SEL-2890 Instruction Manual

Appendix D

Alitree Applet

Introduction

The Alitree applet is written by APC Software Ltd. Java 1.0 is the code behind Alitree.
This should enable the program to be run on older browsers. The supporting
documentation is contained in the file alitree.zip located in the SEL-2890. FTP the
alitree.zip file out of the transceiver and unzip. Instructions on how to pass parameters
are contained in the file alitree.txt.
