KALEA INFORMATIQUE RS232 to RS422 or RS485 converter with DB9 plugs and wired terminal block for RS 485 422 mounting

To link different electronic devices together (for example, in the world of servers, automation, payment terminals, or simply to synchronize a camera and a PC), it is often necessary to convert these two standards. This device is capable of converting RS232 to RS422, extending the maximum distance to 1.2km! Passive, it requires no external power supply (it uses the RS-232 interface for power). Internal circuitry controls the direction of data flow. Interface compatible with EIA/TIA RS-232C and RS-422 standards. RS-232 side: DB9 female connector. RS-422 side: DB9 male connector with additional connection plate for wire-to-wire connections. Operates in Half Duplex Full Duplex RS422 modes. Transfer speed from 300 to 115200 bps. Signals: RS232C: TXD, RXD, RTS, CTS, DTR, DSR, DCD, GND // RS422: D+/A (TX+), D-/B (TX-), RX+, RX-, GND, +5V-+12V. Maximum transmission distance 1200m (RS-422) and 5m (RS-232)
