Note!
For connecting BUS IN and BUS OUT, we recommend our ready-made Interbus cables (see
chapter 11.4.5 "Accessory ready-made cables for Interbus").
Attention!
The laser measurement system can be used to branch out the Interbus network. The exten
-
ded network is connected via BUS OUT.
The integrated SUPI (Serial Universal Peripheral Interface) automatically detects whether
other participants are connected to BUS OUT. BUS OUT does not require termination.

Interbus shield and grounding concept
The cable shielding must be concentric and cover the entire cable up to the M12 connector
(thread).
Inside the AMS 384
i
, the M12 thread for BUS IN is connected to functional earth (FE) via an
RC element (1M
Ω
|| 15nF). The M12 thread for BUS OUT is conductively connected to the
housing and therefore directly to functional earth (FE).
