Four RS-232C serial ports on a single low-profile PCI board. The COM-4(LPCI)H supports baud rates up to 921,600 bps, with 128-byte FIFO buffers per channel. Use as standard Windows/Linux COM ports with full hardware handshake control. Includes both low-profile and standard brackets.
The COM-4(LPCI)H provides four RS-232C-standard serial ports on a single low-profile PCI board. Each channel supports baud rates from 30 to 921,600 bps, with independent 128-byte FIFO buffers for transmit and receive. The control lines (RTS, CTS, DTR, DSR) can be fully controlled and monitored via software.
Standard COM port compatibility — With the COM-DRV driver, the COM-4(LPCI)H can be used exactly like the built-in COM ports of a PC, supporting Win32 API DCB structures and Linux-standard system calls.
Designed for industrial and embedded applications, the COM-4(LPCI)H offers flexible mounting options and high-speed communication with low CPU load.
