R6303SBFASST-2.4GHz (7ch/8ch/10ch/Multi-ch) system
S.BUS port and 3 channels for conventional system
High-Speed receiverThank you for purchasing a Futaba R6303SB FASST-2.4GHz receiver.
The R6303SB has an S.BUS system output port and 3 conventional
system channel outputs. It can also be used with conventional systemservos, etc. in addition to S.BUS system compatible servos and gyros,etc. When the linking procedure is performed, R6303SB recognizes thesignal mode (FASST-2.4GHz 7ch mode or 8ch/10ch/Multi-ch mode)
automatically.
The R6303SB can change the output CH from seven groups (CH grouptable).
In addition, the operating mode (high-speed mode/normal mode) can beselected.

Usage condition for conventional system output(Ch1-3) on "High Speed mode"￼ CAUTION"High Speed mode" accept the digital servos only or￸ Themost type of peripherals.
s )F AN ANALOG SERVO IS CONNECTED TO THESE OUTPUTS IT WILL CAUSE A
MALFUNCTION 0LEASE CHECK THE PERIPHERALS IF THERE IS A MALFUNCTION FULLSTICK MOVEMENT )F THERE IS A MALFUNCTION CHANGE THE RECEIVER BACK TO"Normal mode."

Applicable systems: FASST-2.4GHz 7ch or 8ch/10ch/Multi-ch system

What is S.BUS?
S.BUS is different from conventional radio control systems in that it
uses data communication to transmit control signals from the receiverto a servo, gyro, or other S.BUS compatible devices. The S.BUS
devices only execute only those comands for there own set channel.
This is why a single signal can be used to connect multiple servos.

When S.BUS is used
* Set the channel of S.BUS SERVOS BY USING AN SBC-1 CHANNEL CHANGER CIU-253" SERIAL INTERFACE OR THE PROGRAMMING SOFTWARE IN THE 18MZ transmitter.
