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 into which the PS-REL is plugged 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 switched, then stay closed until switched 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 operation. They may be easily converted to momentary operation by moving a jumper on the MiniPorts 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.

For control from more than one location, use Momentary Mode and parallel switch connections.

TO OTHER UNITS

If using the delay feature and momentary switches, first unit must be in Momentary Mode, all others in Maintained Mode. For control from more than one location, parallel switch connections to Unit 1.

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 MP15/20s 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 operation rather than leaving it floating, using an SPDT switch as shown in Figure 1.

General Information

The MP-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 MP-15 is identical to the MP-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 MP-20 and -15 are listed by NRTL for use in the U.S. and Canada. The MP-15Q and 20Q are designed for quad box mounting and have fewer features. The MP-20 and MP-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 ASD-120

Momentary Mode

In Momentary Mode, the MP-20 and MP-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. When first plugged in (or after power is lost
and reapplied for any reason) the memory state is OFF, meaning that no power will be available at the outlet. It will stay OFF until turned ON by a momentary connection of the REM terminal to +12V. It will then stay ON until turned OFF by a second momentary connection. The ON or OFF state begins on the rising edge of the signal. IMPORTANT NOTE REGARDING MOMENTARY MODE: If multiple MiniPorts are being controlled in Momentary Mode, power loss to any one of the units will likely cause its memory to be different than that of the other units. Not only will this be irritating, it can also be dangerous, as it may be ON when the others are OFF. To correct this potential problem (as exists in any simple momentary switch product), our thoughtful engineers devised a simple method of holding the switch down (REM to +12) for at least four seconds. This resets all units to the OFF condition, and avoids having to disconnect AC power from all units.

If it is HIGH (+12V relative to the GND terminal), the unit is ON; if LOW, the unit is OFF. Simply connect the indicator LED between STATUS and GND (do not use a series resistor). If multiple units are used, a separate LED must be used to indicate the status of each. Do not connect the STATUS terminals of multiple units together.
MP-20Q/15Q Quad Box Power Relays
The 20-amp MP-20Q and the MP-15Q (15 amps) provide a pair of remotely-activated, relay-controlled outlets, set up for mounting in any standard electrical quad box, either directly or with a mud ring attached. Due to the space limitations of a quad box, the MiniPort Q models have a smaller feature set than the MP-15 and MP-20. MiniPort-Qs have no internal power supply; a maintained 8-15 VDC supply capable of providing 10 mA is required to turn on the outlets. This can be supplied by a Furman PowerLink, ASD-120. (See diagram on the back for more details)

Linking Multiple Units

Multiple MiniPorts may be connected together so that all are controlled by a single switch closure. All the units must be set to the same mode depending on the type of switch or switches to be used (use momentary mode and momentary switches if more than one switch is required.) All the units must be paralleled by tying together all the +12V terminals, all the REM terminals, and all the GND terminals (see Figure 1). Multiple MiniPorts may be linked so that they all turn on simultaneously, as discussed above, or in a delayed sequence. In a delayed sequence, only the turn-ons are delayed (all turn-offs occur simultaneously.) This feature is particularly useful in staggering the turn-on of large power amps to avoid large inrush currents that might trip the house circuit breakers. The delay interval is approximately two to three seconds (the first unit turns on with the switch closure, the second in the chain about 3 seconds later, the third unit 3 seconds after the second, etc.) The choice of delayed or simultaneous linking is available regardless of whether maintained or momentary switching is used. However, if delayed linking is used with momentary switching, only the first MiniPort should be set to momentary mode, and all momentary switches should be connected in parallel between the first units +12V and REM terminals. The second and subsequent MiniPorts must be left in maintained mode. See Figure 2.

Accessories: RS-1, RS-2

The Furman RS-1 Remote System Control Panel is an attractively finished key switch designed for use in singlegang wall mount boxes. From one location it can control most Furman power products with remote capability. The RS-2 Remote System Control Panel is identical to the RS-1 in most respects, but with a momentary function rather than maintained. The RS-2 is ideal for installations requiring multiple remote switches.

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.
Both the MINIPORT-15 and the MINIPORT-20 come equipped with two knockout holes for permanent installation with 1/2" conduit one on the top surface, the other on the bottom. Use of the bottom knockout hole requires removing the AC cord. According to the National Electrical Code, 1/2" conduit can accommodate up to five 20 amp circuits using ten THWN 12 gauge stranded wires; however, local codes should be checked for exact requirements. MINIPORTs are housed in rugged steel enclosures and come equipped with a heavy duty, 10 foot AC cord. The MINIPORT-15 is fused; the MINIPORT-20 is equipped with a precision magnetic circuit breaker. The MINIPORT-20 and MINIPORT-15 are UL and CUL (Canadian) listed.

