Ottawa,
IL – Optical
isolation and traffic indicating LEDs are just two of the advanced
features that define this new RS-232 to RS-422 or RS-485 data interface
converter. By converting the RS-232 PC output format to RS-422 you
can communicate up to 4,000 feet, compared to the 50 feet normally
reached. Using the RS-485 signal, you may use up to 32 drops on a
two-wire system and use the Automatic Send Data Control which lets
the hardware control the drivers, eliminating software overhead.
