Cable link converter RS 232-485

The 232-485 converter cable link transforms a serial communication from RS232 standard to RS485 standard.

For the RS485 standard the communication is half duplex type on 2 conductors (+ mass) and the communication sense is managed automatically. The RS232 signal is optically isolated from the RS485 signal and moreover, through the DTR (PIN4) signal coming from the RS232 connector or through a card jumper (JP2), the RS485 cable can be disconnected by means of relays.

CABLELINK is supplied with external power supply and power cord for 230Vac operation; the RS232 cable coming out of CABLELINK with DB9 female can be directly connected to a PC's standard RS232 serial port. On the front panel there are LEDs that indicate the status of
operation of CABLELINK.
