19.9 (WS100-UMB only) Communication: UMB-ASCII 2.0 Protokoll
UMB-ASCII 2.0 provides query of measurement values and sensor configuration in a human
readable format. Details and general commands can be found in the UMB-ASCII 2.0 manual
(Manual_Lufft_UMB-ASCII_2_0_Version_1_1_en.pdf).
The separators used for the output strings can be adjusted to the requirements of a logger
(see Chapter 0)
In addition to the general configuration commands described in the UMB-ASCII 2.0 manual
device specific commands for configuration work have been defined for the WS100-UMB
(see Chapter 19.9.2)
In UMB-ASCII 2.0 mode defined sets of measurement values can be transmitted
automatically at adjustable intervals without further query commands. WS100-UMB provides
four standard sets:
- S1: General precipitation values, metric units
- S5: General precipitation values, imperial units
- S10: Service channels (drop distribution, air temperature), metric units
- S15: Service channels (drop distribution, air temperature), imperial units
19.9.1 Format of the Standard Sets
The following list uses UMB-ASCII 2.0 factory setting separators.
