Terminal Barrier Strips
SMART SEQUENCING– 4 Pin Phoenix-Type
The SmartSequencing Barrier Strip is used to connect
and daisy-chain other SmartSequencing units together.
SmartSequencing requires that a pair of wires be
connected between the Primary OUT terminals of one
sequencer to the Secondary IN terminals of a second
sequencer. The recommended wire is 22AWG but
SmartSequencing is extremely tolerant of wire gauge.
Remote Port – 5 Pin Phoenix-Type
The Remote Port Barrier strip is provided to allow Furman Legacy devices
to be interoperable with the Miniport. One or more remote location
switches can be connected to the Miniport. The switch or switches used
may be either a momentary or maintained-contact type. In the most basic
configuration, only two wires and an SPST switch are needed to initiate
a remote ON or OFF sequence. If a four-conductor cable is used, an LED
may be installed between the STAT and GND pins to indicate when the
power outlets are on.
Setup and Troubleshooting
As discussed at the introduction, in order to prevent expensive repairs to
speaker enclosures, a power sequencer or multiple power sequencers
are employed to coordinate the activation of power within an A/V system.
The amplifiers receive AC power last when a system is turned on and
amplifiers have the AC power cut before the signal processing is turned
off. There are many applications besides those pro audio applications
discussed here and SmartSequencing opens up many possibilities. We
cover the basics within our documentation, yet this does not mean that
other applications cannot garner the benefits of SmartSequencing.
Security and IT professionals can also benefit from remote power
management and power sequencing. Please feel free to consult a
Furman professional to answer any questions or to address the needs
for any particular installation.
Single Unit Set Up
Basic installation of the Miniport is ready right out of the box. The default
DIP Switch settings should be appropriate for a single stand-alone instal-
lation.
Multiple Unit Set Up
If you plan to use the Miniport as a Secondary device within a chain of
sequencers, the Miniport will need to be changed from Primary to Sec-
ondary status. This is done by changing the setting of DIP switch #8 from
ON to OFF and then cycling power.
If you are using several Miniports to control an AV system it is recom-
mended that you connect the signal processing equipment to the Mini-
ports near the beginning of the chain, and the Amplifiers to the sequenc-
ers nearest the end of the chain. This will ensure that the power to the
signal processing equipment will be active and have had the opportunity
to stabilize before power to the amplifiers is activated.
Breaker Overload
The overall current capacity is 15Amps for the CN-15MP and 20Amps
for the CN-20MP. This refers to the combined steady-state current drawn
by all devices plugged into the power outlets. If the combined current
level exceeds the current capacity at any time, the circuit breaker will trip,
cutting off power to the connected equipment. If this occurs, the operator
must reduce the load by unplugging one or more devices.
Although 15 Amps is an absolute limit, the CN-15MP will allow the
operator to come as close as possible to using the full 15 Amps. Power
sequencing greatly reduces the risk of tripping the breaker because
power sequencing offsets large but temporary inrush currents by activat-
ing equipment in stages, rather than simultaneously. This allows each
stage to settle to its steady-state current draw before the next stage
is powered. If for any reason, reasonable efforts are made to resolve
breaker trips and trips continue, please to do not hesitate to contact
Furman technical support.

FORCE OFF (2) – 2 Pin Phoenix-Type
The FORCE OFF input provides terminals for initiating an immediate
shutdown of all SmartLink devices in a SmartLink chain. Fire alarms and
other safety devices can be connected to the FORCE OFF input. When
activated, the system will begin an immediate, but orderly shutdown
starting with the last sequencer in the chain first.
