GENERATOR USER PORT (15-PIN)
The 15-pin Generator User port on the HFV generator provides analog and digital
signals for controlling and monitoring the unit. This section describes the User port
connector, the minimal User port connections required to operate the unit, User port
cabling requirements, and detailed information about the User port signals.
The Generator User port is a 15-pin, shielded, female, subminiature-D connector
(see Figure 4-1).

Satisfying DeviceNet™ Minimum Requirements
Regardless of whether you are controlling and monitoring the generator through the
Generator User port or through another port, the INTERLOCK LOOP signal (pins 11
and 12) of the Generator User port must be satisfied for the HFV generator to
operate. In other words, even if you are controlling the HFV generator through the
DeviceNet interface, the interlock signal must be satisfied. (For a wiring diagram, see
Figure 4-7 on page
If you are not controlling or monitoring the unit through the Generator User port, you
can use a dummy or cheater plug to satisfy these two signals and thereby ignore the
Generator User port. To make such a plug, solder a jumper on a mating conductor
between pins 11 and 12 to satisfy the INTERLOCK LOOP signal. To determine the
physical location of these pin numbers on the Generator User port, see
If desired, you can add an emergency off switch in series with the RF PWR ENABLE
signal (pin 4) or tie your system interlocks in series with the generator INTERLOCK
LOOP signal (pins 11 and 12) by following the connections for those pins described in
