Case 1: Control Input = Enable
Control input = Enable means that IN2 must be connected to V+ (+24 V DC) to allow the external trigger.
Case 2: Control input = Activate 0 or 1
This function allows the Control Input to determine whether detector 1 or detector 2 is evaluated. A change in the state of the
control input (B) can take place in period “5” (Ready = high). A high level (V+) on the control input IN2 means evaluation according
to detector 2 configuration, a low level (V-/GND) means evaluation according to detector 1 configuration (more details below).
Case 3: Control input = Activate 0 to 31
This function allows the Control Input to determine which detector is evaluated by using a series of pulses during the Ready state. In
period “5” (Ready = high/V+) pulses are counted “C” (type: 5 ms pause/5 ms pulse/5 ms pause/etc.). The next evaluation takes
place with the detector corresponding to the number of pulses counted. The count always starts at 1, regardless of which detector
was active previously. The pulses must be generated bounce-free, preferably by a control system (more details below).
Case 4: Control input = Teach temporary or Teach permanently (only possible on detector 1)
This function allows the MultiSight to be taught a new pattern without being connected to the software. In period “5” (Ready =
high/V+), a high level (V+) can be applied at IN2 to trigger a temporary (saved in RAM only) or permanent Teach (saved in flash).
This must be applied at least until the next rising edge at trigger input IN1. Then the new pattern is taught in detector 1 and saved
according to specification. The control input IN2 must be pulled low (V-/GND) before the next rising edge at trigger input IN1, or
another Teach is triggered. In this mode, only detector 1 is used and overwritten by the next Teach. Detector 1 can still be logically
linked to other detectors (more details below).
Additional Details on the Special Uses of the Control Input
Control Input: Activate 0 or 1 and Activate 0 to 31 (Cases 2 and 3)
The parameter Control Input can be set up to allow the control input IN2 to select between the different detectors. The parameter
setting is Activate 0 or 1 OR Activate 0 to 31.
If control input = enable (default state), IN2 (grey wire) MUST be
connected to V+ (24V DC) for the external trigger to work.
When one of these options is selected, the following parameters
must be set accordingly for all used detectors:
Control Input must be the same for all (either “Activate 0 or 1 OR
Activate 0 to 31”) (more details below)
Shutter Adjustment = Manual
Trigger mode = Triggered
It is recommended to keep a list of which pattern is saved in
which detector number.
