Description
The PCL-749 series offers general purpose multi-serial I/O boards
for PC/AT and compatible systems. Each board provides 4 RS-232
communication channels which allows connection to serial devices
such as modems, terminals, printers, data collection instruments, etc.
The boards in this series are equipped with a state-of-the-art ASIC
chip. This newly designed chip is capable of accommodating all of
the circuitry commonly used by multiport boards. The number of ICs
is decreased, allowing for a compact half-size board.
The switchless and jumperless design allows the PCL-749 to be
easily configured via software. To meet the next generation require-
ment of high-speed transmission, 16C550 FIFO UARTs are used.
16C550 UART features built-in 16 bytes FIFO to prevent data loss
even at transfer rates of 115.2 Kbps. Space is reserved for optional
surge protection on all port lines to prevent damage from electrical
shock.
The PCL-749 series is so flexible in configuration that compatibility
with virtually all other manufacturer's 4-port multi-serial boards is
maintained. Additionally, it is suitable for use under most operating
systems including Windows NT, Windows 95, OS/2, Windows 3.x,
DOS, SCO UNIX/XENIX, Linux, QNX, PICK OS, MUMPS, and
IMS Multiuser DOS, etc.
