Is the URM08-RS485 sensor modbus correct working?

If I send a HOLDING_REGISTER 2 distance I get always the same response
11 03 00 02 00 01 27 5a -→ 11 03 02 01 11 b8 1b

and with HOLDING_REGISTER 3 temperature
11 03 00 03 00 01 76 9a -→ 11 03 02 01 11 b8 1b 00 00 00 00 00 0e c6 00 01 02 02 00 00…. up to 255 bytes

Do I need different register?

Thanks

Got it working. Only the distance with register 01

Hi ThijsH,

Can you explain how you got the sensor to work? Or how you determined that you had to use register 01 instead of 02?

Much appreciated
