User Port Interface Cabling Requirements

Connect the HFV generator's User port to the system controller with a shielded, 15-
wire I/O cable. Shielded twisted-pair wiring may be used but is not mandatory.
Minimize signal losses by keeping the cable as short as possible. The maximum
recommended cable length between the HFV generator and the controller is 10 meters
(33 feet). Minimize interference from adjacent electrical equipment by terminating the
EMI shield in the cable to the metal shells of the cable's connectors. Additionally, you
must tie the chassis of the HFV generator to a local earth ground through an
adequately sized copper grounding strap.
Note: Grounding the User port at the HFV generator reduces noise interference. To
avoid ground loop problems, you should typically ground only one end of the
User port cable.
