Serial Expander v2
The RC Light Systems Serial Expander provides a simple way to access additional channels from your receiver. The Serial Expander connects to your receiver using a serial link such as SRXL, P2Bus and SBus to name a few.
The Serial Expander has 4 servo outputs which can be assigned to any of the channels available in the serial link from the receiver.
The Serial Expander supports the following serial links:
- SBus – Futaba / FrSky
- XBus – JR/DFA
- SRXL – Spektrum
- ExBus – Jeti
- P2Bus – PowerBox Core
- SRXL2 – Spektrum SMART RX
If using PowerBox Core, Jeti, or JR/DFA radios the Serial Expander can be configured from the radio. In XBus mode the Serial Expander looks like a CV4 XBus expander unit (providing mid and end point matching and channel reversing features).
