I am using NI 9870 for serial communication. It shows me following errors when trying to connect in VISA test panel. I have cross checked all the paramters like bata bits, parity, bytes and also increased timeout. please help.
ATTRIBUTES :
IS PORT CONNECTED : INVALID PROPERTY VALUE
(VISA: (Hex 0xBFFF001D) The specified attribute is not defined or supported by the referenced resource.)
READ COMMAND:
VISA: (Hex 0xBFFF003A) Unable to start operation because setup is invalid (due to attributes being set to an inconsistent state).
