MODEL 13000 Application Guide 3 INTRODUCTION The model 130 series RF transceivers are designed to provide a wireless, mesh network RS485/422 interface over 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 thermostat supports a hardwired RS485/422 serial communication channel such as that provided by an NI-700 serial port. Through the NI-700, information can be received from 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 wireless communication 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.
MODEL 13000 Application Guide 4 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 models it is unlikely to be necessary to alter the Master Transceiver / RCN configuration. Two configuration property tables are accessible by the user. The first property table sets Mode of Operation, The second sets the mesh network / repeater function on or off. The configuration tables that follow provide operational descriptions and factory default settings. Selections are indicated through the FLASH-COUNT of LED’s D1 and D2. (Refer to Figure 1 and 2 above.) D2 repeatedly flashes 1 or 2 times to indicate the property table that is active. D1 flashes 1 or 2 times to indicate the specific operational ‘property’ selected. (Refer to Figure 1 or 2 for button and LED locations) PB3 (Configuration Setup) will switch the unit into and out of the 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. PB2 selects configuration table 1 or 2, which is indicated by D2 FLASH-COUNT. PB1 selects the configuration property as indicated by D1 FLASH-COUNT. Pressing PB3 to leave the configuration area will save changes made. To review or change the configuration, refer to the configuration tables below for descriptions and 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. D2 will flash once indicating Table 1, Operating Mode configuration, followed by D1 flashing 1 or 2 times 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 PB1 will advance the configuration option by one. Press PB1 until the FLASH-COUNT corresponds to the desired configuration. (Refer to Table 1.) 3. Press PB2 to advance to Table 2, Message Repeat configuration. D2 will flash 2 times, followed by D1 flashing 1 or 2 times depending on how it is currently set. Press PB1 until 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.

MODEL 13000 Application Guide 6 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 Nodes will only respond to the Master they are linked to. Message traffic from other Master Transceivers and nodes will be ignored. Master Transceivers and associated RCN units will not interfere with or be affected by any other Master or 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 the activity 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 RCN circuit board 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 flash on the RCN. An unsuccessful link or installation period timeout is indicated by red LED D5 flash. PB1 PB3 PB2 D1 D2 D3 PB1 PB3 PB2 D1 D2 D3
MODEL 13000 Application Guide 7 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.
