Only 4 NiMh batteries (no fire risk) of the same type AA may be used in the Opto-Box. It is possible
to operate the Opto-Box 100 without internal batteries. However, when supplied via the DC8
socket, the "Low Bat" LED flashes during operation, indicating that no battery can be charged.

The LIN/CAN switch must first be used to select the operating mode.
In CAN mode, at least both CAN pins must be connected to the CAN signal of the DUT. If required,
an internal 120 Ohm terminating resistor (in CAN mode) can be connected via the "LIN / CAN ON
OFF" switch.
In LIN mode, at least the signal line and the ground are connected. If required, an internal 1 kOhm
pull-up resistor (LIN operation) can be connected for the "Master" operating mode via the
"LIN / CAN ON OFF" switch. If the Opto-Box 100 is operated via laboratory plug or D sub-
connector at approx. 12 V, the resistor connects the signal to this voltage. In battery operation, a
12 V voltage is generated internally and the LIN signal is connected to it via the resistor.
To open the housing,
