JETI model s.r.o.

DUPLEX Rsat 900 MHz

DUPLEX Rsat 900 MHz
Art. No.:


The system is continuously improved. Thanks to online updates the improvements are easily accessible to users from any part of the world. 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.

Backup receiver compatible with JETI EX 900 & EX Bus protocols. Supports telemetry functions.

Additional features:

  • PPM input
  • PPM output
  • Integrated expander for EX & EX Bus devices
  • UDI digital output

JETI RSAT 900 receivers are designated for use with the DC/DS-24 transmitters in the 900MHz frequency band.
