HARDWARE AND SOFTWARE SETTINGS
Selecting the Operation Mode
There are eight 3-pin DIPswitches, SW1~SW8 on PCIe-800i and PCIe-800i-SI cards. The
DIP switches are used to select the mode of operation. You will need to set the switch
settings to RS-422 mode or RS-485 mode as per the requirements of your application.
The RS-422 & RS-485 mode block configuration settings are listed as follows.
SW1~SW8 for Mode Setting

Note: When PCIe-800i and PCIe-800i-SI are working in RS-485 operation mode, you
need to enable the automatic direction control of the RS-485 transceiver buffer by
setting the driver configuration (refer to page 11).

10
Enabling Termination Resistors
There are eight 2×3 pin jumper header blocks, JP1~JP8, on PCIe-800i and PCIe-800i-SI
cards. The jumper header blocks are used to enable TxD, RxD 120Ωtermination
resistors, with JP1 for port 1, JP2 for port 2 and so on. You will need to set the jumper
header blocks as per the requirements of your application. Settings are listed as
follows:

11
Enabling Automatic Direction Control in RS-485 Mode
When PCIe-800i or PCIe-800i-SI is working in RS-485 operation mode, you need to
enable the automatic direction control of the RS-485 transceiver buffer by settingthe
driver configuration.
1. Double click on “Exar’s Communications Port (COMx)” under Device Manager to
enter “Exar’s Communications Port (COMx) Properties”. Check “RS-485” and click
“OK” to enable the automatic direction control of the transceiver buffer in RS-485
operation mode.
2. Repeat the steps above for other COM ports to enable automatic direction control
for all ports.

WIRING INFORMATION FOR RS-422/485
This section will provide proper wiring information about RS-422 and RS-485 data
communication. It is necessary to have the basic knowledge to avoid or find errors in
data transmission. Failures in cabling are responsible for the vast majority of
transmission problems.
RS-422 and RS-485 TransmissionTechnique
RS-422 and RS-485 use the same balanced transmission method. Signals are not
transmitted as voltage on a single wire like in RS-232. Instead, two wires are used;
when one carries high voltage, the other one carries low voltage. The signal is defined
by the difference in voltage between those two wires. This hardens the transmission
against noise. Usually, twisted pair cables are used, which further reduces the
sensitivity to noise.
To make sure the signals meet the common voltage range, the GND of sender and
receiver must be connected. To ensure the signals are in the valid voltage range so
that the differential voltage can be correctly sensed by the receiver, the GND lines of
the transmitter and receiver must be connected.

13
RS-422 Connected
The following diagram shows RS-422 without handshaking signals connected.

14
RS-422 and RS-485 4 Wire Scheme
RS-422 requires dedicated wire pairs for transmit and receive. The transmit wires are
used to send data to as many as 10 receivers, as stated in the specificationsof RS-422.
Since the PCIe-800i and PCIe-800i-SI use RS-485 Line Driver technology, up to 32
receivers are possible.
The following diagram shows RS-422 and RS-485 4 wire scheme:
The following diagram shows RS-485 2 wire scheme:

7. Select “Device Manager”.

17
8. Under “Device Manager” of the system properties, you can find “PCI Serial Port”
attached to “Other devices”. Select “PCI Serial Port”.
9. Select “Action” and execute “Update Driver Software”.

18
10. Click “Browse my computer for driver software”.
11. Insert the driver CD into the CD-ROM or DVD-ROM drive.
12. Select the directory "\PCIe Drivers\x86” for 32 bits Windows OS (“\PCIe
Drivers\x64 for 64 bits Windows OS”) as the target. Click on "OK", and on “Next”
to install driver.

19
13. After driver installation is done successfully, you will find “Exar’s 8-port UART
PCI-Express Card” and eight instances of “Multifunction Device” under Device
Manager.
14. Select the first “Multifunction Device”.
