Digipeater CLB26 User Manual Introduction The Digipeater CLB26 is designed to overcome problems with image processing systems ® in which distance is a limitation. A standard CameraLink cable can be used to connect a camera to a frame grabber over distances of up to 10 m. It frequently occurs, however, that twice this length is required to feed signal cables through the trunking of automation systems.
Digipeater CLB26 User Manual Connections / Block diagram Fig. 2 shows a block diagram of the Digipeater. Data from the camera are connected to Port 1. The regenerated data are transmitted on to the frame grabber from Port 2. The direction of the data flow is marked with arrows on the Digipeater case (see Fig.

Digipeater CLB26 User Manual When installing cables in the vision system the cables have to be handled with extreme care to avoid destruction of the inner cable structure. Please do not apply extra force to the cables and mind the minimum bending radius. Otherwise the characteristic impedance of the cable will not be longer 100 Ohm and transmission errors or an interruption of the data transmission will occur.
Digipeater CLB26 User Manual Performance of the complete system The performance of the vision system is determined by the performance of the vision components at given bandwidth of the data transmission. The bandwidth of the ® CameraLink interface is given by the bit depth of the camera, the number of taps and the transmission frequency (PixelClock frequency).

Digipeater CLB26 User Manual ® In vision systems most often AWG28 CameraLink cables are in use. Table 1 shows the distances for different configurations and transmission frequencies for an AWG28 ® CameraLink standard cable. High performance cables, high flexible cables, cables for drag chains and robots are available from Photonfocus.

Digipeater 1/2 Fig. 11: Data transmission in a long mounting line The Digipeater CLB26 can also be used for signal regeneration at cable feedthroughs or connections between cable sorts. This is often the case in robot applications where high flexible cables are in use on the robot itself and rigid cable are used to bridge the distance between the place of the robot and the system control unit.
