3 . Standby Instruments Controller Connections The S.I.C. can drive a set of Standby Instruments and is designed to be used in Airliner Cockpit simulation. +5 Gn d Gn d + CN CN8 CN9 CN5 CN6 CN7 CALIBRATED TO 0.000FT VACUUM (Note: the connections in the above picture between the different instruments and the S.I.C. board are just for illustration only. Please see Chapter for exact connections) This document describes how the instruments are connected and how they are driven by the S.I.C. and what the signals and their description mean. Although that the document is very clear and can be read by non-technical persons, for full understanding we do recommend that the reader has a basic knowledge of electronics When you like to expand your airliner cockpit with more instruments and gauges, for example for the overhead panel, we do recommend the use of the Multi Controller, an expansion board offering I/O lines, which are each programmable to read out a switch, to drive a LED or to drive a single pointer gauge per each I/O line. Up to of these board can be configured in addition to the S.I.C.. All controllers (including the S.I.C.) are connected to the PC via USB. Instruments controlled by the S.I.C. - Attitude Indicator - Altimeter - Heading Indicator (with or without Autopilot Heading Bug) - Airliner Airspeed Indicator 50 Knots - Wet Compass Software The driver software to connect the S.I.C. to Microsoft Flight Simulator is the same software as used for the CCU controller board. The S.I.C. is actually a smaller version of the CCU. You can download the driver software from the support section of the SimKits website. Please download version.xx and use the software installation manual for the TRCLink software.xx/ Simkits & The Real Cockpit are trademarks from TRC Development Page

To regulate the light, connect a potentiometer of 0Kohm to CN, where the wiper needs to be connected to the middle pin. Regulating Light CN Lights always on CN When the light needs to be on all the time, just connect the middle and left pin (as in the drawing) together.

5 . Connectors and their I/O lines The description below informs you on what the I/O lines of each connector mean. Warning: connecting hardware to this I/O lines which draw excessive current, input high currents or short circuit outputs may damage the delicate electronics on the board. Damages caused by improper connection of hardware are not covered by the limited warranty. For each connector the signal names are mentioned. These signal names can be found back on the schematics (last page). When necessary a description of the signal is given. - The term Digital Input means and input towards the S.I.C.. - The term Digital Output means a signal which is coming from the S.I.C. towards the device. - The term Analog input means that this input can read an analog value between 0 and 5 volts with a resolution of approx. 0 different values. - The term Analog output means that this ouput can produce a voltage between 0 and 5 volts which can be set by a digital value of 8 bits by software. - The Term Ground or Gnd is the common ground of all electronics signals. - The term +5v. or Vcc is the 5 volts power needed to drive the electronics on the S.I.C. board and some electronics inside the gauges. - The term +5v.X is the 5 volts power needed to drive the servo motors and is derived from the separately connected Power Supply. The S.I.C. needs different positive voltages of 5 volts. One 5v. is supplied through the USB connection from the controlling PC and is used to power the electronics except the servo motors. The other 5v. (marked as 5v.X in the schematics and literature) is powered by an external (PC AT) power supply via CN. This is designed in this way because the servo motors draw more power than can be delivered through the USB connector from the controlling PC. Both 5v. supplies must be connected in order for the electronics and gauges to function properly. Modified Servos In some instruments, lilr the Wet-Compass, the Heading Indicator and the Altimeter, so-called modified servos are used. An normal servo is and electro motor driven by electronics inside the servo motor. Via a number of gears, a small electric motor drives the output axis. The output axis is also connected to a normal potentiometer. The output axis is limited in hardware to turn maximum of approx. 80 degrees. The potentiometer is used to feed back the position of the output axis to the electronics of the servo. The output axis of the servo can be controlled by a pulse width applied to the servo to turn it into a certain position. This feature is used in most gauges. However, some gauges need a continously rotating movement. For this we have choosen to use a standard servo motor and modify it in such a way, that the output axis can turn clockwise and anti clockwise without limitations. Due to such modification, the position of the output axis cannot be determined anymore by the built-in potentiometer. Therefore the mechanics inside the gauge now are also connected to 60 degrees turnable potentiometers, called PIHER position sensors. These position sensors however, only measure a part of the 60 degrees. Their electronic sensitivity is approx. 0 degrees. By using of such sensors and placing them in line but 80 degrees shifted, the S.I.C. electronics and software now can pickup the position of the output axis over the full 60 degrees. Finally, by software a precise position of approx. 0.5 degrees is being calculated. Rotary Encoders A rotary encoder is a mechanical dual switch which can rotate continously. During this rotation the switches are closed and opened over times for a full revolution, but not exactly at the same time. The direction of the turn can be determined by the phase of which of the switches are closed first and which last. Simkits & The Real Cockpit are trademarks from TRC Development Page 5

6 The software of the S.I.C. reads out both switches and translates this into a signal telling the flight simulator software that the certain knob is turned left or right and at what speed. Potentiometers In principle, all analog inputs do measure the position/value of a potentiometer (turn or slide). Throughout the whole design of all instruments, a 0Kohm potentiometer is used which is on one side connected to +5v. (Vcc) and on the other side to Ground. The wiper of the potentiometer is connected to the analog input on the S.I.C.. Potentiometers are used in a.o.: Yoke, Throttle, Mixture, Propeller, Flap Switch, Trim and the Piher Sensors (in essence a potentiometer) in the gauges Altimeter, Heading Indicator, ADF and Compass.
