Page 8: Configuration
ENVIROsense ETS series – Environmental transmitters V1.0 4 Configuration The configuration of the transmitter can be done: • By sending serial commands from a PC, via a standard communication program (see the chapter “ASCII proprietary protocol”). • Via the “Holding Registers” in Modbus-RTU mode (see the chapter “Modbus-RTU protocol”). -
Page 9: Ascii Proprietary Protocol
ENVIROsense ETS series – Environmental transmitters V1.0 5 ASCII proprietary protocol To communicate with the transmitter via the ASCII proprietary protocol: 1. Connect the transmitter to the PC and start a standard serial communication pro- gram. 2. In the serial communication program, set the Baud Rate 57600, the parameters 8N2 and the COM port number to which the transmitter is connected. -
