End or Identify (EOI) Kn

The EOI line is one of five interface management lines on the IEEE 488 Bus. It

is used by a talker to indicate the end of a multiple byte transfer sequence. At power-
on, the setting of Switch S1 determines the default EOI mode. The controller can
change the EOI mode by programming the Digital488 from the bus. In the K0 mode,
the EOI line is asserted by the Digital488 on the last byte of every bus output string.
In the K1 mode the EOI function is disabled (except when using the binary modes
[F4 and F5] ).

K0

EOI enabled, assert EOI on last byte transferred

K1

EOI disabled, do not assert EOI on last byte transferred

Example:

OUTPUT 718;"K1X"

disables EOI on last byte
