JetCat Turbine Telemetry System for DMSS
£39.95
Tax Included
This telemetry unit will take data from your JetCat ECU and relay it to your JR DMSS radio. Please note that the data which is relayed back to your radio may not be 100% accurate and should be used as a guide.
Please plug the supplied JetCat style lead into the telemetry device and either the data port on your JetCat ECU or the plug on the I/O board. Then plug the supplied male-male patch lead into the other end of the telemetry device noting the polarity with the other end of this lead into either the data port on your JR DMSS receiver or into you TLS1-ADP (sold separately).
You will need to configure the telemetry screen on your JR DMSS radio. Please refer to the radios manual on how to do this.
Several different turbine parameters can be monitored including;
| Parameter | Radio Telemetry Setting |
|---|---|
| Turbine RPM | RPM |
| Turbine Exhaust Gas Temperature (EGT) | Temp |
| Turbine Status | FPACK Watts* |
| Last Shutdown Code | FPACK Watts* |
| EUC Battery Voltage | FPACK Voltage |
| Current Fuel Flow | FPACK Current |
| MI Consumed/Remaining | FPACK.mah** |
* Please see the table below for status and shutdown codes
** The fuel tank size will need to be configured on both the transmitter and the ECU. For the transmitter set the battery capacity to your fuel tank size (measure in ml), for the ECU follow the calibration instructions in the JetCat manual.
Turbine Status
