PCM-3614
4-port RS-422/485 High-Speed Module
Introduction
The PCM-3614 is a PC/104-compatible module with four in-
dividually configurable RS-422/485 ports. It works with PC/
104 CPU modules to extend additional RS-422/485 ports. The
PCM-3614 also features lots of functions such as high trans-
mission speed 921.6 kbps, independent/shared IRQ and more.
It also provides high-performance 16C550 UART communi-
cation chip with 16-byte FIFO to reduce CPU load. This makes
the PCM-3614 especially suitable for multitasking environ-
ments.
The PCM-3614 comes with a Windows 95/98/NT/ME con-
figuration utility (Windows 2000/XP utility will soon be ready
and allowed to download through our Web site). The Win-
dows configuration utility provides functions such as self-di-
agnostics and performance analysis for easy troubleshooting
and debugging.
The PCM-3614 provides versatile function settings to meet
users' needs. These function settings include Standard/En-
hance mode, Independent/Shared IRQ mode and Speed
mode. Standard/Enhance mode setting helps the user use
base address more flexible. Especially in Enhance mode, dif-
ferent base addresses can be set according to the applica-
tion. In Shared IRQ mode, all ports of interrupt can be speci-
fied to one. This solves the problem of IRQ insufficiency within
the embedded system. In Speed mode, the PCM-3614 al-
lows transmission rate up to 921.6 kbps, improving the over-
all performance of the system.

Initial inspection
We carefully inspected the PCM-3614 both mechani-
cally and electrically before we shipped it. It should
be free of marks and scratches and in perfect elec-
trical order on receipt.
Handle the board only by its edges. The static change
on your body may damage its integrated circuits.
Keep the card in its anti-static package whenever it
is not installed. You can use this package to return
the card if it should need repair.

Page 2: Card Configuration
To set the base address, you have to calculate the base Standard/Enhanced Mode (M0) address as follows: (switch ON is “0”, switch OFF is “1”.) PCM-3614 can be used in standard or enhanced mode. In Base address Decimal standard mode the I/O addresses are compatible with the... - Page 3 Shared IRQ (JP3) 090H 0A0H Select an IRQ which is not in use by another card in the sys- tem.

When 390H you first install the PCM-3614, and each time you change the 3A0H card’s address and IRQ, you will need to run the card setup program to save the settings to the configuration file. Pro- 3B0H gram files should be installed to the hard disk.
