Contec COM-2PC-PE - Isolated 2Ch RS-232C Serial I/O Board for PCI Express

Adds 2 Isolated RS-232 Ports to a PC via Standard PCI Express Slot

Introduction

Contec COM-2PC-PE is a PCI Express bus-supported board designed for extending RS-232C compatible serial communication functionality on your PC. It has two RS-232C-standard serial ports. Higher noise-resistant models with isolation between channels and between PC and bus line as well as a surge protection circuit for communication ports. With a 128byte built-in FIFO buffer for transmission and reception of each channel, the product supports a baud rate of up to 921,600bps. It also comes with a Windows/Linux driver, which allows boards to be used as OS-standard COM ports.

  • It has two RS-232C-standard serial ports. Baud rates from 2 to 921,600bps can be set for each port. When using the bundled [Standard COM Driver Software] and [Driver library API-PAC(W32)], baud rates from 15 to 921,600bps can be set.
  • Comes with a driver software that allows the boards to be used under Windows / Linux in the same way as COM ports on the PC. Under Windows, the product supports the OS-standard Win32 API communication function as well as Visual Basic MSComm. Under Linux, OS-standard tty driver's standard-function can be used. In addition, supplies a diagnostic program to confirm hardware operation and to perform a communication test with equipment.
  • The channels are electrically isolated from each other and from the PC. As isolation is provided between channels as well as isolation of the bus, this prevents electrical noise between channels as well as between the PC and external circuits. As surge protection is provided on all signal lines, you can safely use the boards in environments where you are concerned about surges causing incorrect operation or damage to the PC.
  • Up to 16 boards can be mounted on a single PC. COM1 - COM256 can be set using the device manager.
  • It put a buffer memory of 128byte for use of the transmission, and a buffer memory of 128byte for use of the reception on each channel. The buffer memory helps high-speed communication and CPU load reduction by data transmission and reception time in an FIFO form. It can set FIFO use presence, FIFO trigger size by device manager. It can realize the most suitable performance by doing the adjustment trigger size that accepted a system.
