Protocol Converters



This RS232-RS485 Converter is externally powered, optically isolated, bi-directional unit. The unit works as 2 wire or 4 wire converter selecting through DIP switch. This can be used to convert any standard Rs-232 port into two wire half-duplex RS-485 port and vice versa. This product features opto-isolation circuitry, which effectively protects your Rs-232 devices from ground loops, transient surges, lightening and spikes; it also supports data direction and auto turn around and works up to 115200 bps. The unit does not require software drivers or flow control is necessary.
