5015 B.U. Bowman Drive Buford, GA 30518 USA Voice: 770-831-8048 Fax: 770-831-8598 FCC Part 15.249 Certification Test Report FCC ID: U22GSESWW FCC Rule Part: 15.249 ACS Report Number: 07-0016-15C Manufacturer: Convia – A Herman Miller Company Model: Wireless Switch Manual Convia tm – A Herman Miller Company ConviaRF Wireless Switch System User Guide March 2007 Convia tm – A Herman Miller Company Components There are two types of components involved in implementing a ConviaRF Wireless Switch System. They are the ConviaRF Wireless Switch and Wireless Switch Coordinator. ConviaRF Wireless Switch (SWW) The Wireless Switch (SWW) can be used in the same way as the wired Convia switch (###). Like the wired switch, the wireless switch can be used to control lights and other devices that are connected to Convia Smart Connectors. Just like the wired switch the user manually presses the up or down switch to turn selected light fixtures on and off. The Wireless Switch It can be programmed to operate a wide configuration of light fixtures and also used to control dimming levels. The Wireless Switch will operate at a minimum of 75 feet from a ConviaRF Wireless Coordinator. Convia tm – A Herman Miller Company ConviaRF Wireless Coordinator (WSC) The Wireless Switch Coordinator (Coordinator) acts as the network interface for the ConviaRF Wireless Switch. It provides a gateway to the ConviaNET communications network and allows ConviaRF Wireless Switch to be an active participant on the network. A key function of the Wireless Switch the Coordinator is that it monitors the ConviaNet communications network for relevant message commands that apply to the Wireless Switch. This allows the Wireless Switch to connect to the network less frequently and increases battery life. ConviaRF Dip Switches ConviaNet RJ45 Ports Antenna Convia tm – A Herman Miller Company How to setup your ConviaRF Wireless Switch System Installation/Setup a. A maximum of 10 ConviaRF Switches can be used with a single Wireless Coordinator. b. Up to 16 ConviaRF Coordinators can be used in one space by setting each to a different dip switch setting. c. The minimum range for a ConviaRF Wireless Coordinator is 75 feet. Multiple Coordinators can be used to cover an extended space. d. The Coordinator can be mounted to the Open Grid or any other wall or ceiling location as long as the antenna is five feet away from any potential metal obstructions. e. The ConviaRF Channel must be selected via dip switches on both the ConviaRF Switch(s) and the Wireless Coordinator. The dip switches must match before communications can be established between them. f. To connect the Wireless Coordinator to the Convia network - plug one end of an approved ConviaNet RJ45 cable into a port on the Coordinator and the other into an RJ45 port of a Smart Connector or other ConviaNet device with an available port. The second RJ45 port may be used to connect other specified devices to the Convia network using the approved ConviaNet Rj45 cables. g. Establishing the wireless connection between the wireless switch and the coordinator is achieved by holding the up and down buttons on the wireless switch until the ConviaIR Wireless Connection indicator light turns solid green. A blinking green light means the wireless switch is attempting to Connect to a ConviaRF Wireless Coordinator. If the light blink rate increases, and then the light goes out this indicates that the wireless connection failed. This means either the Coordinator has reached the maximum of 10 switches or the Wireless Switch is not in range of a Coordinator. Connection states communicated by the Wireless Connection Indicator LED are as follows: i. Connection in process – Green LED light is blinking ii. Connection process Fails – Green LED light blinks faster then goes off iii. Connection successful, Active State – Green LED light on solid iv. Connection successful, Idle State – Green LED off after being on solid for 5 minutes Convia tm – A Herman Miller Company Operation of ConviaRF Wireless Switch Once linked, the ConviaRF Wireless Switch will respond and act similar to a wired Convia Switch as detailed in the “Convia Lighting User Guide”. With the following notable exception: A previously Connected but idle wireless switch will not respond to wand commands directed at it but will respond (though in a slightly delayed fashion) to wand command directed to other non-wireless devices that had previously been Linked to it. An idle connected Wireless Switch will continue to send on/off and dimmer commands when its buttons are pressed. Once in the active state, A ConviaRF Wireless Switch will respond to wand commands similar to the wired Convia Switch. The CoviaRF Wireless Switch, when in an energy saving idle state, will not be actively connected to the network until one of the following happens: h. The connection is made active by holding the up and down buttons on the wireless switch until the ConviaIR Wireless Connection indicator light turns solid green. i. A programming sequence occurs with a Convia Smart Connector device which the Wireless Switch has previously been Linked to. (There may be a slight delay to moving from idle to active state, up to 2 seconds) Convia tm – A Herman Miller Company How to use the ConviaRF Wireless Switch Connect a ConviaRF Wireless Switch and Light This procedure is the foundation for creating a lighting configuration. It establishes a connection between a Convia switch and a light fixture. 1. To start the programming sequence, use the link button on the wand to select the switch. The Status Indicator Light turns on. 2. Use the link button to select the Smart Connector that controls the light. The Status Indicator Light turns on. Both Status Indicator Light lights stay on until the programming is concluded, as follows: 3. Use the link button to select either the Smart Connector or the switch a second time. The Status Indicator Lights on both the switch and Smart Connector turn off. Th…
