Prolon VC2000 Series - LEDs; Bias and Terminating Resistors; Firmware Compatibility

8. LEDS
ThePL-TREE-COMcomesequipedwithveLEDstoindicatedevicestatus.(Figure6)
8a) HBEAT (BLUE): This LED simply indicates that the device is powered and operating. It should blink once every second,
regardless of RS485 or Wireless communication.
8b) CONN (BLUE)*: This LED indicates if other devices have been found on the same subnet as this device. If so, then the
devices are ready to share their RS485 information.
8c) ROOT (YELLOW): This LED indicates if this device has been set as a “ROOT” using dipswitch #8. When the LED is ON,
    thisdeviceissetastheROOTforitssubnet.IftheLEDiso,itisinsteada“LEAF”.
8d) SND (RED): ThisLEDindicatesifdataisbeingtransmittedontheRS485bus.Blinkingoccursinquickshortbursts.
8e) REC (GREEN): ThisLEDindicatesifdataisbeingreceivedfromtheRS485bus.Blinkingoccursinquickshortbursts.
*Once a successful connection is established between a “ROOT” and one or more multiple “LEAF” devices, their
individual CONN blue lights will turn on. The connection process may take up to 7 minutes to complete.

9. Setting bias and terminating resistors
ThePL-TREE-COMcomeswithjumperstoenableRS485biasandterminatingresistors.Biasandterminatingresistors
are used to stabilize an RS485 network. Terminating resistors should be placed at each extremity of an RS485 bus. Both
bias resistors should be activated at a single node on the RS485 bus, but the location of the node is not important
  ThejumpertoactivatetheresistorsareidentiedonthePL-TREE-COMviathefrontlabel.Theresistorsareactivatedwhen
  thejumpercoversbothheaderpinsforagivenresistor.
10. Firmware compatibility
ThePL-TREE-COMisdesignedtoworkwithsamegenerationproducts(v.7.5.0orlater),butcanberetrottedintoexisting
systems, provided that the controllers using TREE-COM modules are compatible. This is especially important with Modbus
  “Master”devices,thatmustcomplywiththeTREE-COM’sspeciccommunicationcaracteristics.
10a) WhenaPL-NC2000ispresent,itmusthavermwareversion7.5.0orlatertosupportTREE-COMcommunication.
10b) AnyDigitalwallsensor(T200/T500/T1000)connectedtoaTREE-COMmusthavermwareversion7.5.0orlaterto
support TREE-COM communication.
10c) Other Modbus Master controllers (RTU, HP, etc.) using older rmware may still work properly with TREE-COM
modules. It is strongly recommended however to update them for best communication performance
10d) Followercontrollersarenotaectedbyrmwareversion,allarecompatiblewiththeTREE-COM.
