Introduction

The SEL-3022 incorporates a wireless LAN (WLAN) with which you can perform 
engineer access to IED and diagnostic and maintenance functions. The wireless aspect 
of the device makes connection of the SEL-3022 to a Personal Computer (PC) simple 
and efficient. Make such a connection through use of the SEL-5809 Settings Software 
or SEL-5810 Virtual Serial Software and 802.11b (also known as Wi-Fi) compliant 
devices standard with many new notebook PCs or available at most computer stores.
