Interface is opencockpits.com IOCards system with SOIC as base One USB Expansion card in left, right and instrumentpanel and the amount of Mastercards needed per panel. Added to these mastercards are applicable 7 Segment display cards, LCD, Servo and stepper cards. To interface the SIM, DCS-A-10C in this case, I use Oakes scriptfiles (Thanks Oakes ! ;-) where also many contributed along the years. Further down, you find an attempt to consolidate, for each quad, the related parts in the scriptfiles. Note that I’m nothing like an expert in this area so there will be errs and bade coding etc. The contens of these files may also be changed without notice so use these for example if needed. Still a long way to go though.... |

As seen in the QuadRef page, Most of the quads are built is individual blocks and connected to a In/out put break up card (1-3 per quad) connected with a 40 pin ribboncable using the standard 2*20 pins contact. Where applicable, several Quads are connected in parallel to a Mastercards In or Output channel to utilize each channels ports. The ‘breakup’ cards in this case are PCB only, (requires a separate order and probably large quantity as in my case) since I solder each connection and use angled 40 pins connectors. |

Connecting the switches , rotaries etc is a straight on task but the 7 segment displays as in UHF and VHF radio modules were a mindnibbling experience. I tried first to solder’em on a perf board but gave it up due to wiring havoc. Amount of cabling needed in the (small) available space were simply not possible to fit. I fired up EagleCad and made the drawing below. Exctracted the CAM and drill files and sent these to a PCB manufacturer and the result was at least usable :) (i.e not very professional) In below sketch you find the UHF, VHF and “Tape” indicator PCBs. Holes are 3,5 mm, Holes round the edge of the board is to ease were to cut the pieces. Single side PCB in this case and you might need to add a patchcable here and there. Note also that the signals a-g and common cathod numbering is not always in sequence. Decimal point is to be used together with a pot to enable trim to correct intensity The double a-g connectors on the VHF (lower left) of the board is used to loop the bus up to the channel frequency indicators (top right). Indicator selects is looped seperatly 7 Seg disp I used is www.elfa.se 75-506-92 |
