Let's Control It

Hello,

I have few questions about 433 and 868 cabling:

1. As I'm using Jeedom, the rflink module can support only ONE rflink module, and so I would like to know if I can plug in parallel 433/868 emitter/receiver to only one MEGA board ?
2. How RFlink firmware know about frequency connected to it (when only one frequency used) ?
3. is there updates schemas for wiring 433, 868 modules ?

Thanks in advance for answering,
Best regards
