MONO_SetPosition
short __stdcall MONO_SetPosition(long Handle,unsigned short Node,long Position);
call this function to set an absolute user defined position. Wavelength is not linear to position
Returns 0 in case of error else 1
long Handle: Handle of the comport returned by MONO_OpenConnection
unsigned short Node: must be 0 (zero)
long position: absolute position value
MONO_GetPosition
long __stdcall MONO_GetPosition(long Handle,unsigned short Node);
call this function to get the absolute position in steps (arbitrary unit)
long Handle: handle of the comport returned by MONO_OpenConnection
unsigned short Node: must be 0 (zero)
Direct Serial Communication (ASCII Commands)
If you do not want to use the DLL-functions you can directly communicate with the MonoScan2000
using ASCII commands.
► Procedure
The following steps are required:
1. Establish serial connection from PC to MonoScan-2000
2. Read device information such as calibration data and serial number (not necessarily needed)
3. Set an absolute position. Repeat this step as needed.
4. Close serial connection
