1.1 Description
1.1.1 PCI Express Bus
The PCI Express Bus is a high-speed, scalable I/O serial bus technology that is
standard designed to replace the PCI bus. Thus, PCI Express has numerous advantages such as higher maximum system bus throughput, less I/O pin, more detailed
error detection and reporting mechanism, and smaller physical footprint. Although, at
the hardware level PCI slots and PCIe slots are not interchangeable, at the software
level PCI Express preserves compatibility with PCI device drivers and OS.
PCI Express is a point-to-point connection, which means it does not share bandwidth
but communicates directly with devices via a switch that directs data flow. By adding
more lanes, scalable features can be achieved for greater bandwidth.
The PCIe link between PC and other devices can consist of 1 to 32 lanes. These
numbers indicate the number of lanes you wish to have. For example, PCIe x16 has
16 lanes.

2. ICOM CD-ROM including:
a. User manual
b. Industrial Communication Driver
c. Utility tool
We carefully inspect our PCI/ PCI Express communication card mechanically and
electrically before shipping. It should be free of marks and scratches and in perfect
working condition on receipt.
As you unpack, check for any signs of shipping damage (damaged box, scratches,
dents, etc.). Should any damage is found or fails to meet specifications, please notify
our service department or your local sales representative immediately. Also the carrier should be notified. Retain the shipping carton and packing material for further
inspections by the carrier.
After inspection we will make arrangements to repair or replace the unit.
When you handle the communication card, remove it from its protective packaging by
holding the rear metal panel. Keep the anti-vibration packaging for further storage, as
the card was removed from the PC.
Warning! Discharge your body’s static electric charge by touching the back of the
grounded chassis of the system unit (metal) before handling the board.
You should avoid contact with materials that hold a static charge such
as plastic, vinyl and styrofoam. Handle the board only by its edges to
avoid static damage to its integrated circuits. Avoid touching the
exposed circuit connectors. We also recommend that you use a
grounded wrist strap and place the card on a static dissipative mat
whenever you work with it.

default configuration and your options for each jumper.
2.3.1 How to Set Jumpers
Configure the card to match the needs of your application by setting jumpers. A
jumper is the simplest kind of electric switch. It consists of two metal pins and a small
metal clip (often protected by a plastic cover) that slides over the pins to connect
them. To “close” a jumper, connect the pins with the clip. To “open” a jumper, remove
the clip.
You may find a pair of needle-nose pliers useful for setting the jumpers.
If you have any doubts about the best hardware configuration for your application,
contact your local distributor or sales representative before making any changes.
Figure 2.7 How to Set Jumpers
2.3.2 Default Settings
The card is shipped with default settings. If you need to change these settings, however, refer to the following sections.

2.3.3.3 Termination setup (for PCIE-1602B/1602C/1612B/1612C/1622A/1622B/1622C)
You can set termination resistors if necessary to match impedance. Each signal line
(Tx, Rx) has a separate resistor.
Note!
Especially in fields with serious electric noise, setting termination resistors is helpful to stabilize communications. Make sure that both sides of
the RS-485 bus have termination resistors. See details in Chapter 5.2.2
and 5.2.3.
Termination is recommended for use when designing a RS-422 interface.
RS422 mode with terminator resistor is 120ohm on standard condition. But the transmission condition is impacted by the impedance of cable length.

4.3.3 Com Port Tab
Each Com Port tab represents a specific port you have selected for test and configuration. On the tab, you can see the Transfer Mode, Port Status, and Message Logo
area.
Transfer Modes
You can specify the transfer mode to be Normal, loopback (active) or loopback (passive).
Normal—allows data to be transmitted and received simultaneously. The data reception rate is helpful in identifying the performance of a communication card installed on
your system.
Loopback- In loopback mode a series of special data will be transmitted, which are
expected to appear on the receiving end. Using the loopback mode, you can check
the integrity of received data and find whether any error occurred on the transmission
line. The active loopback and passive loopback must work in pair to enable the loopback mode. When a port operates as active loopback mode, it will send data first and
receive data later. Another port, which operates as passive loopback, will retransmit
any received data on the Rx line and then send these data onto the Tx line. These
two modes will form a logical loop and help to verify the integrity of data transmitted
over the communication link.
4.3.4 Port Status
DTR (data-terminal-ready)
DSR (data-set-ready)
RTS (request-to-send)
CTS (clear-to-send)
CD (carrier-detect)
For RS-232 specifications, DTR and RTS are for output signals and can be toggled
on and off by double-clicking the labels (such as DTR, DSR, RTS, CTS, CD) under
the red/green marks. However, if you are using RTS/CTS for flow control to run the
test, you will see the RTS mark appear in black. This indicates that the RTS can no
longer be toggled on/ off since it is controlled by driver itself.

PCI Express-Communication User Manual
Pin Assignments and Wiring
Since the RS-232 interface is not strictly defined, many devices have their own connection methods which may ignore some signal lines or reserved lines for other functions. It is best to refer to the user’s manual of your device for installation instructions.
You may find the following helpful.
In general, DTE (Data Terminal Equipment) refers to the device that is leading the
communication. Examples include PC’s, terminals and some printers. DCE refers to
the device being communicated with or controlled. Examples include modems,
DSU’s (digital service units), printers and lab/factory equipment.
In some situations you may be able to get by with just three lines: data on TXD, a signal ground and a handshaking line. Examples are printer or plotter connections, troubleshooting and situations where you require only one-wire communication.
Chapter 5
5.2 Wiring
For DTE to DCE connections, use a straight through cable (i.e., you don't have to reverse
lines 2 and 3, lines 4 and 5, and lines 6 and 20 since, in general, the DCE RS-232 interfaces
are reversed themselves).

Therefore, if you are not using CTS, RTS, DSR,DTR and DCD signals, short pins 4 and 5
together, and please short pins 6, 8,and 20 together.
5.2.2 RS-422 Signal Wiring
The RS-422 interface wiring is based on one-on-one principles. The transmit lines on
one side connect to the receive lines on the other side, and vice versa. With RS-422,
you can transmit and receive data simultaneously (full duplex). The connections are
as follows:

Termination Resistors Setup
Termination resistors are on-board and can be selected by jumper for 120 or 300
Ohms. Each pair of signal lines has a separate resistor (RxD+/-, TxD+/-).
PCI Express-Communication User Manual
44
The RS-485 standard supports half-duplex communication. This means that just two
wires are needed to both transmit and receive data. Handshaking signals (such as
RTS, Request To Send) are normally used to control the direction of the data flow
and to switch the transmission accordingly. In RS-485 mode, the PCIe-1602/1612/
1622 cards automatically sense the direction of the data flow and switch the transmission direction — no handshaking is necessary. This means a user can build an
RS-485 network with just two wires. This RS-485 control is completely transparent to
the user. The software written for half duplex RS-485 works without any modification.
