F Rate (Frame Rate)
Frame rate is the response
rate of the receiver. The lower
the number, the faster the
response. Frame rate only
affects the current model.
IMPORTANT: You should always use the fastest response
rate the servos can handle. This gives the lowest latency and
fastest response. If the frame rate is incompatible with the
servo, the servo will move erratically or in some cases not at
all. If this occurs, change the frame rate to the next highest
value.
The available frame rates will depend on the type of receiver the
DX4S is bound to:
DSMR: 11 or 22ms DSM ® : 11 or 16.5ms
DSM2 ® : 11 or 16.5ms Marine: 22ms
1. Use the roller to highlight the F Rate function.
2. Press the roller.
3. Rotate the roller to select the frame rate and press the roller
to save the selection.
RF Mode
You can set this mode on either Std or FR. Std is the standard
RF mode. FR is the France RF mode and should only be selected
when the transmitter is used in France outdoors. RF mode af-
fects all models.
RS Port
This sets the port – (Bind or Aux (Auxiliary) – on the receiver for
ROSS (Remote Onboard Starting System) connection. RS Port is
model specifi c.
