About cNODE transponders
cNODE® is a series of transponders for underwater acoustic positioning and data link. They have more than 500 channels available, and can all be positioned by HiPAP® underwater positioning systems. Each
underwater target to be positioned must have a transponder or a responder installed. The transponder operates acoustically while the responder requires a cable for triggering. The new cNODE® range of transponders are backwards compatible
with the older FSK channels and telemetry protocols and can therefore be used by any HPR400 and HiPAP® systems.
Cymbal and compatibility
The new cNODE® range of transponders are compatible with the older HPR400 and HiPAP® FSK channels and telemetry protocols. The new HiPAP® 502/452/352/351P/102 systems can also optionally work with the Cymbal acoustic protocol for more accurate positioning and high speed data link (up to 8000 bits/second). Ranges can be measured with 0,01m accuracy and over longer distances due to more energy in the signals.
