The iTC-5 converts analog (spade connector) transducer signals used in ST60+, i70, ST70+ and ST70 instruments into SeaTalkng sentences for integration into full SeaTalkng backbone systems. Transducers for Speed, Depth, Wind, Rudder Angle and Fluxgate Compass can be connected to one iTC-5 unit, eliminating the need for multiple ST70 pods. Extended SeaTalkng systems can support multiple iTC-5 units. SeaTalkng connections at the base of the unit simply connect the iTC-5 unit to the SeaTalkng backbone. Six LED Status Indicators show integrity of connected transducers and the SeaTalkng network. In an SPX autopilot system the fluxgate compass and rudder reference transducer must be connected directly to the course computer and not the iTC-5.
