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.
