END
176 Chapter 6 Command Reference
END
The END command enables or disables the GPIB End Or Identify (EOI)
function.
Syntax END [control]
control The control parameter choices are:
Power-on control = OFF.
Default control = ALWAYS.
Remarks • Each reading output to the GPIB in ASCII format is normally followed by cr,lf
(carriage return, line feed). The cr lf indicates the end of transmission to most
controllers. Readings output in any other format do not have the cr lf end of line
sequence. When using the ASCII output format and multiple readings are
recalled from reading memory using the RMEM command, the multimeter
places a comma between readings. In this case, the cr,lf occurs only once,
following the last reading in the group being recalled. Commas are not used
when readings are output directly to the bus (reading memory disabled), when
readings are recalled using "implied read", or when using any other output
format.
• Check your computer manual for information on how your computer responds
to the EOI line.
• If END ALWAYS is specified for the high-speed mode, the EOI mode
automatically becomes ON while the readings are being taken. Following
completion of the readings, the EOI mode returns to ALWAYS. Refer to
"Increasing the Reading Rate" in Chapter 4 for more information on the
high-speed mode.
• Query Command. The END? query command returns the present EOI mode.
Refer to "Query Commands" near the front of this chapter for more information.
