Dimming setup
e Dimming levels can be set up on this screen. e user can select dimming and color choices for the 4
preset levels that can be sent remotely (using DDC NMEA command). When the user uses the on screen
dimming, the color scheme will change when the dimming level passes the set % value.
Network setup
e system uses TCP/IP for upgrade, and as default is set to 172.16.1.105. Subnet mask is set to
255.255.255.0. e system allows use of private IP addresses including the recommended IP addresses
according to the standard. If a non recommended IP address is entered, a pop up warning will show, and the
colour of the IP address on screen will be orange. Only static addresses can be used.
e system uses the IEC61162-450 (2018) LWE communication standard. is uses a multicast methodol-
ogy, where NMEA style messages are sent on one of a number of multicast addresses/ports, as specied
in the standard. ese are called transmission groups, and the natural group for the system is navigation
‘NAVD’. Messages are sent using the datagram type UdPbC & RaUdP is used for echogram data. On startup
a Identication message (SRP) is sent on the NETA group, dedicated for this as dened in the standard. is
information will give the System Function Identier (SFI), MAC address and the IP address.
is standard requires a unique identier for this equipment this is called the System Function Identier
(SFI). is is set by default to SD0105, but can and should be changed if more than one device on the net-
work. e SFI is made up of 2 letters ‘SD’ as designated for an echosounder, and 4 digits from 0001 to 9999.
is is used to allow the equipment to identify itself to other equipment, and to lter which messages are
aimed for this device.
SFI, and IP address can also be adjusted using the SKIPPER service soware. UDP messages can also be
viewed from this soware.
e messages sent can use the following tag blocks as dened in the standard: s:,d:,g:,x:,z:,n:
