Keithley 2002 User Manual

IEEE-488 Reference
3-28
the response message for a program message that contains four single item query
commands:
0; 1; 1; 0
3. Response Message Terminator (RMT): Each response message is terminated with an LF
(line feed) and EOI (end or identify). The following example shows how a multiple
response message is terminated:
0; 1; 1; 0 <RMT>
Message exchange protocol
The message exchange protocol can be summarized by the two following rules:
Rule 1. You must always tell the Model 2002 what to send to the computer.
The following two steps must always be performed, in this order, to send information from the
instrument to the computer:
1. Send the appropriate query command(s) in a program message.
2. Address the Model 2002 to talk.
Rule 2. The complete response message must be received by the computer before another
program message can be sent to the Model 2002.
