1.1 General
This document describes the article NWW-828 Analog Display, Speed Indicator Analogue used for the JLN-900
speed logs.
The indicator range is: 8 knots astern (-0.8V DC) to 30 knots ahead (+3.0V DC).
The Analog Display is based on microprocessor-controlled x-coil system and therefor it needs to be connected to
an external power supply (DC 12-24V).
Note! Pointer position is random until external power supply is connected.

x Connect external power to terminals 1 (-) and 2 (+). Terminals 1 and 2 are located on
the separate two-terminal detachable plug. DC power out for e.g. Display on JLN-
900 Sig. Distributor can be used as source.
Terminals 3 to 8 are found on the other detachable plug, six-terminal plug.
x Terminal 3 (analogue + in) connects to the analogue out on JLN-900 Sig. Distributor
and terminal 4 (GND) to analogue out (0V DC) on JLN-900 Sig.Distributor.
x Terminals 6 (+) and 7 (-) are used for illumination. When dimmable illumination is
desired connect a potentiometer to adjust the voltage on terminal 6.
