2.2  Electrical Installation: Connections and I/O Signals

All 

Schäfter+Kirchhoff

 USB 3.0 line scan cameras can be operated with a USB 2.0 interface. Note that there might be 

limitations in terms of the maximum data transfer rate. The details for your camera can be found in section 

1.4 Line 

Scan Camera - Specifications (p. 5)

.

If the power consumption of the camera exceeds 4.5 Watt (USB 3.0) or 2.5 Watt (USB 2.0), then connect an external 
source to socket

(see also 

 Accessories (p. 34))

:

•  The USB 3.0 interface provides data transfer, camera control and power supply capabilities to the SK22368U3TOC 

line scan camera. If you want to operate the camera in Free Run (SK Mode 0) trigger mode the USB 3.0 cable 
is the only connection you have to make.

•  For any kind of synchronized operation, the external trigger signal(s) must be wired to socket 

2

. A frame-

synchronization signal and two separate line-synchronization signals can be handled. The various trigger 
modes are described fully in section 

 Synchronization of the Image Acquisition with the Feed Rate of the 

Object (p. 18)
