INTRODUCTION
The model 130 series RF transceivers are designed to provide a
wireless, meshnetworkRS485/422 interfaceover an unlicensed
900MHz RF data channel. The application discussed in this
manual utilizes an NI-700 NetLinx Integrated Controller made by
AMX and the Aprilaire model 8870 Communicating Thermostat.
The Aprilaire 8870 thermostatsupports a hardwiredRS485/422
serial communication channel such as that provided byan NI-700
serial port. Through the NI-700, information can be receivedfrom
and commands can be sent to individually addressed thermostats.
As many as 64 thermostats can be connected on a single network.
The model 130 series RF transceiver provides a transparent
wirelesscommunication channel between an NI-700 and its
associated thermostats.
There are two physical configurations of the model 130 as well as
two operating configurations. Figure 1 above shows a model 130
Remote Communication Node or RCN, which is located with an 8870
thermostat. This configuration provides two power wires, four
RS485/422 serial communication wires and a 12” long coaxial
antenna. It should be powered by the same 24VAC as the
thermostat. (Black ‘C’wire MUST connect to the thermostat ‘C’
wire-Red ‘R’wire MUST connect to thermostat ‘R’wire.) Figure 2
depicts a model 130SMA Master Transceiver. In this physical
configuration, the four serial communication wires are replaced by
a 9-pin female serial connector. The antenna is replaced by the
SMA style threaded connector which mates to a remote antenna
connector.Operating configuration setup is covered later in this
manual.

OPERATING CONFIGURATION
Model 130 series RF transceivers can be configured to operate as
either a Master Transceiver or as a Remote Communication Node
(RCN) And, the mesh network / repeater function can be turned on
or off (factory default is off). Because of the physical configuration
differences in the two modelsit is unlikely to be necessary to alter
the Master Transceiver / RCN configuration.
Twoconfiguration property tablesare accessible by the user. The
first property table setsMode of Operation, The secondsetsthe
mesh network / repeater function on or off. The configuration
tables that followprovide operational descriptions and factory
default settings. Selections are indicated through the FLASH-
COUNT of LED’s D1and D2. (Refer to Figure 1 and 2 above.)
D2repeatedlyflashes 1 or2times to indicate the property table
that is active. D1flashes 1 or 2times to indicate thespecific
operational ‘property’ selected.
(Refer to Figure 1 or 2 for button and LED locations)
PB3 (Configuration Setup)will switch the unit into and out ofthe
configuration mode. Holding PB3 down for approximately 3-
seconds will take you into the configuration area. To leave the
configuration area, simply press and release PB3. PB2selects
configuration table 1 or2, which is indicated by D2FLASH-
COUNT.
PB1selects theconfiguration property as indicated by D1FLASH-
COUNT. Pressing PB3to leave the configuration area will save
changes made. To review or change the configuration, refer to the
configuration tables below for descriptionsand perform the
following:
1. Press and hold PB3 until LED indicator lamps D2 & D1 flash
alternately. (NOTE: At any time during the setup process PB3 can
be pressed again to return to normal operation.)
2. D2will flash once indicating Table 1, Operating Mode
configuration, followed by D1flashing 1 or 2times indicating the
specific configuration in Table 1 that is currently active. (NOTE:
D2 and D1 will flash repeatedly to indicate the Table and the
configuration.) Pressing PB1will advance the configuration option
by one. Press PB1until the FLASH-COUNT corresponds to the
desired configuration. (Refer to Table 1.)
3. Press PB2to advance to Table 2, Message Repeat
configuration. D2willflash2 times, followed by D1 flashing 1 or 2
times depending on how it is currently set. Press PB1until the
FLASH-COUNT corresponds to the desired configuration.
4. Press PB3 to return to normal node operation, saving any
configuration changes you’ve just made.

INSTALLATION / LINKING
A Master Transceiver and Remote Communication Node will not
operate as a system until they are linked together through the
installation linking process. The linking process binds one or more
RCN units to a Master so that they will communicate with each
other as a control system. There is no practical limit to how many
RCN units can be linked to a Master. Once linked,Remote
Control Nodeswill only respond to the Master they are linked to.
Message traffic from other Master Transceiversand nodes will be
ignored. Master Transceivers and associated RCN unitswill not
interfere with or be affected by any other Masteror RCN in
adjacent apartments, hotel rooms or neighboring homes. Linking
information is stored in non-volatile memory —It is not necessary
to re-link a Master and RCN if power is lost.Upon restoration of
power the units will continue to communicate as before.
NOTE:
If multiple installation teams are performing the linking process at the same
time, coordinate theactivity to avoid the possibility of installers
simultaneously attempting to link RCN units.
For immediate visual confirmation of a successful link, it is recommended
that RCN’s and Master Transceivers are linked in close proximity to each
other.
LINKING PROCESS
Start the linking process by simultaneously pressing PB2 and PB3
on the Remote Control Node you wish to associate with a given
Master Transceiver. LED’s D2 and D3 will light and stay on for
approximately 5-seconds after you have simultaneously pressed
both buttons indicating an installation link period window is open.
Simultaneously press PB2 and PB3 on any RCNcircuitboard to
initiate an installation period.
At any time during the link period window, press PB2 on the
Master Transceiver. A successful link is indicated by green LED
D4 flashon the RCN. Anunsuccessful link or installation period
timeout is indicated by red LED D5 flash.

RF COMMUNICATION TEST
After RCN units have been linked to a Master and installed on
thermostat bases, a communication test should be run to ensure a
reliable communication path exists between each RCN and its
Master Transceiver.
Initiate a 5-second communication test with the Master transceiver
by pressing PB2 on the RCN under test. After the 5-second test
period a PASS/FAIL indication is given:
?Green LED (D5) flash = PASS
?Red LED (D4) flash = FAILED
Each model 130 wireless RS485/422 RCN can be operated with
or without mesh (message repeating) functions turned on. Factory
default is repeater OFF. With the repeater function off, the Master
Transceiver must be able to directly communicate with each of its
RCN’s. While the repeater function allows the system to over
come RF range limitations, unnecessary repeats adds traffic to the
network. A better use of the function is to selectively enable it.
Figure 3 is an example of using the repeater function selectively.
In this example case, a Master Transceiver directly communicates
with RCN 1, 2 and 3. RCN 4 and 5 however are out of range.
RCN 3 is the closet RCN to 4 and 5. Its repeater function is
enabled, forming the bridge between the Master and RCN units 4
and 5.
