Gauge-Gauge Synchronization

LaserSpeed LS9000 and LS8000 gauges can be synchronized so that their sampling periods are synchronized, and so they update their outputs at the same time.

The simplest method for synchronizing gauges is to connect each gauge to a LaserSpeed I/O module and connect the I/O Modules' synchronization connects together. The I/O Modules will automatically synchronize the gauges and calculate elongation, which can be output in a variety of different ways.

Another method for synchronization is to reconfigure the gauges' High Speed Pulse Output ports and connect the gauges together in a daisy-chain configuration. The gauges will synchronize to each other, but will not calculate elongation. If an elongation calculation is required, the RS232, RS422, or Ethernet output data from each gauge must be collected and calculated in an external PLC or computer.

To configure the High Speed Pulse Output to output the synchronization signal, use LaserTrak to set the High Speed Pulse Config option "A=Pulse Phase A, B=Sync Out". This will replace the pulse output phase B with the synchronization output, and will leave Phase A available for connection to a counter.
