End of Reading EOI Jn
The End Or Identify (EOI) line is one of five bus management lines on the IEEE
488 Bus. It is used by a talker to indicate the end of a multiple byte transfer sequence.
The controller can change the End of Reading EOI mode by programming the
Analyzer488 from the bus. A reading is a single data point and a waveform (any
factory waveform from 0 to 20) is made up of 256 readings. The End of Reading EOI
command allows the Analyzer488 to assert or not assert the EOI line when the last byte
of each reading is sent to the controller.
In the J0 mode, the EOI line is asserted by the Analyzer488 on the last byte of
every reading. In the J1 mode the EOI line is not asserted by the Analyzer488.
SYNTAX: J0 EOI enabled, assert EOI on end of reading
J1 EOI disabled, do not assert EOI on end of reading
(default)
J? Return current End of Reading EOI selection
EXAMPLES: PRINT#1,"OUTPUT10;J0X" assert EOI on end of reading
PRINT#1,"OUTPUT10;J?" query EOI mode
PRINT#1,"ENTER10" request data
INPUT#2,A$ get data
PRINT A$ J0 is displayed on the front panel
