Page 13: Electrical Installation
AS27500. AWG22 (0.34 mm²) is a sufficient cross section for power supply of the SCU. Preassembled wiring harnesses are available as accessories for simplifying the installation. For part numbers see Chapter 5.7 or contact RS Flight Systems directly. Ensure that proper grounding connections are made and that the various ground potentials are not connected outside of the Main Unit. -
Page 14: Lane A / Lane B / Lane C Connector
Figure 5-1: SCU Sub-D connector pin numbering Lane A / Lane B / Lane C Connector The Lane A Connector carries the power supply pins of the SCU (Pins 1 and 5) and Display CAN Lane A (Pins 2 and 7). Table 5-3 specifies its pinout. Reverse polarity and voltage surge protection are implemented on the Lane A connector, therefore power must be supplied there. -

Page 17: External Connector
An extinguishing diode across the relay coil is not needed and a suitable relay is available as an accessory (see Chapter 5.7). The Starter relay is intended for use on unmanned aircraft. Feel free to contact RS Flight Systems for different sensor and actuator configurations. External Connector The I/O connector offers filtered, but unregulated power output and further general I/O connections. -

Power Output (9-32 V) Table 5-7: External Connector pinout Feel free to contact RS Flight Systems for your needs regarding I/O applications. Examples are automatically controlled LANE and fuel pump switches, temperature-controlled fan activation (Intercooler, Oil cooler), UAV applications and many more. - Page 19 The pinout of the LED connector is listed in Table 5-10. For the connection of the warning lamps A and B please refer to the BRP Rotax Installation Manual 912iS / 915iS. The pre-resistors and the parallel resistors are integrated in the Front Panel and the Display Panel. Therefore, the pins 1-4 can be directly connected to the BRP Rotax HIC A and HIC B connectors.

Page 22: Operation
Operation Startup Power Relay Function For the Rotax 912iS / 915iS engine, the spring-loaded “Start Power Switch” (SPS), as specified in the BRP-Powertrain installation manual, has to be activated prior to engine start. As soon as START has been commanded and the engine is running, the SPS has to be released. The function of the SPS is to temporarily feed aircraft battery power to the Engine Control Unit (ECU), so that engine start is possible. - Page 23 with 0001 being the decimal number, which is incremented by one for each new file and allows for 9999 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 4-character ASCII string in the file "TOPDAT.CFG", which is also written to the card.
