24 ADAM-4572 User's Manual
3kinds of serial interfaces can be connected to ADAM-4572. Every Mod-
bus device connected to any of the 3 serial buses must have a unique
Modbus ID, and can be accessed from host PC through ADAM-4572.
RS-422 - When configuring the ADAM-4572 serial port to RS-422, RS-
422 and RS-232 type of serial interfaces can be connected to ADAM-
4572. All devices connected to these 2 serial buses can be accessed from
host PC through ADAM-4572.
RS-232 - When configuring the ADAM-4572 serial port to RS-232, only
the RS-232 type of serial interface can be connected to ADAM-4572.
