Hardware Installation 2.2 Execute Hardware Installation and Setting of PC/104-Bus Address The CAN-PC104/331 module can be used in all PC/104-compatible 16-bit systems (e.g. portable industry PCs or installed control systems). The carrier system will therefore be described by the general term ‘computer’ below. - Page 13 Additionally, the CAN_GND must be connected to earth at exactly one point in the CAN network. Use the special T- connectors and terminator connectors offered by esd. A CAN device whose CAN interface is not electrically isolated acts as an earth connection like the CAN_GND.

This is of great advantage, if the module is to be used in a narrow case. An adapter cable is contained in delivery of CAN-PC104/331-2-MicroMatch (Order No. C.2012.09). The cable with a length of 15 cm converts from micromatch connector to DSUB9. The DSUB-connector of the adapter cable corresponds to the standard assignment of a 9-pin DSUB- connector for CAN (see DSUB9-CAN-connectors). -

Therefore the practical maximum number of nodes, bus length and stub length are typically much lower. esd has concentrated her recommendations concerning CAN wiring on the specifications of the ISO 11898-2. Thus this wiring hints forgoes to describe the special features of the derived standards CANopen, ARINC825, DeviceNet and NMEA2000. -
