Operating System Installation (For Windows Users)

RS-422/RS-485 Four Wire Master/RS-485 Two Wire Auto Mode Installation

If your application is 4-wire Full Duplex RS-422 or 4-Wire RS-485 Master, where control of the transmitter is not required, or 2-wire RS-485 and you intend to use the Auto Mode to control the transmitter, simply connect the OMG-CONV-485- ISO to an existing RS-232 COM: port. This will utilize the Operating System Serial Driver to control the COM: port. You will want to install the diagnostic utility, WinSSD, to test and verify proper operation of the port.

Start by choosing Install Software at the beginning of the CD. Choose Asynchronous COM: Port Software, SeaCOM. Continue with the installation until the “Setup Type” dialog, as shown below, appears. Choose “WinSSD Utility” to install just the diagnostic tool. A Start Menu Program Group, “SeaCOM” will be created and WinSSD can be started from there.
