4. Mechanical Installation
Upon delivery, undertake visual inspection of the package contents for signs of transport damage and
verify the information on the type plate sticker against your order. Do not open the device housing.
For longer storage of the device, select a dry and clean environment. Make sure that the device is not
stored near strong heat sources and that no metal chippings or other dirt can get into the device or its
connectors.
As waste heat is dissipated via free convection, leave at least a 5 mm gap from the aluminum surfaces
to any other object. Forced cooling is not necessary.
The installation must be in accordance with the appropriate guidelines approved by the respective
aviation authority. The person installing the device is responsible for compliance with all applicable
legislation.

5. Electrical Installation
The iSCL has three connectors on the rear side, shown in Figure 4-1. Label, type of connector and usage
are listed in Table 5-1. Before powering up the unit for the first time, carefully check your wiring. The
wiring diagram is shown in Figure 5-1.
There is one microSD slot to update the firmware and store data. One DIN-style connector for the
external GPS receiver to import GPS data. And a D-SUB connector which functions as the main
connector to power up iSCL and transmit data. The pinout is seen in Table 5-2.
Place the GNSS antenna in a spot where it has maximum optical visibility of the sky, e.g., the glare
shield on top of the instrument panel. Poor GPS reception has no adverse impact on the operation of
the unit yet may impair recordings of position, ground speed and UTC data.

5.1 LANE A Connector
The iSCL uses a standard D-SUB 9 connector. Pin 1 is supplied with +9 - 36 VDC, Pin 5 is ground. The
power wire must be fused either with a 1.0 A circuit breaker. The P/N of a suitable circuit breaker is
listed in Table 5-3. See Figure 5-1 for an exemplary wiring. Interconnect CAN termination Pin 3 and Pin
8 only, if not other CAN device is connected to CAN Lane A. Pin 4 and 8 can be used to connect further
devices to the CAN bus. Pin2 and Pin4 are internally connected in the iSCL. Pin 7 and Pin 8 are internally
connected in the iSCL.
The extended pin allocation is shown in Table 5-2.

6. Operation
In this chapter operational procedures for the iSCL are described.
6.1 Startup
The iSCL starts up as soon as soon as sufficient supply voltage is provided.
6.2 Flight Data Recording
The iSCL records all data transmitted by the ECU over Lane A and the respective CANaerospace
interface. This function is only active as long as an SD card is inserted. For each restart of the iSCL or
every 6 minutes (0.1 recording hours) of runtime, a new file is created and the previous one is closed.
The file naming convention is:
DAT00001.CAN
with 00001 being the decimal number, which is incremented by one for each new file and allows for
99999 different files to be created, named and stored. The number of the last file which has been
closed and written to the SD card is stored as a 5-character ASCII string in the file "TOPDAT.CFG", which
is also written to the card. Most of the data is transmitted 10 times per second and a typical data rate
is 12 kilobytes per second. Using a 128 GB SDHC memory card, this results in a maximum recording
time of 3,000 hours.
A powerful Engine Management Debriefing Station (EMDS) software for the Microsoft Windows, SuSE
Linux and Apple MacOS X operating systems is delivered with the iSCL. This tool (see Figure 6-1 to
Figure 6-5) allows for visualization and post-processing of the recorded data as well as a three-
dimensionally georeferenced data conversion to Google Earth compatible files.
The EMDS software is available on the following server:

6.3 Software Update
The iSCL allows for easy conduction of software updates through the SD memory card interface. The
software is delivered in compressed .zip-files with the following exemplary structure:
iSCL_SW_iSCL0.1.zip -> iSCL_SW_iSCL0.1-> mb0.srd, mb1.srd
The binary software upgrade files (.bin) have to be copied on a microSD. The microSD card has to be
placed inside the microSD card slot. The binary file is recognized by the iSCL when power is applied,
and the device boots up. When an update file is detected, the content is automatically programmed
into flash memory and the device starts up using the new software. Upon successful firmware update,
the binary file is deleted from the microSD. If you need to do another firmware update, you have to
follow the same procedure as above.
Please ensure every step before flashing.
•Use a microSD card with max. 128 GB
•Make sure to format the microSD card in FAT32 format (exFAT/NTFS is not supported!)
•Ensure the microSD card is empty
•Download the latest firmware from the RS Flight Systems website ( https://www.rs-
flightsystems.com/product-page/is-canaerospace-logger )
•Do not rename the firmware file
