Connecting the LEX unit to the REX unit
To ensure proper operation, it is recommended that only Cat 5 or better, Unshielded Twisted Pair (UTP) cabling
be used to connect the LEX unit to the REX unit. The cabling must have a straight-through conductor
configuration with no crossovers and must be terminated with 8 conductor RJ45 connectors at both ends. The
combined length of any patch cords using stranded conductors must not exceed 10m.
With Surface Cabling
1.
Plug one end of the Cat 5 cabling (not included) into the Link port (RJ45) on the LEX unit.
2.
Plug the other end of the Cat 5 cabling into the Link port (RJ45) on the REX unit.
With Premise Cabling
1.
Plug one end of a Cat 5 patch cord (not included) into the Link port (RJ45) on the LEX unit.
2.
Plug the other end of the patch cord into the Cat 5 information outlet near the host computer.
3.
Plug one end of the second Cat 5 patch cord (not included) into the Link port (RJ45) on the REX unit.
4.
Plug the other end of the 2
nd
patch cord into the Cat 5 information outlet near the USB device.
Checking the Installation

On the LEX and REX units, check that the Power, Host, and Link LEDs are on and that the Activity LED
