1 Introduction

The digital LAMBRECHT meteo indicators METEO-LCD 

(14742) are multipurpose indicators which are designed to 

display the various meteorological and nautical parameters. 

There are special versions for applications on civil ships (NAV) 

and for industrial (IND) purposes. The versions -IND and  

-NAV are also available as versions -IND/ W and -NAV/ W for 

water resistant panel mounting (front plate design of the LCD 

in the style of protecting class IP 66).

In order to enable a safe reading under different lightning 

conditions contrast and brightness can be aligned over a 

wide range.
Just like many other electronic devices, which are in use for 

such purposes on ships the standardised data input of the item 

is carried out in accordance with the NMEA 0183 standard 

version 2.30. Assumed that all digital input information are 

available from a talker, the below mentioned modes of opera-

tion can be selected with a simple operating menu.
If the indicator was purchased as a component of a complex 

meteorological measuring system, further operating manuals 

of other devices as well as general wiring diagrams of the 

entire system have to be considered.
Before starting installation and connection work on the indi-

cator, we recommend checking the delivery for damage and 

completeness.

Functional description

For the display of information an illuminated transmissive 

LC-Display with 160 x 128 dots is in use. In order to adapt it 

to the ambient conditions contrast and brightness can be set 

by the user.
For the signal input a serial RS 422 interface is provided. 

All incoming data are expected as digital message strings 

according to the NMEA 0183 standard which nowadays is 

world-wide in use.
Once switched on the power supply the display will show 

“System init... Please wait...” for approx. 15 seconds and after-

wards an opening mask containing the firmware version for a 

short time and than it will move to the final mode of operation 

as it has been in use before.
All required data have to be transferred to the indicator 

as standardised serial data strings in a message format 

according to the NMEA 0183 format e.g. generated by a 

LAMBRECHT meteo data logger or a similar device. More 

information can be obtained from the chapters at the end of 

this document.
The 24 VDC supply voltage and the serial interface RS 422/485 

are galvanically isolated.
