Overview

Product Overview

The RocketPort INFINITY is a high-speed in-server serial expansion card that is
RS-232/422/485 software-selectable for use in 3.3V universal PCI or PCI-X slots in
a host system. The RocketPort INFINITY was designed to support speeds up to
921Kbps (if connected, using fan-out cables) or 460.8Kbps (if using an interface
box).

The RocketPort INFINITY series uses Comtrol Application Specific Integrated
Circuit (ASIC) technology to replace most hardware functionality to minimize
components, including:

• The processor

• A serial controller

• Bus interface logic and other miscellaneous logic

You can install up to four RocketPort INFINITY cards in one computer, providing
a maximum of 128 additional serial ports.

Before Installing the RocketPort INFINITY

If you are planning on installing the RocketPort INFINITY in a Windows system
make sure that you have located the device driver assembly to a location that is
available to the host system before installing the card in the host.

You can use the Software and Documentation CD to locate the latest device drivers
and documentation or use the files on the CD for your installation. Optionally, you
can use the links in the following table.

You may want to record the model and serial number of the RocketPort INFINITY
before installing the card in the event you need to call technical support.

Locating the Latest Drivers and Documentation

This table contains links the software and installation documentation. Optionally,
you can locate the latest device drivers, software, and installation documentation.

The transmit LED is illuminated when RS-232/422/485 data is being
transmitted. Noticeable flashing occurs only if transmit data starts and stops
a few times per second or less. Otherwise, if data is being transmitted
continuously, the LED illumination appears to be constant. If no data is
transmitted the LED is off.

DTE Versus DCE

Connecting Serial Devices

This section provides information about the RocketPort INFINITY connectors, in
the event that you need to build cables or loopback plugs.

• DB9 Serial Cables and Loopback Plugs

• DB25 Serial Cables and Loopback Plugs

• RJ45 Serial Cables and Loopback Plugs

A loopback plug is a serial port plug with pins wired together that you can use
with application (for example, the diagnostic, Test Terminal, or minicom) to test
serial ports. See Before Calling Technical Support
about using the test application shipped with the RocketPort INFINITY.

Most devices, except modems, are Data Terminal Equipment (DTE) devices.
Modems are Data Communication Equipment (DCE) devices. RocketPort
INFINITY ports are configured as DTE.

How you build a cable depends on which device your are connecting to (DTE or
DCE). For example, you need a null-modem cable to connect the COM ports
(COM1 or COM2) on the computer or the RocketPort INFINITY ports to printers,
terminals, bar code readers or DNC equipment. If you are connecting a DTE
device to a DCE device you need a straight-through modem cable.

• Straight-through cable (DTE to DCE) - connects TxD to TxD and RxD to RxD.

• Null-modem cable (DTE to DTE) - connects TxD to RxD and RxD to TxD.

RocketPort INFINITY Diagnostics

This subsection describes how to run the bootable diagnostic CD to verify that the
RocketPort INFINITY hardware is functioning properly. The RocketPort
INFINITY is shipped with a bootable CD that executes hardware diagnostics.

In the event that you cannot locate the CD, you can download
and burn the .iso image to a CD-ROM.

You can use the diagnostic to:

• Confirm that the hardware is functioning

• Determine resolutions to conflicts during installation

• Perform a stress test on all RocketPort INFINITY ports in the system

The diagnostic requires a loopback plug to test a port or ports. A single loopback
plug is shipped with the RocketPort INFINITY. You can build additional loopback
plugs or move the loopback plug to the port you want to test. See Connecting

Serial Devices on Page 11 if you want to build loopback plugs.

Use the following procedure to run the diagnostics.

1. Insert the bootable CD that contains the diagnostic and restart your machine.

The diagnostic starts automatically and takes a few minutes before the first
screen appears.

2. Press Enter at the disclaimer screen to begin the diagnostic.

Note: If the diagnostic goes into sleep mode while unattended, press the Num

Lock key to activate the screen.

3. Enter 1 to 4 to test a port or ports on a specific RocketPort INFINITY, or select

S to run the stress test on all RocketPort INFINITY cards installed in the

system.

