what is the second DEU type A

孱弱的翅膀 · 发表于 2012-12-30 14:53:31

In each area of the aircraft (left, right and center), the top lines are connected to every second DEU type A.
Thus a failure in one top line will only cause every second DEU type A to become unserviceable.
Every connection-box has coding switches which give each DEU type A its own address. The last connection box that is connected to a top line also has a termination resistor for impedance matching.

these words come from AMM23-73-00pb001 Architecture .

呵呵，客舱左右各有两根TOP line
每根线上DEU的连接方式是隔一个连一个every second DEU type A。
以保证一根线断了，还有一半的DEU可用。

if you understand the word "everyone"
then the word "every second"means: every one+one

A32里边见过，客舱里编码译码器有DEU A和DEU B两种，具体干啥的，还真没好好学过

As your says,there are 4 top lines and 2 middle lines.Each of them is from the cabin head to the tail.
So I made a mistake.I thought there were 2 lines in each side,there began at head and tail then conneted in the middle cabin.
