[CA] [CA11] DST-800 not reporting speed

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum YachtAlia,

Please verify that the DST800 has been interfaced to the iTC-5 in the manner which has been specified within the DST-800 Connection to iTC-5 Instructions. If so, please note that it is normal for the iTC-5's Speed / Temp LED to flash until the iTC-5 senses rotation of the paddlewheel. Once rotation is sensed, the iTC-5's Speed / Temp LED will be illuminated, but no longer flash. Upon being sensed, the iTC-5 may then be selected as the speed source and may be calibrated via an i70S/i70 MFID or Axiom/Axiom Pro/Axiom XL MFD running LightHouse 3 v3.11.42 or later software. Should your iTC-5 not be responding in this manner, then it would be recommended that the iTC-5 be sent to Raymarine’s Product Repair Center to be bench checked / serviced.
