For DOS users, the S1 DIP switch acts as Board ID. When there are two or more multi-port serial cards in a single system, it is difficult to identify individual card number.

To install your VXC series cards, complete the following steps: 1. Turn off your computer 2. Remove all covers from the computer 3.

  • Page 16: Software Installation

    Software Installation ICP DAS provides following device drivers for most operation systems such as MS-DOS, Windows NT 4.0 and Windows 2000/XP/2003. These Windows drivers provide full interrupt-driven, buffered I/O for each COM ports. And also supports the Plug & Play mechanism for easy installation. VxCard DOS Lib: Programming library files and sample programs for DOS.

  • Page 17: Dos Lib

    3.1 DOS Lib Microsoft provides standard Win32 APIs for Windows 9x/NT/2K/XP/2003 users to access the COM ports. But DOS did not have such standard APIs, thus ICP DAS provides library functions under DOS for the VXC cards. Which provides easy programming interfaces and sample programs (include source code) that written in Turbo C.

  • Page 38: Interrupt Operation

    4.3 Interrupt Operation There are two interrupt sources in the VXC cards. They are named as INT0 and INT1. Their signal sources are as follows: INT0: UART 0 interrupt output INT1: UART 1 interrupt output If only one interrupt signal source is used, the interrupt service routine doesn’t need to identify the interrupt source.
  • Page 39 4.3.1 Interrupt Block Diagram VXC Card INT\ INT_CHAN_0 Level_trigger INT_CHAN_1 (to PCI slot) initial_low active_high The interrupt output signal of the VXC card, INT\, is Level-Trigger and Active_Low. If INT\ generates a low_pulse, the VXC card will send an interrupt signal to the PC only once.

The only difference between INT0 and INT1 is that the INT_CHAN_0 signal source comes from the UART 0 interrupt output, and the INT_CHAN_1 signal source comes from the UART 1 interrupt output.
