●SDI-B SIGNAL DISTRIBUTION INTERFACE（2 to 10 ）：
1) POWER: 9～30VDC；
2) INPUT 2 CHANNELS 4800 baud NMEA 0183 format
The primary navigation aid is normally connected to channel 1 input and a secondary navigation aid can be connected to channel 2
OUTPUT: 10 CHANNELS 4800 baud NMEA 0183 format
3) Two Navaids may input their data but in the "auto mode" only the priority channel 1 will output the data with fail-safe to channel 2.
SDI-B also artificial freedom select channel 1 or channel 2. ensure your data transmission security and steady.
4) SDI-B can be used for distributing GPS and gyro data to a multitude of equipment .
