Forensic Device User Advisory
We recommend that you perform a final check on your RedPort card.
Prior to first use, please verify that the write-blocking function of this product is working properly. This is
easily done: attach a SCSI storage device known to be in working order. It should contain a drive (or
drives) that you are willing to overwrite. Verify that the volume mounts properly on your computer.
Transfer files to the SCSI device. The files will appear to transfer to the drive. When the process is
complete, eject and then remount the volume. The files that you wrote to the SCSI device should not
appear after the device is remounted. If they do appear, there is a problem with your RedPort card, and
you should contact our support department for further instructions.

omponents
D). ESD
Install the RedPort write-blocking host adapter and attach your SCSI devices to it using the instructions
below.
Package Contents
The RedPort host adapter package contains the host adapter and a CD containing drivers, user manuals,
and warranty information.
System Requirements
To install and use RedPort SCSI you will need:
•A computer with an available x4 PCI Express (PCIe) expansion slot or larger, such as x8 or x16.
•An operating system supported by the card’s drivers. See Technical Specifications for a list of
supported operating systems.
WARNING: Remember to back up
your system data before changing
or installing hardware.
Installation Steps
1. Plan your SCSI device connections. If connecting both internal and external devices to the RedPort
card, be sure to have the appropriate cables to connect devices.
2. Set SCSI device termination. Devices at both ends of the SCSI bus must be terminated.
Devices in the middle of the bus, including the RedPort card, must have termination removed or disabled.
RedPort cards select the proper termination if left in auto termination mode.
3. Set SCSI IDs. Each device on the SCSI bus requires a unique SCSI ID, one different from the host
adapter ID. The default setting for the RedPort card is 7. If you need to change this setting, refer to the
ExpressPCI Utilities Installation and Operation manual. You may also need to determine and change the
current SCSI ID on the SCSI device(s) you are attaching to the RedPort card. Wide (16-bit) SCSI devices
can be assigned IDs 0 to 7 and 8 to 15, while Narrow (8-bit) devices can only be assigned IDs ranging
from 0 to 7.
4. Review system documentation to select an appropriate slot to install your adapter. The combined
power consumption of the expansion slots must not exceed the limits for your system. If you have more
than one expansion card installed, ensure power consumption is within the limits outlined for your system.
5. Power down the computer and unplug the computer from all power sources.
6. Open the case.
7. Install the adapter in any open PCI expansion slot. Consult your computer’s documentation if you have
questions about how to install an expansion card in your system.
8. Connect SCSI devices by inserting a SCSI cable to the connector on the RedPort host adapter until
you hear a click. The next section contains information on selecting cables.

9. Close the computer case and power it up.
RedPort host adapters come preconfigured to operate properly in a variety of common system setups.
However, some systems may benefit by tuning the adapter for optimal performance. Refer to the ATTO
ExpressPCI Utilities Installation and Operation manual for more information on changing host adapter
settings.
Cables and Termination
Cables and devices must be chosen to maximize performance and minimize the electrical noise from the
high-speed data transfers available with the SCSI protocol. Cabling and termination methods become
important considerations.
Exhibit 1 The following table lists the maximum number of devices you may connect at specific cable distances using
differential and single-ended SCSI in various SCSI environments.
Setting up cables and termination
Use high quality Ultra 320-rated, well-insulated SCSI cables to ensure error free communications.
Exhibit 2 Several internal and external cable connectors
The ExpressPCI Ultra320 SCSI host adapter supports two types of SCSI signaling: Low Voltage
Differential (LVD) and Single-Ended. Devices on the same SCSI bus must use the same signaling, either
LVD or Single-Ended.

WiebeTech LLC

1. Determine whether you are using a single channel or dual channel host adapter model. One external
connector indicates a single channel host adapter; two external connectors indicate a dual channel host
adapter.
2. Determine if SCSI devices are going to be installed internally or externally.
•Total bus cable length varies by host adapter and type of attached devices. Refer to Exhibit 1 for
details on maximum cable length.
•If you combine Wide 16-bit and Narrow 8-bit devices on the same connector, connect the Wide
devices first (closest to the connector).
•Refer to the documentation for your SCSI devices to determine if they are Wide or Narrow,
UltraWIDE SCSI, Ultra2 SCSI, Ultra160 or Ultra 320.
3. Determine which terminator to use
•Use an LVD terminator if you are only using LVD devices. Although you can use a Single-Ended
terminator, all devices will be limited to Ultra SCSI speeds. Single-Ended devices require a Single-
Ended terminator. If you use an LVD terminator with Single-Ended devices, the system may hang
or devices may not be seen on the SCSI bus. Some termination manufacturers provide
automatically sensing terminators.
•External terminators should be attached to the last external device in the SCSI chain. Don’t use
any other termination on the external SCSI chain. The last device on an internal SCSI chain
should also be terminated in one of several ways. Many Single-Ended Ultra SCSI and earlier
devices provide a jumper setting for applying termination: place a jumper over the pins designated
for termination on the last device on the internal cable. Check with your drive manufacturer if you
are not sure which pins to use.
•LVD Ultra2 and Ultra160 SCSI devices cannot supply their own termination. Use an internal ribbon
cable which has a SCSI terminator attached to the end of it, connect the unterminated end of the
cable to the host adapter card and the internal drives to the subsequent connectors. The
terminator should be at the opposite end of the cable from the host adapter card.
•Wide (16-bit) and Narrow (8-bit) devices can be connected together on the same connector of the
host adapter card, but wide devices must be attached first, followed by narrow devices. To
terminate the SCSI bus, the cable or adapter used to convert from a wide (68-pin) connector to a
narrow (50-pin) connector provides partial termination, allowing upper 8-bits (or byte) of the wide
SCSI bus to be properly terminated. A narrow terminator should be used on the last narrow
device to terminate the rest of the SCSI bus. A SCSI bus without partial termination between the
wide and narrow devices may at first appear to work correctly, but occasional I/O errors occur
without proper termination.
•If you use both internal and external connectors and mix Single-Ended and LVD devices on the
same bus, even if using different connectors, the host adapter card will operate with Single-Ended
signaling at UltraSCSI speeds.
•Automatic termination – When both internal and external connectors are used, the host adapter
card detects the presence of devices and turns off termination. If devices are removed from one
connector of the card, the host adapter automatically detects the change, and enables its own
termination.
•Software controlled termination – You may have to override the host adapter’s automatic
termination if only narrow devices are attached to one connector and wide devices are attached to
the other connector on the same bus. The host adapter must supply partial termination to the
upper 8-bits (byte), but not automatically. Please refer to your ExpressPCI Utilities manual for
instructions on setting the host adapter’s termination to Upper Byte.
•Termination power – Host adapters supply termination power to the bus at all times and many
SCSI devices are also able to supply termination power. SCSI signal quality, particularly with long
or marginal quality cables, may be improved if the device supplies the termination power. Contact
your device manufacturer for more information on your device’s ability to supply termination
power.

