Port-powered Isolated RS-232 to RS-485 converter
Port-powered, opto-isolated RS-232 to RS-485 converter. DE-9 female connector on the RS-232 side, DE-9 male or screw terminals on the RS-485 side. Optical isolation protects devices from transient surges and ground loops.
The SW485WA is an industrial grade bidirectional, isolated port-powered RS-232 to RS-485 converter. It can convert any standard full duplex RS232C port to any two-wire balanced half duplex RS-485 port or four-wire balanced full duplex RS-422 port.
The unit is powered from the RS-232 data lines. It also supports data direction auto-turnaround so no external power or flow control is required.
The data direction auto-turnaround automatically enables the RS-485/RS-422 driver when data is present on the RS-232 side making the device plug-and-play, requiring no software drivers.
The SW485C has a DB9 female connector on the RS-232 side and either a DE-9 male connector or 3-way terminal block on the RS-485 side.
