Ethernet (RJ45)
The LT-3110S Control Unit has an Ethernet LAN (RJ-45) interface, supporting service & maintenance or
connection to the LT-3140S Interface Unit. The Ethernet interface can be used to access the built-in web
server, which is further described in
on page 49. The LT-3110S Control Unit will automatically
request and obtain an IP address when connected to a Local Area Network (LAN) with a DHCP server (e.g. a
router). If connecting the LT-3110S Control Unit directly to a PC, the two will automatically negotiate an
IPv4 Link-Local address. The current IP address can be found in the user interface display (Menu -> System -
> Network: IP Address).

The auxiliary connector is a 10-pin connector (male) mounted on the backside of the LT-3110S Control Unit
as illustrated in Figure 3 on page 7
and marked with ‘AUX’
. The auxiliary connector supports the following
interfaces:
•
RS-422 serial interface
•
2 x Input/output (I/O)
–
not used
The LT-3110S Control Unit is currently supporting NMEA 0183 GNSS Output on RS-422, which can be
configured from the web server, see
on page 49.
NOTE
:
Use only the 91-100768 Auxiliary Cable, 3m delivered by Lars Thrane A/S for connecting to
the auxiliary connector on the backside of the LT-3110S Control Unit. The Auxiliary Cable,
3m is an accessory part and must be acquired separately.
