  • Adds support for CMV4000 imagers (2048x2048.)
  • Many small bugfixes and feature enhancements.

Please note this firmware release is only supported for MultiSense-SL and S7 units.

To upgrade an existing MultiSense-SL, first download and build the latest ROS driver from github:

Detailed instructions on how to do this can be found in section 1.2 of the attached document, MultiSense-SL ROS Driver_v2.3.pdf.

If you are upgrading an existing ROS driver installation, make sure to issue a "--pre-clean" directive when rebuilding:

$ rosmake --pre-clean multisense

After building the latest ROS driver, your MultiSense-SL can be field upgraded to v2.3 firmware by downloading the multisense_firmware_v2_3_1.slf file and issuing the following command from the ROS driver environment:

$ rosrun multisense_lib MultiSenseUpdater multisense_firmware_v2_3_1.slf

(assuming the IP address of the MultiSense-SL is "")

WARNING: Before upgrading, please refer to section 2.5.6 of the MultiSense-SL ROS Driver_v2.3.pdf document for important instructions regarding the use of the MultiSenseUpdater utility.
