The Econet module for the A3020 and A4000 is very similar to its predecessor, the ADF10 Econet Module which was introduced with the Master. The main differences are that the module is a bit smaller and has shorter legs, this is so that it fits underneath a mini-podule. This module will work in a Master and vice versa.
Here are the A3020/A4000 Econet Installation instructions .
