The CVT-422-3 is an industrial grade (wide temperature range with surge & static protection) optically isolated bi-directional RS-232 to RS-422 converter, which can be used to convert any standard RS-232C port into a four-wire full-duplex RS-422 port and vice versa. This product features opto-isolation circuitry, which effectively protect your RS-232 devices from ground loops, transient surges and spikes. The unit is powered from the RS-232 data line; it also supports data direction auto-turnaround. Therefore, no external power or flow control is required.

120 Ohm End-of-Line Terminator (Built-in)

Self-explanatory, the 120 Ohm end-of-line terminator is to be connected at the end of the RS485/RS422 transmission line. This is important for building a reliable RS485/RS422 system, not only because of impedance matching, but also for the reduction of signal reflections and noise problems.



Note: The 120 Ohm end-of-line terminator adds heavy DC loading to a system and, therefore, it should be connected only when the RS485/RS422's distance is over 660ft (200m).
