1 - 14LED Sequences and Meaning - ST2070The base contains a green LED that indicates the status of the unit and verifiesits communication with the host system.ST2070 Base LED IndicationBasic Operation of the Cordless SystemThe following system block diagrams illustrate the basic operating componentsof the cordless system.Cordless BaseThe cordless base provides the link between the cordless scanner and the hostsystem. The base contains a control/interface assembly and an RFcommunication module. The RF communication module performs the dataexchange between the cordless scanner and the control/interface assembly.The control assembly coordinates the central interface activities including:transmitting/receiving commands and data to/from the host system, performingsoftware activities (parameter menuing, visual indicator support, power-ondiagnostics), and data translation required for the host system.Sequence MeaningLED on continuously Power on, system idleLED blinks, long duration Power on, diagnostic errorLED blinks, short duration Receiving data from scanner, host, or aux portLED blinks, four long pulses Communication error detectedRF ModuleInternationalAntennaControl/Interface Assembly(Base Circuit Board)ControlUser I/OHost I/OLEDI/O PortsRFPowerMenu I/OMultipointHostAuxBaseHousingCordless Base
