Now, you must connect the two female
connector bars that will link the two boards. These two MODUCOM simple
row connectors, CON3 and CON4, must be mounted on the opposite side of
the board, unlike the other components. You were in the same situation
when you set the connectors DB15 and DB25 of the inferior board, and you
must pay an equal attention while operating. Solder the bars well plated
to facilitate the setting of the boards. The connector CON3 must be cut
in a bar to obtain 14 contacts. As for CON4 which has 15 contacts.
The bars CON3 and CON4 must be mounted on the opposite side of the
Solder the tulip socket of the integrated circuit U4 to U8. Note that
if you want to install a KAF-1600 in Audine, you mustnít set the U7 and
U8 sockets because they obstruct the setting of this CCD. In such a case,
you would have to solder the two corresponding integrated circuits directly
onto the board. As the KAF-1600 price is about five times great than the
KAF-400 one, youíll certainly have to solder all
the sockets. Furthermore it will ease any checking, if needed.
All the circuit sockets are mounted. Thereís a lot of soldering
but not any difficulties for this time.
The extension port TB3 must be manufactured from a AMPMODU
bar. The board drilling allows a two-row bar to be plugged in. But if you
only use one row, wires can be soldered instead of the second one to bring
the port elsewhere.
This extension port is made to fit the camera with accessories that
require a power supply or specific signals to run. Its pinout follows (letís
cast a glance at the superior
board layout) :
Pin 1 = C2:15 (designed to power internal accessories from C2 : choose
the value you need),
Pin 2 = C2:14 (ground for the previous power supply),
Pin 3 = C1:14 (duplexes C2:11, through one of the 74HCT14 trigger),
Pin 4 = Ground for the electronics,
Pin 5 = +5VD
Pin 6 = +15VA
The smart extension port allows you to upgrade your Audine camera.
A mistake has been noticed on the printed circuit board : the CCD pin
14 (Vsub) isnít tied to the ground, whereas it should ! This route has
been forgotten while designing the printed circuit board. A short wire,
called strap, should suit the situation. Wrapping wire ideally fits
here. The CCD pin 14 will join a close ground pin, on the soldering side,
as shown with the following illustration :
The red line shows how to fix the printed circuit board bug.
This picture shows the strap joining the CCD pin 14 to the ground.
Now the electronic boards of the Audine camera are wired out. Before
acquiring your first CCD picture youíll have to make the cable
for the PC link, perform electrical tests and few adjustments.
But letís come again to the camera power
