external probe value. As shown, the RMP sensor uses the red wire that is included with the
temperature sensor, but not connected to it.
LED Signals on the Telemetry Unit
Red LED
Solid = Correct data exchange with receiver. This means the telemetry unit is recognizing the
transmitter
and has transferred the telemetry packet to the transmitter for display.
Flashing rapidly = The receiver is in bind mode.
Absent = No connection
Green LED
Solid = The Current sensor initialized correctly when using the hidden pot/switch. The Red LED will
light
up if initialization fails (see page 8).
Flashing = The altimeter is set to provide height above ground level (AGL) data (the default). The
green
LED also flashes while binding.
Absent = The altimeter is set to absolute barometric height (ASL) based on standard 101.325kPa as
sealevel
atmospheric pressure.
[In addition green and red flashes are used as confirmations during user calibration of Current and Voltage.. A
single quick flash of the green LED at power up identifies versions of the telemetry unit v1.5 and beyond.]
For most users a solid red LED and a flashing green LED indicate correct
operation.
Detailed information about the Hyperion Telemetry Unit
The Hyperion Telemetry unit is not a copy of anything made by Spektrum™, but an original design
that
conforms to the Spektrum™ data transmission protocol and the DSM2™/DSMX™ radio protocols.
The Hyperion unit differs from the Spektrum™ TM1000 telemetry unit; both in construction and in the
way it provides certain data. Most obvious is that there is no display of the Fields H and F (Holds and
Frame loss), nor are there packet loss indicators for the four possible receivers: A, B, L and R.
These features are unique to Spektrum™ systems. In their place Hyperion provide a general “Signal
Indicator”, displayed in the “A” field that provides roughly similar data on the strength and reliability of
the radio link. The unit is significantly smaller than the Spektrum™ one and about half the weight. It
operates over an input voltage range of 3.45 to 7.2v. (Despite the “5.5V max” written on the label.)
Specifics
The Hyperion Telemetry unit uses an ATmega 88PA microprocessor and a 2.4Ghz transmitter to
send data signals to your transmitter. It synchronizes with the receiver via the bind connector so that
it cannot interfere with the radio control link. It reads the receiver voltage and the number of data
packets successfully arriving at the receiver, combines those with its own data from sensors, and
sends the whole lot to be displayed on the transmitter telemetry screen. Without any additional
sensors it will display receiver voltage (RxV), signal indicator (A), accurate height above ground level
(Alt), and the internal temperature of the unit (Temp). The unit is supplied with two plug-in sensors.
The first is an accurate external temperature probe, which automatically replaces the internal
temperature when connected and can be used to monitor LiPo pack or ESC temperature in flight.
The external temperature sensor also includes a sensor wire for measuring RPM from one of the
motor wires. Before using the RPM function, please review its limitations, as discussed on page 7.
