RS232 to RS422 /RS485 Interface Converter


The ic485IP Interface Converters provide asynchronous conversion between RS-232 interface and RS-485 standard interface. The RS-232 interface connection is via the unit’s DB-25 female connector, while the RS-485 side’s connection is via either a five screw terminal block or an RJ-45. The ic485IP converter’s circuitry is not electrically isolation between the RS-232 and RS-485 sides. The RS-232 side may operate as DTE or DCE, has provisions for establishing hardware flow control, and has LEDs to indicate data transmission and reception. The RS-485 side may operate in either two wire half duplex or four wire half or full duplex and also has LED’s to indicate data transmission and reception.
