1Ch Isolated RS-422A/485 Serial I/O for PC-Card

COM-1D(PM) is the PC card of the PC Card Standard conformity which expands RS-422A / 485 serial communication port of one channel in a personal computer. UART 16550 which has the FIFO buffer of 16 bytes of transmission / 16 bytes of reception in each channel is carried. It can be used as a Windows or standard COM port for Linux. A program is also possible at a Win32 API communication function or MSComm.

	Since Plug&Play correspondence is carried out, the resource information on an I/O Address or IRQ is set up automatically.
	The baud rate of each channel can be set up by software.
	The FIFO buffer of 16 bytes of transmission and 16 bytes of reception is carried.
	The 100ohm terminator (terminus resistance) required at the time of party line (multi-drops) connection is built in, and it can insert in each signal line by changing a switch.
	All RS-422A / 485 signal lines are isolated electrically.
	It can be used as Windows and a standard COM port of Linux by attached driver software. Programming in communication control (MSComm) of Win32API communication functions (CreateFile( ) and WriteFile( ) etc.) or Visual Basic is also pos
