X COMMAND DEFINITION RESPONSE AND DETAILS
xGPDT!
Get peak detector
type
Response: a+t
In which “t” = the peak detector type:
0 – report the distance to the maximum peak which
corresponds to the maximum radar signal reflection
1 - report the last peak which corresponds to the furthest
reflection from the radar; this may include multipath
reflections in typical cases and should be avoided
xGPDT+t!
Set peak detector
type
Replace “t” with desired peak detector type code (see codes
above in “Get peak detector type”.
Response:
a+t
xGBKG+d!
Save background
signal level
Response: a+d
n which “d” = distance in currently used units
Stores the radar echo curve signature from zero distance up to
defined distance “d”. The stored echo curve is used as a
reference signal background level, and only reflections
stronger than the saved level will be used when searching for
the water level. To clear this setting, send this command with a
parameter d set to 0 (zero).
xGLWU!
Wake up from
sleep mode
Response: a+0
When the instrument is configured to operate in SDI-12 mode,
it goes to sleep until SDI-12 measure command (aM!) is issued.
Connection to the instrument through RS-232 and RS-485
interfaces is not possible while the instrument is in the sleep
mode. To facilitate connecting to the instrument from the PC
application, after issuing this command, the instrument will
wake up and remain in active state for 60 seconds. During that
time, a connection over serial cable can be established using
the Instrument Configurator PC application. If the connection
is established within this 60-second period, the instrument will
remain in the active state as long as the PC application is
connected to the instrument.
xGCLR!
Clear the stored
radar calibration,
perform self-
calibration, and
store new
calibration
parameters.
Response: a+1
Forces the instrument to clear the stored radar calibration,
and to perform the self-calibration again. In majority of cases
the factory calibration will be valid through the whole lifetime
of the instrument, and there will be no need to redo the self-
calibration.
