Digital Gamma-Ray Spectrometer User’s Manual 932502G / 0618
For commands across the Ethernet interface, an optional checksum may be added to the end of
any command sent to MCB API. The checksum is a 1-byte unsigned integer sum of all of the
characters in a command, treated as unsigned integers, up to and including the comma or
space(s) that separates the checksum from the command. The checksum simply appears as an
extra parameter added to the end of the command parameter list. For commands that do not nor-
mally have parameters, the checksum appears as the only parameter separated from the header by
one or more spaces. All optional parameters must be included in a command if a checksum is to
be provided so that the checksum is not mistaken by the MCB API as a parameter. For example,
the SET_WINDOW command must include the two optional parameters, start and length, if the
checksum is provided (e.g.,
SET_WINDOW 0,16384,209 ).
7.1.2. USB-Interface Error Codes
On each completion of the command, the MCB returns a macro error code and micro error code.
The macro error code represents the general class of error with 0 meaning no error, and the
micro error code represents the sub-class of error with 0 meaning no error. In case of error
condition, you can use the
MIOGetLastError
(DLL interface) or
GetErrMajor, GetErrMinor
(ActiveX control interface).
Macro error codes:
0 Success
1 Power-up just occurred
2 Battery-backed data lost
129 Command syntax error
131 Command execution error
132 Invalid Command
For macro code 129 (syntax error) or 131 (execution error), the following apply:
1 Invalid Verb
2 Invalid Noun
4 Invalid Modifier
128 Invalid first parameter
129 Invalid second parameter
130 Invalid third parameter
131 Invalid fourth parameter
132 Invalid number of parameters
133 Invalid command
