Hi Sir,

I have a 4-20mA pressure transducer 0-700 Bar, its 4 wire, two wires for power and other A and B wires goes to RS 485.
I dont know anything how to configure with RS 485. Please help me from begin to End.

Thank you

Hi Prabhakar,

Instead of RS485, you can always use 4-20 mA output.
If you want to use RS485 then please refer to Part K - Communication, sub section SERIAL sensor port and find about RS485 configuration.
A/B naming convention is not standard, so if your sensor have A and B (plus ground) for RS485 then you should try to assume B as positive signal than A.
Thus the connection to dataTaker will be A to TxZ, B to RTS Y and ground to D Gnd.

In case you don't receive any response from the sensor you can swap between A and B connection.
But use this swapping as last resort as most of the time port setting is the cause of connection failure.

Best regards,
