INTRODUCTION
The new FASTCOM: 422/4-104-ET adapter is the fastest (1.5 Mbps), most advanced, four-port RS-422
asynchronous adapter in the industry. Primarily designed for commercial, industrial, and OEM applications, the
FASTCOM: 422/4-104-ET features four discrete RS-422 channels, complete with RTS and CTS flow control
signals, and is specified to operate in the extended temperature range.
The advanced UART on the FASTCOM: 422/4-104-ET features full compatibility with standard 16C550 and
16C650 UARTs, but provides extraordinary 128-byte receive and transmit FIFOs for buffering. This buffering
is extremely important when working with RS-422/RS-485 communications within high overhead operating
systems such as Windows NT and Windows 95/98. The extra-deep FIFOs prevent data loss due to overrun and
dramatically improve data throughput in all applications. The advanced UART on the FASTCOM: 422/4-104-ET
is capable of all standard baud rates plus a high-speed mode capable of up to an amazing 1.5 Mbps
(crystal change required).
The Fastcom CD contains software and information for DOS, Linux, Windows 95/98, Windows NT, and Windows
2000, and is compatible with Windows XP. The "shared interrupt" design and user selectable address allow the
installation of multiple FASTCOM: 422/4-104-ET cards in the same system.
The FASTCOM: 422 family of adapters includes the dual channel FASTCOM: 422/2-104, the single channel
FASTCOM: 422/1-ISA and the dual channel FASTCOM: 422/2-ISA for the ISA bus, and the fully isolated
FASTCOM: IG422/1-ISA. The FASTCOM: 422/2-PCI, the FASTCOM: 422/4-PCI, and the FASTCOM: IG422/1PCI are available for PCI bus systems.

INSTALLING THE FASTCOM: 422/4-104-ET IN THE PC/104 STACK
1.
Unpack the FASTCOM: 422/4-104-ET. Keep the box and static bag for warranty repair returns.
2.
Check the switches to be sure that they are set for the mode you want.
3.
Re-install the cover on your PC/104 stack.

TESTING THE INSTALLATION
To fully test the installation of your FASTCOM: 422/4-104-ET, you will need to build a “loop back plug”. Materials
needed are a DB9 male plug, solder cup style, and a few short pieces of 20 or 24 AWG stranded wire. Jumper
the pins together on the DB9 as illustrated below:

TESTING YOUR FASTCOM ASYNC PC/104 PORT IN WINDOWS
These instructions assume that you have already installed the card and have followed the installation instructions.
In NT, the ports should be visible in the Control Panel ->Ports applet. In Windows 98, the ports should show up in
Control Panel in the System icon’s Device Manager. The port installation instructions can be found on the disk in:
For Windows98
D:\Fastcom_Disks\Smart14\Windows\W98\howto.txt
For Windows NT
D:\Fastcom_Disks\Smart14\Windows\NT\howto.txt
For Windows 2000/XP D:\Fastcom_disks\Smart14\WINDOWS\W2000\W2kserialInstall.txt
For Linux
D:\Fastcom_disks\Smart14\howto.txt
1. Install the loopback plug on the port to test.
2. Find and run the TTY.EXE program.
From the Start menu, choose Run, browse to and select
D:\Fastcom_Disks\Smart14\windows\win32\tty\tty.exe.
Select TTY.EXE and click open.
Click OK to run the TTY program.
3. From the menu bar on the TTY program, select Settings.
Select the port to test (e.g., COM5)
Uncheck all of the flow checkboxes (DTR/DSR, RTS/CTS, XON/XOFF).
Click OK.
4. From the TTY main menu bar select Action, then Connect.
5. At this point you should see a blinking cursor in the upper left corner of the TTY window. Try to type on the
keyboard; you should see the characters that you are typing in the TTY window. If you see what you type, the
port is passing the loopback, and is installed and functioning correctly.
If you get a “Connection Failed” message box when you try the Action ->Connect sequence, some possible
causes are:
1. Incorrect or mismatched address or IRQ settings between what the switches on the board are set to and
what is set up in the driver. You can check the driver settings in NT using Control Panel ->Ports ->COMx
->Advanced. In Windows 98, you need to look in Control Panel ->System, Device Manager tab, Ports
(COM & LPT), select the COM#, click the Properties button, then the Resources tab. Check the address
switch settings using the table in the back of the manual. Realize that multiport cards addresses are
6
sequential (if set to base address of 0x280, then the addresses for the four ports will be 0x280, 0x288,
0x290, and 0x298).
If you are using NT, you can run NT Diagnostics (from the Start button, choose Programs >Administrative Tools ->Windows NT Diagnostics) to verify that there is not another device trying to use
the address range or IRQ. The Resources tab in Windows 95 (location listed above) should indicate a
resource conflict if another device is using the same I/O range or IRQ. Even if you don’t see a listed
conflict, try a different address/IRQ combination if all of the settings are matched and it still doesn’t work.
If you have tried a couple of different address/IRQ combinations without success, you might try using an
Ohm meter or continuity tester to verify that the switch positions are actually what they are set to. The
switch positions that are ON should be closed (about 0 ohms); the ones that are OFF should be open (not
0 Ohms). Sometimes the dip switches will get stuck in either the on or off position irrespective of the
position of the slide. If this happens, try toggling the stuck position on and off a few times and re-check it.
2. In NT, if multiple ports are opened (running more than one instance of TTY), the ports are using the same
IRQ, and the PermitShare registry entry is 0, the second port to be opened will fail. Use the registry
editor and expand HKEY_LOCAL_MACHINE ->SYSTEM ->CurrentControlSet ->Services ->Serial,
change the PermitShare value from 0 to 1, reboot, and run the test again.
If you get to the blinking cursor stage, but do not see what you type with the loopback plug installed, some
possible reasons are:
1. Incorrect/faulty loopback plug construction or a bad connection.
2. If you have a RS-422/485 board, check to make sure that the 485 mode is disabled. The loopback test
should be run in RS-422 mode (the RS-485 driver control switches should be in the OFF position).
3. The RTS/CTS flow control is checked and there is not a RTS->CTS loopback, or the CTS disabled switch
is OFF. If you enable flow control, you must allow CTS to be active in order for the driver to transmit data.
Either disable flow control, or wire the RTS->CTS (and possibly DTR->DSR) loop and try the test again.
4. Check to make sure that the loopback plug is on the correct port/cable (or that the correct port is selected
in the settings dialog).
5. If you type a character and the cursor stops blinking for a long time and the PC/TTY window stops
responding (appears locked up) but returns to a blinking cursor state after a few minutes, this is a good
indication that the interrupt setting on the card is not the same as the interrupt setting of the port in
Windows. Re-verify that the IRQ setting on the board switches and in Control Panel are the same.

