The RS-232 to RS-485 Serial Converter for the KilnScout converts a full-duplex RS-232C port to a half-duplex two-wire RS-485 port. A built-in data direction auto-turnaround feature automatically enables the RS-485 driver when data is present from the RS-232 port, eliminating the need for software drivers, and making the device fully plug-and-play. The unit is enclosed in a rugged ABS housing, and is powered from the RS-232 data lines; no external power is required. This converter operates from 300 to 115,200 bps.
