I make standard cables, male on both ends.. The HM has a CAT5 jack and my Roto Damper also has a CAT5 jack, they mate together with the cable. You can get a CAT5 Jack at Home Depot for $3 for the grill end, or wire it up any way you choose really...
Gotcha, make sense now. You could go one step further and purchase shielded CAT5 or CAT6 cable for the ground reference but I think this is not ideal from the previous posts in the forums.
