Introduction The “Raven 2 PRO” is one component of RC Electronics model aircraft telemetry system. The unit is the “on-board” unit intended to be used with the “Snipe / Finch” “ground station”. The unit is designed to measure many parameters of an R/C model aircraft and transmit them to the ground station via the telemetry link working on 433 MHz frequency.
Physical overview Pictures bellow are showing the Raven 2 PRO unit. It has one SMA connectors for active GPS antenna, 3 pressure ports (Ptot – total pressure, Pst – static pressure, Pte – total energy compensated pressure from TEK probe) and a multi-color LED to show the status of the unit. It also has 3 connectors. The micro USB is used for future updates, settings and flight log download.

SMA connector for GPS antenna There are 2 ways of connection Pte port: 1: When using normal TEK probe, connect it Multi color LED to Pte port and vario will be calculated from measuring compensated pressure at TEK probe. Connect IAS probe to Ptot. IAS 2: When using electronic compensation probe can be mounted in nose or connect Pte port to Pst port.
Using the Raven 2 PRO module Powering the module To power the module plug the 3 pin female connector cable into servo connector and the other end to the R/C aircraft receiver. Be sure to observe proper polarity when plugging the connector into the module and receiver.

Static tube installation In order to utilize the full capability of the Raven 2 PRO an Indicated Airspeed (IAS) probe must be install in the aircraft. The IAS probe must have two components, Ptot (total air pressure) and Pst (Static Air pressure).
Raven 2 PRO. When connected to the PC the module will power up and will create a new Virtual COM port. Run RC electronics device tool software (published on our website under Download / Software section) Select correct COM port and then press select.
Modes of operations Electronic compensation Electronic compensation can work only when an IAS probe (Indicated Airspeed) is installed in aircraft and connected to Raven 2 PRO. It is used when the user wishes to fine tune the TEK probe (TEK probe can be over or under compensating dynamic change of plane).
