LaserSpeed 8000/9000 I/O Module Instruction HandbookIntroductionIntroductionThe LaserSpeed I/O Module is used to translate the serial output data, Speed,Length and Gauge Status, from a LaserSpeed 8000 or 9000 Series Gauge to aparallel output. Optional Profibus and Ethernet field bus are also available in theI/O Module. The I/O Module connects to the LS9000/LS8000 gauge through agauge cable via an RS422 connection, and provides a pass-through connectorfor direct access to all the Inputs and Outputs of the LS9000/LS8000 SeriesGauge. A Light Stack connector provides signals to drive a visual indicator (alight stack) to display the status of the gauge. The I/O Module can also be usedcalculate the Elongation Ratio/Differential Speed between two LS8000/LS9000Series gauges. In addition, the I/O Module can be used to synchronize theoutputs of multiple gauges to output their data at the same time.I/O Module Front PanelPart No. 93342 / Drawing No. 0921-01516Page 7 of 84Revision E (Dec 2013)

All I/O Modules except for the last I/O module in the Daisy Chaincalculate the Elongation Ratio or Differential Speed. The last I/O module in theDaisy Chain always outputs Length on the Length/Elongation port. All other I/OModules output Elongation Ratio if the port is configured for Auto-ElongationMode. The I:Elongation command is used to configure this mode. By default,the I:Elongation setting should be set to 1 on all I/O Modules. This will causethe I/O Module to automatically output Elongation if it is being calculated. Seethe Elongation/Synchronization section for more information about Elongation.Note: Elongation Ratio will only be calculated when two gauges are synchronizedtogether by connecting the Sync Out of one I/O Module to the Sync In of theother I/O Modules.Part No. 93342 / Drawing No. 0921-01516Page 10 of 84Revision E (Dec 2013)

LaserSpeed 8000/9000 I/O Module Instruction HandbookInstallationParallel OutputsData is updated to the bus in one of two modes. The first is called "Data Ready"mode and the other is called "Data Request" mode. In "Data Ready" mode, thesystem will automatically update the data on the Parallel Output Bus each UserUpdate Period. In "Data Request" mode, the system will update the data on theParallel Output Bus only when a Data Requested Signal is received on the DataRequest Input Pin. There are Data Request Input Pins on the Parallel Length/Elongation port and the Parallel Velocity port. The data output mode isconfigured by I:AckMode serial command:CommandParallel Port Mode I:AckMode 0Data Ready Mode I:AckMode 1Data Request ModeData Ready ModeIn Data Ready mode, the I/O module outputs data each time a new measurementis received from the LaserSpeed gauge. An optically isolated signal called "DataReady," located on the Length/Elongation and the Velocity Output connectors,are provided to indicate when data has been upated and is valid. The DataReady pulse indicates that the data bus has been updated with new data and thatthe signals on the bus are completely settled. Both Data Ready True (RisingEdge Trigger, signal driven from ground to Voltage high) and Data Ready False(Falling Edge Trigger, signal driven from Voltage high to ground) are provided.When using Data Ready True, data should be read from the bus on the risingedge of the signal, and when using Data Ready False, data should be read onthe falling edge. Either the leading edge or the active level of the signal can beused to trigger a read by your interface.Ringing on the line can occur if the cable is not properly terminated. This cancause the data to be unstable during the time of the active edge of the data readysignal. Allow for extra settling time if ringing occurs.SignalActivityData Valid On:Data Ready (True)Active HighRising EdgeData Ready (False)Active LowFalling EdgeData is valid from the time that the Data Ready signal is asserted until the timethat the next data point is received from the gauge. This time varies dependingon the gauge’s Update Rate configuration setting.
