Table 3 – DST-2 specications
All specications are taken with reference to an ambient temperature (T
A
) of +25°C.
Note:
1. The maximum quoted currents are for very short periods (less than 0.5 milliseconds) only.
2. NMEA output is RS-485 compatible.
3. NMEA 0183 inputs and outputs on the DST-2 are xed to 4800 baud. Custom Baud rates and custom data rates
are available if required for specialised installations.
