NM-AD10PC

NMEA-0183 to Furuno AD-10 Converter

Introduction

The NM-AD10PC is an NMEA-0183 to Furuno AD-10 protocol converter.
The NM-AD10PC can be used to interface any gyrocompass or heading sensor device capable of producing NMEA-0183 sentences with all the Furuno instruments that require AD-10 signals as input to acquire the heading information. 
  

Operation

The NM-AD10PC acquires the NMEA-0183 sentences from the Ina port and converts them to a Furuno AD-10 signal which is a two line synchronous serial signal consisting of a clock/shift line and a data line.

The NM-AD10PC can also be configured to function as an AD-10 and NMEA-0183 output signal generator without the need of any input. This mode can be used while connecting to a radar or troubleshooting a faulty interfacing on-board.
 

Input

The user can select the NMEA-0183 source sentence that will be converted to Furuno AD-10 via a dip switch array.  The NMEA-0183 input sentence should be one of the $--HDT, $--HDG, $--HDM, $--VHW and $--RMC. If a multiplexed input is applied containing more NMEA sentences, only the selected sentence will be processed and converted to the Furuno AD-10 format. 
 

Outputs

The NM-AD10PC  converts the heading value acquired from any of the $--HDT, $--HDG, $--HDM, $--VHW and $--RMC into a $HEHDT,xxx.x,T*<CR><LF>  NMEA-0183 sentence that is transmitted via the RS-422 output port.
The current configuration of the selected input sentence is visually represented from the LED B0, B1 and B2 in the front panel of the NM-AD10PC. The transmission of the signals in the AD-10 and NMEA output port and the correct acquisition of the configured NMEA-0183 sentence in the input are also indicated via the TX and RX LEDS respectively.

The output rate of the AD-10 and NMEA-0183 ports can be configured via the dip switches and can either follow the input rate or be fixed at 5Hz. The later is suggested to be used when acquiring the heading data from a “slow” input sentence such as the $--VHW and $--RMC.
