(Manufacturing of JLog2 is discontinued by SM-Modellbau, R²prototyping instead provides JLog2.5, which supports further ESCs as virtual multi-sensors. Sources: Links)
Special JIVE logger and telemetry interface
JLog is a special data logger processing the diagnostic data stream of a Kontronik JIVE or Castle Creations ICE/Edgeseries ESC – data of the ESC’s internal sensors and other data of the ESC. The logger stores the output as log files on a microSD card and drives a live stream through an USB interface or telemetry. Plotting of logs is preferably done by LogView.
Unique features are:
- high data capacity, small dimensions, low power requirement
- no data transfer required prior to data evaluation
- no complex cabling
- capturing of data that a native logger can’t provide
- measurement readings not integrated (no rms values) what leads to real-life amplitudes
- configurable alarms – alarms by telemetry and/or alarm lines
- configuration and updating from the SD card
- The logger can be used also without an ESC.)
Differences between JLog2andJLog1
Both loggers are of identical dimensions (“stamp”) but based on different hardware:
JLog2
o connections for additional JLog-own sensors:
• analog temperature sensor or
• upto 5 digital temperature sensors or
• RPM sensor or
• upto 2 alarm lines, also pulsed for LEDs/Luxeons, Morse
• (With a simple D.I.Y. adaptor also temperature sensor(s) and RPM sensor may be connected at the same time, or one type of sensor and an alarm line.)
o live data or telemetry
o 9 instead of 4 alarm types before (v.2.7)
o motor current calculation now more granular at all and more exact in border areas
o floating offset for calibration of values for motor and BEC current
o temperature compensation of the motor shunt in the JIVE as well as recalibration possibility
o calculation of cumulative mAh more precise once again
o now 31 in place of before 13 (respectively 18 with v.2.7) log values in LogView o alternative to configure the logger also without a PC (JLC) by a JETIbox or Unidisplay o besides telemetry also “wired” live data for setup purposes, with the displays JETIbox, SM Unidisplay or Graupner SmartBox o updating the logger is no more individualized and done by a file on the mSD
o Further JLog-own sensors using special firmware (matrix), speed measurement with a pitot head and GPS, Robbe BID Chip, voltage, servo pulse lengths, etc. JLog can also serve as a phase sensor for a governor. Most connections are shown here.
