The ATEN IC485SN Interface Converter is a 2-way converter for transparently converting RS-232 signals to and from RS-422/RS-485 signals in long-distance applications up to 4,000' (1,200m) and needs no external power supply.
The converter provides point to point/multidrop and simplex operations over distances of 4,000' (1,200m), thus permitting the creation of reliable long distance data communication systems using standard computer hardware.
Data transmission controlled by RTS signals
Point to point/multidrop and simplex/duplex operating modes
Four wire full duplex and two wire half duplex
Cable distance of up to 4,000' (1,200m)
External power not required; power supplied by the RS-232 interface
