GPIO Connector: External Input
A single 15-p in general p u rp ose inp u t / ou tp u t (GPIO) connector is u sed to receive or control external
signals. For exam p le, the GPIO connector can be u sed to receive EXSYN C, PRIN (p ixel reset), and
d irection signals.
The GPIO connector is p rogram m ed throu gh the GUI ap p lication. In Cam Exp ert the relevant p aram eters
are located in the category Inp u ts Grou p .

A schem atic of the TTL inp u t circu itry is show n in
Figu re 13: TTL Inp u t Schem atic. The inp u t signals are fed into the engine from external sou rces via the
GPIO connector.
GPIO Isolation
All of the GPIOs are isolated from the rest of the cam era and th e cam era case. They are not isolated w ith
resp ect to each other and share a com m on retu rn (grou nd ) throu gh p in 5 of the GPIO connector.
N ote: The shell connection of the GPIO connector is not isolated and it shou ld not be u sed as a retu rn
(grou nd ) for the GPIO signals. The shell connection is attached to the cam era case.
GPIO Configuration
Refer to Ap p end ix C: GPIO Control for a d etailed d escrip tion of the GPIO u se -cases and configu ration
op tions.
