2. Setup
Plugging the Board
(1) Before plugging the board, shut down the syste m, unplug the power code of you r PC.
(2) Remove the cover from the PC so that the board can be mounted.
(3) Plug the board into an expansion slot.
(4) Attach the board bracket to the PC with a screw.
(5) Put the cover back into place.
CAUTION
- Do not touch the board's metal plated terminals (edge connector) with your hands.
Otherwise, the board may malfunction, overheat, or cause a failure.
If the terminals are touched by someone's hands, clean the terminals with industrial alcohol.
- Do not install or remove the board to or from the slot while the computer's power is turned on.
Otherwise, the board may malfunction, overheat, or cause a failure.
Doing so could cause trouble. Be sure t hat the pe rson al com puter or t he I/O e xpan sion unit pow er is
turned off.
- Make sure that your PC or expansion unit can supply ample power to all the boards installed.
Insufficiently energized boards could malfunction, overheat, or cause a failure.

Step 2 Installing the Hardware
For using an expansion board under Windows, y ou have t o let the OS detect the I /O addresses and IRQ to
be used by the board. The process is referred to as installing the hardware.
In the case of using two or more boar ds, make sur e you install one by one with the F ound New Hardware
Wizard.
Turning on the PC
Turn on the power to your PC.
CAUTION
- Refer to the API-PAC(W32) "Hardware Installation Procedure (HWINSTU.CHM)" help file for the
procedure to follow when using API-SIO in the "Driver Library API-PAC(W32)".
If using API-SIO from API-PAC(W32), install from API-PAC(W32) instead of from the supplied
CD-ROM. If you install from the CD-ROM by mistake, uninstall API-SIO as described in
"Uninstalling the Driver Software" in "Chapter 5 Software".
- The board cannot be properly installed unless the resources (I/O addresses and interrupt level) for
the board can be allocated. Before attempting to install the board, first determ ine what PC resource s
are free to use.
- The resources used by each board do not depen d on the locatio n of the PCI E xpress slot or the b oard
itself. If you remove two or more boards that have already been installed and then remount one of
them on the computer, it is unknown that which one of the sets of resources previously assigned to
the two boards is assign ed to th e re mo unt ed b oard. In this case, you must check the resource
settings.

The connector used for COM-8C-PE has a wide interpin space and is highly reliable. In the case of a PC with a narrow
slot opening, a gap might be created as wide as the thickness of the sheet metal of the PC when an external cable is
connected, preventing the connector from being fitted properly. If the thickness of the sheet metal is less than 1.5mm
(typically about 1.0mm), simply tighten the adjusting screw located on the side of the connector to install it properly.
The connector should function without a problem.

Types of Cable and Example Connections
When using an RS-232C interface, different cables are required depending on the type of device to
which you are connecting (computer or modem, etc.). Check the requirements of the external device and
select either a straight-through or cros se d (n ull m odem) cable as appropriate. If special treatment of the
signal lines in the conn ec tor is requ ir ed, ensu re th at this is done in accordance with the specifications.

4. Functions
4. Functions
This section describes the functions of the board.
Communication Function
Serial Data Transmission
Sends and receives data in accordance with the RS-232C standard.
The baud rate for each channel can be set independently in the range 2 - 921 ,600bps by soft ware.
RS-232C Control Lines
All ports include the RTS, CTS, DTR, and DSR control lines.
The lines can be controlled or monitored by software from the application
Send and Receive Data Buffers
Each channel has a separate 128-byte send and 128-byte receive buffer.
The buffers operate as FIFO buffers and help reduce the load on the CPU for high-speed
communications or system operation.
The data buffer settings (Use FIFO ON/OFF and FIFO trigger size) are set by the Device Manager.
The FIFO trigger size specifies the data buffer size and determines the timing for generating hardware
interrupts.
Setting a large FIFO trigger size lightens the load on the CPU by reducing the number of hardware
interrupts generated by sending or receiving data.
However, as data is not actually sent or received until a certain amount of data has accumulated, the
timing at which the data reaches the opposing device is slightly delayed. Similarly, there is also a delay
in the timing between data being received and the data being passed the application.
Alternatively, setting a small FIFO trigger size or disabling FIFO operation increases the speed of data
sending and receiving but increases the load on the CPU and risks received data being missed.
As the FIFO trigger size is variable, you can adjust this sett ing to achie ve optim um perform ance for y our
system.

4. Functions
Setting the Baud Rate
The output baud rate can be s et by sett ing the appr opriate va lue to the Baud Rate Genera tor re gister. The
available setting range depends on which clock mode is used.
Clock 3 mode: 15 - 921,600bps
Clock 2 mode: 8 - 460,800bps
Clock 1 mode: 4 - 230,400bps
Clock 0 mode: 2 - 115,200bps
However, some baud rate values do not have a corresponding Baud Rate Generator register setting. If
the result of substitutin g the baud r ate into the equation be low is an integer, then that baud rate can be set.
If the result contains a fractional part, the baud rate cannot be set.
Clock 3 mode
921600 ÷ Desired baud rate = Division register setting value
Ex.) 921600 ÷ 9600bps = 96 (As the result is an integer, this baud rate can be set.)
921600 ÷ 128000bps = 7.2 (As the result contains a fractional part, this baud rate cannot be set.)
Clock 2 mode
460800 ÷ Desired baud rate = Division register setting value
Ex.) 460800 ÷ 9600bps = 48 (As the result is an integer, this baud rate can be set.)
460800 ÷ 128000bps = 3.6 (As the result contains a fractional part, this baud rate cannot be set.)
Clock 1 mode
230400 ÷ Desired baud rate = Division register setting value
Ex.) 230400 ÷ 9600bps = 24 (As the result is an integer, this baud rate can be set.)
230400 ÷ 128000bps = 1.8 (As the result contains a fractional part, this baud rate cannot be set.)
Clock 0 mode
115200 ÷ Desired baud rate = Division register setting value
Ex.) 115200 ÷ 9600bps = 12 (As the result is an integer, this baud rate can be set.)
115200 ÷ 76800bps = 1.5 (As the result contains a fractional part, this baud rate cannot be set.)
CAUTION
The "Driver Library API-PAC(W32)" and the "Standard COM Driver Software COM Setup Disk"
from the supplied CD-ROM use "Clock 3 mode". (Fixed)
CAUTION
As Visual Basic's communication control (MSComm) accepts any available baud rate settings,
using the MSComm functionalities limits the rate to 115,200bps maximum. For setting the baud rate
higher than 115,200bps using Visual Basic, refer to the VB sample program included in the
accompanying CD-ROM “Standard COM Driver Software COM Setup Disk”.
