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-
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.

Card Configuration
Each port on the PCM-3614 card requires configuration prior
to use. The DIP switches set ports to the appropriate I/O ad-
dress (SW2) and different modes (SW1). The jumpers set the
port's IRQ.
Default Settings
The board is shipped with default settings. If you need to
change these settings, however, see the following sections.
Otherwise, you can simply install the card.
PCM-3614 Default Configuration
Setting Default Function

Speed Mode 1 x
IRQ mode Share
Base Address Address 300H
Vector Address Interrupt 280H
Standard/ Enhanced Enhance
Operating System Windows 95/98/NT
Jumper and switch settings
The PCM-3614 can function in many different modes accord-
ing to your application needs. These modes include Standard/
Enhanced Mode, Independent/Shared IRQ Mode, Speed
Mode, and Operating System Mode. Details of these specific
modes are described as follows:
Standard/Enhanced Mode (M0)
PCM-3614 can be used in standard or enhanced mode. In
standard mode the I/O addresses are compatible with the
standard PC communication ports, COM1 ~ COM4. In en-
hanced mode you can select a different base address. The
offset of each port from the base address is fixed. You can
use M0 of DIP switch (SW1) to select standard or enhanced
mode.
In the following sections, we will use the icons shown below
to represent switches set for ON or OFF.
Standard mode
In standard mode, the I/O address of the ports are as follows:
Port I/O address Interrupt No.
Port 1 3F8 Selectable
Port 2 2F8 Selectable
Port 3 3E8 Selectable
Port 4 2E8 Selectable
Enhanced mode
In enhanced mode, you can select a different base address.
The address dete mines the address or each of thebase r f
four ports.
The I/O addresses for the four ports are as follows:
Port I/O address
Port 1 Base + 00H
Port 2 Base + 08H
Port 3 Base + 10H
Port 4 Base + 18H
You use switches 1~7 of DIP switch SW2 to set the base
address anywhere from hex 200 to 3F8.
To set the base address, you have to calculate the base
address as follows: (switch ON is “0”, switch OFF is “1”.)
The following table shows different base address settings.
Port base address (SW2)
Base Address A3 A4 A5 A6 A7 A8 A9
200 - 207 (hex) llllll¡
208 - 20F (hex) ¡lllll¡
*300 - 307 (hex) lllll¡¡
3E8 - 3EF (hex) ¡l ¡¡¡¡¡
3F8 - 3FF (hex) ¡¡¡¡¡¡¡
l ¡: ON : OFF * : Default
Note: If your CPU module or card has serial interface ports,
you will need to adjust the I/O port addresses (or dis-
able the ports) to avoid conflicts.
Switch is set ON.
Switch is set OFF.
