Consultfactory for information.The EIM includes the following features:●● Network time and location synchronization●● 250 Global Time Schedules●● 30 Holidays●● Global Alarm TableThe EIM comes in a desktop enclosure and is connected toEthernet and PRC RS-485 networks. A personal computerwith PRC software can be located anywhere on theEthernet network. The EIM will communicate at 10Base-Tand must have a fixed IP address assignment on theEthernet network. On the front of the EIM are connectorsfor CAT5, a removable RS-485 network connection (Belden3105A network cable), and a 4-pin network diagnosticconnection for local access to the device. The EIM ispowered by using the provided +15 Vdc power supply thatplugs into any standard wall outlet. It also has an On/Offswitch, power indicator LED and communication indicatorLED. Pow-R-Command Lighting Optimization Software(PRCLOS) is required to access the system.Ethernet networkThe PRC1500E and PRC2000E controllers are connected toan Ethernet network by using the RJ-45 connector locatedin the low voltage compartment. See Figure 24.Figure 24 PRC-E Ethernet RJ-45 PortSee Figure 25 for a typical Ethernet network architecture.Figure 25 Ethernetotee:N Configuring the controller’s network parameters arerequired before establishing communications overthe network.Controller configuration can be accomplished by using thefollowing methods:●● Optional backlit color LCD touchscreen display (refer to“LCD touchscreen display programming” on page 17)●● Personal computer direct connection to controllerMaintenance Port (refer to “Connecting personalcomputer to controller Maintenance Port” sectionon page 15Once the controller is configured with required networkparameters, a personal computer on the network canestablish communications with the controller.RS-485 Daisy Chain 2-WireShielded Twisted Pair w/ShieldBelden 3105A or Equivalent
