USBserialinterfaceortheprogrammingsoftwareinthe18MZ transmitter.
* Can also be used together with conventional servos. However, conventional
servos cannot be used by the S.BUS output.
* When using servos with a remote battery pack, use S.BUS Hub with Cable
(2-way/remote battery pack use).
Please refer to the instruction manual of S.BUS Hub with Cable (2-way/re-
mote battery pack use) for the connection method.
*Turn on the power in transmitter→receiver order. In addition, always check
the operation of all the servos before ight.
*Do not insert or remove the servo connector while the receiver power is ON.
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 receiver
to 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.
