NOTICE
Risk of damage to unit
The power supply MUST be plugged in and switched on when cables
are attached and plugged in. For example, if no power cable is
connected to the DX71, the module has no ground connection to the unit
and there is no potential equalization. If the CAN cable is plugged in, the
CAN transceiver (IC on the DX71) can be destroyed by the voltage
difference. In other words, when the unit is switched on, CAN cables
may only be plugged in on modules that are connected to the power
source and ground.
For troubleshooting, you can disconnect the CAN bus cable and/or plug
it back in and observe the (unit's) behavior.
