CHAPTER
Introduction
This chapter introduces PCI-1625U, its
accessories and detailed specifications.
Sections include:
• Description
• Features
• Specifications
• Ordering Information
Chapter 1 Introduction
1.1 Description
The intelligent PCI-1625U 8-port RS-232 interface card was designed for
lab and industrial applications where a PC needs to communicate with
terminals, modems, or other instruments. You can install up to four PCI1625U cards for a total of 32 ports in any PCI bus-based PC.
PCI-1625U is virtually a self contained computer. The PCI-1625U card
has an onboard DSP processor that takes over the processing load from
the host PC. When you are transferring large amounts of data from multiple ports, servicing the interrupts alone consumes a large percentage of
the capacity of your computer's CPU. PCI-1625U serves as a high speed,
dedicated interrupt processor.
The processor also has 1 MB of SRAM which can store serial data and
reduce host CPU loading effectively. When PCI-1625U initializes, it
downloads the driver software (which functions like a PC's BIOS) into its
onboard DSP. This improves performance and makes version upgrading
easy so there is no hardware redundancy.
PCI-1625U has a universal PCI connector that is compatible with both
newer 3.3 V signaling systems and the traditional 5V signaling system.
This gives high compatibility and allows usage in diverse systems.
Besides, Advantech provides a convenient utility program, ICOM Tools,
to help users test the PCI card performance by analyzing a port’s status.
It’s easy to use the menu commands and toolbar buttons. ICOM Tools
acts as a PC-based data scope that lets you set a trigger condition, capture
the communication data and monitor the signal status. ICOM Tools is
applicable to all series of Advantech ICOM cards.
PCI-1625U also has many accessories to make usage more convenient.
You can use OPT8AP,OPT8ASP,OPT8BP,OPT8BSP, extending module
boxes to access 8-port RS-232 devices, or OPT8C and OPT8H, extending
cable to access 8-port RS-232 devices, modems and terminals with any
kinds of DTE and DCE connection. You could also use OPT8FP to
access 8-port RS-422 device, OPT8FP is the RS-422 and RS232 converter connection box.

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.
27 Chapter 4
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.
A black mark represents that the function is controlled by the driver itself and therefore not controllable by software.
4.3.5 Message Logo
On the Message Logo area, you can see the relevant messages about the
port(s) you have selected.
For information about specific messages in this area, please refer to Section 4.5, Messages on the Status Bar and Message Logo area.
PCI-1625U User Manual 28
4.3.6 Tx Slide Bar

can adjust the transmission rate of your port(s) from 0% to 100%. Just
drag the slide button along the track to adjust the transmission rate.
4.3.7 Performance Listing Area
On the performance listing area, you can see the relevant information,
such as Rx Length (received packet byte length), Bytes/Sec (transmission
rate) and Last Abnormal Status of each port running a test.
4.3.8 Status Bar
The Status Bar is where you can glimpse the current information of the
port you have selected. The Status Bar indicates whether the port is
READY, RUNNING, BUSY or STOPPED, N/A PORT and the configuration information such as baud rate, data bit, stop bit, parity bit and flow
control (represented as 1200 N 8 1 None) settings. Also we can see the

PCI-1625U User Manual 32
In the Configure Port dialog box, you can configure the Baud Rate, Data
bits, Parity, Stop Bits and the flow control mode for that specific port (or
for all ports). After you have configured all the settings you want to
change, click OKto make this configuration active.
NOTE: When using All Ports Setup button or All Ports/
Setup menu command to configure settings
for all ports, you must take care to stop any ports
that are running test in order to configure them. If
you do not stop the test running on a specific
port, it won’t be configured at all. That is, you get
to configure only the ports that have been
stopped.
Run the Test
After you have completed the configuration of the port(s), you can now
start the test on the port you have selected by clicking the Run button
or accessing the Port/Run menu command (or you want to run all ports at
once, just click the All Ports Run button or access All Ports/Run
menu command).
Once the test is started, you can see relevant test information of port performance on the performance listing area.

5.2 Wiring
Since the RS-232 interface is not strictly defined, many devices have their
own connection methods, which may ignore some signal lines or define
reserved lines for other functions. It is best to refer to the user 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 PCs, 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 RxD, TxD and ground.

For DTE to DCE connections, use 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).
