C Language Based ViewPAC (MiniOS7 Inside)
The ViewPAC, VP-211x and VH-211x series, has a 16-bit CPU, 128 x 64 resolution graphic display, silicon rubber keypad, communication ports of Ethernet, RS-232, RS-485 and 3 I/O expansion slot. It also equipped a DOS-like OS, MiniOS7. Users can use C compilers to create 16-bit executable files (*.exe) to develop a program then download it to the controller. The user can choose Turbo C 2.0 or Turbo C++ 1.0.1 to compile this application program and generate a execution file. This execution file can be download to VP-211X and VH-211x via RS-232 port or ethernet port. We recommend the user to use Turbo C++ 1.01.

There are many demo programs for reference. Beside that, for TCP/IP programming, we provide a TCP/IP server template that named XServer. It is very powerful, easy use and flexible tool that can save 90% developing time.
