Pioneer P3DX SICK Lidar LMS111 not getting connected [closed]

edit

I am using SICK Lidar LMS 111 on a Pioneer P3DX robot. I am using the Aria demo program to verify the initial setup to verify everything is communication properly or not. But when I am using the LIDAR mode, I am getting an error message as listed below.

ArConfig: Config version: 2.0
Loaded robot parameters from /usr/local/Aria/params/p3dx-sh.p
Robot Serial Number: GMC_4091
ArRobotConnector: Connecting to MTX batteries (if neccesary)...

I have verified the LIDAR IP address using SOPAS tool and it is 192.168.12.97. I have connected the LIDAR to eth0 of my on-board computer.

I have edited the p3dx-sh.p , p3dx.p and p3dx-sh-lms1xx.p files under /usr/local/Aria/params.

LaserType lms1xx                     ; Type of laser.
LaserPortType tcp                     ; Type of port the laser is on.
LaserPort 192.168.12.97            ; Port the laser is on.

But still my Lidar is not getting connected.

Please help me to resolve this issues

Thanks
