Remarks


You do not need to use a selector string to configure or read this attribute for the default signal instance. On a MIMO session, use port::<deviceName>/<channelNumber> as a selector string to configure or read this attribute per port. If you do not specify port string, this attribute is configured for all ports. Refer to the Selector String topic for information about the string syntax for named signals.

The default value is 0.
