If you take a look at the help file, it states that the values for the firmware returned by the get motion board information are in the following format:
Firmware Version (10) string out, numeric out Version-build code (MMmmbbbb)
DSP Version (11) string out, numeric out Version-build code (MMmmbbbb)
FPGA Version (12) string out, numeric out Version-build code (MMmmbbbb)
FlexMotion Board Class (13) numeric out FlexMotion-7344 (1)
FlexMotion-7334 (2)
FlexMotion-7350 (3)
FlexMotion-7342 (4)
FPGA Version (14) string out, numeric out Version-build code (MMmmbbbb)
where
MM = the major version number,
mm = the minor version number, and
bbbb = the build number.
These values are returned in hexadecimal code, and it seems you are r
eading yours in decimal. This is an omission in or documentation and a request to fix it has been filed.
