The CVT-422-1 is a compact, rugged, industrial-grade, port-powered, bi-directional RS232 to RS422 converter, which can be used to convert any standard full-duplex unbalanced RS-232C port into a four-wire full-duplex balanced RS422 port and vice versa.

This industrial-grade RS232 to RS422 adapter operates within a wide temperature range (-40F to 185F / -40C to 85C), features 600W surge protection and 15kV static protection, and comes with a built-in 120 Ohm terminator for system reliability and easy installation. The unit is powered from the RS232 data line, it requires no external power, software drivers or flow control, making the unit a rugged, highly reliable, and truly plug-and-play device.

Baud rates: 300 to 115.2K Baud.

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).
