Appendix 4: Digital current loop module HMP260-U017en-1.5

• 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.

Dual loop operation

Single pair/dual pair use is configured through wiring (see figure on page 2).

The following procedure must be repeated with all transmitters.

• Open the transmitter cover.

• Pull out the digital current loop module, if it is already mounted.

• Set the serial port of the terminal to 4800 baud, even parity, seven data bits

and one stop bit, full duplex (4800 E 7 1 FDX).

• The serial settings of the transmitter must also be 4800 E 7 1 FDX and the

transmitter must be in STOP mode. If these factory settings have been

changed, they must be changed back. Connect the RS 232C port of the

terminal to connector X17 on the top of the main board and switch the power

on.
