A5022
A5022
The document specifies the shipping weight for different models of the A5022 compass, ranging from 120g to 1.0kg. It also outlines parameters such as time to valid output (tPU) and output error (ERROP) under specific conditions.
The A5022 compass is IP68 rated and connects directly to the A5500. It supports NMEA-0183 and Furuno/SPI protocols, with 2-axis tilt compensation up to 45 degrees. The device operates on a supply voltage of 8-30 V and includes features like a rich command set, rate-of-turn sentence (HFROT), auto calibration, and a set zero button.
This compass is suitable for marine and vehicle navigation, radar systems, autopilots, AIS, and off-course alarm systems.
The storage temperature range is -20 to +100°C, while the operating temperature range is -20 to +60°C at 12V. It can withstand a shock resistance of ±40 G and vibration resistance of ±11 G at 60Hz. The supply voltage can reach up to 30 Vdc at 40°C, and the operating pressure range is -0.5 to +2 Bar.
At 20°C, the supply voltage ranges from 8 to 30 Vdc, with a typical current consumption of 25 mA. The NMEA output load supports up to 4 NMEA loads, and the Furuno output load is 1 mA.
The compass outputs standard NMEA-0183 sentences, configurable in several forms, such as $HCHDG and $HCHDT, with a magnetic heading precision of 0.1 degrees. The serial output is RS422, 4800 Baud, with 8 data bits, 1 stop bit, and no parity.
Commands include starting/stopping auto-calibration, resetting calibration data, setting reference heading, heading damping, and NMEA-0183 output sentence interval. Additional commands manage LED status, sentence structure, checksum, serial number, autocal status, and power-up delay.
The document lists the pin connections for power, output, input, and signal, including specific color codes for each function.

ELECTRICAL CHARACTERISTICS AT 20°C PARAMETER NMEA-0183 OUTPUT FORMAT (software subject to change) The output from the compass is a standard NMEA-0183 sentence which can be configured to be in one of several standard forms: Eg: $HCHDG,hhh.h,,,,*ss<CR><LF> or $HCHDT,hhh.h,T<CR><LF> where hhh.h represents the magnetic heading with one decimal place of precision, i.e: 000.0 to 359.9 degrees. The two HEX digits, ss, are a checksum. Serial output is RS422, 4800 Baud, 8 data bits, 1 stop bit, no parity. An option is to include $HFROT,zxxx.x,A*cc<CR><LF> The compass may be configured via several proprietary...
