Advantech PCM-3612I Startup Manual

PCM-3612I
4-port RS-232/422/485 PCI-104 Module
Introduction
The PCM-3612I is a PCI-104-compatible 4-port
RS-232/422/485 serial interface module. It works
with PCI-104 CPU modules or CPU cards which
accept PCI-104 expansion modules. It provides four
independent serial interfaces,accessed through the
IDE 40-pin connector(s). 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(PCM-3612I) port address
Initial Inspection
We carefully inspected the PCM-3612I 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.
