1. LE590-TAP Overview
For LE-590TX, all data streams between two network ports can be duplicated and sent to PC via
mini USB port for monitoring and analyzing. The user can specify conditions to filter the packets
wanted with LE590-TAP application software. It reduces USB port’s network traffic and also cuts
down PC resource consumption while dealing with large quantity of packets.
1.1. Hardware Installation
Before starting LE590-TAP, your PC and LE-590TX shall be connected properly. The figure down
below illustrates connecting PC and LE-590TX. You can connect LE-590TX with PC in the same
manner.

If your PC is not connected with LE-590TX, you can still run LE590-TAP under Demo Mode. Almost all
LE590-TAP’s functions are available under Demo Mode. However, please note that Demo Mode is for
system demo purposes only, and does not serve any testing purposes at all.
When your PC cannot detect your LE-590TX, a window as shown above will pop up asking if you want to
start the LE590-TAP in Demo mode or not, also a third option will pop up asking if you want to re-install
WinPcap for successfully run the LE590-TAP.
