AMC-MUX interface converter
Interface converter, converts the signals from the RS232
interface bidirectionally into the RS485 2/4 wire or RS422
standard.
Functions
The RS485/RS422 system is electrically isolated from the
RS232 system and the power supply. Converting to RS485
increases the cable length from 15 m (50 ft.) to 1200 m
(3900 ft.) and the connection options for AMC's from 1 to
8.
The AMC-MUX can be expanded so that it has up to eight
RS485 lines, each with 1200m (3900 ft). Each additional
line requires an extension module (AMC-MUX-EXT). Via the
plug connection the AMC-MUX supplies power and RS232
signals to the extension modules. The extension modules
can be placed to the right or left of the AMC-MUX.

Installation/Configuration Notes
The AMC-MUX can be used at different places in a system.
One option is to convert the COM port of a computer
(RS232) to RS485/RS422.
Another option is to convert RS485/RS422 to RS232 if the
end device has only one RS232 interface.
