INTRODUCTION
The Niles RFG Radio Frequency Gateway is a highly flexible tool that allows system designers
to add a ZigBee®radio transmitter/receiver to Niles MultiZone products or extend the Radio
Frequency Receiver of a Niles HT-MSU Home Theater Main System Unit.
FEATURES AND BENEFITS
MULTI-MODE DIPSWITCHES
Two dipswitches are used to select the operation mode: Master Base, Repeater Base,
Wireless Keypad, and Not Assigned.
NEW EXTERNAL ADJUSTABLE ANTENNA
An external antenna improves reception coverage, range and reliability and is easily
adjustable, regardless of installation restrictions.
INSTALLATION FLEXIBILITY
The low-profile housing, accessible connections, and wall-mount hole wings enable the RFG
to be installed behind components or along a baseboard. The high-impact plastic housing is
heat resistant, so the RFG works well in an attic. Multiple RFGs can be cascade wired over a
single CAT-5 cable run.
RELIABLE ZIGBEE®RF COMMUNICATION
The RFG uses a ZigBee based 2.4 Gigahertz radio frequency that works well in “noisy” RF
environments. The 15-channel* and 15-network ID capability allows multiple RFGs to be used
near each other and in multiple-dwelling units.
RFG EX has 10 channels

QUICK AND EASY SET-UP WITH WIZARD-BASED NILES
CONFIGURATION SOFTWARE
An RFG can be added to any network based Niles MultiZone Receiver or Home Theater Main
System Unit (HT-MSU) using the Niles System Configuration Software. The software is wizard-
based and guides the installer/programmer through basic and advanced system designs.
Configuration is stored in non-volatile memory within the RFG. This safeguards against
accidental loss of programming for the entire life of the product.

1) Power LED - The blue LED indicates that the RFG has power. This LED also indicates
the connection status to the Niles MultiZone Receiver or Home Theater Main System Unit.
2) System Connection - This RJ-45 connection is used when the RFG is connected to
a Niles MultiZone receiver.
3) Keypad Connection - This RJ-45 connection is used when the RFG is connected to
a keypad, a Niles HT-MSU Home Theater Main System Unit, or to continue the CAT-5 cable run
to other RFGs.
4) Power Connection - This barrel type jack is where the power supply connects to the
RFG. A Niles FG01035 Power Supply (optional) is required for certain system configurations.
The ferrite bead is used on the end of the power plug connected to the RFG.
5) Mounting Wings -The RFG can be conveniently mounted to a baseboard, wooden
stud, or directly to the wall. (Mounting screws not included).
6) Set-up Dipswitches - These switches allow the RFG to be configured for one of four
operation modes: Master Base, Repeater Base, Wireless Keypad, and Not Assigned.
7) External Adjustable Antenna - This is the ZigBee Antenna. The RFG should
always be positioned so that the antenna is vertical.
8) Antenna Connection - This screw terminal allows the adjustable antenna to
be attached.
SYSTEM DESIGN CONSIDERATIONS
The Niles RFG Radio Frequency Gateway is a highly flexible tool that allows system designers
to add a ZigBee radio transmitter/receiver to Niles MultiZone products or extend the Radio
Frequency receiver of the Niles HT-MSU Home Theater Main System Unit.
Multiple RFGs are used to create an RF mesh network. RF mesh networks require at least
a transmitter and a receiver, however in large installations repeater bases can be used.

ZIGBEE TERMINOLOGY
To understand how to use the RFG, the system designer needs to understand
ZigBee terminology.
MASTER BASE
The Master Base is the coordinator of the RF mesh network. Its job is to receive
information from the Repeater Bases and End-Points in the system, consolidate that
information, and send it to the main controlled source. The Master Base is like a head
coach in football. His job is to listen to the assistant coaches and players to create and
send the game plan to those that execute it. The Master Base should be located centrally
and as high as possible within the system design. A Master Base is hard-wired to the
main controlled source, the MultiZone receiver, or Home Theater Main System Unit.
END-POINT
The End-Point is where the RF transmitted information starts and stops. For the RFG,
the End-Point is typically a MultiZone system keypad. A system design can have multiple
End-Points (keypads). End-Points can be spread over a large area and communicate
directly to the Master Base, or through a Repeater Base to the Master Base. By its nature
an End-Point will not repeat RF information to other End-Points.
REPEATER BASE
The job of a Repeater Base is to listen for any network RF information, take that
information and re-transmit it so that other bases can pick it up if they are too far away
for direct communication.

ZIGBEE RF NETWORK
When designing an RF network it is important to know that at least one Master Base
and one End-Point are needed. Repeater bases are used to expand the coverage area
of the RF network. Multiple hops can be used in an RF network design, however great
care should be used to not exceed more than four hops. To count the hops, start from an
end-point, and then add one for each Repeater Base used between the End-Point and the
Master Base. See Figure 1 for basic RF network system design.

RFG USAGE WITH NILES NETWORK-BASED MULTIZONE RECEIVERS
The RFG can be used with Niles Network-based MultiZone receivers allowing the installer to
create “wireless keypads.” Typically, control keypads are connected to the MultiZone receiver
via a CAT-5 cable. In installations that do not allow a run of CAT-5 cable (such as a retrofit
or a detached area from the main equipment area), use the RFG to overcome the hard-wired
limitation. The dipswitches pre-configure each RFG to the application for which it is being
used. See Setting the Dipswitches section.
RFG USAGE WITH A NILES iC2TM HOME THEATER
AUTOMATION & CONTROL SYSTEM
The Niles iC2 uses RF communication between the iC2 Tabletop Controller and the Home
Theater Main System Unit (HT-MSU). In other words, there is a Master Base built inside of the
HT-MSU and the iC2 remote is an End-Point. The HT-MSU is typically located behind the home
theater gear in an equipment rack. That is usually the worst place for the Master Base to be
located due to the metal and noise (interference) created by the home theater sources. One RFG
can be used to replace and extend the built-in Master Base to an area where there will be little
or no interference. The RFG is hard-wired to the HT-MSU using CAT-5 cable terminated with
RJ-45 plugs. Please see the Installation Section for proper termination wiring.
SETTING THE DIPSWITCHES
The two dipswitches on the RFG allow for it to be pre-configured to one of the four modes:
1) MASTER BASE
2) REPEATER BASE
3) WIRELESS KEYPAD (END-POINT)
4) NOT ASSIGNED

SYSTEM DESIGN WIRING FOR RFG
The RFG has two RJ-45 connections for wiring into the system. The connection used depends
on the mode and overall system design.
A MASTER RFG CONNECTED TO A NILES NETWORK-BASED MULTIZONE RECEIVER:
An RFG with dipswitches set for Master Base mode must be connected directly to the
MultiZone receiver using CAT-5 cable as detailed in Figure 2. No power supply is needed.
A master RFG can be wired with repeater RFGs by wiring the CAT-5 cable from the MultiZone
Receiver’s Communications port to the System connection of the first RFG, and then from the first
RFG’s Keypad connection port to the System connection of the next RFG. Two RFGs can be daisy
chained to the receiver without an additional power supply. If three RFGs are daisy chained, a Niles
power supply (FG01035) must be connected to an RFG in the chain. If more RFGs are required, note
that the Niles power supply can supply power to up to three adjacent RFGs in the chain.
