The maximum total length of all CANBus cabling associated with a specific Element should never exceed 100 feet (30 m). This includes the length of the power supply cable that connects the Element surface to the PowerStation or Studio Engine, since this is also a part of the CANBus. Best practices dictate keeping the CAN bus length to a minimum: a practical maximum is about 40 ft. Proper termination is also required.
The Engine should be between 40-50 degrees Celsius, with maximum temperature spikes into the 50 degree range. Any piece of gear that is running consistently in the 60 degree Celsius range is not being properly ventilated.
Press and hold the control knob for 6 seconds during boot up of the device.
