which is part of the delivery. It can also be downloaded from the ASTECH website. The standard baud rate of the 
VLM60 is 115200baud (8N1). 

For the installation of the driver, Windows must be fully started and the VLM60 must not be connected to the 
PC. Now the driver installation (an executable EXE file) can be done. Afterwards the VLM60 can be connected to 
the PC. It is recommended to connect the cable end to the VLM60 first and then the other cable end to the PC. 
Windows  should  now  recognize  the  new  hardware  and  use  the  previously  installed  FTDI  driver.  When  the 
installation is complete, a new COM port will appear in the Ports section of the Windows Device Manager. This 
COM port must be selected later when using the VLMTool for communication. 

 

 

Programming cables can be obtained in various lengths from the manufacturer.

Signal-LED 

There is a two-color LED in the lid of the VLM60. This indicates the current operating state of the device. Table 4 
shows the possible states. 

 

Color 

Light condition 

Event 

Red 

continuous or 
blinking 

Very bad measurement condition, 
very bad motion detection 

Orange 

Continuous or 
blinking 

Moderate  measurement  condition, 
moderate motion detection 

Green 

Continuous or 
blinking 

Optimal measurement condition, 
optimal motion detection 

Table 4: Light conditions of the signal LED 

 

Furthermore, serious internal error faults are represented by a red pulse sequence. In this case, the manufacturer 
needs to contacted.

Maintenance and Cleaning 

The VLM60 is maintenance-free. For proper and long-lasting operation, the viewing window should be checked 
at regular  intervals  and, if necessary, cleaned of dirt.  If the viewing window is cracked  or broken, it must  be 
replaced. The replacement is carried out exclusively by the manufacturer. 

A damp, lint-free cloth should be used to clean the viewing window. If the viewing window is very dusty, it is 
recommended to remove the dust particles with compressed air or a brush beforehand to avoid scratches on 
the glass.  Do not use any aggressive agents for cleaning. 

 

 

 

If the VLMTool is installed, the user is automatically offered to install the IUSB driver as well. For this 
purpose, it is recommended not to connect the VLM60 to the PC. The VLM60 may only be connected 
to the PC after the VLMTool and driver have been completely installed.
