Setting fields - WXT530

Parameter	Description
[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.

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

Table 1. Supervisor parameters bits 1-8

Bit	Description
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

Bits 9-16 determine the supervisor parameters included in the composite data message obtained with the following commands:

• ASCII: aR0 and ar0
• NMEA 0183: aR0and ar0
• SDI-12: aM, aMC, aC, and aCC
• SDI-12 continuous: aR and aRC

Bit	Description
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

Parameter	Description
[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 on page 34. Heating disabled: Heating is off in all conditions.
<cr><lf>	Response terminator
