speakercraft Time Controller

[cesarscav]

Hi, all
I'm Helping a friend setting up LinuxMCE on his house, every thing is good so far, the only thing is that he has a speakercraft Time controller (it actually do not control time http://speakercraft.com/#Products:83:TIME%20Controllerthis thing control elevation an rotation of in calling speakers it has a rs232 port and the commands are good documented. I want to create a device template to control some presets, My question are:
What Device Category this will be in?
From where, on a orbiter, the controls will be shown?
it's possible to edit o create command on an orbiter? If so how?
How Do I add or edit the default device Icons on the floor Plan?
 Thanks in advance
