USB or RS-232 Controlled
Introduction
The IA-3178-U2i is a 32 Channels Industrial Relay Controller, with 32 Power Relays and an
Isolated, High Voltage Line Monitor, designed and produced by Intelligent-Appliance.
The relays are of SPDT kind with a Contact Rating of 10Amp @ 30VDC, and 10Amp @ 240VAC.
They can be operated in a normal random way, or they can be operated in pairs, to provide
some sort of double pole.
The IA-3178-U2i includes an Isolated USB port and two Watchdog circuits.
The USB port isolation task is avoiding Ground Loops and EMI/RFI Interference, while the
second Watchdog task is providing a user defined way of handling Host computer and
Communication failure.
The IA-3178-U2i is being widely supported by Microsoft Studio Class Library, by National-
Instruments Labview Drivers and by various open code software examples.
The IA-3178-U2i can be controlled by a USB port or by an RS-232 port, while it can be easily and
transparently chained, supporting several Intelligent-Appliance Series-3000 products by a single
COM port.

Software Installation
USB Port setup
Connect USB A/B Cable between the IA-3178-U2i to the host computer.
The computer informs on locating a new USB device, and asks for S/W drivers.
Kindly choose the USB-Drivers directory on the IA-3000 CD or from our website:
www.intelligent-appliance.com, and complete the task by pressing ‘Next’ and ‘Finish’ while
asked for.
Job done will be accomplished by a steady lilting of the USB led on the IA-3178-U2i unit, and by
a creation of new Serial COM that can be easily found on the Device Manager screen.
At this stage you can easily control the IA-3178-U2i I/O’s by either any serial control software,
or by the IA3000Util Utility, provided in the IA-3000 CD (see next page).
Locating the new COM port
Start the ‘Device Manager’ utility. (Usually by selecting ‘My Computer’, Right Clicking the mouse
button, choosing manage, Left Clicking and then double Left clicking on the Device Manager will
list hardware items).
Select the ‘+’ character to the left of the ‘Ports (COM&LPT)’, and you’ll get a line that will define
for example: ‘USB Serial Port (COM4)’.
This line informs us that we should refer to COM4, in this case, in order to control the IA-3178-
U2i while connected to this computer through its USB port.

IA-3000 Utility
Install the IA3000Util Utility in your computer by clicking on the ‘Setup' icon in the ‘IA-Utility’
directory, on the IA-3000 CD.
Or download it from our online Knowledge Base. (www.intelligent-appliance.com)
Handling IA-3000 Utility
1. Start the IA3000Util Utility by pressing ‘Start Manu’ on the computer’s main screen,
select ‘All Programs’, and finally ‘IA3000Util'.
2. Select the appropriate COM
3. Select ‘19200’ to fit into the right of the ‘Baud’ label (in case that the IA-3178-U2i is at
its default setting stage).
4. Press the ‘Search’ button and wait for the utility to list all chained items.
5. Select the desired device out of the Module list that appears above the ‘Search’ button.

Command Set
The following table is a quick reference table for the IA-3178-U2i , A host computer / PLC may
control the IA-3178-U2i by simply sending ASCII commands though a standard COM port. Each
command is structured from a delimiter character, modules address, command character, data
if any carriage returns character. All commands must use UPPER CASE characters.
