Note: Do
not
send
“
aXC!
”
(without the
„
n
‟
value) in an attempt to query for the current Auto-Start
setting. This will actually enable the Auto-Start mode!
“aXDn!” Set Liquid Output
This LTI-proprietary SDI-12 extended command configures the second parameter of the Liquid Setting.
This corresponds to the second parameter of the
“
$OS,f,z,0,y
”
serial command.
Command:
Example:
8XD2!
8D2<CR><LF>
The sensor is set to 2 measurements per second.
Note: Sending
“
aXD!
”
(without the
„
n
‟
value) can be used to query for the current measurement mode
setting.
“aXEn!” Set Advanced Filter
IMPORTANT:
Must always be set to zero for proper operation.
This LTI-proprietary SDI-12 extended command configures the third parameter of the Liquid Setting.
This corresponds to the third parameter of the
“
$OS,f,z,0,y
”
serial command.
Command:
Example:
8XE0!
8E0<CR><LF>
The sensor is set to default value of zero.
Note: Sending
“
aXE!
”
(without the
„
n
‟
value) can be used to query for the current liquid advanced filter
setting.
“aXFn!” Set Running Average
This LTI-proprietary SDI-12 extended command configures the fourth parameter of the Liquid Setting.
This corresponds to the fourth parameter of the
“
$OS,f,z,0,y
”
serial command.
Command:
Example:
8XF0!
8F0<CR><LF>
The sensor is set to default value of zero.
Note: Sending
“
aXF!
”
(without the
„
n
‟
value) can be used to query for the current running average setting.
“aXGn!” Number of Consecutive Errors
This LTI-proprietary SDI-12 extended command configures the number of consecutive errors before
reporting an error. This corresponds to the $CE serial command.
