Jeti Model Duplex REX12 12 Channel Full Range Receiver with Integrated Expander and UDI Digital Output.

12 channel full-range receiver compatible with JETI EX & EX Bus protocols. Supports telemetry functions and contains a separate battery power connector.

Features

  • PPM input
  • PPM output
  • Integrated expander for EX & EX Bus devices
  • UDI digital output
  • Telemetry compatible
  • Dual receiver antennas

Product Information

JETI Duplex  receivers are designated for use with the DC/DS transmitters or the JETI transmitter modules in the 2.4 GHz frequency band.

The receivers support online updates so that everyone is able to install the latest software versions. From the very beginning bidirectional transmission has been a distinctive feature of the Duplex system, this not only handles telemetry data, but it also helps to ensure secure primarily transmission safety between the transmitter and receiver.

The Duplex EX telemetry system uses an open protocol. This gives the advantage of compatibility with a large number of telemetry sensors from both JETI model and third party producers. For the display of telemetry data you can use purposely designed equipment like the JETIBOX Profi and DC/DS transmitters or you can display the data on PCs.

Multiplex Rx-6-Dr Light M-Link 2.4ghz Receiver, Clearance

6-channel DR receiver 

The small, universal 6-channel receiver in MULTIPLEX 2.4 GHz M-LINK technology. As a dual receiver, it has two complete, parallel-working receive channels (receiver diversity) in spite of the small size, thus ensuring very good reception quality. The RX-6-DR light M-LINK is particularly suitable for smaller models due to its low weight and small dimensions. The inline connector arrangement as well as the compact design allow the use in slim hammers (eg F3B, F3J, ...).

Features

  • HOLD / FAILSAFE function
  • Integrated button and LED for:
  • Binding
  • Program the FAILSAFE
  • RESET
  • Operating status information

Jeti Model Central Box 310

The Central Box is a switchboard designed for the complete management of servos in a model with an emphasis on safety. The Central Box 310 offers maximal unreduced power for each servo (servo outputs do not have overload protection).

Features

  • Adjustable powerful BEC for voltage stabilisation (connection of standard or HV servos)
  • DITEX servo telemetry support
  • Possibility to connect up to 3 receivers with serial communication
  • Built-in Expander function with the possibility of independent connection of up to four JETI EX sensors
  • Input for magnetic switch or RC switch
  • Power supply batteries connected via MPX connector
  • 100Hz mode of servo outputs (10ms period)
  • EX telemetry support (measurement of voltage, current, capacity, temperature, etc.)
  • Easy settings changes via DC/DS transmitter (Device explorer)
  • Robust metal construction with mounting holes

Product Information

The Jeti Central Box 310 is a fully programmable switchboard with two (2) independent, stabilised power inputs with a single voltage regulator (20A Continues/80A Peak) designed for complete power and signal management of servos with great emphasis on safety. The Jeti Central Box 310 and is designed with an aluminium housing for those high power demand applications. Specially designed for models utilising very large servos with high current draws, the overload feature of the Jeti Central Box 320 has been removed. The Jeti Central Box 310 features true Battery Redundancy, Ditex Servo Telemetry, Jeti EX Telemetry, and up to three receiver inputs (2x 2.4GHz and 1x 900MHz) with serial (PPM, EX Bus) output for complete Power & RF Signal Redundancy. In addition, the Central Box 310 has up to four (4) independent E1/E4 telemetry inputs. The onboard BEC allows the output voltage for the servo to be adjusted from 5V to 8.4V in 0.1V steps using the Jeti Transmitter Device Explorer interface.

With Jeti Duplex 2.4GHz DC/DS transmitters, the full potential of the Central Box can be used, such as an easy way to wirelessly configure the Servo Outputs, Ditex Servo & EX Telemetry, Fail-Safe Setting, or Function Assignment.

Power Supply

The power batteries are connected to the Central Box using MPX connectors. The Central Box allows two batteries to be connected. During use, the power is actually supplied from the battery with a higher voltage. If the voltage is the same, the power can be used from both batteries at the same time. When the voltage of the batteries is different, the power is not shared and each pack is isolated from the other. This allows you to use batteries of different capacities, number of cells, and chemistry types. If the power for the Central Box is provided only from one battery, it can be connected via battery (BATT 1) Input.

Magnetic Switch (Optional)

The magnetic switch is used to turn the Central Box ON/OFF and is connected to a separate slot labelled "SW". To turn on the Central Box using the magnetic switch it is necessary to hold the supplied magnet (key) to the target so that the key and the target on the magnetic switch are properly oriented.

Wireless Switch R3/RSW (Included)

A state-of-the-art device that sets Jeti as a leading designer and manufacturer of radio control systems. The wireless power switch is fully integrated into the 2.4GHz radio system. For the first time, your receiver can be turned ON/OFF with simple flipping of the switch wirelessly from the Jeti DC/DS transmitters.

Features

  • Compatible with all Spektrum DSM2 and DSMX transmitters
  • Compact footprint fits most parkflyer size, giant scale and carbon-fiber DLG aircraft installations
  • Features full range telemetry, integrated barometer to provide altitude and vario telemetry data without the need of additional sensors
  • Bind button allows for easy binding and eliminates the use of bind plug
  • Two external antennas will ensure secure RF coverage from all angles of the aircraft
  • Additional RF path redundancy with an additional SRXL2 Remote Receiver (SPM9747, sold separately)
  • Ready to use with Spektrum Smart ESC for one-wire telemetry data without the need of modules, links and wires

Product Information

The Spektrum AR6610T 6-channel receiver is a DSM2 and DSMX compatible receiver with a compact footprint design to fit in a wide range of models. It will deliver lightning-fast input-to-output response that is perfect for high-performance applications such as 3D airplanes and helicopters. It features full range telemetry, integrated barometer to provide altitude and vario telemetry data without additional purchase. An SRXL2 port for an SRXL2 Remote receiver is available separately to eliminate the reflected signal fading and antenna blind spots that can affect 2.4GHz systems. 

The AR6610T receiver throttle port includes SMART Throttle. When equipped with SMART Throttle the normal servo connector delivers the throttle signal to the ESC, plus the ESC can send telemetry data like voltage and current back to the receiver. The AR6610T receiver is compatible with the Spektrum Avian line of ESCs. For SMART Throttle to function you must have a SMART Throttle ESC paired with a SMART Throttle telemetry receiver, and a Spektrum DSMX transmitter with telemetry. An update for your transmitter may be required for Smart Technology features. See www.spektrumrc.com to register and update your transmitter.
