7.2.2. GPIB Address
Each device on the GPIB (IEEE-488) interface must have a unique address. You can
set the address of the 620L to any value between 0 and 30. The address can only be
set from the front panel. The address is stored in non-volatile memory and does not
change when the power has been off or after a remote reset.
The address is set to 9 when the instrument is shipped from the factory.
7.3. Interface Functions
The capability of a device connected to the bus is specified by its interface functions.
These functions provide the means for a device to receive, process, and send
messages over the bus. The interface functions are listed in the chart below.
