Answers
What does
"LEX" and "REX" stand for? What do they do?
LEX stands for Local EXtender.
REX stands for Remote EXtender.
These two units comprise a standard Icron Extension solution.
The LEX unit interfaces to the host PC via a Type-B USB connector.
The LEX interfaces to the REX unit over the extension media
(Cat-5 UTP, Fiber, etc.) and the REX unit provides connectivity
for one or more USB devices at the remote location.
Can I
daisy-chain ExtremeUSB systems together for longer reach?
No, it is not possible to daisy chain multiple ExtremeUSB
systems together. Only a single LEX and REX pair can be connected
to a host PC to ensure proper operation.
Can the
CAT-5 based USB Extenders operate through a standard Ethernet
hub, switch or router?
No. Icron's USB extenders do not use standard Ethernet over
the Cat-5 link and are not compatible with Ethernet hubs,
switches or routers. The link protocol used is proprietary
and operates only as a dedicated point-to-point connection.
What is
the CAT-5 pin out for my product?
Most Icron products use two out of the four pairs in a standard
Cat-5 UTP cable. Icron uses pins 4,5 and 7,8 on the RJ-45
connector. This is a standard straight-through connection.
The Rover 1650 and 2650 units are the only exceptions. Both
of these products use all four pairs of the UTP cable.
How much
power does my extender unit use?
The table below provides details regarding power supply requirements
and power consumption of Icron's products.
What is
the difference between the North America and International
Power Supplies?
The North American (NA) power supply is generally a 2-prong
wall mount adapter for use with North American AC power sockets.
The International power supply is a brick style unit with
a standard IEC C14 socket connector for connection to the
AC mains. Different AC power cords for different regional
AC plugs are included with the International power supply
depending on the specific part number ordered. (AC cables
available include: North American, UK and Europe plugs).
Can I
operate an Icron extender outside the documented temperature
range?
Operation of Icron products outside of the documented maximum
operating conditions is not recommended, and voids the warrantee
of the product. Icron takes no responsibility for damage to
the unit which may occur if used outside of the recommended
operating limits.
Can I
connect a mouse or keyboard to a Rover 1300?
No. The Rover 1300 only supports a single, Full Speed (12Mbps)
USB device such as a webcam, or harddrive. It does not support
Low Speed (1.5Mbps) devices such as keyboards and mice. Additionally,
the Rover 1300 does not support hub connections at the remote
end.
What is
the difference between USB 1.1 Core TP and USB 1.1 Core DL
solutions?
The USB 1.1 Core TP (Twisted Pair) modules provide a small
form factor embedded platform for integration of ExtremeUSB
in OEM applications. The Core TP module provides the physical
layer interface and requires a minimum of 2-pairs of a CAT-5
UTP cable for proper operation.
The USB 1.1 Core DL (Direct Link) modules provide the same
small form factor embedded platform, but offer even greater
application flexibility by removing the physical layer interface
and providing a simple digital interface with which any physical
layer design can implemented. Reference designs for 1-pair
and 2-pair applications are provided with the modules.
What
is the difference between MTRJ male and MTRJ female connectors?
Which one does the Ranger 422 need?
The Ranger 422 requires fiber optic cable to be terminated
with an MTRJ female connector. Most fiber manufacturers will
make female MTRJ connectors if the gender is not specified.
Male connectors are used only in patch panel applications
where two fibers are joined through a connecting socket. The
MTRJ male connectors have two small studs protruding from
the front of the connector. These studs mate with the holes
in the female connector to align the fiber optic cables inside
the MTRJ connector.
Is ExtremeUSB
2.0 backwards compatible to support USB 1.1 devices?
Yes, a Low Speed or Full Speed USB device will operate with
ExtremeUSB 2.0, however, the ExtremeUSB 2.0 device (Ranger
140/440/442/444 or Core 2.0 DL) must be connected to a USB
2.0 Host Controller. ExtremeUSB 2.0 will not function if connected
to a USB 1.1 host.
What
does the "G" mean on the Icron part number?
The G on the Icron part numbers has been recently added to
indicate that the product is RoHS Compliant. Click here
for further information regarding RoHS Compliance for Icron
products.
Is my
Icron product EN60601 Medically certified?
Icron products are not EN60601 certified.
Who
do I contact if I think my Icron product is defective?
Please contact your point of sale regarding the return of
defective products. If you require debugging assistance in
deterimining if the unit is defective, contact Icron Technical
Support at techsupport@icron.com.
How
can I get the firmware on my Icron product upgraded?
To upgrade the Ranger 110, 410, 422, Core/TP or Core/DL products
please contact Icron Technical Support at techsupport@icron.com
and Icron will be able to ship you new PROMs with the latest
firmware (where applicable).
To upgrade the USB 2.0 Ranger 140, 440, 442, 444 or 2.0 Core/DL
products please contact Icron Technical Support at techsupport@icron.com.
To upgrade these products, the units must either be returned
to Icron to re-flash the program memory, or a Xilinx JTAG
programming cable (either the Parallel Cable IV or the Platform
Cable USB) will be required to perform the upgrade on site.
There are no upgrades available for the Rover 1300, 1650 or
2650 products.
Are
there known USB device incompatibilities with my WiRanger
system?
The WiRanger complies with USB 2.0 specifications governing
the design of high-speed USB devices. However, because of
the data rate limitations inherent in the IEEE 802.11g radio
platform, Icron Technologies Corporation does not guarantee
that all USB devices are compatible with the WiRanger.
Webcams that use the BULK transfer protocol are not supported.
This limitation is due to the restricted bandwidth available
over the 802.11g channel on the WiRanger system. NOTE: This
restriction does not apply to Isochronous Web Cameras. These
devices function normally with the WiRanger.
What is the USB device limit for your USB 2.0 extenders?
Our USB 2.0 extenders have a maximum limit of 14 devices connected to the REX unit (including USB hubs).
What does a blinking REX LINK LED for USB 2.0 extenders mean?
The USB 2.0 extender is in suspend mode. Windows XP will put hubs in suspend mode when no USB devices are connected to the USB hub. The hub will wake-up from suspend mode when a USB device is connected.
The Ranger 110/410 REX and LEX both have sockets for power supplies, do I need power supplies for both units?
Only connect one power supply to either the Ranger 110/410 REX or LEX unit as there is no benefit to having a power supply attached to both REX or LEX unit. Please see the user manual for details.
Are Icron's products compatible with my Operating system?
Any Operating system that supports the required Icron Ranger USB specification requirements in full and includes the use of USB hubs via operating system vendor supplied drivers is supported by Icron's products. We perform testing on many platforms to ensure product reliability and performance.
