1All specifications subject to change without notice. Specifications calculated with the default settings and filters enabled. Kmph and knots are only available when using NMEA 0183 mode.

2Refer to user manual for further details.

3A suitable PSU capable of providing up to 0.2A maximum is recommended. RS422 current load is dependent on topology and resistor values – RS422 in ‘always enabled’ mode may draw higher currents. Refer to the user manual for further details.

4 Requires user calibration, refer to the user manual for further details.
