RS232 to RS485 converter With mounting plate

RS232 to RS485 converter Complete, with insert plate
Use:
To link different electronic devices together (for example, in the world of servers, automation, payment terminals, or more simply to synchronize a camera and a PC), it's often necessary to convert these two standards. This device is capable of converting RS232 to RS-485, extending the maximum distance to 1.2km! Passive, it requires no external power supply (it uses the RS-232 interface to power itself). Internal circuitry controls the direction of data flow. When using RS-232, the software will behave as in RS-485 without any change.
Specifications:
Interface compatible with EIA/TIA RS-232C and RS-485 standards.
RS-232 side: DB9 female connector.
RS-485 side: DB9 male connector with additional connector plate for wire-to-wire connections.
Function modes: Asynchronous / Half Duplex / Differential Transmission.
Transmission via twisted pair or shielded twisted pair (STP) cords.
Transfer speed from 300 to 115200 bps.
Signals: RS232C: TXD, RXD, RTS, CTS, DTR, DSR, DCD, GND / RS485: D+/A, D-/B, GND, +5V-+12V.
Maximum transmission distance 1200m (RS-485) and 5m (RS-232). Dimensions: 95mm x 33mm x 17mm.
