7. Application
An Opto-Box 100 converts electrical CAN or LIN signals into optical signals. The use of two Opto-
Box 100 provides a simple possibility to cut an already existing cable connection and to replace a
section of the cable - without further configuration effort - by an optical fiber connection.
It is also possible to combine an Opto-Box 100 with a LIN 100 or CAN 100 sensor. The respective
sensor should be used directly on the DUT's circuit board. In this way, the CAN or LIN cable can
be completely replaced by a optic fiber cable for measurements during development within the test
hall/screening cabin, thus achieving a very high interference immunity of the signal connection. At
the same time, the interference decoupling from the signal cable is omitted.
Preferably, one Opto-Box 100 is used directly on the higher-level computer and communicates to a
second Opto-Box 100 or a LIN or CAN sensor close to the DUT - e.g. inside a measuring cabin.

8. Design of Opto-Box 100
8.1. Mechanical Design
All connection options and switches are shown in Figure 1.
Figure 1: Operating elements of the Opto-Box 100
8.2. GND Connection
The Opto-Box has a solid metal plate on the bottom side, which is galvanically connected several
times to the internal GND.
If the Opto-Box 100 is used in the context of interference immunity tests, it should be operated
isolated from the rest of the set-up in order to achieve the highest possible interference immunity of
the signal transmission. Many standards require this set-up anyway. For this purpose, the Opto-
Box must be placed isolated - if possible with a distance of a few centimeters - above the
frequently conductive substrate of the measurement set-up.
For measurements during development, however, it may be useful to connect the DUT and the
Opto-Box to a conductive substrate in order to reduce RF coupling in or out. In this case, it is
sufficient to simply place the Opto-Box on the conductive substrate (Figure 2).
