2.1 General Information
GL1020FTE The data logger GL1020FTE is flight test equipment dedicated to record avionic CAN
bus communication. It is designed for:
> Application in the pressurized fuselage area
> Fulfilling the typical requirements of aircraft EMI
The GL1020FTE is a data logger with USB interface which records messages and
analog values on the inserted SD card. This SD card is located in the housing and is
not accessible from the outside. The logger can be configured with the Vector Logger
Configurator. The installation is described in chapter 3.2.2 Installation Vector Logger
Figure 1 – GL1020FTE
Avionic features The GL1020FTEis designed to support the following avionic features:
> Designed for compliance with DO-160E.
> Hardware prevention against influencing the aircraft:
> No sending on the CAN bus
> No acknowledging capabilities
> Short circuit protection
> Protection from indirect lightning effects.
> Protection against dust and humidity.
> Pressure exchange through a semi permeable membrane to prevent humidity
accumulation in the housing.
> Suitable for rough surroundings and resistance against:

of CANgraph) or third party tools.
Logging features The logger provides various logging features like:
> SD card is not replaceable without opening the housing.
(This improves stability against vibration, shock and acceleration, as well as EMI
compliance)
> Mounting plate with bonding point.
> RF emission and susceptibility according to typical avionic requirements.
> Operational at altitudes up to 36,000 ft.
> Conditional logging:
Automatic start of logging on power-up or on user defined conditions. Stop
logging on power down or user defined stop conditions. Filter options may be
used to reduce the amount of data recorded.
> Triggered logging:
Trigger on symbolic messages, CAN identifiers or signal values with configurable
pre- and post-trigger times for test campaigns dedicated to detect certain
situations on the bus.
> Very short start-up time:
The logger is designed to keep boot time especially short, in order to record
communication or to be ready for a trigger as soon after startup as possible.
> Configurable LEDs for indication of various conditions.
> Beside CAN traffic, measured values from analog inputs can be stored time-
synchronously.
> Flexible configuration with easy-to-use configuration tool.
> Fast download of the configuration to the logger.
> Fast data upload via USB 2.0 and conversion in multiple data formats (e.g. BLF,
ASC, MS Excel) for offline analysis in CANoe, CANalyzer, vSignalyzer (successor

Configuration
1. Start the program Vector Logger Configurator.
2. Open a new configuration via the menu File|New Project…. Select in the
displayed dialog the logger type GL1020FTE.
3. Select suitable baud rates for each CAN channel (Hardware|CAN Channels).
4. Select the timeout to sleep mode (Hardware|Settings).
5. Configure the logger for a permanent logging of all data from switching on to
switching off of the logger by activating the Permanent long-term logging option
in Logging|Triggers.
6. Connect the logger to the PC via USB cable. If the logger is not automatically
detected, press <F5> to refresh the display of connected logger devices.
7. Download the configuration via menu Configuration|Write to Device….
8. Set the real-time clock via menu Device|Set Real-Time Clock… (recommended
before first logging). Afterwards the logger is automatically switched off.
