Figure 5: Power supply PCAN-GPRS Link
The PCAN-GPRS Link goes to sleep mode, if no CAN data is
transmitted/received, the microcontroller is inactive, and clamp 15 is
low. Activation of the PCAN-GPRS Link is in this case only possible
via CAN or clamp 15.

Termination
A High-speed CAN bus (ISO 11898-2) must be terminated on both
ends with 120 Ohms. Otherwise, there are interfering signal
reflections and the transceivers of the connected CAN nodes (CAN
interface, control device) will not work.
The PCAN-GPRS Link does not have an internal termination. Use
the adapter on a terminated CAN bus.
