The AR9020 9-Channel DSMX Receiver from Spektrum is a full-range, 9-channel receiver for your RC aircraft. It is compatible with all Spektrum and JR DSM2 and DSMX transmitters, and gives you the option of adding extra channels by plugging the optional X-Plus 8-channel expander into its SRXL port. It features a fast input-to-output response with an 11ms frame rate when used with capable Spektrum transmitters, 2048 resolution, and one internal and two remote receivers for RF redundancy. Additionally, it provides advanced features to help keep your aircraft safe, such as SmartSafe failsafe and QuickConnect. The receiver is also telemetry compatible and supports Spektrum's optional Flight Log module for tracking RF link performance.
Important: The AR9020 is not for use in airplanes that have full carbon fuselages or that have significant carbon or conductive structures.
Note: The AR9020 receiver is not compatible with the DX6 parkflyer transmitter.
Full-Range 2.4GHz DSMX Receiver
DSMX operates on the 2.4GHz band and combines superior data capacity and interference resistance of a wideband signal with the agility of frequency shifts. This makes DSMX less likely to suffer significant data loss from on-channel interference, resulting is quicker connection times and superior response in crowded 2.4GHz environments. DSMX technology is active only when both transmitter and receiver are DSMX enabled. The AR9020 will also work with existing DSM2 enabled transmitters.
MultiLink Receiver Technology
The AR9020 features three receivers, offering the security of multiple path RF redundancy. An internal receiver is located on the main receiver while two required external receivers are attached to the main board with a 6" and 12" extension. You can also add an optional fourth receiver for further RF redundancy and security. Locating the receivers in slightly different locations in the aircraft exposes each receiver to its open RF environment. This greatly improves the receivers' ability to see the signal in all conditions.
With SmartSafe, when your RF signal is lost the throttle channel only is driven to its preset failsafe position (normally low throttle) while all other channels hold last command. It also prevents unintentional electric motor response and the possibility of over-driving servos on start-up by storing preset failsafe positions.
The AR2020 gives you the option of adding extra channels by plugging an optional X-Plus 8-channel expander into its SRXL port. Use the extra channels to enhance the realism of your scale models by adding working accessories and lights, in addition to regular control functions.
QuickConnect with Brownout Detection
Should an interruption of power occur, known as a brownout, the system will reconnect immediately thanks to QuickConnect technology. The LED on the receiver will flash slowly, indicating that a power interruption has occurred. A power interruption occurs when the receiver voltage drops below 3.5 volts. When power is restored, the receiver attempts to reconnect to the last two frequencies that it was connected to. If the two frequencies are present the system typically reconnects within one second.
Note: While DSMX receivers have QuickConnect technology and recover instantly from a power interruption, the architecture of DSMX prevents Brownout Detection when operating in DSMX mode. Brownout Detection is only available in DSM2 mode.
The AR9020 supports ModelMatch, which is offered on some Spektrum and JR transmitters. ModelMatch prevents the possibility of operating a model using the wrong model memory, potentially preventing a crash. With ModelMatch, each model memory has its own unique code (GUID) and, during the binding process, the code is programmed into the receiver. Later, when the system is turned on, the receiver will only connect to the transmitter if the corresponding model memory is programmed onscreen.
