2) Factory setting: Even parity, 1 stop bit. Modbus Map see User Manual at www.epluse.com/cds201.

3) Factory setting: No parity, 1 stop bit. Product Implementation Conformance Statement (PICS) available at www.epluse.com/cds201.

Regardless of the model (M11 or M12), RH and Td are also always activated and are available on the BACnet interface.
