APPENDIX 3 DIGITAL INTERFACE
TLB - Target label
$--TLB,x.x,c--c,x.x,c--c,...,x.x,c--c*hh<CR><LF>
1 2 3
1. Target number "n" reported by the device
2. Label assigned to target "n"
3. Additional label pairs
Comments:
1) This sentence allows several target number/label pairs to be sent in a single message,
the maximum sentence length limits the number of labels allowed in a message.
2) Null fields indicate that no common label is specified, not that a null label should be
used. The intent is to use a null field as a place holder. A device that provides tracked
target data should use its "local" label (usually the target number) unless it has
received a TLB sentence specifying a common label.
TRC - Thruster control data
$--TRC,x,x.x,a,x.x,a,x.x, a,a*hh<CR><LF>
1 2 3 4 5 6 7 8
1. Number of thruster, bow or stern (0 to 9)
2. RPM demand value (-999.9 to 999.9)
3. RPM mode indicator (P=per cent R=revolutions per min
V=data invalid)
4. Pitch demand value (-180.0 to 180.0)
5. Pitch mode indicator (P=per cent D=degree V=data invalid)
6. Azimuth demand (000.0 to 359.9)
7. Operating location indicator (B=bridge P=port wing S=starboard wing
C=engine control room E=engine side/local W=Wing)
8. Sentence flag status (No use)
TRD - Thruster response data
$--TRD,x,x.x,a,x.x,a,x.x*hh<CR><LF>
1 2 3 4 5 6
1. Number of thruster, bow or stern (0 to 9)
2. RPM response (-999.9 to 999.9, null)
3. RPM mode indicator (P=per cent R=revolutions per min
V=data invalid)
4. Pitch response value (-999.9 to 999.9, null)
5. Pitch mode indicator (P=per cent D=degree V=data invalid)
6. Azimuth response (000.0 to 359.9, null)
TTD - Tracked target data
!--TTD,xx,xx,x,s--s,x*hh<CR><LF>
1 2 3 4 5
1. Total hex number of sentences need to transfer the message (1 to FF)
2. Hex sentence number (1 to FF)
3. Sequential message identifier (0 to 9)
4. Encapsulated trancked target data (6 bit binary-converted data)
5. Number of fill bits (0 to 5)
