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

• Interface compatible with EIA / TIA RS-232C and RS-485 standards. RS-232 side: female DB9 type connector. RS-485 side: male DB9 type connector with additional connection plate for wire to wire connections. Functions in the following modes: asynchronous / half duplex / differential transmission
• Transmission through "twisted pair" or "shielded twisted pair" (STP) cords. Transfer speed from 300 to 115,200 bps. Signals: RS232C : TXD, RXD, RTS, CTS, DTR, DSR, DCD, GND / RS485: D + / A, D-/B, GND, +5 V - + 12 V. Maximum transmission distance: 1,200 m (RS-485) and 5 m (RS-232). Dimensions: 95mm x 33mm x 17mm
• To interconnect different electronic devices (for example, in the world of servers, automation, payment terminals, or more simply for synchronising a camera and a PC), it is often necessary to convert these two standards. This device is capable of converting RS232 to RS-485 by extending the maximum distance to 1.2 km. Being passive it requires no external power source (it used the RS-232 interface for its power supply). The internal circuit controls the direction data flows. By using RS-232, the software will operate like a RS-485 without any change.

Specification & Features Compatibility: EIA/TIA RS232C standard and RS485 standard Interface RS232 side: DB9 female connector.
