Solving problems with static electricity

The operation of devices incorporating the IEEE-1394 bus can be disrupted by a static discharge if the device and host are not properly grounded. We have found some IEEE-1394 PC host adapters where the cable shield is not properly grounded. In this situation a static discharge can actually cause the PC to reset.

To rectify these problems we recommend running a grounding wire directly from the case or mounting bracket of the IEEE-1394 device to the PC motherboard case. This provides a path for the static discharge and should result in reliable operation.
