RS-232 to RS-485 Converters

RS-232 to RS-485 Converters

DFRobot’s TEL0038 and TEL0123 series are RS-232 to RS-485 converters that are self-powered, bi-directional adapters. They are designed to convert a full-duplex RS-232 signal to a half-duplex RS-485 balanced differential signal and extend the communication distance to up to 1.2km. These RoHS-, CE-, and FCC-certified converters each feature a RS-232 DB-9 female connector and a RS-432 DB-9 male connector. Both components include a 4-position terminal block, which can be attached to the RS-485 port to provide screw-lug wire terminations for the port. The TEL0123 converter includes an additional 3-position terminal block that can be attached to the RS-232 port.
