You can begin the wiring of the inferior card.

Start with the 4.7K R1, R2, R3 and R4 resistances. Don't take the wrong side ! The components (except the pre-wired CMS circuits and some connectors, see futher) are connected up on the side of the ground plane. These four resistances are used as pull-up to +5V for some control signals of the PC (these outputs are linked to the +5V through 4.7K resistances to ensure a better commutation). These 4 signals aren't used for the standard running of Audine. They concern the accessories associated to the camera, like the control of a filters wheel or of a second camera. The wiring of the R1,R2,R3 and R4 resistances is hence optionnal.

Left, the R1 resistance is ready to be soldered. Right, R1 to R4 resistances soldered. First, you can not solder these resistances, they are not useful for the standard running of the camera.

Then, solder the protection diodes D1 and D2 (1N4002). Be careful, unlike the resistances, it's imperative to respect the direction of the assembly.The line drawn on the diode must be oriented the same way it is on the assembly plan. The legs of these two components have a large section. You must force a little to introduce them in the holes of the printed circuit. A good advice, think twice before adding a polarized component. Never rush around.

The D1 diode is placed.
Take care of the orientation of the D1 and D2 diodes. The ring engraved on the body gives the direction.
Place the 100nF capacitors C5, C6, C7 and C8. These components aren't polarized. For their assembly, there is no particular precaution to take.

Left, the tentalum drop capacitors. These capcitors are polarized. Care must be taken to their orientation. The vertical line (possibly doubled with a + sign) identifies the positive pin. On this image, the positive pin is located on the right of the component. On the implantation plan, the positive pin is located on the side of the line drawn on the symbol of the component. Right, non-polarized capacitors. It will be an ordinary orientation at the moment of the wiring (it's the case of the 100nF and 1nF capacitors).

Take four 100nF capacitors...
C5, C6, C7, C8 capacitors are wired.

Solder the 10mF capacitors C1 and C2, then the 4.7mF capacitors C3, C4, C9, C10, C11, C12. All these capacitors are of the type tentalum drop, they are polarized. You must take care of the direction of the assembly. These components have a silk screen printed + sign, often doubled with a line. These indications designate the + leg of the component. On the wiring plan, this leg is designated by a +. If you reverse the direction, the capacitor is very likely to spread a nice black smoke and get a brown shade when you power it on. It's better to check twice than once the orientation of each component you solder.