Note: The stress test requires a loopback plug for each port on each card.

Use Ctrl/Alt Delete to kill the diagnostic process at any time.

Testing a Port or Ports

Enter A to test all ports on the RocketPort INFINITY or enter the port number
of a port that you want to test and follow the instructions on the screen. If you
are testing all of the ports and have only one loopback plug, you must move it
from port to port during the test.

Stress Testing the RocketPort INFINITY

The stress test uses a default configuration to simultaneously stream data to
all ports of the RocketPort INFINITY cards in a system until you stop the test.
To stop the test and review the results of the stress test, enter S.

To end the diagnostic, you may need to select b to return to a screen that contains
a q to quit. Type reboot, select Enter, and remove the CD from the drive when
prompted.

If the diagnostics did not detect a hardware problem, you may have a device driver
problem. See Before Calling Technical Support

Use the following procedures to run Te s t Ter mi na l tests.

Test Terminal Explanation

Using Test Terminal
to T

This subsection provides background information about the two tests procedures
in the following subsection.

• Send and Receive Test Data: This sends data out the transmit line to
l

oopback plug, which has the transmit and receive pins connected thus

the

sending the data back through the Rx line to Test Terminal, which then
displays the received data in the terminal window for that port. This test is
only testing the Tx and Rx signal lines and nothing else. This test works in
either RS-232 or RS-422 modes as both modes have transmit and receive
capability. A failure in this test will essentially prevent the port from working
in any manner.

• Loopback Test: This tests all of the modem control signals such as RTS, DTR,
CTS, DSR, DCD, and RI along with the Tx and Rx signals. When a signal is
made HI in one line the corresponding signal line indicates this. The Loopback
Te st changes the state of the lines and looks for the corresponding state
change. If it successfully recognizes all of these changes, the port passes.

A failure on this test is not necessarily critical as it will depend on what is
connected and how many signal lines are in use. For example, if you are using
RS-232 in 3-wire mode (Transmit, Receive and Ground) a failure will cause no
discernible issue since the other signals are not being used. If the port is
configured for use as either RS-422 or RS-485 this test will fail and is expected
to fail since RS-422 and RS-485 do not have the modem control signals that
are present in RS-232 for which this test is designed.

The following procedure shows how to use Test Terminal to send and receive test
data to the serial ports and run a loopback test.

1. Stop all applications that may be accessing the ports such as RAS, RRAS, or
any faxing or production software. See the appropriate help systems or
manuals for instructions on stopping these services or applications. If another
application is controlling the port, then Tes t Te r m in a l will be unable to open the
port and an error message will be shown.

Note: Remember to restart the application once testing of the ports has been

completed.

Troubleshooting

The loopback test test the modem control (hardware handshaking) signals. It
only has meaning in RS-232 mode on serial connector interfaces with full RS­232 signals. If performed under the following conditions, the test will always
fail because full modem control signals are not present:

•RS-422

•RS-485

• RJ11 connectors

If both of these tests successfully complete, then the port is operational as
expected.

Note: Do forget to restart the application.

Troubleshooting Linux Systems

You can use the following subsections to test the serial ports.

lcom(1)

Comtrol has available lcom(1), which is a multiport serial I/O test program. You
can use lcom in test mode to send test data to any serial port.

lcom is available on the Software and Documentation CD or you can download

the

latest version.

Note: For assistance using lcom, use the manual page, lcom(1) that accompanies

the program.

File Transfer You can transfer a file using the following information. The default settings are

9600, 8, n, 1, and no parity. To send a file you can redirect output to a device; for
example:

cat /etc/inittab > /dev/ttyRP0

Sends the contents of the /etc/inittab file to the ttyRP0 device at 9600 baud, 8, n, 1,
and no parity.

Use the following information if you need assistance changing or viewing the baud
rate settings.

To change the baud rate, use the following example, which changes the baud rate
to 19200:

stty 19200 </dev/ttyRP0

To view the current serial port settings for ttyRP0, enter:

stty -a </dev/ttyRP0

Note: Settings changes via stty are only valid during current log in session. For

permanent setting changes, use the /etc/inittab file.
