5-3. IEEE-488 (GPIB) Bus Operation
The internal functions of Model 8310 are controlled via an IEEE-488 bus and an external controller. The front
panel LSN and RMT indicators (Figure 2) are used as status indicators for the Model 8310
Programmable
Interface’s
IEEE-488 bus operation. During bus operation a flashing LSN indicates that the Model 8310 is receiving. The RMT
indicator is illuminated when the Model 8310 is in the remote state.
The table below summarizes the IEEE-488.1 interface functions that are implemented by the Model 8310.

The GPIB interface of the 8310 is IEEE-488.2 compliant. The 8310 recognizes instructions and data sent via
the GPIB interface in the form of program messages comprised of ASCII characters. A program message is
comprised of a sequence of program message units separated by semicolons and terminated by a line terminator
(LINE END). A line terminator takes the form of an ASCII LF character (0AH), or an EOI signal asserted with the last
data byte, or both. The 8310 program message units may be divided into two syntax groups: commands and queries.
Refer to the section on command syntax for more information.
