The Composite SYNC OUT pin is TTL compatible and re-outputs the Composite SYNC IN
(also when SYNC on component [green, red or blue] is selected) and can be used for camera
synchronisation.

General Purpose Input /Output connector
The General Purpose Inputs and Outputs are connected to the
picasso
TM
by a SUB-D9 female
connector. In Figure 4 you see a drawing of the SUB-D9 connector. The pin connections are
listed in Table 2.
When you use the general-purpose inputs or outputs you have to connect an external 5V power
supply. The maximum voltage is 5.5V and the input current is 10mA.
When U19 and F1 is placed [see Figure 1] no external power supply is needed. U19 will provide
the external 5V.
F1 is a fuse with the following specifications: 250mA, fast. Ask ARVOO support for more
information.
ATTENTION: The maximum output current is 100mA.
The outputs are open drain, which means that logic 1 will force the output to ground. A wiring
example to connect an output is given below.
ATTENTION: When the computer is turned off and the external power supply stays up the
output will also be forced to ground.
