Appendix 1: Serial commands M210300en

DSEND Outputting readings of all connected transmitters once

DSEND <cr>

All transmitters connected to the serial bus send their addresses and current

measurement readings in a sequence defined by their addresses. After

receiving DSEND command a transmitter sets a delay time according to its

address value and sends the data after this delay. DSEND works also in POLL

mode. With this command the user can, for example, easily find out the

addresses of the transmitters.

The output when four transmitters with addresses 4, 5, 10, 33 have been con-

nected to the serial bus:

>dsend <cr>

4 14.43 %RH

5 22.7 'C

10 14.99 %RH

33 22.3 'C

ERRS Outputting error messages

ERRS <cr>

During operation, error messages are not automatically output through the se-

rial interface. If there is any reason to doubt that there is something wrong

with the transmitter, possible error messages can be output with command

ERRS.

If there are no error messages, only a prompt is displayed:

>ERRS <cr>

If errors have occurred, the transmitter outputs the error code (see Appendix 4

for error messages):

>ERRS <cr>

E40 f ( all ) out of range

1 2 ... 75 76 77 78 79 80 81 82 83 84 85 ... 129 130
