- 25 -- 24 -How to use Digital key pad (option)Parameter copy functionParameter copy function (Digital key pad ←→ Brushless amplifier) can be used by Pr77.• Initializing the data of the Digital key padEEPROM installed onboard the Digitalkey pad is initialized (data cleared).When reading is disabled, or when datatransfer fails during copying, execute“Data initialization of the Digital key pad”.Normally, it is not required.• Reading parametersParameter of Brushless amplifier is read and saved in EEPROM of the Digital key pad.Read parameter is retained even when the Digital key pad is separated from the Brush-less amplifier.• Writing parametersParameter information saved in the Digital key pad is written to the Brushless amplifier.(Saved in EEPROM of Brushless amplifier)• Error in copying parameters: Data trouble was found during copying→ Press switch for clearing, and then copy the parameter again. If data trouble isstill found, initialize the Digital key pad and try again.: Copy error→ This error occurs in the attempt to copy data between products with different function.Press switch to cancel the error.Although parameters can be copied between the same models with different output,parameters should be copied between the same outputs in principle.Do not turn off power or disconnect the connection cable of Digital key pad during opera-tion such as “Initializing data of Digital key pad”, “Reading parameter into Digital key pad”,“Writing parameter to brushless amplifier”, etc.All flashingon displayData initializationof Digital key padNormal conditionParameter reading(Amplifier Digital key pad)Parameter writing(Digital key pad Amplifier)Hold down(for about1 second).Press both atthe same time.For about30 secondsAll flashingon display For about30 secondsAll flashingon displayFor about10 secondsAll flashingon displayHold down(for about1 second).Hold down(for about1 second).Processcompleted ProcesscompletedTrip resetProcesscompletedParameters that areeffective after powerresetting becomeeffective when poweris cut off once andturned on again.
