3.7. Setting the receiver system
Caution:
Please ensure that you have set the correct receiver type before
connecting the receivers. This is important, because the Spektrum
system operates on only 3.3V, whereas all other receivers work on 5.9V
or 7.4V. For example, if you set the receiver system to Futaba and
connect a Spektrum Remote Receiver, the Spektrum Remote
Receivers will be ruined!
If this setting is not selected, the subsequent functions, settings and
assistants only work in a restricted manner.
Switch the PowerBox on as described above. Hold the Set button
pressed in for a few seconds, and the menu system appears. Select the
RX/TX SETTINGS point; the first point in the TX-SYSTEM menu
enables you to select your radio control system:
• Spektrum DSM2 and DSMX:
If you select Spektrum DSM2 or DSMX, the additional menu point BIND
now appears. Whether you select the DSM2 or DSMX option depends
on your transmitter type - not on the satellites connected to the system.
For example, if your transmitter operates on DSM2, but the satellites
are DSMX types, select DSM2 at this point (for example, this applies to
all Spektrum modules fitted to MC-24 transmitters).
Now connect your satellites, and select the BIND menu point; at least
three satellites must be connected. Even if two of three satellites were
to fail in flight, SRS technology allows the PowerBox to continue to
function correctly with just a single satellite.
All satellites connected to the system now flash, and can be bound to
the transmitter.
