The red light is ok (laser is running in some kind of service mode).
Is there any source of transformation for laser frame ? It is required for rviz to work propertly.

Finally I can connect to my LMS111, all I do is I change the IP of my PC so that PC can find my laser scanner. For example my PC IP address is 169.254.250.1 and laser scanner address is 169.254.250.176. And this is a output when I execute rosrun LMS1xx LMS100tienthanh@tienthanh-pc:~$ rosrun LMS1xx LMS100[ INFO] [1298985619.706064737]: connecting to laser at : 169.254.250.176[ INFO] [1298985619.706668553]: Connected to laser.But after connect to laser, in laser scanner the red light turns on. I'm not sure if it is OK because I see nothing when run rvix an connect the topic /scan in rviz. And I got this warning:

Please turn the [ros.rviz.message_notifier] rosconsole logger to DEBUG for more information.I think the problem comes from the configuration of rviz, anyone have idea to solve it?--On Mon, Feb 28, 2011 at 11:46 PM, Tien Thanh <nttputus@gmail.com> wrote:
I am using this with static address assigned (192.168.1.2) it's look like you are using it with some kind of "automatic address".I thought so. I took the IP from SOPAS software in windows. I guess that automatic address created by windows. Should I edit IP address for laser scanner manually (to 192.168.1.2?) in SOPAS before connect it to ROS? Otherwise Linux can't find the IP address of laser scanner automatically.That "automatic address" looks suspiciously like what you get when a computer is configured to use DHCP but there is no DHCP server available, so it defaults to something like that. Is the laser configured to use DHCP to get it's address but there are no DHCP servers available on the same LAN as it?- Eric
Are you using latest version from : https://github.com/RCPRG-ros-pkg/RCPRG_laser_drivers ?
