2. Q: Sometimes the system takes longer to connect and sometimes it doesn’t connect
at all?
A: In order for the system to connect (after the receiver is bound) the receiver must receive a large
number of consecutive uninterrupted perfect packets from the transmitter. This process is
purposely critical of the environment ensuring that it’s safe to fly when the system does connect.
If the transmitter is too close to the receiver (less than 4 ft) or if the transmitter is located near
metal objects (metal TX case, the bed of a truck, the top of a metal work bench, etc.) connection
will take longer and in some cases connection will not occur as the system is receiving reflected
2.4GHz energy from itself and is interpreting this as unfriendly noise. Moving the system away
from metal objects or moving the transmitter away from the receiver and powering the system
again will cause a connection to occur. This only happens during the initial connection. Once
connected the system is locked-in and should a loss of signal occur (failsafe) the system
connects immediately (4ms) when signal is regained.
3. Q: I’ve heard that the DSM system is less tolerant of low voltage. Is that correct?
A: All DSM receivers have an operational voltage range of 3.5 to 9 volts. With most systems this is
not a problem as in fact most servos cease to operate at around 3.8 volts. When using multiple
high-current draw servos with a single or inadequate battery/power source, heavy momentary
loads can cause the voltage to dip below this 3.5-volt threshold thus causing the entire system
(servos and receiver) to brown out. When the voltage drops below the low voltage threshold
(3.5 volts), the DSM receiver must reboot (go through the startup process of scanning the band
and finding the transmitter) and this can take several seconds. Please read the receiver power
requirement section as this explains how to test for and prevent this occurrence.
4. Q: Sometimes my receiver loses its bind and won’t connect requiring rebinding.
What happens if the bind is lost in flight?
A: The receiver will never lose its bind unless it’s instructed to. It’s important to understand that
during the binding process the receiver not only learns the GUID (code) of the transmitter but
the transmitter learns and stores the type of receiver that it’s bound to. If the transmitter is placed
into bind mode, the transmitter looks for the binding protocol signal from a receiver. If no signal
is present, the transmitter no longer has the correct information to connect to a specific receiver
and in essence the transmitter has been “unbound” from the receiver. We’ve had several DX7
customers that use transmitter stands or trays that unknowingly depress the bind button and the
system is then turned on losing the necessary information to allow the connection to take place.
We’ve also had DX7 customers that didn’t fully understand the range test process and pushed the
bind button before turning on the transmitter also causing the system to “lose its bind.”
