System overview
LAN port
The TR-8000 transponder contains a LAN port as indicated below. It is possible to output NMEA sentences via this port.
NMEA over Ethernet settings
The display is interfaced over Ethernet by LAN8187, enabling data from 10 to 100Mbit/s. The circuit is galvanically isolated by a transformer and isolated to ground by 2kV capacitors. The interface is compliant with IEEE 802.3-2005 standards. The connector is a circular RJ45 connector, Bulgin PX0833/E on the Transponder and PX0839/PC on the Display Unit. The default IP address of the Transponder is 10.0.0.10 and the default IP address of the Display Unit is 10.0.0.11.
An additional point to point network connection can be set up from the operators panel. Both IP address and port can be set for the connection, and the remote connection must be within the same subnet as the transponder unit. (Default 255.255.255.0). Exactly one sentence is expected in each network packet.
