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.

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.

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 vector address determines the address for each of the
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.

(M1, JP3, JP4, JP6, JP7)
The card’s IRQ can be set using M1 of SW1. Please note that
the DIP switch is for setting the mode as shown below.
Shared IRQ Mode
Independent IRQ Mode
Independent IRQ (JP1-JP4)
In this mode, each of the four ports can have IRQ channels
set individually. For each port, select an IRQ not in use by
other devices in the system. The map of jumpers and ports is
shown below.
Port 1 —> JP3
Port 2 —> JP4
Port 3 —> JP5
Port 4 —> JP6
Shared IRQ (JP3)
Select an IRQ which is not in use by another card in the sys-
tem. If you are installing more than one PCM-3614, set them
to different IRQ numbers. Jumper Bank JP3 controls the card
IRQ. Please refer to the following figure for example.
Interrupt Status Register Setup (SW1,Vector
address)
The feature on the PCM-3614 is utilized in the shared IRQ
mode. When data arrives at any one of the four ports, an in-
terrupt will be generated in the interrupt register.The PC soft-
ware can read this, and identify immediately which port gen-
erated the interrupt.This saves time and makes programming
easier.When a data bit of the interrupt status register is set to
0, the corresponding channel is selected to generate an in-
terrupt. If the bit is 1, then no interrupt is generated. The DIP
switch, SW1, controls the card’s interrupt status register, as
shown in the following figure and table.
Interrupt Status Register SW1
Bit Function
0 Port 1
1 Port 2
2 Port 3
3 Port 4
4 Not Used
5 Not Used
6 Not Used
7 Not Used
The user may change the interrupt status address via SW1.
Please note that the address decoder will occupy a continu-
ous, 16-byte area, according to the switch setting. For exam-
ple, if you set the switch to 210H, then the address 210H to
21FH will be decoded.The various DIP switch settings (SW1)
for the interrupt status register are shown in the table below.

Speed Mode Selection
The PCM-3641 employs a unique speed option that allows
the user to choose either normal speed mode (1x) or high
speed mode (8x).This high speed mode is selected at SPEED
of SW2.
Normal Speed Mode
To select the baud rate commonly associated with COM ports
, such as 2400, 4800, 9600. . .115.2 Kbps, place the switch
as follows.
High Speed Mode
To increase normal mode rates up to eight times, (e.g.if 115.2
Kbps is selected, the rate can be increased up to 921.6 Kbps),
place the switches as follows.
Operating Environment Selection
Set jumper 8 (JP8) to correspond with your desired software
operating environment. Connect the left two pins of JP8 to
operate in DOS or Windows 3.1 mode, as shown below. Con-
nect the right two pins to operate inWindows 95/98/NT mode.
DOS and Windows3.1 Windows 95/98/NT
Driver Installation for DOS Users
Make a duplicate copy of the driver diskette in case the orig-
inal disk becomes lost or damaged. Copy the files to a subdi-
rectory on your hard disk if you wish.
Card setup
The PCM-3614’s driver determines the configuration of the
installed cards by reading a data file, GEN-DRV.CNF. When
you first install the PCM-3614, and each time you change the
card’s address and IRQ, you will need to run the card setup
program to save the settings to the configuration file. Pro-
gram files should be installed to the hard disk.Insert the driv-
er disk in your computer, type DOSINST from the prompt and
press enter. Once the files have been installed, type SETUP
from the \COMLIB\BIN prompt and press ENTER. After the
screen shows up, move the cursor bar (using the arrow keys
or the mouse) to the general serial board field and press
ENTER. The screen shown below will appear.
When you finish setting up the ports, press the ESC key to
return to the previous windows. Press F10 to save the new
configuration or ESC to quit without saving. The setup pro-
gram will then create a new configuration data file GEN-
DRV.CNF.
It is a simple example program capable of sending and re-
ceiving data after each port is opened with selected commu-
nication parameters. As Windows 3.x features multitasking,
multiple windows for the ports can appear simultaneously
under TTY. However, Terminal, the application provided by
Windows is limited for the use of COM1 to COM4.
After completing the installation, restart Windows. And addi-
tional line “comm.drv = sercomm.drv”, will appear for the PCM-
3614 in the [boot] section of the Windows SYSTEM.INI file. In
addition, a Windows group “PC-ComLIB Standard COMM
Driver”will be generated for reconfiguration, driver removal,
etc. At this point, you are ready to execute applications that
support Windows COMM API calls.