SWITCH DESCRIPTIONS
There are four dip switches on the FASTCOM: 422/4-104-ET, labeled SW1 through SW4 (See Board Layout
Illustration for location). Switch 1 (labeled BASE ADDRESS) is used to set the base I/O address of the
FASTCOM: 422/4-104-ET board. Switches 2 and 3 (labeled IRQ SELECT) serve two functions: they select the
IRQ level and are used to enable/disable interrupt sharing. Switch 4 (labeled MODE SWITCH) selects either RS422 or RS-485 mode and enables/disables handshaking for each channel.
SWITCH 1, BASE ADDRESS
Switch 1 decodes the PC/104 address lines as follows:
ON
1 2
3 4

A9

A8
A7
100
A6
A5
40
20
A4
A3

80
Address lines A5 through A12 are decoded by the setting of SW1
and set the address of each channel of the FASTCOM: 422/4-104ET. Address lines A3 and A4 are used on the board to select
which port (1, 2, 3, or 4) you want to use. Address lines A0, A1,
and A2 are used to select the registers within the UARTs.
The above diagram illustrates a base address of 280 Hex. Note
that when a switch is ON it represents a “0” in the corresponding
bit position (not a “1” as you might expect). Also, a switch that is
OFF represents a “1” in the corresponding bit position. If you
would like to know why this is reversed, read a technical data
sheet for the address decoder chip, a 74LS682.
8
So, the SW1 diagram can be decoded as follows:
A12
0
A11
0
A10
0
A9
1
A8
0
A7
1
A6
0
A5
0
You can determine the base I/O address of the board by adding the Hex values for each address line that is set to
a “1”. In the illustration, address lines A7 and A9 are set to “1”. So, add the hex value of A9 (200H) and A7
(80H), and the result is the base I/O address (200H + 80H = 280H).
Switch 1 is referred to as the Base Address switch because it marks the beginning address of the first channel on
the FASTCOM: 422/4-104-ET board. The other channels are addressed as an offset to the first channel. For
example, if we set the Base Address to 280H, note the address of each channel:

We have provided a comprehensive guide to setting the address switch in
Appendix A.
Please note that not all of the I/O address space in a PC/104 stack is available for your use. If you wish to select
an address other than the default, refer to Appendix A, I/O Address Usage Table, and select an address that does
not conflict with devices installed in your PC/104. Keep in mind that the FASTCOM: 422/4-104-ET requires 8
contiguous bytes of address space per channel, for a total of 32 contiguous bytes.
8
If you want to install more than one FASTCOM: 422/4-104-ET board in your computer, be sure to set each to a
unique I/O address. We recommend the following addresses for a multi-board system:
BASE ADDRESS
FASTCOM: 422/4-104-ET BOARD 1
FASTCOM: 422/4-104-ET BOARD 2
FASTCOM: 422/4-104-ET BOARD 3
FASTCOM: 422/4-104-ET BOARD 4
280H
300H
380H
400H
Remember that a single IRQ level can be shared between multiple FASTCOM: 422/4-104-ET boards in a PC/104
stack.
SWITCHES 2 and 3, INTERRUPT SELECT
Switch 2 serves three functions: it selects the IRQ level for the FASTCOM: 422/4-104-ET, enables/disables
interrupt sharing, and selects the operating mode for the board. Switch 3 selects upper level IRQ settings.
The following illustrates the IRQ select switches on the FASTCOM: 422/4-104-ET:

