5. INPUT/OUTPUT DATA 
 
 

The main method for transferring data between a sensor and the Chart Processor Unit is 

IEC 61162-1 Ed.1 or IEC 61162-1 Ed.2 Standard serial communication link. 

In the standard configuration, the system has one serial communication channel interface, 

LAN adapter type EC-1010, to communicate with up to eight external devices in serial 

format. As an option, second LAN adapter can be connected for max. 16 serial channels in 

total. 

Optionally the Chart Processor Unit can be interface to analog signals through a B adapter 

type EC-1020.    For communication with Chart Processor Unit this analog adapter use, one 

serial channel from the LAN adapter. 

 

•  One serial input type of dual-axis speed log ( IEC 61162-1 Ed.1 or Ed.2 message 

$XXVBW.... or NMEA V1.5 message $PKVBW… or NMEA V1.5 message $PSALL, min 1 

message per 2 seconds). 

•  Two positioning equipment can be connected using one of the following communication 

protocols: 
•  IEC 61162-1 Ed.1 messages $XXGLL, $XXVTG and $XXZDA 
•  IEC 61162-1 Ed.1 messages $XXGGA, $XXVTG and $XXZDA 
•  IEC 61162-1 Ed.2 messages $XXDTM, $XXGLL, $XXVTG and $XXZDA 
•  IEC 61162-1 Ed.2 messages $XXDTM, $XXGGA, $XXVTG and $XXZDA 

• 

Notes: 
•  Min message rate is 1 message per 5 seconds 
•  Recommended rate is 1 message per second 
•  Alternatives 1, 2 and 3 has separate talker identifier selection for VTG and 

GLL/GGA/PAT. 

•  Message $XXZDA should only be used with one of the position equipment. 
•  Only alternatives 2 and 3 have Differential-flag for DGPS use. 
•  Only equipment, which has fixed datum (like WGS-84) in their position message 

should be used. Alternatives 6 and 7 check that the used datum is WGS84.
