I am a beginner. My plan is making a GA cockpit such as C172 and my first goal will be making a full radio stack such as RS372 type. I have inspected I/O cards and FsBus system to understand for choosing which one will be easier for me. FsBus is closer to what on my mind is. But there are some items that I could not understand. Before starting I will need some help from experienced guys. I am sorry if my questions are so stupid things...Answers will ensure me to understand better the FsBUS system.- Radio(1-2)/ON/OFF/TEST switch is not functional by mouse click on the radio stack for some aircrafts (C172), but it is functional for some aircrafts (socata TB-20 GTII-not a original aircraft), why? Is there any body who knows offsets of this button in FSUIPC list.-There are some prediefined switches and displays which come with FsBus Router. In addition there is a file named FSIF.ini in which FSUIPC offsets are defined. If I need to add new switch such as Radio(1-2)/ON/OFF/TEST switch that is not among neither predefined switches in FSBUS Router nor the offsets defined in FSIF.ini file, what sould I do? Is there any way of adding new offsets to FSBUS, how?-If I need to add a three position switch such as fuel tank selector (Left, OFF and Right), what should I do again?-Will I need FSBUS CDK during my simple project?-and the last one for present, how will determine the unknown switch offset by FSInterrogate. (Please descibe as if I am a child :))Thanks in advance...

In fact both IO cards and FSBUS rely on offsets. So what you can do with both systems will be more or less the same.I build fsbusNG and are satisfied with it. The latest fsbus release contains a kind compiler language with which you can build in logic. In that way you can simulate things that are not even in fs itself.Radio on/off/test; use the progie fsinterroater, it is in the fsuipc for programmers package. Run it, push the button in your socata, and see what offset changed in fsinterrogator.If nothing changed, perhaps it is a function of that addon/gauge tself , then it has no offset. In fsif.ini are the most used parameters. But if you would like a instructorpanel and make a switch for visibility or ceiling or whatever, thats possible. Everything that has an addon can be entered in the ini file. If your project is simple , you can stay with the present fsrouter sw. The CDK is for the more advanced functions. Compare it with the SIOC language of IOcardsregardsnorberthttp://home.wanadoo.nl/norbert.bosch/

Thank you Nobert,Your explanation made me little bit clear.best regards

Hi Norbert,I need some more assistance;Could you define some FsBus Router settings shortly?Switch-------------Inverted: ?Down event: ?Up event: ?Auto repeat: ?Toggle: ?Down value: ?Up value: ?Display------------Leading Zeros: ?Offset value: ?Display Offset: ?Display Size: ?Led-------------Min: ?Max: ?

Just experiment. I got to know the function by experimenting too.Inverted: it turns the function of a switch the other way around, so on = off and vice versa, when you soldered the wrong way, use this oneDown event: what you want t o happen when the switch is down Up event: what you want t o happen when the switch is upAuto repeat: it keeps doing the same over and over againToggle: functions as a toggle switchDown value: value a offsets get when switch is downUp value: sameLeading Zeros: when you use only a 4 digit display (xponder) set this to 2Offset value: ?Display Offset: ?Display Size: ?Do not know the others by head at the moment. I am not at my fsbus pc at the moment. Will have a look at it later.

Display size means how many digit displays you are using. For example, when you use displays to show attitude you should set thi to 5.
