General Information
The MiniPort-20 Power Relay
provides a 20 amp relay switched 120
VAC outlet, with a terminal strip that allows
remote control via safe, inexpensive,
low voltage Class 2 control wiring. The
MiniPort-15 is identical to the MiniPort-20,
but is rated at 15 amps. Both units include
an internal 12 VDC supply.They are housed
in a rugged all-metal enclosure and come
equipped with a heavy duty, 10 foot AC
cord. The MiniPort-20 and -15 are listed by
Underwriters' Laboratories (UL) for use
MiniPort-20
in the U.S. and Canada. The MiniPort-15Q

If using the delay feature and momen-

Mode. For control from more than one

and 20Q, (see other side), are designed for quad box mounting
and have fewer features.
The MiniPort-20 and MiniPort-15 can be used independently
with an RS-1 System Control Panel, or with any other momentary
or maintained-action SPST switch. MiniPorts can also be used with
the Furman PowerLink or PowerPort for extra capacity.
With the addition of a PS-REL AC Relay, the MiniPort can
also be used to extend the capacity of a Furman PS-8R or
PS-PRO Power Sequencer — or any product with a switched
outlet, such as a receiver/amp controlled with a wireless remote.
When used in this manner, the MiniPort is switched on or off when
the outlet that the PS-REL is plugged into goes on or off.
Momentary vs. Maintained Contact Switching
An on-off switch of either kind may be used to actuate
the MiniPort. Maintained switches, such as most toggle
switches, push-on/push-off button switches, and the Furman
RS-1 locking key switch, stay open until thrown, then stay closed
until thrown again. Momentary switches, usually pushbutton types,
are normally open and stay closed only as long as the button
is pressed.
Maintained switches are most convenient when there is only
one remote switch location; momentary switches allow turn-on or
turn-off from multiple locations.
MiniPorts come factory-configured for maintained op-
eration. They may be easily converted to momentary operation
by moving a jumper on the MiniPort's circuit board. To do this,
first disconnect the unit from AC power. Remove the four screws
that secure the bottom cover. In the middle of the circuit board
(as viewed from the bottom of the unit), there are two
pairs of terminals, one labeled "MAINTAINED" and the other
"MOMENTARY." There is a small black jumper linking the
MAINTAINED terminals. Slide it up and off, and replace it
securely over the MOMENTARY terminals. Reattach the cover.
Maintained Mode
In the simplest configuration, to control a single MiniPort from
a single remote location, connect a maintained-action SPST
switch to the REM and +12V terminals. Power will be available at
the MiniPort-20's AC outlet when the switch is open, and will be
removed when it is closed. If the cable run is greater than 150
feet, we recommend that the REM wire be tied to ground during
on operation rather than leaving it floating, using an SPDT switch
as shown in Figure 1.
Momentary Mode
In Momentary Mode, the MiniPort-20 and MiniPort-15 have
"memory" — they only need a momentary signal on the remote
terminal to change their state from OFF to ON, or ON to OFF.
