Setpolarizationcontrol; Getpolarizationcontrol - JDS Uniphase SWS15100 User Manual

Function Description
VB prototype Declare Function blinkLED Lib "SWS15100" (ByVal chID%, ByVal OnOff%) As
Long
Input unsigned short chID:
This is the channel selected for blinking.
unsigned short OnOff:
This is Boolean. When the value is 1, blinking is turned ON. When the value is
0, blinking is disabled. The previous state is irrelevant.
Output None
Return Value When there is no error, the function returns zero.
When there is an error, the return value contains the error number.

setPolarizationControl

Function Description
Purpose The setPolarizationControl function is used to set a flag that enables or
disables operations involving any polarization related function.
C prototype int setPolarizationControl( short polarFlag )
VB prototype Declare Function setPolarizationControl Lib "SWS15100" (ByVal polarFlag%)
As Long
Input short polarFlag:
To detect at the receiver side all polarization states sent by the transmitter, the
polarFlag value must be 1. If the polarFlag value is 0, any polarization sent by
the transmitter is seen as polarization state S0.
Output None
Return Value When there is no error, the function returns zero.
When there is an error, the return value contains the error number.

getPolarizationControl

Function Description
Purpose The getPolarizationControl function is used to get the status of the polarization
flag.
C prototype int getPolarizationControl( )
VB prototype Declare Function getPolarizationControl Lib "SWS15100" () As Long
Input None
Output None
