Failsafe Mode Drives All
Channels
to Preprogrammed
Positions
Spektrum has announced a specially-programmed
receiver configured for combat robots in all classes. Spektrum’s BR6000 receiver is designed for robot and special application usage where it’s desirable to have the failsafe drive all channels to a preprogrammed position during loss of signal (as opposed to a failsafe default that holds the last command). This is ideal for applications where it’s necessary to shut down systems (ie. weaponry, drive motors, etc.) during loss of signal to prevent an unsafe condition.
FREE REPLACEMENT OF AR6000 RECEIVERS
If you currently own a DX6 radio and are using it in a robot application, you’ll want the new BR6000 receiver. You can order SPM6000BR from www.horizonhobby.com or you can return your AR6000 receiver and we will exchange it for a BR6000. Send the AR6000 receiver to Spektrum Service, 4105 Fieldstone Road, Champaign, IL 61822. Please include your name and address. We will quickly send out the BR6000 receiver in return!

BREAKTHROUGH SPEKTRUM DX6 ROBOT RADIO
Retailing for just $200, the 6-channel programmable Spektrum DX6 radio system is a revolutionary advance for robot enthusiasts. The DX6 eliminates the need for frequency control and provides interference-free operation with an rf link that is redundant and rock-solid. If all robot drivers at a combat event are using the DX6, up to 40 robots can be operated simultaneously! The Spektrum DX6 system can be turned on anywhere, any time, without concern for interference or the operation of other robots nearby. You can forget about frequency control pins, waiting until someone gives up your channel, or impounding your radio. Gone are concerns about changing crystals of finding a screwdriver for your synthesizing module.
The DX6 utilizes DSM™ Digital Spread Spectrum Modulation to ensure a rock solid connection between you and your robot. Unlike frequency hopping modulation used in some 2.4Ghz applications, DSM operates statically within the band to maximize reliability and efficiency. When you first power up the DX6 transmitter, it scans the 80-channel 2.4Ghz band before beginning to transmit any signal. When it finds an open channel, it locks onto it and starts transmitting to prevent another radio from also selecting that channel. The DX6 then continues scanning.
The DX6 operates on two frequencies simultaneously. After the transmitter locks onto a second channel your link is solid until you turn it off. Finding and locking up these two channels typically only takes about 5 seconds. This DuaLink™ technology means you have redundant parallel control sequences communicating with the receiver. The receiver is actually two separate receivers in one compact package, hence the two antennas. If the band is saturated with 40 other modelers, the transmitter will continue to scan until someone else shuts off.
In addition to transmitting control sequences, the DX6 transmitter also broadcasts its own Globally Unique Identifier, or GUID. It is this “fingerprint” or “key” if you will, that ensures a bullet-proof connection between your transmitter and receiver. The receiver is “bound” to the GUID before initial operation, and locks onto it when powered up. There are 4.2 billion GUIDs available so the odds of two identically keyed transmitters showing up at the same robot contest at the same time are pretty slim.
Operational protocol for the 2.4Ghz band is carefully defined by international agreement to prevent interference between devices. The DX6 will not transmit on a channel already in use by another unit within its scanning range.
Combat robots can generate significant amounts of internal RF noise, but that is no longer a concern with the DX6. Noise generated by electric motors, rattling metal parts, or long servo leads occurs below 300MHz. Operating at 2.4Ghz the BR6000 receiver is immune to such interference. With the DX6 you will not need to solder noise suppression capacitors to brushed motors. The BR6000 delivers exceptional performance for a 7-gram receiver and we have experienced glitch-free operation at distances of well over 1,000 feet between transmitter and receiver.
