TOS6200A/6210 GPIB and RS-232C 6-5
Writing messages
• Provide a space (ASCII: 20h) between the message header and the data.
• When there is more than one piece of data, connect them using “,” (ASCII:
2Ch).
• To connect one message to another, use “;” (ASCII: 3Bh).
• To describe data using hexadecimal numbers, add “#H.”
Example: To describe the decimal number “10” using a hexadecimal number,
write “#H0A.”
• When “@” is added to the end of a message, the hold-off status is retained until
execution of the message is completed.
However, in the event of a message terminator with only EOI, use '@@'.
Acknowledgment messages (RS-232C)
The acknowledgment message is peculiar to the RS-232C interface. This message is
sent from the tester to a controller. It indicates that a program message has been pro-
cessed.
An acknowledgment message is a character string of ASCII code which is com-
posed only of a header. There are two types such messages:
•
OK: Normally terminated
• ERROR:Abnormality occurring, such as a syntax error
Through the use of a SILENT command, it can be specified whether to return an
acknowledgment message.
