Functional Description
The ETH-IDIO-16 Series (4, 8 and 16 channels) is an ideal solution for adding portable, easy-to-install,
isolated input and solid state output digital I/O capabilities to any Ethernet network. It is excellent for
controlling external relays, driving indicator lights, fuel pumps, high voltage control and more. Typical
industries are Automotive, Industrial, and Factory and Home automation.
This unit features 16 high-side MOSFET switch outputs and 16 optically isolated digital inputs. The isolated,
non-polarized inputs may be driven by either DC sources of 3-31 V (or higher by special order) or AC
sources at frequencies of 40 Hz to 10KHZ. Optically isolating the digital inputs from each other, and from the
computer and network, assures smooth, error-free data transmission in noisy, real-world environments.
The input channels are accessed via a 34-pin IDC type vertical header. The fully protected isolated outputs
are de-energized at power-up to prevent an unintended control output signal. Data to the solid state outputs
are latched and are available via a 50-pin IDC type vertical header. To simplify field wiring connections, the
ETH-IDIO-16 family includes an internal, removable termination board (ETH-STB-84), that mounts directly to
the headers.

The ETH-IDIO-16 is designed to be used in rugged industrial environments but is small enough to fit nicely
onto any desk or testing station. Its board is PC/104 sized (3.550 by 3.775 inches) and ships inside a steel
powder-coated enclosure with an anti-skid bottom.
The ETH-IDIO-16 has a DC Jack and screw terminals to connect the required external power. This power
can be provided by our PWR-ACDC-5V, your +5Vdc regulated power supply, or by ordering the –WI option
where you provide 7 VDC - 30 VDC.
OEM ETH/104 Form Factor
The OEM (board only) version is perfect for a variety of embedded applications. What makes the OEM option unique
is that its PCB size and mounting holes match the PC/104 form factor (without the bus connections). The board can
be added to any PC/104 type stack by connecting it to an available 10/100 base T port typically available on
embedded CPU form factors such as EPIC, and PC/104. It can also be installed using standoffs inside other
enclosures or systems.

Chapter 2: Installation
Software Installation
The software provided with this board is must be downloaded from the product page at
https://accesio.com/files/packages/ETH-IDIO-16 Install.exe then installed onto your system.
Hardware Installation
The board can be installed on any Ethernet network or even just connected directly to a NIC in your PC.
Installing the Ethernet module is as simple as connecting power, then the Ethernet cable itself. If you’re not
using an external supply with a DC jack, to connect power to the pair of screw terminals provided you’ll need to
open the enclosure by removing four screws and lifting off the lid. Insert your wires into the terminals
observing proper polarity and tighten the screw terminals. You may want to leave the lid off to start making I/O
field wiring connections on the removable spring cage terminal board. Turn the power on. You'll know it worked
if you see the link/activity light on the Ethernet connector housing light/blink. If you do not see activity, check
the other end of the Ethernet cable to ensure it is plugged into your LAN switch/router/gateway/hub/ or directly
into your PC.
This Ethernet module ships preconfigured at a factory-default MAC and IP Address and networking
configuration (listed in Chapter 4: Addressing). The Settings program allows you to change the module's
networking configuration to match your LAN requirements. However, in order to use the Settings program you
will need a Windows computer connected to the same subnet as the Ethernet module. (You can modify a
Windows PC's networking configuration temporarily if needed, contact an IT support staffer if you need
assistance with this.) In other operating systems please refer to the ETH API Doc (.html) for the low-level
command packet format for the “ChMC” command.
Any networking configuration changes made via the Settings program will be entered into the onboard non-
volatile memory and used at each power-on or reset in the future, as well as taking immediate effect.
If necessary you can reset the module to the factory default networking configuration by briefly shorting the
OPT1 jumper position while power is applied. (You may need to open the device' enclosure to reach the OPT1
jumper).

Option Selections
Refer to the settings program installed with the software package. Also, refer to the Block Diagram and the
Option Selection Map when reading this section of the manual.
Figure 3-1: ETH-IIRO-16 Option Selection Map
Ethernet Connector
The Ethernet Connector is an industry standard RJ45 10/100 Base T type with integrated transmit / receive
LEDs.
Input Filters
Filter jumpers are installed in the shipping configuration, which eliminates response to transient noise or spikes
on the inputs. For faster response to changing inputs, remove the filter jumpers for the affected channels.
LED The LED on the front of the board is used to indicate power when on steady, and activity / communication on
the Ethernet lines when flickering.

