3. Troubleshooting
3.1 Common Sources of Problems
 Please make sure UTP cable is terminated properly (TIA/EIA-568 A or B).
 Do not plug this unit to LAN devices (this can damage the unit and void
warranty)
 For noisy environments (or cases where the twisted pair cable is bundled with
mass of other data, telecom, and/or power cables), shielded cable (STP) is
recommended.
 If STP is used, then cable’s shield drain wire
must have electrical contact on the RJ45
shield at BOTH ENDS. If there are
intermediate wall-plates that the cable passes
through the shield drain must be carried
through and not left open or floating.
 Make sure you are using the
Sender/Receiver pairs that came together in
the box, since newer versions of the product may not be backward compatible
with earlier ones. The current version is Rev B. The white box indicates Rev B,
and all Rev B serial numbers (on the bottom of the product) end with letter B.
3.2 Contacting Hall Research
If you determine that your unit is malfunctioning, do not attempt to repair the unit. The
unit contains no user serviceable equipment. Opening the unit will void the warranty.
Contact the Hall Research Technical Support department at 714-641-6607 to obtain a
RMA (Return Authorization) number.
Before you do, make a record of the history of the problem. We will be able to provide
more efficient and accurate assistance if you have a complete description.
3.3 Shipping and Packaging
If you need to transport or ship your unit, pack it carefully (original container
recommended) and contact Hall Research for a Return Authorization (RMA) number.
