With this small, powerful RC data logger and telemetry sensor, you can measure and store voltage, current, altitude, power, capacity, RPM, temperature, and individual cell voltage in a model aircraft, and then conveniently review the data on-site using our UniDisplay or later on a PC or laptop. Full support for telemetry from Jeti Duplex, Multiplex M-Link, Graupner HoTT, Futaba, JR DMSS, FrSky, Spektrum (via Spektrum adapter), and PowerBox Core.

The small, powerful RC data logger and telemetry sensor records and transmits V / A / W / mAh / Wmin / rpm / °C / individual cells / altitude / vario

The UniLog 2 is the successor to our successful UniLog data logger. All familiar UniLog functions have been retained and updated with the latest technology. Numerous new features have been added, leaving virtually nothing to be desired.

Telemetry via 2.4 GHz systems with a return channel is now a standard feature of the UniLog 2 and fully integrated. In line with our philosophy of supporting as many systems as possible, the UniLog 2 also supports Jeti Duplex, Multiplex M-Link, Graupner HoTT, Futaba, JR DMSS, FrSky, and Spektrum (via a Spektrum adapter).

The telemetry system used only needs to be specified once in the UniLog 2 settings. This can be done either via our PC program "UniLog 2 Tool" or with the UniDisplay. HoTT GAM is selected by default.

Since an additional high-resolution barometric (air pressure) altitude sensor is also integrated, a vario is implemented with the UniLog 2 in telemetry mode. Extensive alarms can also be programmed, which are reported via telemetry through the respective transmitter.

When operating with Multiplex M-Link, all data on the sensor bus is automatically logged by the UniLog 2 and also written to the memory card. This effectively provides you with an MSB data logger as well.

A micro-SD memory card serves as virtually unlimited storage for the UniLog 2.

With a recording rate of up to 20 Hz and the micro SD memory card, recordings of almost any length with high resolution are possible. Data transfer to a PC for analysis is also incredibly simple: remove the memory card from the UniLog 2 and insert it into a USB port on the PC using the included card reader. The UniLog 2’s measurement values are stored as text files on the memory card. The data is then displayed and analyzed using the familiar LogView software or GNU DataExplorer. Thanks to the internal real-time clock with battery, all measurement values are always stamped with the date and time.

Another new feature is the ability to measure individual cell voltages. A LiPo battery up to 6S can be connected directly to the UniLog 2 using its balancer connector; the individual voltages are measured and recorded, and of course transmitted via telemetry.

Via our UniDisplay, all UniLog 2 measurement values can also be viewed live, and the recorded data can be read from the memory card. Minimum and maximum values can be quickly retrieved from the stored records and displayed. All settings and alarms can, of course, also be conveniently programmed via the UniDisplay.

Whether it’s a glider, aerobatic plane, helicopter, HLG, or slow flyer, the UniLog 2 can be used in virtually any application thanks to its low weight and compact size. Of course, the UniLog 2 isn’t just suitable for model aircraft. It can also be installed in RC boats, RC cars, and more.

With the UniLog 2, you are purchasing a high-performance, universal RC data logger and telemetry sensor that leverages the capabilities of modern electronics to serve as a small yet invaluable assistant in managing your RC models.

And here’s what the UniLog 2 can do:

• Complete monitoring of electric motors with current, voltage, power, capacitance, RPM, and temperature measurements (current, RPM, and temperature sensors are available separately in various versions)
• microSD memory card
• virtually unlimited recording and easy data retrieval
• Full telemetry support for Jeti Duplex, Multiplex M-Link, Graupner HoTT, Futaba, JR DMSS, FrSky, Spektrum (via Spektrum adapter), and PowerBox Core, including barometric altimeter
• Internal real-time clock (with battery life of at least 5 years)
• All measurements are stamped with a real-time timestamp, i.e., date and time
• Sampling rates from 1 measurement per second (1 Hz) to 20 measurements per second (20 Hz)
• All UniLog sensors can continue to be used
• Balancer connection for LiPo single-cell measurement up to 6s
• Altitude measurement with automatic zeroing after power-on
• Current measurement range up to 400 A and voltage up to 60 V, depending on the connected sensor
• Pluggable current and voltage sensors (making it very small and lightweight when used as a pure altimeter/vario, e.g., in gliders)
• Connection for receiver signal (Rx) and signal output to the ESC
• Universal connections for external speed sensor and up to three temperature sensors
• Temperature measurement also possible with PT1000 sensors for an extended measurement range
• Connection for speed sensor (Part No. 2560) for measuring airspeed
• Direct connection to a GPS logger possible for data logging to a file
• Recording of all data on the Multiplex sensor bus when operating with M-Link
• Recording of receiver battery voltage
• Power supply automatically provided by the receiver and/or drive battery
• Manual recording start via built-in button
• Recording start can be set based on various conditions
• Current status is indicated by three LEDs
• View measurement values live or recorded directly using our UniDisplay
• Parameter settings possible via PC, UniDisplay, and telemetry
• Supported by LogView software www.logview.info
• LogView is a very comprehensive yet easy-to-use analysis program for the PC that supports a wide variety of different measuring and charging devices from the model-making sector.
• Simple and clear evaluation of measurement results using charts on the PC
• Free firmware updates available via memory card (the firmware file can be found here)
• Can be used virtually anywhere thanks to its compact size and light weight
