Selecting Normal or Talk-Only Mode
The RS-232C interface for this instrument has two control modes: normal mode
and talk-only mode. Normal mode is equivalent to the addressable mode for the
GP-IB interface, and enables reception of commands and transmission of data.
Measured or computed data is output on receipt of the “OD” command.
Talk-only mode is equivalent to the talk-only mode for the GP-IB interface. Only
transmission of measured or computed data is allowed. No commands can be
received.
