4. INPUT/OUTPUT SIGNALS

Introduction
The main method for transferring data between a sensor and the ECDIS 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 ECDIS can be interface to analog signals through a B adapter type EC-1020.
For communication with ECDIS this analog adapter use, one serial channel from the LAN
adapter.
Standard interfaces
Gyro compass
• One serial input type of gyro compass (IEC 61162-1 Ed.1 or Ed.2 message $XXHDT...,
min 1 message per second. With radar overlay the recommendation is 5 messages per
second.)
Speed log
• 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).
Positioning equipment
• 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.
