–111
Header separator error
A character which is not a legal header separator was encountered while
parsing the header.
–110
Command header error
An error was detected in the header. This message is used when the device
cannot detect the more specific errors described for errors –111 through
–119.
–109
Missing parameter
Fewer parameters were received than required for the header. For
example, the
*ESE
common command requires one parameter, so receiving
*ESE
is not allowed.
–108
Parameter not allowed
More parameters were received than expected for the header. For example,
the
*ESE
common command only accepts one parameter, so receiving
*ESE
0,1
is not allowed.
–105
GET not allowed
A Group Execute Trigger was received within a program message (see
IEEE 488.2, 7.7). Correct the GPIB controller program so that the
GET
does
not occur within a line of GPIB program code.
–104
Data type error
The parser recognized a data element that is not allowed. For example,
numeric or string data was expected, but block data was encountered.
–103
Invalid separator
The parser was expecting a separator and encountered an illegal
character. For example, the semicolon was omitted after a program
message unit.
–102
Syntax error
An unrecognized command or data type was encountered. For example, a
string was received when the device does not accept strings.
–101
Invalid character
A syntactic command contains a character which is invalid for that type.
For example, a header containing an ampersand, such as “SETUP&”. This
error might be used in place of error numbers –114, –121, –141, and some
others.
