How to interface with the UST series Hokuyo Laser Scanners

How to interface with the UST series Hokuyo Laser Scanners (Call us at 4165082574 if more questions)


1.     Power the unit by connection the BROWN wire to +12V and the DARK BLUE wire to ground of a DC 12V (300mA or more is recommended) power supply.


2.     Leave other wires unconnected.


3.     The default IP address is Port number: 10940.


4.     URG Benri data viewing tool can be downloaded from the following link.



5.     Please refer to the SCIP 2.2 communication protocol of the UTM-30LX-EW.


2.     The Hokuyo UST-10LX and UST-20LX supports most of SCIP 2.2 commands for the UTM-30LX-EW.


6.     If you have a program for the UTM-30LX-EW and the program uses only single-echo commands, the program can be used with the UST-10LX and UST-20LX with minimum or no changes.
