Message Terminators
This manual uses <EOI> (End or Identify) to represent a message termina-
tor.
Symbol Meaning
<EOI>
Message terminator
IfyouuseaGPIBnetwork,<EOI> can be the IEEE Std 488 EOI interface
symbol or LF (line feed). When using GPIB, the OA 5000 always accepts the
EOI interface symbol as an input message terminator.
The end-of-message terminator may be either the END message (EOI
asserted concurrently with the last data byte), the ASCII code for line feed
(LF) sent as the last data byte, or both.
The end-of message terminator should not immediately follow a semicolon
(;).
The OA 5000 always terminates responses to queries with linefeed and EOI
asserted.
