Appendix C – Enabling the CAN bus Write capability
Connecting the C660 to a CAN network can be dangerous. If the C660 is not configured with the
correct network parameters, it can lead to network corruption and may interfere with other
connected equipment on the bus. Especially in vehicles great precautions must be observed to
prevent interruption of the communication.
By default reading from the CAN bus is enabled and writing to the CAN bus is disabled.
Installing jumper JP901, and thereby enabling the CAN-bus Write capability of the unit, is done
on the sole responsibility of the user. M2M Control can not be held responsible for any problems,
or damage due to the decision to enable the CAN-bus Write capability.
The following steps must be taken to enable the CAN bus Write capability of the unit:
1.
Disassemble the unit as described in the Appendix A
2.
The jumper is located near the back panel as shown in the picture above.
