Public Shared Function ValidateAlpacaAddress (
ipAddressString As String,
portNumber As Integer,
uniqueId As String,
<OutAttribute> ByRef foundDevice As AscomDevice,
Optional logger As ILogger = Nothing
) As BooleanParameters
- ipAddressString String
- The IP address of the Alpaca device as a string.
- portNumber Int32

- uniqueId String
- The unique ID of the Alpaca device.
- foundDevice AscomDevice
- An AlpacaDevice instance containing the new IP address and port of the Alpaca device when returning false and the device is found on another address. Otherwise null.
- logger ILogger (Optional)
- Optional logger for debug messages. Defaults to null, which suppresses logging.
Return Value
BooleanTrue if the device exists on the supplied IP address and port, otherwise false. If a device with the same unique ID is found on a different address, foundDevice will be set to that device.
Remarks
When the device is found on multiple paths, this method returns the address of the device that is closest to the original address e.g. is on the same sub-net.
