Configuration using LT-Service Tool
The LT-Service Tool is a PC program interfacing and communicating with LT-Navigation devices. The LT-
Service Tool is communicating via the NMEA 0183 serial interface. The newest available LT-Service Tool will
be available from the local dealer or distributor, see
www.thrane.eu
(Dealers & Distributors).
File name: LT-Service_vX.XX.exe
NOTE:
The LT-Service Tool is an optional PC program, which can be used together with the LT-1000
NRU. It is possible to install the LT-1000 NRU and use it for navigational purposes, without
configuration by the LT-Service Tool. The LT-Service Tool is intended for installation and
service by trained personnel.
Identify a LT-Navigation device
The LT-Service Tool requires a bi-directional RS-422 balanced or RS-232 unbalanced serial interface in order
to communicate with the LT-Navigation devices. The baud-rate is either: 4.800 or 38.400 baud (configured
on the LT-1000 NRU DIP-switch, see DIP-switch and LEDs on page 21).
NOTE:
It is recommended to use a ‘USB to RS-422 converter’ for easy interfacing in-between the PC
(LT-Service Tool) and the LT-1000 NRU. Interconnection diagrams are illustrated in Connecting
LT-Service Tool on page 25.
Automatic mode:
Step 1:
Double click on the LT-Service_vX.XX.exe file to start the program
Step 2:
The LT-Service Tool will automatically search all COM ports on the PC to identify potential LT-
Navigation devices connected to the PC. Devices found, will be shown in a list, as illustrated in
Figure 43.
Step 3:
If the LT-Service Tool finds more than one LT-Navigation device, then type the number of the
device in the list to be connected with, e.g. “1” and “Return”. If only one device is found, then
the LT-Navigation device will automatically connect.
