Transponder, cNODE Micro

The cNODE® Micro transponder rated to 600 meters, is small and light enough to be used by divers and shallow water ROV's. Operating on KONGSBERG Cymbal digital acoustic protocols the cNODE Micro provides the optimal positioning performance with the KONGSBERG range of SSBL systems from µPAP® through to HiPAP®.

The telemetry capability allows the battery status to be read during operation and the integrated tilt sensor can be turned on and off with positioning updates. Multiple cNODE® Micro transponders can be interrogated simultaneously in SSBL positioning mode using the µPAP® and HiPAP® Fast track feature to ensure the fastest possible updates during operation.
