Programming the DIO-16.LPCIe
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 DIO-16.LPCIe. 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.
Register Layout
Reference the following sections for more information about the meaning and use of the registers available.
Address Mode Mode D7 D6 D5 D4 D3 D2 D1 D0
Base+0 Input Port A RD PAD7 PAD6 PAD5 PAD4 PAD3 PAD2 PAD1 PAD0
Base+2 Output Port C RD/WR PCD7 PCD6 PCD5 PCD4 PCD3 PCD2 PCD1 PCD0
Reading the Inputs
The inputs are active Low. If no voltage is applied across one of the differential inputs, it returns a one on
that bit. If an AC or DC voltage is applied, it returns a zero on that bit.
Reading the Outputs
The relay ports return the ones complement of the value that is currently being used to drive the relays.
When using the API the actual value is returned not the complement of the value.

Writing the Outputs
The output ports are the only ports that can be written. The relays on a standard DIO-16.LPCIe are normally
open. To close a relay a one must be written to the appropriate bit.
Interrupts
Interrupts are not currently supported; however they may be added. Contact Sealevel with your
requirements.
Input Ports
Port A is an 8 bit input port 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 is also isolated with respect to the host PC
ground. This means that signals such as low-level AC line 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 applied voltage is high enough to cause the LED in the opto-isolator
to turn-on, the output of the opto-isolator goes low (0 volts) and the signal 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 1500 ohms (factory default). The opto-isolator
requires approximately 2 mA to turn on. The maximum input current is 20 mA.
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.

The above diagram is representative of how dry contact inputs (or current / voltage sources) can be
monitored by the optically isolated inputs. When switch 1 above is closed, it will allow current to flow from
the power source, into pin 3 of the DB-44, through the optocoupler, out pin 41, and back to the power source.
If the current flow is between 2 and 20 mA, this input will be read as logic “0”. All the input associated with
all open switches will be read as logic “1”.
In the diagram above, pins 36-38, and 40-44 are joined, providing a common return path for the
optocouplers. In this case, the interconnections are being made on the connector itself. In the DB-37
diagram below the return path is supplied external to the connector. Also for electrical isolation, each input
/ output pair can be powered from an individual power source with no common present.

Output Ports (Reed Relay)
Reed relays provide very high quality, long life, low current, dry contact switch closures. Reed relays are not
suited for high current applications, and can be destroyed by inductive load switching, where a spark occurs
across the contacts internally. The relays are normally open, and close when energized.
