INTRODUCTION
The Fastcom: IG232/2-PCI adapter is one of the fastest, most advanced two-channel RS-232 adapter in the
industry. Primarily designed for commercial, industrial, and OEM applications, the Fastcom: IG232/2-PCI
features two discrete RS-232 channels, which are electrically isolated from your computer’s power supply
and bus.
The advanced universal asynchronous receiver and transmitter (UART) chips used on the Fastcom: IG232/2-PCI
are fully register compatible with standard 16C550 UARTs, but provide extraordinary 128 byte FIFOs for
receive and transmit buffering. This buffering is extremely valuable when working with RS-232
communications within high-overhead operating systems such as Windows NT and Windows 95/98.
Most RS-232 adapters that advertise isolation provide only partial isolation for the signal lines. The full isolation of
RS-232 signal lines and Ground provided by the Fastcom: IG232/2-PCI is extremely important to any
industrial/commercial application that requires high reliability, data integrity, and system safety. Power surges
and ground loop errors will destroy common RS-232 adapters. More importantly, these conditions will destroy
your PC, adapters in it, hard and floppy disk drives, and present an electric shock hazard to system operators.
The Fastcom: IG232/2-PCI is designed to provide full isolation from a remote RS-232 device: the UARTs are
isolated from the RS-232 signals, the Ground is isolated from the power supply and chassis of the PC, and each
channel is fully isolated from the other.
Software drivers for Windows 98/NT/2000/XP and Linux are supplied. Multiple Fastcom: IG232/2-PCI adapters
can be installed in all operating systems.
The Fastcom RS-232-PCI family also includes the four-channel Fastcom: 232/4-PCI and the eight-channel
Fastcom: 232/8-PCI. ISA bus versions are also available. If your application requires faster data rates or better
noise immunity, we suggest you try our RS-422 family of PCI adapters, such as the Fastcom: IG422/1-PCI.

HARDWARE INSTALLATION
Important: Observe Electrostatic Discharge (ESD) precautions when handling the Fastcom: IG232/2-PCI
board.
1. Unpack the Fastcom: IG232/2-PCI. Keep the box and static bag for warranty repair returns.
2. Select an open PCI slot in your PC.
3. After removing the blank bracket from your PC, install the Fastcom: IG232/2-PCI in the PC by pressing it
firmly into the slot. Install the bracket screw to hold it firmly in place.
4. Re-install the cover on your PC.
SOFTWARE INSTALLATION
Select the link above to open the Installation Manual. Under Fastcom – Async-PCI series cards, select your
operating system and follow the instructions. When you are finished, select Fastcom: IG232/2-PCI from the list at
the end of the Fastcom – Async-PCI series cards section to return to this manual.
TESTING THE INSTALLATION
To fully test the installation of your Fastcom: IG232/2-PCI, you will need to build a "loop back plug". Materials
needed are a DB25 female receptacle, solder cup style, and a few short pieces of 20 or 24 AWG stranded wire.
This loop back plug can be used to test any RS-232 port. Jumper the pins together on the DB25 as illustrated
below:

TESTING YOUR FASTCOM ASYNC PCI PORT IN WINDOWS
These instructions assume that you have already installed the card and have followed the installation instructions.
The SERIALGT.EXE program (98, NT) or the Device Manager (2K, XP) should show the boards/ports that are
installed, and the COM numbers assigned to those ports.
1. Attach the “octopus” cable supplied to the DB37 connector. Install the loopback plug on the port to test.

2. Find and run the TTY example program (simple terminal).
From the Start menu, choose Run, browse to and select D:\Fastcom_disks\AsyncPCI\tty\tty2.exe.
Click the Open button.
Click the OK button to run the program.
3. With the TTY program running, select Settings from the menu.
Select the COM port number that has the loopback plug on it.
Uncheck all of the flow control checkboxes (DTR/DSR, RTS/CTS, XON/XOFF).
Click OK.
From the TTY Main menu select Action, then Connect.
4. At this point you should get a blinking cursor in the upper left corner (under the menu bar).
5. You should be able to type on the keyboard and see the letters that you type on the screen. If you see what
you are typing, then your port is installed and operating properly.
If you do not get to the blinking cursor stage, but rather encounter a “Connection Failed” message box, some
possible causes are:
1. 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.
2. The interrupt that was selected by the plug-and-play bios is trying to be shared with another device that is
not configured to share the IRQ (either Device or Driver Exclusive IRQ setting). Try a different PCI slot or
disable the other offending device.
3. IRQ steering is enabled on Windows 98 and Windows is not assigning an IRQ to the Fastcom card. Try
disabling IRQ steering or varying the options in Control Panel ->System ->Device Manager ->System
Devices ->PCI Bus.
4. Multiple COMx assignments. In Windows NT, the driver setup assumes that there are not any ports
installed above COM4, and starts assigning the Fastcom ports at COM5. If there is already a COM5 (or
higher) in the system, it is likely that the Fastcom ports are being assigned to the same port name(s).
Run the SERIALGT.EXE program (D:\Fastcom_disks\AsyncPCI\nt\serialgt.exe for Windows NT,
D:\Fastcom_disks\AsyncPCI\95\serialgt.exe for Windows95) and re-assign the com port numbers to these
ports to be different than any other ports in the system.
If you get to the blinking cursor stage, but do not see what you type with the loopback installed, some possible
reasons are:
1. Incorrect/faulty loopback construction or a bad connection.
2. The port is setup to have RS-485 enabled and the “RX Echo Disable” checkbox is checked. If the RX
Echo Disable is checked you will be unable to run a simple loopback test, as the purpose of the echo
disable is to strip the characters that are sent/received at the same time. Uncheck the RX Echo disable,
reboot, and try the test again.
3. The RTS/CTS flow control is checked and there is not a RTS->CTS loopback or the CTS disabled
checkbox was unchecked. 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) loops
and try the test again.
4. The loopback plug is not on the correct port/cable.

