PCM-3641P
4-port RS-232 High-Speed Module
The PCM-3641P is a PC/104+-compatible 4-port
RS-232 serial interface module. It works with PC/
104+ CPU modules or CPU cards which accept PC/
104+ expansion modules. It provides four
independent serial interfaces, accessed through an
IDC 40-pin connector. The module’s industry-
standard 16C550 asynchronous communication chip
is fully programmable. The module requires no
special commands or control codes if you use the
standard COM1 ~ COM4 port addresses.
We carefully inspected the PCM-3641P both
mechanically and electrically before we shipped it.
It should be free of marks and scratches and in per-
fect electrical order on receipt.
Handle the board only by its edges. The static
charge on your body may damage its integrated cir-
cuits. Keep the card in its anti-static package when-
ever it is not installed. You can use this package to
return the card if it should need repair.
