Diversity antennas
The SPM4648 incorporates two diversity antennas. Each antenna includes
a coaxial portion (which can be thought of as an extension) and an exposed
31mm tip antenna. The last 31mm is the active portion of the antenna. Do not
allow the antennas to kink and never cut the antennas.
installation
Mount the antennas 90° off from each other so one is vertically polarized and
the other horizontally polarized. Chose a location so that at least one antenna
will always be in the RF visual line of sight of the transmitter (e.g. not blocked
by carbon fiber, aluminum, etc.) in all attitudes.
autobind
1.
With the transmitter off, power on the receiver.
2.
The receiver will attempt to connect to the last transmitter it was bound to.
3.
If no transmitter is found it will enter Bind mode, as indicated by a flashing
orange LED.
4.
Turn on your transmitter and allow the remote receiver to autobind.
5.
When the receiver binds the orange LED turns solid.
iMPoRtant:
Once the receiver is bound to your transmitter, always
power your transmitter on first so the receiver will not enter bind mode. If
the model enters bind mode unintentionally, shut off power to the model,
ensure the transmitter is powered on with the correct model selected, and
then power the model on again. The receiver will not lose its previous bind
information if it enters bind mode and does not bind.
failsafe
The SPM4648 does not have failsafe capabilities, failsafe should be detected at
the flight controller. Always ensure your flight controller is properly configured to
power off the motors in the event of an RF loss.
