Commissioning
18 Snow depth sensor SHM 31, V2.1
7. Commissioning
7.1. Important information for commissioning
T
he following points must be noted:
Using the RS485 configuration over UMB
• Learn how the UMB ConfigTool.NET software works. The current version of the
software can be downloaded from the Lufft website at:
https://www.lufft.com/download/software-lufft-configtool-net/. The software contains
a Help function that provides further explanations on using the software. A quick start
guide specifically for the SHM 31 forms part of this operating manual.
Laser safety
• Do not look into the laser when the sensor is switched on. To ensure that the laser
is transmitting periodically, use a sheet of paper, for example, and hold it in the laser
beam. Observe the laser beam indirectly!
Mechanical and electrical connection
• Ensure that the SHM 31 has been connected and installed according to its intended
use.

2. Switching on
As soon as the SHM 31 is supplied with power, it starts its internal measuring cycle and can be addressed
over RS232, as well as over RS485 or SDI-12 – depending on the selected setting.
7.2.1. Settings over RS232 or RS485
If you would like to address the SHM 31 sensor over RS232, you can use a terminal program with the UMB-
ASCII protocol. For communication over RS485, you can choose between the UMB-ASCII 2.0 and the UMB
binary protocol. We recommend using the ConfigTool.NET software with UMB binary protocol to conveniently
set up the sensor over RS485. The setting options and parameter lists for operation over UMB-ASCII 2.0 or
UMB binary protocols are listed in the following sections.
7.3. UMB ConfigTool.NET
The ConfigTool.NET software is available for various operating system platforms. It can basically
communicate with sensors over a serial, a Bluetooth or a network interface. ConfigTool.NET allows the
following communication steps:
1. R
eading out the sensor’s individual UMB channels; also see section 9
2. Automatically querying, graphically displaying and storing the measured data
3. Performing firmware updates
4. Controlling the sensor using parameter lists
5. Control commands, such as determining reference values, defrost mode, etc.

3.1. Basic installation with ConfigTool.NET and a serial interface
The following steps can be performed to work with the UMB ConfigTool.NET software during initial
installation:
1. Install and launch the current UMB ConfigTool.NET software
2. Preparatory settings:
a) On the ConfigTool.NET start screen, click on the ‘Settings’ cogwheel icon in the top
r
ight-hand corner.
