Response Messages sent by the XMP 2600 are comprised of the following elements:
Response Message .........................
a message sent by the XMP 2600 in response to a
Query received from the Controller. The Response
Message is made out of the following elements:
Response Data......
one or more Response Data elements separated by a
Response Data Separator may be included in the
Response Message (as required by the specific Query
that generated that Response). A Response Data
element may be one of the following:
<value> .......
a Decimal Value expressed either in implicit or
explicit point format. In some cases a sign (“+” or “-”)
may precede it.
<int>............
a Decimal Integer Value 0 to 255.
<string>.......
a series of ASCII characters.
Response Data Separator
separates Response Data
elements. It is the ASCII character “,” and may have
<white space> characters surrounding it.
Response Message Terminator
terminates the Response Message.
Together they form a complete transmission. The
Terminator is <CR><LF> (Carriage Return and Line
Feed ASCII codes 13 and 10). For GPIB the <LF>
character will have <EOI> asserted.
