Command Set Format
Each command is composed of one alpha character, up to four numeric parameters, and a
command termination character.
command, which is denoted and entered as <LF>. Commands are case-sensitive and must be
entered in upper case only in order to be recognized.
2.2.2.6
IEEE-488 Communications
For IEEE-488 communications, the "End or Identify" (EOI) control line may also be used for
command termination. When sending commands to the Model 75A250A via the IEEE-488 bus,
terminate each command with a <LF>, an EOI, or both. No characters are permitted after the
<LF> or EOI; the 75A250Ainterprets characters following the <LF> or EOI as the start of the
next command.
"Service Request" (SRQ) line is asserted; the operator can then perform a serial poll operation.
The Model 75A250A error code (in binary) is contained in the returned serial poll status byte
(STB). These error codes are defined in Table 2-2.
