because socketed DIP resistors are utilized, they can easily be replaced with a
different value. Sealevel, if necessary can do this.
Important: The input circuits are not intended for monitoring 120-volt AC circuits.
In addition to being too high a voltage for the circuits, it is dangerous to have that
high a voltage on the card.

Note: For ease in wiring, the card’s DB37 connector can be interfaced directly to the
Sealevel terminal block kit, Item# KT-101. This kit includes a 6’ Male/Female cable
(Item# CA112) and terminal block with screw terminals (Item# TB02) which
provides a simple means to connect field wiring to Sealevel DB37 I/O cards. The
TB02 provides both male and female DB37 connectors, eliminating the need for
gender benders and other adapters while simplifying cable connections.
Direct Hardware Control
In systems where the users program has direct access to the hardware (DOS) the
table below gives the mapping and functions that the ISO-16.PCI provide. The
address of each eight-bit port is calculated as shown in the table on the following
page, the cards base address plus an offset.