Glossary
Some terms used in the storage industry are defined below. More information is available through the
ATTO Technology website (www.attotech.com) and the SCSI Trade Association (www.scsita.org).
Term Definition
ANSI American National Standards Institute
Asynchronous
Information Protection
AIP: although most Ultra320 traffic is sent synchronously and protected by
CRC, some information is still sent asynchronously. AIP implements CRC-level
error checking on asynchronous traffic ensuring end-to-end data integrity.
Bit Smallest unit of data a computer can process: a single binary digit with a value
of either 0 or 1
Byte An ordered set of 8 bits
CRC
Cyclic Redundancy Checking, an error-correcting code which calculates a
numeric value for received and transmitted data. If no error has occurred during
transmission, the CRC for both received and transmitted data should be the
same.
destination address A value in the frame header of each frame which identifies the port in the node
where the frame is being sent
domain validation Before sending data, domain validation verifies that the physical connection is
capable of handling the negotiated transfer speed. If the system determines that
Ultra320 speeds are not feasible, a slower speed is enforced.
double transition
clocking
Increases the data line frequency to equal that of the request signal, allowing
sampling on both the leading and trailing edges of the request signal. Clocking
can be set to ensure compatibility with legacy devices.
flow control
The target indicates to the initiator when the last packet of a data stream will be
transferred so that the initiator can flush FIFOs and terminate pre-fetch sooner
than previously possible. Basically, the target warns the initiator that the transfer
is almost complete so that it can prepare for the next transfer while the target
completes the current transfer.
host A processor, usually a CPU and memory, which communicates with devices
over an interface
HVD
High voltage differential: uses two wires, transmitting a signal on one and its
inverse on the other. At the receiving end, the difference between the two
signals is measured and interpreted. Noise on the bus will affect both the signal
and its inverse equally, so the difference between the two lines will remain the
same and the noise cannot be misread as a signal.
initiator device A component which originates a command
LED Light-emitting diode: a type of diode that emits light when current passes
through it. Visible LEDs are used as indicator lights on all sorts of electronic
devices.
LVD Low voltage differential. SCSI signaling method that combines the benefits of
HVD and single-ended technologies, allowing longer cabling configurations
while consuming less power than HVD technology.
originator An initiating device; a component which originates a command
packetization
Creates information units (IUs) from commands, data, status information, etc.
which are passed as synchronous transfers. Maximizes bus use, minimizes
command overhead and allows multiple commands to be transferred in a single
connection.

WiebeTech LLC
RedPort SCSI User’s Manual - 8 -
pre-compensation
Although SCSI transfer speeds have changed dramatically over the past
several generations, cable specifications have remained constant. Higher speed
and frequency signals have a greater potential for reflection and distortion over
distance. Pre-compensation techniques slightly modify the SCSI signal to
reduce the chance of these types of problems.
Quick Arbitration
Select (QAS)
Arbitration
The process of devices negotiating for control of the bus with built-in “quiet
times” so that fast and legacy devices have an opportunity to take control of the
bus. A fair, but somewhat inefficient process, QAS speeds up the arbitration
process by eliminating the bus free phase. When combined with packetization,
reduces command overhead and maximizes bus use.
read and write data
streaming
Minimizes data transfer overhead by allowing a target to send one data stream
(LQ) packet followed by multiple data packets. Minimizes overhead of data
transfers because the target can send one data stream packet followed by
multiple data packets.
receiver The ultimate destination of data transmission; a terminal device
SCSI Small Computer Systems Interface: a processor-independent standard for
system-level interface between a computer and intelligent devices including
hard disks, floppy disks, CDROM, printers, scanners, etc.
single-ended An electrical signal protocol that transmits information through changes in
voltage. Single ended SCSI uses standard TTL signal and ground pairs to
transmit information over the SCSI bus.
training pattern
SCSI is a parallel bus technology that is dependent on signals being transmitted
on parallel wires simultaneously. At higher speeds, minute differences in wire
lengths and transmission characteristics could cause problems. Training pattern
testing measures these minute differences and compensates for them.