Manual ETH-IDIO-16 B1

DC Power Jack
The DC jack has a 2.00mm post and is designed to be used with the optional accessory AC/DC regulated 5V
external power supply.
When the –WI factory option is installed, the 7-30VDC external power may be connected to this jack.
DC Power Screw Terminals
If a more secure retention method of providing the unit with power is desired, use these clearly marked screw
terminals to connect regulated 5VDC.
When the –WI factory option is installed, the 7-30VDC external power may be connected to these screw
terminals.
Wide Input External Power Option (-WI)
This factory option allows the device to be powered from an external source of 7VDC to 30VDC. This external
power can be connected either via the DC Power Jack, or at the pair of screw terminals next to the DC jack.
The silk screen on the board labels these terminals as +5VDC and GND. Connect the + lead of your external
7 to 30VDC supply to the +5VDC terminal.
50 and 34 Pin Box Headers
These headers have standard 0.100" spacing between pins and are keyed to prevent improper connections. It
can be used with standard IDC type ribbon cables, or the included spring cage accessory board.

Chapter 4: Ethernet Address Information
Use the provided AIOETHW.dll driver to access the Ethernet board.
All units are shipped from the factory with an identical default MAC address: 00 08 DC 11 99 77. If you are
using more than one device in the same ethernet environment you will need to change the MAC.
The unit is shipped from the factory with a default static IP address: 192.168.1.174
Most customers will wish to change this IP address and related network configuration. Our Settings... program
can assist with this process in Windows. Refer to the ETH API Doc for details on the packet-level commands to
configure the device in other operating systems.
For your information, the device listens on port 51936 for normal operation, and listens on 51937 for upgrading
onboard firmware should it become necessary. Under very rare circumstances you may need to modify your
network settings to allow access to these ports.
The firmware supports at most six simultaneous connections during normal operation.

Manual ETH-IDIO-16 B1

Chapter 5: Programming
TCP/IP
This model family is TCP/IP. The source for our Windows DLL is installed with the samples, into the
.\Win32\Driver.SRC\AIOETHW\DLL\ directory. The intent is for any language and operating system able to
send TCP/IP packets to be able to utilize the unit.
Client API
To install the client, simply copy AIOETHW.dll next to the program that will use it, or to the 32-bit system
directory.
The general sequence to use it is:
•AEW_Connect() to open a connection.
•AEW_DIO_Configure() to set the initial digital input vs output configuration, and disable the tristate.
•Repeated I/O calls, using AEW_DIO_WriteAll()/AEW_DIO_Write1(), AEW_DIO_ReadAll().
•AEW_Disconnect() to close the connection when done.
If the connection fails during operation, a new connection can be swapped in, like this:
•AEW_Disconnect() to close the old connection.
•AEW_Connect() to open a new connection.
•Resume with the I/O calls.
The following is a brief reference of common AIOETHW.dll functions.
AEW_Connect()
AEW_Connect() connects to the specified host device. It returns a client reference (like a handle) that
represents the connection, or zero on a failure.
AEW_Disconnect()
AEW_Disconnect() disconnects a client reference, closing the connection and cleaning up any memory used.
After being passed to AEW_Disconnect(), the client reference is invalid.
AEW_GetStatus()
AEW_GetStatus() reads the device's status block.
AEW_DIO_Configure()
AEW_DIO_Configure() sets the direction of the DIO bytes, writes to all of them, and then disables the tristate.
Writes to input bytes are ignored.
AEW_DIO_WriteAll()
AEW_DIO_WriteAll() writes to all the DIO.
AEW_DIO_ReadAll()
AEW_DIO_ReadAll() reads from all the DIO.
For a complete AIOETHW.dll API reference please refer to the HTML API reference installed in your
software directory.

Low Level Interface Information
The following information is provided for users who cannot or choose to not use AIOETHW.dll. This is
necessary in non-windows operating systems. For your reference consider reading the source code for
AIOETHW.dll provided with your software install. More information is available in the HTML API reference
installed in your software directory
