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.
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.
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.
