SYNC IN and OUT connector
Used to connect multiple I/O modules together for gauge-gauge synchronization,
and Elongation/Differential Speed calculation. The Sync Out connector of one
I/O module connects to the Sync In connector of the next I/O Module with a
straight-through RJ-45 cable.
IN
Connects to the Master I/O module.
OUT
Connects to SYNC IN of the next I/O Module in the Daisy Chain.
Parallel Outputs
STATUS
Parallel Output for Status / Interlock Control / Shutter Control
VELOCITY
Parallel output for Velocity
LENGTH/ELONGATION Parallel output for Length or Elongation Ratio
The LENGTH/ELONGATION port can output either Length or the Elongation
Ratio between two gauges, depending on the I/O Module’s position in the
system. All I/O Modules except for the last I/O module in the Daisy Chain
calculate the Elongation Ratio or Differential Speed. The last I/O module in the
Daisy Chain always outputs Length on the Length/Elongation port. All other I/O
Modules output Elongation Ratio if the port is configured for Auto-Elongation
Mode. 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 cause
the I/O Module to automatically output Elongation if it is being calculated. See
the Elongation/Synchronization section for more information about Elongation.
Note: Elongation Ratio will only be calculated when two gauges are synchronized
together by connecting the Sync Out of one I/O Module to the Sync In of the
other I/O Modules.
