Electrical Styles

You are provided with five electrical styles for the strobe line, according to parameter StrobeCtl. The default electrical style selected by MultiCam is OPTO.

StrobeCtl

Electrical style

OPTO

The strobe line is issued on an optically-isolated pair pin. The + pin is the collector and the - pin is the emitter of an uncommitted photo- transistor driven by LED-emitted light.

TTL

The strobe line is a TTL compliant signal.

ITTL

The strobe line is an isolated TTL compliant signal actively tied to the high or low state.

IOC

The strobe line is an isolated TTL compliant signal actively tied to the low state and passively tied to the high state through a 3,000Ω pull-up resistor.

IOE

The strobe line is an isolated TTL compliant signal actively tied to the high state and passively tied to the low state through a 2,000Ω pull-down resistor.
