Connect USB A/B Cable between the IA-2104-U 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 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-2104-U 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-2104-U relays by either any serial control software,
or by the IA-3000 Utility, provided in the IA-3000 CD.

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 inform us that we should refer to COM4, in this case,
in order to control the IA-2104-U while connected to this computer through its USB port.

Start the IA-3000 Utility by pressing ‘Start’ on the computer’s main screen, select ‘All Programs’, and finally ‘IA-3000’.
Select ‘COM4’ to fit into the right of the ‘Port’ label (in case that this is the COM shown on item
2 of ‘Locating the new COM port’, earlier at this page).
Select ‘19200’ to fit into the right of the ‘Baud’ label (in case that the IA-2104-U is at its default setting stage).
Press the ‘Search’ button and wait for the utility to list all chained items.
As soon as all items are listed, you may press the ‘Stop Search’ button,
or you can let the software finish its search by itself.
Select the desired device out of the items’ list that appears beneath the ‘Search’ button.
Once the device is selected, its form will be shown in the right hand of the screen.
Left clicking the buttons will activate or disactivate the appropriate relay.

The following table is a quick reference table for the IA-2104U , A host computer / PLC may control the
IA-2104 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 return character.
All commands must use UPPER CASE characters
