• Set the address of the transmitter; you can choose any number

between 1 and 99. In this example the address is 22:

>addr 22

Address : 22

• Set the serial bus settings according to your network specifications.

This setting will become valid after next RESET or power off:

>seri 2400 e 7 1 h

• Set the transmitter in POLL mode:

>smode poll

Serial mode : POLL

NOTE 1

The SMODE command must be given last.

NOTE 2

The transmitter outputs no prompt (>) after the SMODE

POLL command and it only reacts to commands which

include its address.

• Check that the transmitter responds to its address:

send 22

RH= 24.4 %RH T= 29.1 'C

• Disconnect the terminal.

• Remount the digital current loop module.

• Close the cover.

• When all transmitters on the network have been configured, switch

them off.
