Introduction
Overview
The OMG-CONV-485-ISO is a single channel RS-232 to RS-422/485
asynchronous converter. It provides one field selectable RS-422/485 serial port
supporting asynchronous data rates up to 115.2K bps. The OMG-CONV-485-
ISO is self-powered allowing it to correctly drive multi-drop RS-485 networks.

Configure the port as RS-422 for long distance device connections up to 4000ft.
where noise immunity and high data integrity are essential. Select RS-485 and
capture data from multiple peripherals in an RS-485 multi-drop network. Up to 31
RS-485 devices can be connected to automate your data collection.

In RS-422 and RS-485 Auto modes, the card works seamlessly with the standard
operating system serial driver. Two additional methods are provided to control
the communication line in RS-485 mode. The “Data Enable” mode uses the
transmitted data to enable the transmitter and requires no software drivers. This
mode has limitations that will be discussed in more detail later. The “RTS Enable”
mode uses the UART modem control signal RTS to control the communication
line and requires the serial driver.
