PCM-3614I
4-port RS-232/422/485 Module
The PCM-3614I is a PCI-104 compatible module
with 4 individually configurable RS-232/422/485
ports. The PCM-3614I also features high
transmission speeds, independent/shared IRQ’s, a
high-performance 16C550 UART communication
chip with 16-byte FIFO to reduce CPU load, and
more. These function settings include Standard/
Enhance, Independent/Shared IRQ & Speed modes.
We carefully inspected the PCM-3614I 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.

Card Configuration
The max configuration for the PCI bus of PCI-104
modules is FOUR plus the host board. If you stack
more than one PCI-104 module to a host board be
sure to set the modules to different PCI numbers
through SW2.
SW1 Settings
1. Use pin 5 ~ 8 on SW1 to determine mode of
port 0 to port 3 as RS-422 or RS-485. The pin
number and port number are mapping directly.
• “ON” is RS-485 mode. “OFF” is RS-422 mode.
• For example, pin 5 is mapping to port 0. So if
you set pin 5 to “ON”, it means port 0 is RS-
485 mode.
• If you set pin 5 to “OFF”, it means port 0
becomes RS-422 mode.
