1 General
The Distribution Unit 138--118 consists of an aluminium casting in which 2 printed circuit
board are integrated.
-- I / O -- P C B
-- Interface PCB.
At the bottom of the casting there are 40 cable inlets for connecting repeaters, gyros and
other heading receivers and sensors.
The task of this distribution Unit is:
-- Distribution of heading information to all connected heading receivers.
-- System monitoring by alarm--and status messages.
-- Gateway between DV--Bus and CAN--Bus.
-- Power supply of all connected heading receivers and heading sources (sensors).
-- Storing of values for variation and deviation for the magnetic compass.
There are no operating procedures during the normal operation of the distribution unit.
Only the setting to work--procedure needs some settings performed by DIP--Switches at
the CAN Network Modul Interface PCB.
Options
are:
“Additional output box” for additional output signals.
“AC/DC--Converter” to generate the supply voltage for the distribution unit.
