10.5 Initial Settings
The GP-150-DUAL can output navigation information to external equipment
through the Interface Unit IF-2500. For example, it can output position data to a
radar or echo sounder for display on their screen.
Before selecting data to output, confirm what data the external equipment
requires. Output necessary data only. Outputting unnecessary data can cause
receiving problems at the external equipment.
Talker
All data transmitted by marine electronics equipment is prefixed with a
two-character code which tells external equipment what equipment is
transmitting data. This two-character code is called the “talker.” The
GP-150-DUAL contains the talkers GP, LC and DE.
Data format and data output availability
