Support Software

Standard COM Driver Software COM Setup Disk (Bundled)

Under Windows, this software allows you to use the serial ports on the

converter as if they were standard COM ports on the PC. By connecting

additional products, you can use COM ports in the range COM1 -

COM256. Under Windows, the serial ports can be accessed using the

standard Win32 API communication routines (CreateFile( ), WriteFile( ),

ReadFile( ), and SetCommState( ), etc.) The serial ports are also

compatible with the Visual Basic communication control (MSComm).

Supports the communication class of .NET Framework (SerialPort

class).

For more details on the supported OS, applicable language and new

information, please visit the CONTEC’s Web site.
