No jumper settings necessary
High Performance:

Guaranteed to work over a data range of 300 to 115200 bps
Very fast data turnaround. For 8 bit no parity: 0.2ms at 9600bps
Communication distance of up to 1.2km (4000 feet)
Versatile:

Small size, lightweight unit
9 – 24 volt power supply
Works with any terminal software
Easy to Install:

DIN rail mounting with universal foot for symmetrical and asymmetrical rails
RS232 side takes standard DB9 connector
Screw terminal connector with strain relief for RS485
Separate transmit and receive lights show data flow
Safe:

Full optical isolation protects your computer from power spikes
Robust, sealed plastic unit
Microprocessor has watchdog protection, preventing the possibility of the module holding the line on failure
Warranty:

Three years
Why choose the Control-it Converter?

The RS232 serial interface protocol is the only connection standard adhered to by all computer manufacturers. However RS232 is only able to operate effectively where the computer and a single device connected to it are situated within a few metres of each other.

Where information needs to be transmitted between multiple devices at distances of up to 1.2 kilometers remote from the computer, the RS485 protocol is able to achieve this economically using a 2 wire ‘twisted pair’ circuit. The Control-it 5251 easily and economically provides the interface between your computer’s RS232 port and the RS485 circuit.

The RS485 communications protocol operates like a telephone party line. One device communicates at a time. The Control-it 5251 converter is designed to enhance your data throughput up to 80% over similar converters.
