(PC bracket viewed from outside)

VIDEO2 and VIDEO3 are selectable color or monochrome composite inputs. Each of them is terminated with a removable 75Ω resistor. The POWER pin can be connected to +5 V or +12 V.

I/O Lines

Picolo offers four I/O lines named IO1, IO2, IO3 and IO4. They are available on the DB9 connector. They can be read or written by software. They have a common ground and are TTL compliant. Moreover, IO1 can be configured by software as an external acquisition trigger line for acquisitions.
