Setting Fields
[R] = Parameter selection: This field consists of 16 bits
defining the supervisor parameters included in the
data messages. The bit value 0 disables and the bit
value 1 enables the parameter.
The bits 1-8 determine the
parameters included in the
message obtained with the
following commands:
-ASCII: aR5 and ar5
-NMEA 0183: $--WIQ,XDR*hh
-SDI-12: aM5, aMC5, aC5, and
aCC5
-SDI-12 continuous: aR5 and
aRC5
1st bit (most left) Th Heating temperature
2nd bit Vh Heating voltage
3rd bit Vs Supply voltage
4th bit Vr 3.5 V reference voltage
5th bit Id Information field
6th bit spare
7th bit spare
8th bit spare
& delimiter
The bits 9-16 determine the
supervisor parameters
included in the composite data
message obtained with the
following commands:
-ASCII: aR0 and ar0
-NMEA 0183: aR0, ar0
-SDI-12: aM, aMC, aC, and aCC
-SDI-12 continuous: aR and
aRC
9th bit Th Heating temperature
10th bit Vh Heating voltage
11th bit Vs Supply voltage
12th bit Vr 3.5 V reference voltage
13th bit Id Information field
14th bit spare
15th bit spare
16th bit (most right) spare
[I] = Update interval: 1 ... 3600 seconds. When the
heating is enabled the update interval is forced to 15
seconds.
[S] = Error messaging: Y = enabled, N = disabled
[H] = Heating control enable: Y = enabled, N = disabled
Heating enabled: The control between full and half
heating power is on as described in Heating
(Optional) on page 29.
Heating disabled: Heating is off in all conditions.
