Transcript of SVCam I/O modules – the camera as an IO controller
SVCam I/O
In-Camera Controller and DriverIncluded in every SVCam
SVCam I/O
Versatile inputs» Trigger
signal handling
» Generatingmultiple signals
Open drain outputs
SVCam I/O – Customer Benefits
All programmable Displacing an external LED controller Reducing complexity Cutting costs
» Fewer cables» Fewer components» Smaller application

Input
4 inputs» Triggers
› Voltage up to 24 V Signals
» RS-232By the way:Opto isolatorFor new EXO & SHR series
IOMUX

IOMUX
Switch Matrix Input to
» Debouncer to› Pulseloop0 to
Output2 open drain› Pulseloop1 to
•UART toOutput3 RS-232
by the way: Inverter and set-to-one
Before and after every IOMUX module
Invert signal» Trigger interpretation can
also be inverted Set signal to „1“
» Just turn the signal ON» or turn it OFF by inverting it at the same time
Debouncer
Eliminates „ringing“» Glitches: spikes, overshoots
1. Masking the input for a period of time
2. Comparing the signal after the period
Prescaler
Masking every 2nd, 3rd, 4th, and so on
by the way: high low trigger
Schmitt Trigger
Programmable values that have to be crossed for a trigger interpretation true
Sequencer
One trigger signal results in:» Up to 16 intervals with individual:
› Total length› Exposure time› PWM frequency› Up to four strobe outputs with individual
• Intensity• duration
Sequencer
One trigger signal:
by the way: PWM
Pulse Width ModulationIntegrated in the Sequencer
regulate the intensity of an LED light» Extend LED life cycle
Set base frequency period length» for each sequencer interval
Set duty cycle Δ in %» for each sequencer output
by the way: PWM
25 % intensity
50 % intensity
75 % intensity
Pulseloop
Four individual pulse generators» Set delay and duration time
Pulseloop
Four individual pulse generators» Set number of loops
An individual PWM
Pulseloop
Camera cascade
» Exposure internal cam1» Exposure external cam2» Trigger cam3
Pulseloop
Wait for second shoot
After first aquisition software demands a second exposure
Pulseloop
or simple:Exposure and Light …
Output
Up to four open drain outputs» 0.7 A permanent» up to 3 A over 40 ms
Signals» RS-232
MOSFET transistors
Output
SVCam I/O – Customer Benefits
Eliminates the need for an external controller Simplifies cabling Reduces costs Rises value of ownership of an SVCam