You can use any IRQ that is not assigned to a device installed in your PC/104.
INTERRUPT SHARING
An important feature of the FASTCOM: 422/4-104-ET is its ability to share one IRQ with several other FASTCOM
boards in the same computer. This is important because there are very few unassigned IRQs in the PC/104.
9
Switch 2 positions 1 and 8 control the interrupt sharing circuit on the FASTCOM: 422/4-104-ET. Position 1
Enables interrupt sharing in the OFF position and Disables sharing in the ON position. Position 8 is called the
“Board 1” switch. In the interrupt sharing mode, this switch must be ON for the first FASTCOM: 422/4-104-ET
board in your system, and OFF for all other FASTCOM: 422/4-104-ET boards.

For example, let’s assume that you want to set two FASTCOM: 422/4-104-ET boards to share IRQ 5. Set

For any additional FASTCOM: 422/4-104-ET board that shares IRQ 5, set Switches 2 and 3 the same as the first
board.
SWITCH 4, OPERATING MODE
The FASTCOM: 422/4-104-ET has two modes of operation selected by Switch 4: the RS-422 mode and the RS485 mode.

Channel 4 CTS handshaking
Channel 3 CTS handshaking
Channel 2 CTS handshaking
Channel 1 CTS handshaking
Switch positions 1, 2, 3, and 4 enable or disable CTS handshaking for each channel. When ON, CTS
handshaking is disabled; when OFF, CTS handshaking is enabled. In RS-485 mode, CTS handshaking is usually
disabled.
10
Switch positions 5, 6, 7, and 8 enable or disable RS-485 driver control for each channel. When ON, the transmit
driver enable line is controlled by the state of the RTS line of the UART. The RTS line may be controlled directly
by your software by writing to the UART Modem Control Register (See Appendix B). Setting the RTS bit to 1 in
the Modem Control Register will enable the drivers; setting it to 0 will disable the drivers.
11
RS-422/RS485
Most engineers have worked with RS-232 devices at least once in their career. If you have never worked with
RS-422 or RS-485 devices, you will be pleased to know that working with the FASTCOM: 422/4-104-ET is not
much different from working with an RS-232 device.
The RS-422 standard was developed to correct some of the deficiencies of RS-232. In commercial and industrial
applications, RS-232 has some significant problems. First, the cable length between RS-232 devices must be
short (usually less than 50 feet at 9600 Baud). Second, many RS-232 errors are the result of cables picking up
normal industrial electrical noises, such as fluorescent lights, motors, transformers, and other EMF sources.
Third, RS-232 data rates are functionally limited to 19.2K Baud. On the other hand, the newer RS-422 standard
makes cable lengths up to 5000 feet possible and is highly immune to most industrial noises. Data rates are also
improved - the FASTCOM: 422/4-104-ET features data rates up to 1 Meg Baud. These improvements were
made possible by differentially driving and receiving the data as opposed to the single ended method employed
by the RS-232 standard. With the RS-422 standard, the transmit signal (TX in RS-232) is a differential signal
consisting of TX+ and TX-, the receive signal (RX in RS-232) consists of RX+ and RX-.
Another drawback of RS-232 is that more than two devices cannot share a single cable. This is also true of
RS-422, and that’s why the RS-485 standard was developed. RS-485 offers all of the benefits of RS-422 and
also allows multiple units (up to 32) to share the same twisted pair. RS-485 is often referred to as a “multi-drop”
or “two-wire, half duplex” network because the drivers (transmitters) and receivers share the same two lines. In
fact, up to 32 stations can share the same “twisted pair”. In order for an RS-485 system to work, only one driver
(transmitter) can occupy the network at a time. This means that each station on the network must control the
enabling/disabling of its drivers in order to avoid network conflicts. If two drivers engage the network at the same
time, data from both will be corrupted. In RS-485 mode, the receivers are always enabled.

12
TERMINATION RESISTANCE
In both the RS-422 and the RS-485 mode, the receiver end of the cable between two stations must be terminated
with a resistor equal to the characteristic impedance of the wire. This is to prevent signal reflections in the wire
and to improve noise rejection. However, you do not need to add a terminator resistor to your cables when
you use the FASTCOM: 422/4-104-ET. The termination resistance is built in. We have installed a terminator
resistor for each receiver: between each RX+ and RX-, and between CTS+ and CTS- for each channel.
If you are using the FASTCOM: 422/4-104-ET in a multi-drop network, the termination resistor should be removed
from all units except the first and last (see the RS-485 illustration below). Call for technical support if you need to
modify the resistor.
Observe the resistors in the following illustration and remember that they are built into the FASTCOM: 422/4-104ET:
