7.2.1 IEC61162-450 Image output
The ECDIS supports transmitting a screenshot of the display to a VDR every 15 seconds, in
accordance with IEC61996-1 Ed.2 Appendix E, and the chart information in accordance with
IEC61996-1 Ed.2 Appendix G.
When using the image output it is vital that is configured correctly so as not to disturb the existing
ship network usage.
The settings are:
1. Output interface: The external interface must be enabled for the image output to work.
2. Source SFI: The System Function ID of the ECDIS. This SFI must be unique on the entire
network.
3. Location: The location of the ECDIS. E.g. Starboard ECDIS, Conning ECDIS. The location
must be unique within the ECDIS-class of equipment.
4. Transmission group: IEC61162-450 defined binary re-transmittable transmission group to
be used for transmission.
5. Destination SFI: The system function ID of the VDR (or similar equipment) to receive the
images.
6. Transmission time offset: Offset by which the image should be transmitted. This is to
offload the network. IEC61996-1 Ed.2 defines the following:
1. ECDIS node 1 transmit at time offset 8 seconds
2. ECDIS node 2 transmit at time offset 12 seconds
3. ECDIS node 3 transmit at time offset 2 seconds
4. ECDIS node 4 transmit at time offset 6 seconds
7. Source port: The transmitting port of the ECDIS.
Two types of data are transmitted as different intervals:
3. Screenshots (images) every 15 seconds
4. Chart information whenever new charts (cells) are displayed, or at least every 10 minutes.
