10.3. Electrical Connection
The CAN 100 is supplied with GND and +5 V supply voltage from the electronics module. If the
supply voltage rises above approx. 7 V, the CAN 100 switches off to avoid overheating. Both CAN
pins are connected to the CAN signal of the electronics. If required, an internal 120 Ohm terminat-
ing resistor can be connected via the switch on the CAN 100.
The edge steepness of the signals output by the CAN 100 can be changed with a screwdriver.
Depending on the transmission rate, a minimum edge steepness is required; at a transmission rate
of 1 Mbit/s, the setting control must be set to "fast" (delivery state).
The LIN 100 is supplied with GND and supply voltage from the electronics module, the LIN pin is
connected to the LIN signal of the electronics. Via the switch at the LIN 100 an internal 1 kOhm
pull-up resistor can be connected if required (for operation as master).
With a screwdriver the edge steepness of the signals output by the LIN 100 can be changed.
Depending on the transmission rate, a minimum edge steepness is required, at 20 kHz
transmission rate the setting control must be set to "fast" (delivery state).
Note: To measure error-free under RF irradiation, burst or ESD, the CAN 100 must be
connected to the DUT for a very short time.
Probe tips of the usual type are too large. For a correspondingly small-scale setup, it is recom-
mended to solder the CAN 100 directly into the module via an adapter socket (included in the
scope of delivery). For this purpose, the socket is glued onto the PCB or an IC of the DUT (with
superglue or double-sided adhesive tape) and briefly connected to the DUT with CuL wire accord-
ing to the pin assignment (Fig. 12).

Hint:
The closer the CAN 100 / LIN 100 is
arranged with its housing to the GND
system of the DUT and the shorter
the GND connection to the module,
the greater the interference immunity
of the set-up.
