HMP228 Transmitters
Appendix 1: Serial commands
M210282en-A

If errors have occurred, the transmitter outputs the error code (see Appendix 5
for error messages):
>ERRS
E40 f ( all ) out of range
>
ECHO
Turning the serial interface echo ON/OFF
ECHO xxx
xxx
=
ON or OFF
When the echo is off, the commands given through the serial interface or the
prompt > cannot be seen on the display.
When the serial interface is in half-duplex mode, the echo is always off. Even
then the ECHO command can indicate that echo is on.
INTV
Setting the output interval for the RUN state
INTV xxx yyy
xxx
=
output interval (0...255)
0: no pause between outputs
yyy
=
unit (s, min or h)
Sets the output interval when the transmitter outputs measurement readings to
a peripheral device.
For example, the currently valid settings are output with:
>INTV
Output intrv. : 0 min
When this is changed into 10 minutes, the command is:
>INTV 10
Output intrv. : 10 min
The unit is changed into seconds with:
>INTV S
Output intrv. : 10 s
The change can also be done with one command:
>INTV 10 S
Output intrv. : 10 s
