Jumper Settings

For RS-422/485 serial communications, when an electrical signal travels
through two different resistance junctions in a transmission line, the impedance
mismatch will sometimes cause signal reflection. Signal reflection causes signal
distortion, which in turn will contribute 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.

Ideally, the two ends of the cable will have a termination resistor connected
across the two wires. Without termination resistors, reflections of fast driver
edges can cause multiple data edges that can cause data corruption.
Termination resistors also reduce electrical noise sensitivity due to the lower
impedance, and bias resistors (120 ohms for twisted pairs) are required. The
value of each termination resistor should be equal to the cable impedance.

___________________________________________________________________________________

16

RS-422 or 4-Wire RS-485 working model with termination resistor:

2-Wire RS-485 working model with termination resistor:

SUNIX RS-422/485 PCI Serial board equips independent TX and RX
termination resistors for each serial port. User can modify the jumper setting
(short the pins) to avoid impedance mismatched problem when operate under
Multi-drop transmission. Resistors should be added near the receiving side.
Note: Stands for termination resistor near the receiving side.

Manufactory default jumper setting is OPEN (disable 120 ohms termination
resistors across the two wires).

Port Configuration

______________________________________________

This chapter shows all Serial COM port settings that user came with usually,
such as COM port number, FIFO length(size), baud rate, IO address and others.

The following topics covered in this chapter:

 Configure Serial Port Settings
 COM Port Number Settings
 COM I/O Resource
 FIFO Settings
 Advanced Settings for RS-422/485 Communication

___________________________________________________________________________________

28

Configure Serial Port Settings

After the board and serial port drivers are installed, please refer to following
instructions to configure Serial COM settings.

(1) Please launch the “Device Manager”.
(2) Right click the “SUNIX Serial Card” item from the “Multifunction adapters”

sub-tree and click “Properties”.

(3) On the “Port Control” tab, select a port to configure.

* Click “OK” to approve the settings for the selected port.
* Click “Set to All” to approve the settings for all COM ports.

___________________________________________________________________________________

29

COM Port Number Settings

Under Port Number, select a COM number to assign to the serial port. Click
“OK” to approve the settings for the selected port.

Note: In order to prevent system resource conflict, do not select “in use” port.

COM I/O Resource

User can read the COM “IO Range” and “IRQ” located in system by selecting
COM port.

IRQ and I/O address is automatically assigned by the mainboard PCI BIOS
automatically (before COM card driver installing). User can NOT assign legacy
ISA address (3F8, 3E8, 2F8, 2E8) for the specific COM port. But for IRQ setting,
user can set specific IRQ value for this PCI bus slot via mainboard’s BIOS
settings (not via SUNIX driver). But all COM ports will share one IRQ value.

___________________________________________________________________________________

30

FIFO Settings

Select an Rx FIFO Trigger and Tx FIFO Size.
The default Rx FIFO Trigger is 112 bytes. The default Tx FIFO Size is 128 bytes.
Click “Set to All” to change this setting for all serial ports on the board. Then
click “OK” to save the settings.

Receive FIFO interrupt trigger level:

When the level of data in the receiver FIFO reaches this value, a receiver data
interrupt is triggered.

Transmit FIFO interrupt trigger level:

When the level of data in the transmit FIFO falls below this value, a transmitter
interrupt is triggered. Setting this value to zero will not trigger an interrupt until
the transmitter is completely idle.

The FIFO trigger levels can be fine tuned to gain optimum performance,
depending on system performance, baud rate used, levels of serial traffic etc.

___________________________________________________________________________________

Advanced Settings for RS-422/485 Communication

User can control RS-422/485 communication in Advanced Port Control page
through “Advanced” settings.

Clock Rate

This is the “Data Rate" value for on board crystal frequency of input clock. The
baud rate can optionally be adjusted according to the data rate required. The
clock pre-divisor is used to divide the input clock prior to baud rate generation.

This parameter must matches with the oscillator (crystal) frequency on the board.
System default is 14745600 Hz. We do NOT recommend for modification
without SUNIX instruction. User can click “Defaults” button back to manufactory
settings.

UART Type (Default: Auto RS-422/485 )

User can select RS-422 or RS-485 interface for each COM port of this board.

