Interfacing Karmin3
6.1
Connecting to SceneScan
Karmin3 is intended for use with the SceneScan or SceneScan Pro image pro-
cessing systems. Karmin3 should be connected with a Micro USB 3.0 cable
to one of SceneScan’s USB ports. It is highly recommended to secure the
Micro-USB-connector with lock screws. This requires a locking USB3 cable.
In addition to the USB connection, Karmin3 also requires a connection to
SceneScan’s trigger port. A suitable trigger cable can be obtained from Nerian.
It is alternatively possible to use a trigger source other than SceneScan. In this
case please make sure that SceneScan is configured appropriately and that the
trigger source obeys to the voltage levels listed in Section 3. Figure 3 shows
Karmin3 connected to SceneScan Pro with a USB and trigger cable.
The trigger signal must provide an appropriate trigger frequency that can
be matched by the cameras and the selected SceneScan model. The possible
frequencies for different system configurations are listed in Table 3. In low-light
situations the desired frame rate might not be achieved if the sensor exposure
time is too high. In these cases, an appropriate exposure time upper limit
should be configured in the SceneScan settings.
