6. Question How do I configure the transfer rate at the bus converter Answer Not at all The PCAN B10011S doesn t convert the incoming data with regard to timing Because of this it doesn t have direct influence on the transfer rate This is determined by the nodes of the connected CAN You should make sure to use the same transfer rate for both the connected HS CAN component and all nodes in the Truck Trailer CAN 16 l PCAN B10011S User Manual PEAK 6 Technical Specifications System Supply voltage Current consumption HS CAN Truck Trailer CAN Transfer rate Degree of protection EMC directives Operating temperature Temperature for storage and transport Relative humidity Size Weight 24 V DC nominal 8 30 V DC possible about 35 mA at 24 V max 110 mA ISO 11898 2 Sub D socket according to CiA DS 102 Transceiver Philips PCA82C251 Internal bus termination with 120 Q switchable ISO 11992 Sub D plug Transceiver Atmel B10011S Modes Master and Slave active and passive max 125 kBit s IP20 EN 55022 1999 EN 55024 2002 EC directive 73 023 EWG EC directive 89 336 EWG EC directive 91 263 EWG EC directive 92 031 EWG EC directive 93 068 EWG 40 85 C 40 185 F 40 100 C 40 212 F 15 90 not condensing about 79 x 43 x 22 mm 3 1 8 x 1 11 16 x 7 8 inches max 50 g 1 8 oz Design and specifications are subject to change without no
