  • EXTRA-1
  • Long Range

To determine the signal line "A" and "B" 

Use a digital voltmeter to measure the voltage across the signal line with respect to 
ground. If the voltmeter shows a negative voltage, then the line on which the
measurement is taken  belongs to the category "A", the positive voltage indicates a signal 

line "B". If the voltmeter is not - simply connect to the device and check the correctness of the data arrival, if the data does not arrive - change the polarity.

IMPORTANT: When connecting several external devices, it is recommended to install the NMEA splitter to amplify the signal and prevent the port from failing

MORE IMPORTANT: For violations in the operation of the equipment it is recommended that this work be performed by a specialist.
