Introduction
Overview
The OMG-USB-485-1equips the PC with 1 USB to RS-530/422/485
Asynchronous serial port providing a versatile interface for common RS-
530/422/485 needs. The advantage of this product over more traditional
approaches is that it doesn’t require opening the computer case, nor does it
require resources such as I/O ports or IRQ’s. It does require a system that
supports USB both in terms of hardware and operating system.

Windows has now located a driver and installed the software. After the driver
has been located click “Finish. You should see one more “New Hardware
Found”, indicating the actual port being created. If you view your systems
Device Manager at this point, you should have a new “COM” port in the
Port(COM & LPT) Device Class. It should look similar to the screen shot on the
following page.
Installation
OMG-USB-485-1Page 5
You can access your new COM: port by using the assigned COM: identifier
shown above. In this case, it is COM5: but this assignment will vary from system
to system. At this point, the hardware is recognized. To verify operation use the
supplied WinSSD diagnostic utility. WinSSD can be found in the Start,
Programs group.
