Connectors

PSC-CAN

Connect the PSC-CAN to the previous node (or controller) using the 9-pin female connecter. Loop to the next node by using the 9-pin male connector. If the PSC-CAN is the last node, the 9-pin male connector shall not be connected and a 120Ω termination resistance shall be included in the 9-pin female connection. Note that in a correctly set-up CAN network, there shall exist two end termination resistors, each of 120 ohms. Only the devices at the ends of the cable need a termination resistor.

Details of the 9-pin CAN-bus connector

Pin Name Description
1 n/c  
2 CAN_L Dominant low (signal)
3 CAN_GND Ground
4 n/c  
5 CAN_SHLD Optional shield
6 GND Optional looped ground
7 CAN_H Dominant high (signal)
8 n/c  
9 CAN_V+ Optional looped power

PSC-PB

Connect the PSC-PB to the profibus network using the 'daisy-chain' bus topology. Up to 32 devices can be connected in each segment of the profibus network. Each segment shall be correctly terminated by a 220Ω resistor between A-line and B-line (data lines). Powering of the 220Ω termination resistor ensures a defined idle state potential on the data lines, this is achieved by connecting a 390Ω resistor between +5V and B-line and another 390Ω resistor between A-line and GND (at the termination).
