P5 ProcessorsCOMPONENTSP R O C E S S O R L I N K SEach Processor has several communication links, whichallow the processor to interact with other systemequipment. Some links are designated for specificcomponents, and other links are configurable throughthe HomeWorks® Illumination Software, allowing thesystem to be customised to meet the needs of theproject.Communication Link 1 (8 series processor only): Thislink is designated for communication with ModuleInterfaces. It must be wired in a daisy-chainconfiguration and requires a link terminator at the lastModule Interface when the total cable length exceeds15m (50 feet).Communication Link 2: This link is designated forcommunication between multiple processors. It mustbe wired in a daisy-chain configuration and requiresterminators at both ends of the link when the totalcable length exceeds 15m (50 feet).Communication Links 3 and 7 (Link 7 is onlyavailable on the 8 series processor): These links aremulti purpose RS-232 ports. One port is initially usedfor programming the processor. When a port is notbeing used for programming, the RS-232 ports can beused for two-way serial communications with A/Vequipment, touch screens, security systems, HVAC, andhome automation controls. Maximum cable length is15m (50 feet).Communication Links 4, 5, and 6: Each of these linkscan be configured to communicate with one of thefollowing: keypads and interfaces, Maestro ® locallighting controls (via an H48 dimmer interface), SivoiaQEDTM drives (via HW-Q96 interface) or GRAFIK Eye ®preset local lighting controls and Wallbox PowerModules.Communication Link 8: On an 8 series processor, thislink may be configured for any of the functions listedfor links 4, 5, and 6 or as a hybrid signal repeaterlink. On a 4 series processor, this is an optional linkonly for hybrid signal repeaters.Communication Link 9:This link is an ethernet port. The ethernet port can beused for uploading programming information orcommunication with other systems, such as A/Vequipment, security systems, HVAC, and homeautomation equipment. Maximum cable length is 100m(328 feet).Figure 1 - 8 Series Processor Link IdentificationFigure 2 - 4 Series Processor Link Identification8.4 www.lutron.com