MiniPort-20

The Furman models RS-1 and RS-2 are maintained and momentary key switch panels (respectively) that fit in a single gang electrical box. For control from more than one location, the RS-2 momentary switch would be appropriate. See overleaf for more information.
Both models include an internal 12 VDC supply, and can be controlled from a remote location with maintained or momentary contact switches.
Also available is the MINIPORT-15 (not shown), which is functionally identical except for its 15 amp rating.
Note: Because of its UL listed 20 amp rating, the MINIPORT-20 uses a 20 amp AC plug with perpendicular (not parallel) blades. If in doubt regarding your installation, please consult an electrician or call the factory. The MINIPORT-20 is an upgrade of an earlier Furman MINIPORT. The primary differences are the ability to use momentary switches, the delayed turn-on option, and the additional knockout holes.
Dimensions: 5.5" (H) x 3.75" (W) x 2" (D). With mounting bracket, width is 5.25".
MINIPORT-15Q, MINIPORT-20Q
Multiple MINIPORTs may be connected together so that all are controlled by a single switch closure, and may be linked so that all turn on simultaneously or one by one, in a delayed sequence. If delayed, the delay interval between the turn-on of one MINIPORT and the next is approximately 3 seconds. (Delayed turn-on is useful in avoiding large inrush currents that can trip house circuit breakers, that would otherwise occur if all amps were turned on simultaneously.) Turn-off always occurs simultaneously, however. A Furman PowerLink (see overleaf) can also be used to control MINIPORT(s). In this use, the MINIPORT(s) are connected to terminals on the PowerLink, which provide the necessary control functions. MINIPORTs are similarly compatible with the Furman PowerPort and ASD-120 Sequenced Power Distro.
The MINIPORT-20Q (20 amp) and the MINIPORT-15Q (15 amp), provide a pair of remotely-activated, relay-controlled outlets, set up for mounting in any standard electrical Quad Box, either directly or with a mud ring attached. Due to the space limitations of a quad box, the Q models have a smaller feature set than the MINIPORT-15 and MINIPORT-20. There is no internal power supply; a maintained 10-30VDC supply capable of supplying 10 mA is required to turn on the outlets. This can be supplied by a Furman PowerLink, or ASD-120. UL, c-UL pending.
With the addition of a PS-REL AC Relay (see overleaf) to provide control, a MINIPORT can be used to extend the capacity of any other Furman power product or, for that

POWERLINK

REMOTE SEQUENCER
The PowerLink is a compact, low-cost rackmount remote sequencer that provides timing for up to six power control devices, turning them on and off in a preset sequence. The delay interval between steps is user-adjustable via an internal trimpot.
models include a locking key switch and a System On indicator LED. The RS-2 includes a momentary Start ON/OFF Sequence pushbutton, while the RS-1 is a maintained contact version. The rear of the panels have a circuit board with a full size barrier strip for field wiring connections. The RS-1 and RS-2 can be used to control the Furman ASD-120 Sequenced Power Distro, the PowerLink, PowerPort Remote AC Controller, the MiniPort Power Relay series, or the PS-8R or PS-PRO Power Sequencers, as well as other equipment that needs a switch contact at a remote location. Dimensions: 4.75 (H) x 2.75 (W) x 1.5" (D).

PowerLink

A PowerLink can work with a group of relay-controlled outlets such as MINIPORTs, to create a very flexible power control system that can expand to handle as many circuits as needed. An on or off sequence can be initiated from the PowerLink, using the built-in high-security locking key switch, or, if the key switch is set to enable Remote operation, by one or more momentary or maintained-action switches in distant locations. The outputs of the PowerLink are low power relay contacts, accessible through rear-panel screw terminal strips. All input and output commons are electrically isolated to avoid the creation of ground loops. Normally open and normally closed relay operation is selectable by internal jumpers. ETL, C-ETL listed.

AC RELAY ACCESSORY

PS-REL
The PS-REL AC Relay senses the presence of 120 VAC and closes a SPDT relay. The relay contacts are available on a barrier strip. It may be used with any product that needs a contact closure in response to AC voltage. A common application for the PS-REL is to extend the capacity of the switched outlet found on many home theater receiver/amps. In this way, a wireless remote can turn on the receiver, which in turn powers its switched outlet, which triggers the PS-REL, which then activates a Furman power sequencer, PS-REL MiniPort, or PowerPort system capable of switching many large power amps or other powerhungry equipment in multiple locations, attached to multiple circuits.

RS-1, RS-2

REMOTE SYSTEM CONTROL PANELS
The RS-1 and RS-2 Remote System Control Panels provide a simple way to control AC equipment from one or more locations, using only inexpensive lowvoltage wiring. The panels can be easily installed in a single gang switchbox with a minimum depth of 1.5". Features common to both
