6. INITIAL SETTINGS
Input/Output Setting
The GP-150 can output navigation information to external equipment. For example, it can
output position data to a radar or echo sounder for display on their display screen. You can
convert a Loran Plotter to a GPS Plotter with position data from the GP-150.
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 contains the talkers GP, LC and DE.
Because GPS is a relatively new system some early model equipments do not recognize
the GP talker name. In this case transmit data using a conventional talker, which equipment
recognizes, such as Loran C.
