Describing a program message
•
A space (ASCII: 20h) must be inserted between the program header and the
data.
•
If there are two or more pieces of data, connect them using “ , ” (ASCII: 2Ch).
•
To connect program messages, use “ ; ” (ASCII: 3Bh).
• To describe data using hexadecimals, add “#H.”
(Example) The decimal 10 is expressed as “#H0A” in hexadecimal.
• With the GPIB interface, add “@” to the end of a program message to maintain
the HOLD OFF status until the message has been executed. However, in the event
of a command message terminator with only EOI, use "@@".
Acknowledge message (RS-232C)
Acknowledge messages are used only with the RS-232C interface. They are sent
from the tester to the controller, and are used to confirm that the handling of a pro-
gram message has been completed.
Acknowledge messages contain only a header composed of character strings in
ASCII codes. The following two acknowledge messages are used:
• OK
: Normal termination
• ERROR
: Abnormality such as a syntax error
Using the SILENT command message, settings can be made to specify whether to
return an acknowledge message.
