ID address, baud rate, parity and stop bits can be set via:
1. EE-PCS, Product Configuration Software and the appropriate configuration cable.
2. Modbus protocol in the register 60001 (0x00) and 60002 (0x01). See Application Note Modbus AN0103
(available on www.epluse.com/ee210)
The measured values are saved as a 32 bit float value and as 16 Bit signed integer, see the Modbus Register map below.
The serial number as ASCII-code is located at read register address 30001-30008 (16 bit per address).
The firmware version is located at register address 30009 (bit 15...8 = major release; bit 7...0 = minor release).
The sensor name is located at register address 30010.

1) Register number starts from 1
2) Register address starts from 0
3) The choice of measurement units (metric or non-metric) must be done in the ordering guide, see EE210 data sheet.
Switching from metric to non-metric or vice versa by using the EE-PCS is not possible.
4) 100 is scale 1:100 (2550 is equivalent to 25.5 °C)
5) If the ID is set via DIP-switch the response will be NAK
6) For Modbus protocol settings please see Application Note Modbus AN0103 (available on www.epluse.com/ee210)
