2 channel serial communication card
RS-232C, PCI Express | COM-2C-LPE CONTEC

The new products are low-profile, RS-232C serial communication boards compliant with PCI Express. The board can expand asynchronous RS-232C serial communication ports on a PC with a PCI Express compliant slot. The board is available in three models different in the number of on-board RS-232C serial communication ports: 1-channel type "COM-1C-LPE", 2-channel type "COM-2C-LPE", and 4-channel type "COM-4C-LPE".

The three new models support high-speed communication at up to 921,600 bps. The bundled driver software can be used for Windows and Linux to recognize the on-board ports as OS's standard COM ports, allowing them to be set as COM1 to COM256. The board has high-capacity FIFO buffer memory: 128-byte transmit buffer and 128-byte receive buffer. The FIFO buffer memory can be adjusted in buffer size for starting data transmission/reception. You can optimize the buffer size for each application, for example by increasing the buffer size to reduce the CPU load or decreasing it to improve realtimeness.
