Smartcontroller vs. S100 Controller

Dear Raymarine:

I have a Raymarine ST-2000 autopilot.
I also have a Raymarine i40 Bidata system.
Both systems are not connected together. Independent of each other.

I want to buy a remote control for the ST-2000 and I see that I have 2 possibilities:

- S100 Controller
- SmartController

I need you to tell me what other connectors or cables I need to buy in order to interconnect these devices, please indicate both possibilities:

Case A: ST-2000 + S100
Case B: ST-2000 + i40 Bidata + SmartController

Thank You!
Pablo
