3) Press t or s to select NMEA 0183
(V1.5 or V2.0) or IEC 61162-1.
4) Press the [NU/CU ENT] key. Talker ID
appears in reverse video.
5) Press t or s to select GP, LC or DE.
6) Press the [NU/CU ENT] key.
7) Enter Tx interval for each output data sen-
tence in line 1. Tx interval is available in
00, 01, 02, 03, 04, 05, 06, 10, 15, 20, 30,
60 and 90 (seconds).
8) Press the [NU/CU ENT] key.
9) Enter Tx interval for each output data sen-
tence in lines 2 through 5. Press the [NU/
CU ENT] key after setting each line.
For detailed information about Tx interval see
the installation manual. However, the settings
entered by the installer of the equipment
should not be changed unless absolutely nec-
essary.
BWC and WNC are for great circle naviga-
tion and BWR and WNR are for rhumb line
navigation.
The total data output are shown by percent-
age on the third line. For best results the total
output should not exceed 90%; lengthen the
Tx interval of less important data to make the
total output less than 90%.
When the external equipment cannot display
correct data input from the GP-80, the rate of
operation should be lowered.
For example, set a rate of operation less then
60% for the Temoerature Indicator TI-20.

Besides its fundamental function of display-
ing position, the GP-80 can also output vari-
ous data to external equipment. Before
outputting data to external equipment, first
determine what data the external equipment
requires. Output only necessary data to en-
sure data will be output correctly.
All data transmitted by marine electronics
equipment are prefixed with a two character
code called a talker. The same talker must be
shared by the transmitting and receiving
equipment to transmit and receive data suc-
cessfully. The GP-80 transmits data using the
GP (GPS talker), however it can also trans-
mit using the Loran (LC) or Decca (DE) talker.
Because the GP talker is a relatively new sys-
tem some early model equipment may not
recognize this talker.
