Introduction
Thank your for purchasing the Ether I/O 24 Module. We trust that programming and using the Ether I/O
24 will prove to be an ongoing positive experience for you.
Please take a moment to unpack and inspect your module to ensure it is undamaged and is complete with
the items listed in the contents section. As the module has several connectors that are critical to its correct
operation, please take a moment to familiarize yourself with the Module’s layout and connector locations.
Along with the module itself you will require the following items for its operation.
1.
A Power Supply 8 - 34V DC, Minimum 1.2Watts (0.1A@12V / 0.05A@24V)
2.
A PC equipped with an Ethernet Network Interface and Software to support the TCP/IP protocol
suite
3.
A Network cable for connection of the Module to your networks hub/switch or a crossover cable
for connection directly to the PC
4.
One or more 5V operable devices or switches and connecting cables for operation by, or
connection to the module. (A range of accessory devices are available from your ELEXOL
distributor.)
The module’s test and programming software is only operable on a PC with the Windows operating system.
Your own software can be written to operate and program the module from any platform that has an
Ethernet connection. Full details of the programming and operation of the module are contained in the
programming sections of this manual.
UDP/IP packets sent over the network from any device with appropriate software are able to operate the
Ether I/O 24. The module has DHCP support to allow it to automatically obtain its IP address from a
suitable server device. If a DHCP server is not available, the module may be configured by jumper link to
a fixed address to allow for initial programming operations. Once programmed, the device may have any
IP address the user assigns.
Three Ports labeled Port A, Port B and Port C are for connection of the module to external digital devices
operating at 5V levels. These ports are standard 10 way box headers with 0.1” pitch. Each of these ports
has 8 I/O signals and the +5V and Ground lines from the module. As these groups of 8 signals are treated
as a single byte for the efficient use of software resources, it is best to connect devices of the same type to
the same port. For Example, If you had LED illuminated switches then it would be recommended to
connect your switches to Port A and your LED’s to Port B, then to make the switches control the LED’s
you could simply read the value from Port A and write that value to Port B.
Non-volatile memory on the module can be programmed to allow the module to have a fixed, user
assigned, IP address, to each of the ports to power up in a user defined state and/or to allow the module to
automatically scan any of it’s input lines at a user defined rate, filter the signals digitally and transmit a
UDP/IP packet to report any valid input line changes to a user programmed destination address.
The Ether I/O 24 module has been designed and manufactured as a component of a larger system that may
consist of the module combined with, your own input and/or output devices, any of our accessory boards
connected to other components or modules, other 5V level operated modules and devices by direct
connection.
The Ether I/O and all of the accessory modules are built to a 72 mm standard width thereby allowing their
easy mounting to a DIN rail by means of commonly available DIN rail mounting hardware.
The Ether I/O and all of the accessory modules also have mounting holes to allow 3mm or 1/8” mounting
hardware to be used. Care should be taken so as not to damage the printed circuit boards when mounting
the modules.
