8.4 Outputting Data
Besides its fundamental function of display-
ing position, the DD-80 can also receive data
and output data to external equipment, through
an interface unit. Before outputting data to ex-
ternal equipment, first determine what data
the external equipment requires. Output only
necessary data to ensure 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 DD-80 transmits data using the
GP (GPS talker), Loran (LC) or Decca (DE)
talker.
If the external equipment does not recognize
the GP talker use one it does regcognize, like
LC.

2) Press ▲ or ▼ to select Data Fmt.
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 Tx in-
terval settings entered by the installer of the
equipment should not be changed unless ab-
solutely necessary.
BWC and WNC are for great circle naviga-
tion and BWR and WNR are for rhumb line.
However, all output data are calculated by
rhumb line.
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%.
DATA 3 output setting
The DATA 3 connector can output IEC 61162-
1/NMEA 0183 data or log pulse. For NMEA
0183,IEC 61162-1 the same data output by
DATA 1 is output from DATA 3.
For log pulse, select 200 or 400 pulse per sec-
ond depending on the device connected.
1) Press [MENU ESC] [9] and [3].
2) Press ▲ or ▼ to select DATA 3 or Log
Pulse.
3) For log pulse, press t or s to select log
pulse of external equipment; 200 ppm or
400 ppm.
4) Press the [NU/CU ENT] key twice.
