MARIS ECDIS900 Installation Manual
OTHER NETWORK FUNCTION (ONF)
Sensor Monitor (SM) is used as ONF. It sends 61162-1 sentences to the network using
broadcast messages and internal format. SM doesn’t use multicast, IPs and ports from the
standard. It uses ports 8001 and 8005, and broadcast IPs 192.168.3.255 (255.255.255.0).
NETWORK PROTOCOL
The ECDIS900 uses network IP Version 4 protocol.
IP ADDRESS ASSIGNMENT
• MONITORING ECDIS: 192.168.1.150 (LAN PORT 1 for ECDIS interconnection), and
192.168.123.150 (LAN PORT 2 for Internet access).
• PLANNING ECDIS: 192.168.1.151 (LAN PORT 1 for ECDIS interconnection), and
192.168.123.151 (LAN PORT 2 for Internet access).
• SIS4000 Mk2 NMEA Serial to Ethernet converter 192.168.4.200.
Note:
The ECDIS900 does not reserve any sub-nets.
In an ECDIS900 network, each datagram is transmitted and received within the multicast
address range 239.192.0.1 to 239.192.0.64.
NETWORK INTERFACE
The Ethernet switch, Moxa EDS-405A Series, is used in an ECDIS900 installation. It provides
IGMP Snooping, QoS, IEEE 802.1Q VLAN, port-based VLAN support, and supports standards
IEEE 802.3u for 100BaseT(X), 100BaseFX and IEEE 802.3x for flow control. For more information,
refer to the EDS-405A Managed switch installation guide.
The Ethernet cables used in an ECDIS900 system are CAT5 STP four shielded twisted pairs, or
ISO/IEC 11801 (Class D).
DATAGRAMS
The maximum datagram input rates are:
a) 1000 for the maximum number of datagrams per second received, intended for,
and processed by the equipment.
b) 500 for the maximum number of datagrams per second received by, but not
intended for the equipment.
c) 300 for the maximum number of datagrams per second received by, but not
intended for the equipment, at 50 % of the maximum load for item a) in this list.
MAXIMUM OUTGOING RATE
The ECDIS900 uses 100MB LAN. Significant network traffic is split between sensor data traffic,
radar overlay when it exists, and communication with VDR.
Sensor traffic is limited to a maximum of 3000 datagrams, which is about 1 MB per second.
Traffic to send an image to the VDR is 100 KB once per 15 seconds.
Note:
For the ECDIS900, it is recommended to not set the UDP packet send limit lower than
the default setting (150 000 datagrams per second).
