72 Serial Communication and Command Set
Broadcast Mode – NMEA183GLL
Command: 0,nB
0,nB configures the clock to broadcast the National Marine Electronics Association Standard
(NMEA - 0183) to broadcast from the main RS-232 port, where n = the update rate in seconds,
from 1 to 9999.
GLL - Geographic Position, Latitude-Longitude
Latitude and Longitude of present vessel position, time of position fix and status.
Response: $–GLL,llll.llll,a,yyyyy.yyyy,a,hhmmss.sss,A*cs
C
Where: GLL = Geographic Position, Latitude / Longitude
llll.llll = Latitude of position
a = N or S
yyyyy.yyyy = Longitude of position
a = E or W
hhmmss.sss in UTC
A = status: “A” is Active, “V” is Void
*cs = checksum
Broadcast Mode - NMEA183ZDA
Command: 1,nB
1,nB configures the clock to broadcast the National Marine Electronics Association Standard
(NMEA - 0183) to broadcast ZDA format from the main RS-232 port, where n = the update
rate in seconds from 1 to 9999. ZDA, time and date, includes the UTC day, month, year, and local
time zone.
Response: $–ZDA,hhmmss.ss,dd,mm,yyyy,±xx,xx,*cs
C
Where: ZDA = Time and date
hhmmss.ss = Time in UTC
dd = Day, 01 to 31
mm = Month, 01 to 12
yyyy = Year
±xx,xx = Local zone description, 00 to +/- 13 hours and minutes
*cs = checksum
Broadcast Data – ABB SPA MSG
Command: 0,nTB
0,nTB configures the clock to broadcast the ABB SPA format from the main RS-232 port, where
n = the time zone; time reported is in UTC format for n = 0, and Local format for n = 1.
The ABB SPA time string is a sequence of 32 ASCII characters starting with the characters
>900WD and ending with the carriage return character. The letters printed in italics are replaced
by ASCII numbers whereas the other characters are part of the time string.
