Futaba R7008SB connection

  • i have 2 x Futaba 7008SB receivers i want to connect to a Mercury Powerbox. Usually in a single RX system, i would have the receiver battery connected to port 8. If i set the RX port to SBUS configuration is it ok to use a 3 way splitter so i can still power the receiver, and send a signal to the Mercury RX inputs. If so do i have to use a seperate battery for each receiver as well, to keep electrical isolation between RX1 and RX2.? The manual doesn't have any recommended wiring diagrams.
