Associated Research OMNIA II 8204 User Manual

112
No more than 15 device loads connected to each bus, with no less than two-
thirds powered on. For example 1 GPIB controller and a maximum of 14 GPIB
instruments.
NOTE: A bus extender, which is available from numerous manufacturers, is
available to overcome these limitations.
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 OMNIA 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 8 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.
