X907 Output Signal Name

Laser Input Signal Name

Core

AppendPower(UInt16)(power-level)

ANALOG1

Power Center

Ring

AppendDacValue(Dac1, power-level)

ANALOG2

Power Ring

Caution note  Caution

  • The power level of the ANALOG1 and ANALOG2 signals is never automatically reset to zero.

  • Each signal independently retains the power level that was last assigned to it.

  • Changing the power level of one of them leaves the other signal unaltered.

  • All power level changes for these signals must be individually and explicitly commanded, either via AppendPower(UInt16) or via AppendDacValue.

The recommended signal configuration and usage, shown above, are not the only ones possible.

For your application you might prefer, for instance, to set the power-level for the Ring laser unit with the AppendPower(UInt16)(power-level) command.
For this, and assuming that the rest of the configuration remains unchanged, you would need to

Alternatively, you could simply re-wire the hardware signals on the physical connectors, thus swapping the Core/Ring assignment without requiring any changes to your application code.
