Sick S3000 Laser baud rate

Hello,

I have a Sick S3000 Laser used primarily for safety function. I would also like to see scan messages using the s3000_laser ROS package.

I have configured the laser using Sick's configuration utility. It now outputs measurements continuously. I am unable to use a baud rate over 38,400 Baud. When I configure the Laser scanner to a higher baud and make corresponding changes in the launch file, I either get

(1) several S3000: Checksum's dont match, thats bad (data packet size ) [ this happens with 125kBaud, 250kBaud], or,

(2) simply no scan messages at all [500 kBaud].

I am using a regular Serial port configured as an RS-422 port on the computer (not a USB-RS422 adapter). The maximum freq of messages is about 2.5 Hz which is super low.

Am I missing something? Should I do something more to achieve better baud rates? Any help is greatly appreciated.

Thank you.

Have you configured the baud rate using the CDS software?
