Description

Sets or queries the current USB device address that is used when making a Flex-on-Flex connection. When you connect the USB cable, FlexDCA automatically discovers a N1000A and stores this address. To actually establish the Flex-on-Flex connection, confirm or set the address with this command, select USB with the :RDCA:CONNect:METHod command, and then make the connection using the :RDCA:CONNect command.
