S.bus Servo - FUTABA 7XC Instruction Manual

This is a special function which allows Futaba S.BUS/S.BUS2 servo parameter changes to
be set by the T7XC transmitter. However, some data changes require a PC and S-Link soft-
ware. There are two ways of setting wired to connect the servo directly to the com port of
the transmitter and wireless to set the servo as it is connected to the receiver. When setting
with wires, please use optional extension cord for servo as necessary. (The SR mode setting
is a dedicated parameter from the transmitter, it cannot be set with the S-Link software.)
Also, please read below " Notes " as there are restrictions in wireless setting.
Note:
-If shutting off while writing the parameters, the servo may fail. Please use this function
with suf昀椀cient battery power.
- For safety reasons, it is not possible to change between normal mode and SR mode
with wireless setting. To change the mode, connect the servo to the communication (com)
port and switch. However, for servos set to SR mode, SR1 / SR2 / SR3 can be switched
by wireless setting.
- Wireless setting cannot be used if a device that converts signals such as gyro and FSU
(Failsafe Unit) etc. are connected between the receiver and the servo.
-A receiver compatible with the wireless setting function is required. At the time of May
2018, software of R334SBS / R334SBS-E version 2.0 or later supports wireless setting.
You can check the receiver version on the receiver setting screen on page 35 and 36.
Please update the version of R334SBS / R334SBS-E before 2.0. )
-Power is supplied to the servo from the transmitter, but the corresponding voltage is for
high voltage servo (HV) use. Since an overvoltage will be applied to servos other than
this, connect the corresponding battery to the servo. When the battery is connected, the
supply of power from the transmitter automatically stops.
Warning
In the wireless setting, there is a danger that a car (boat) can become unexpectedly
uncontrollable, because the servo temporarily stops working during communication. For safety,
in case of electric car (boat), please set with driving wheel (boat propeller) not touching the road
surface (water surface). Also, in the case of an internal combustion engine car (boat), be sure to
stop the engine before entering wireless set-up mode.
Caution
When connecting an S-BUS servo that does not support high voltage, connect a battery matched
to the servo specifications.
High voltage servo support voltage is supplied from the transmitter. If a servo that does not support high voltage is con-
nected, unreasonable force will be applied to the servo and will cause trouble.
Do not disconnect the servo connector or turn off the transmitter power while writing parameters.
It may cause the servo to malfunction.