FASTCOM SERIAL SETTINGS
These settings can be accessed using the application serialgt.exe (Windows 98/NT) or in the Fastcom Serial Settings tab of
the Fastcom AsyncPCI Communications Port Properties dialog (Windows 2K/XP), which is found in the device manager under
Ports (COM & LPT).
CLOCK/4
Clock divisors of 1 and 4 are available. Clearing the checkbox selects a divisor of 1 and setting the checkbox
selects a divisor of 4. It is best to leave this box unchecked.
RX Trigger
Determines the number of bytes that will be stored in the receive FIFO on the 16C854 before an interrupt is
triggered. Valid values are from 1 to 128 bytes. The optimal setting is 64 bytes. For 16C550 compatibility,
set to 8.
TX Trigger
Determines the number of bytes remaining in the transmit FIFO on the 16C854 before an interrupt is
triggered. Valid values are from 0 to 127 bytes. The optimal setting is 64 bytes. For 16C550 compatibility,
set to 0.
TX Write Size
Determines the number of bytes sent to the board at a time. Valid values are from 1 to 128. This number
plus the TX Trigger value should not exceed 128. The optimal value is 64. For 16C550 compatibility, set to
16 or 1.
BaudTable (Win2K/XP)
This table represents the standard baud rates that the Fastcom card will currently support. If you wish to use
a non-standard baud, you may enter it into one of the boxes on the table and hit the tab key (do not hit enter,
hitting enter will exit the program). This will set the on-board clock generator to a frequency (see Input
Frequency below) that will divide down to the new baud rate. The rest of the table will also be updated to
reflect other bauds that can be used with the calculated clock frequency. If you wish to return to the standard
rates, you can set the top box to 115200 and hit tab; the rest of the bauds will be filled in.
Note: The baud rates that you set will not be available to standard Windows applications like HyperTerminal.
The new rates will be available to you in your code or in applications that allow user defined baud rates such
as TTY2, which can be found on the Fastcom disk (Fastcom_CD\Fastcom_disks\AsyncPCI\tty\tty2.exe).
THIS SETTING=THIS BITRATE (Baud Rate Substitution Table) (Win98/NT)
Under THIS SETTING you will see the standard PC baud rates, from 115.2K to 300. If you wish to use a
baud rate not shown, type the baud rate in the box next to 115200 (e.g., type 128K as 128000), and hit the
tab key. Do not hit enter. Hitting enter will exit the program. If the baud rate changes after you tab, move to
the next box down and try again. Continue moving down until the baud rate stays the way you want it. Now
note the standard PC baud rate to the left of the box you ended on. You will select this standard baud rate to
set up your com ports, and the baud rate you require will be substituted. If you receive an error message
stating that the maximum baud rate was exceeded, change the Clock Divisor to 1 and try again.
INPUT FREQUENCY
This is the calculated frequency required to generate the baud rate requested. When you click OK on the
Fastcom Serial Settings page, this frequency is sent to the clock generator and the new baud rates will be
available.
OTHERS
Auto 485, CTS Disable, 485 Enable, RX Echo Disable, Enable Source, and Sample Rate do not apply to this
board. Do not change these options as they will have no positive affect on settings for this board and may
cause instability.

CABLE
We recommend using a high quality vinyl jacketed multiple conductor cable like Belden 8445 (unshielded) or
Belden 9941 (shielded) for use with the FASTCOM: IG232/2-PCI. VERY IMPORTANT: The signal ground (pin 5
on the DB9 connector) is isolated from the ground on your computer, but the outside shell of the DB9 connectors
on the IG232/2-PCI are in direct contact with the chassis case of the computer. Many PC style computers ground
the case of the computer.
To avoid defeating the isolating functions of the IG232/2-PCI, do not
connect the shield of a cable to the outside shell of the DB9 connectors.
If you want to build a shielded cable, connect the braided shield of the wire to only one end of the cable only; keep
the other end of the cable insulated from the shield.
DB9 PIN DESCRIPTION
The FASTCOM: IG232/2-PCI features two RS-232 channels which are accessed through two male DB9
connectors on the board.
The following is a pin description of the DB9 connectors:
PIN SIGNAL NAME DIRECTION
1 NOT CONNECTED
2 RECEIVE DATA (RXD) INPUT
3 TRANSMIT DATA (TXD) OUTPUT
4 NOT CONNECTED
5 ISOLATED SIGNAL GROUND (GND)
6 NOT CONNECTED
7 READY TO SEND (RTS) OUTPUT
8 CLEAR TO SEND (CTS) INPUT
