Camera Interface Overview
6.1
Inputs, Outputs and Enhanced Features
The Digital I/O Module allows the connection of 7 external Lines :
3 dedicated inputs (Line 0, 1 and 2) that can generate 2 Line Triggers (LT1 and LT2) and one Frame
Trigger (FT) that will be used as inputs in the Enhanced features Block.
4 convertible generic Inputs / Outputs (Line 3, 4, 5 and 6) that can generate up to 4 additional Input
Lines (L3, 4, 5 and 6) that will be used also in the Enhanced features Block or Used as Outputs.
A flexible in/Out block in RS422 or TTL with different detection levels (3.3v, 5v, 12v, 24v)
A Debounce and Inverter block that can filter and invert the internal Signals Inputs once affected to
LT1, LT2, FT, L3, L4, L5 or L6.
The Enhanced Feature block completes the treatment on internal signals to generate Triggers :
A delay dedicated to the Frame Trigger only (FT)
A Full Rotary Encoder management (Quadratic with or without reverse miscount) that use by default
LT1 and LT2 as A/B Inputs. It can be bypassed to output by default LT1 as single Line Trigger input.
A Rescaler following the Rotary Encoder module (available also if Rotary Encoder is bypassed)
2x Counters and 2x Timers
The Internal Signals provided by the Digital I/O Block and the Enhance Feature block are :
LT1/2 : Line Trigger 1/2
RO : Rotary Encoder Output
FT : Frame Trigger (Signal Issued from the DigitalIOControl Block)
Frame Valid (Signal issued from the Frame Valid GenICam Trigger)
Frame Start (Signal issued from the Frame Start GenICam Trigger)
FLO (Exposure Active in the Sensor)
Lx : Line Inputs (L3, L4, L5, L6)
TE1/2 : Timers End 1/2
CE1/2 : Counters End 1/2
Then these Signals will be used to generate the 4 possible GenICam Triggers :
Line Start : With Exposure mode Off or Timed and a possible Delay before Exposure.
Exposure Active : With Exposure mode in TriggerWidth, linked to the Trigger signal level
Frame Start : The Frame Length is fixed and set by “Height” parameter.
Frame Active : For a variable Frame Length which depends on the Frame Trigger