1). Auto RS-422/485

SUNIX developed a unique technology “Auto Detect & Switching RS-422/485,
which can automatically detect the state of RS-422 full duplex or RS-485 half
duplex and control the data transmitting and receiving wires at the same port
without any hardware or software settings.

2). RS-422 (4-Wire RS-485)

This COM port forces to run RS-422 full duplex mode.
(RS-485 ACS function can not open under this mode.)

3). RS-485

This COM port forces to run RS-485 half duplex mode.

___________________________________________________________________________________

33

RS-485 ACS™ Technology (Default: Enable)

Auto Carrier Sense (ACS™) technology is the data flow control under RS-485
half duplex (one-way traffic) communicating. It manages data flow between
computers or devices or between nodes in a RS-485 network, so that the data
can be handled at an efficient pace

Auto Carrier Sense (ACS™) technology will check the status of RS-485
communication bus. If the bus is idle, it starts transmission. If the bus is not idle
(some data flows in the bus), then it will postpone the transmission of UART until
the bus is idle. Due to the reduction of TX/RX packet conflicting on RS-485
one-way traffic bus, it will enhance better system performance and RS-485
communication ability.

___________________________________________________________________________________

34

RS-485 AHDC™ Technology

Since RS-485 is bidirectional which means the driver is turned on only when it
needs to transmit some data, otherwise it is floating. SUNIX developed a new
design to control the direction of driver (On or off) automatically which is called
Auto Hardware Direction Control/Carrier Sense. AHDC/CS™ works on the same
principle and only turns on the driver when UART needs to transmits some data;
but the advantage is that AHDC/CS™.

Auto Hardware Direction Control (AHDC™) technology makes it easier to
manage 2-wire RS-485 half-duplex communications, eliminating the need for
software interference. User does not necessary to write extra code for Windows
applications to control the half-duplex protocol. Auto Hardware Direction Control
(AHDC™) technology is the key feature of SUNIX UART, and this function is
default enabling.

______________________________________________

This chapter shows some problems that user came with usually. Also you can
check it if the PCI serial board can not work properly in your system after
following hardware and software installation steps. In addition, you could contact
with us for detail technical product information.

In this appendix, we cover the following topics.

 Troubleshooting
 Product Family
 Contact Information

___________________________________________________________________________________

36

Troubleshooting

1. System fails to find the PCI serial board or COM port.
A: It may cause by following issue:

a. The board is not properly plugged into the PCI slot.
b. Please clean the golden finger.
c. The PCI slot is defective. Please try other slots until you find one that

works.

d. The mainboard does not have an available IRQ for the PCI serial board.

Enter the PC.s BIOS and make sure an IRQ setting is available in the
PCI/PnP settings.

e. The board itself might be defective. You can try another mainboard testing

this board working or not.

2. There is a blue screen when I entry operation system.
A: The possible reason is an IRQ or I/O address conflict with other PCI bus

adapters, such as LAN or serial boards, or with the system BIOS. Refer to
the corresponding problem in the previous FAQ for solutions.

3. There are some exclamation marks in device manager and serial ports

can not work properly.

A: It caused by the wrong driver installing or hardware settings. Please turn off

your computer firstly and re-install hardware and software, especially
re-install the correct driver.

4. Should I enable auto flow control features?
A: Enable Auto CTS/RTS Flow Control means the CTS/RTS flow control is

controlled by hardware automatically. System will be more stable if the
function is enabled. Please make sure your serial device and cable wiring
before enabling the hardware flow control function.

___________________________________________________________________________________

37

5. How large FIFO length I should set?
A: FIFO (First-in-First-out) buffers are used to reduce the frequency of interrupt

processes for UART chips. The size of the buffer will determines the number
of times the cards need to interrupt the computer’s CPU in order to process a
string of data. With larger FIFO buffer size; there is more data flow and less
interruption to the CPU, therefore allowing the CPU to be free to handle other
more crucial tasks.

Set the Receive/Transmit Buffer to higher value will get faster performance
because the interrupts will be reduced, but the time for interrupt service
routine will become shorter. The receive buffer overflow will be easily
happened if the CPU speed is not enough to handle. If the system is not
stable, select the lower value to correct problems.
