6.1 Jumper Settings

These cards feature built-in termination resistors for each serial port. You can
modify the jumper settings (short the pins) to avoid impedance mismatch
problems when operating under multi-drop transmission.

When an electrical signal travels through two resistance junctions in a
transmission line, the impedance mismatch will sometimes cause signal
reflection. Signal reflection causes signal distortion, which in turn contributes to
communication errors. The solution to this problem is to establish the same
impedance at the line ends as in the line itself by terminating them with
resistors. It is normally sufficient when the value of the termination resistors
equals the characteristic impedance of the transmission line. LINDY
RS-422/485 serial boards feature built-in termination resistors to prevent these
problems.

: \PCI IO\win9x\

- 15 -

(4) The system will search and install the appropriate IO driver automatically.
Please click “Next” to continue.

(5) Please click “Finish” to complete this installation step.

Note:

The “Add New Hardware Wizard” windows will display and install drivers
several times until you finish setting up each serial port.

7.7 Verifying Serial PCI card installation:

- 16 -

When Windows has finished installing the driver you must check:

Control Panel > System > Hardware > Device Manager >Ports[COM&LPT]

It will show the additional ports:

Note:

1. If you have installed PCI Serial ports in your system, you will be requested
to restart your computer , when you have finished setting up each serial port.
Click “Yes” if all serial ports have been installed, otherwise click “No”.

2. The item number you see during the installation may be different from the
item you have installed.

- 17 -

 8.0 Configure COM port

(1) Select the PCI Serial Port which you want to configure, for example COM3.
Right click the mouse, and select “Properties”.

(2) Click “Port Settings”.
Configure the Bits per second, Data bits, Parity, Stop bits and Flow control if
you want to change them.

There are three kinds of flow control: Xon/Xoff, Hardware and None.
Xon/Xoff is using software protocol. Hardware means the flow control is using
RTS/CTS, but the RTS/CTS is controlled by software. None means there is no
flow control.

- 18 -

Click the “Advanced” button to set more advanced features.

(3) Configure the “Enable Auto CTS/RTS Flow Control ”,“ 16/32 bytes FIFO
length and Receive/Transmit Buffer trigger level if you want to change these
settings

(The 128K software FIFO adjustment only supports Microsoft Windows 2000
/ XP / 2003 OS. You can change the FIFO size and COM port Number as
you need.)

The window below would be shown under Windows 2000/XP/2003.

The window to the right would be
shown under Windows 95/98SE/ME.

*Enable Auto CTS/RTS Flow Control

means the CTS/RTS flow control is
controlled by hardware automatically.
The system will be more stable if the
function is enabled.

*Setting the Receive/Transmit Buffer to a higher value will get faster

performance because the CPU interrupts will be reduced, but the time for
interrupt service routine will become shorter. If the system is not stable, reset
the lower value to solve problem.
