Please observe the following guidelines for set-up:
• Power supply lines should only be passed in pairs as close together as possible.
• Sensitive signal lines should be shielded to achieve highest possible damping,
and under this shielding they should be still passed twisted.
• Metal plug connections should be used for shielded lines.
• Cable bundles should be distributed in accordance with their purpose (e.g. HF,
LG, and power supply); the groups thus formed should not be routed in parallel
to the extent possible, and they should be routed with clearance.
The OPUS B4 relies on a connection to an ECU that controls the functions and features
of the target vehicle/machine.

start scripts on the unit (start scripts for Projektor Tool and CODESYS application
already installed by delivery).

newly downloaded application will replace the old one automatically.
Penetrating humidity by unused and unprotected plugs may
cause damage of the unit. Please protect unused plugs with the
special blind inserts that have been supplied with the units.
The ECU must be the component in charge of all safety related
functions.
Wrong connection may cause damage of the unit.
