Bosch Motorsport Data Logger C 70 Manual 5/112
2 Communication channels
CAN bus
The C 70 has two CAN buses configurable as input and output. Different baud rates are
selectable. Please note that the C 70 does not contain any CAN termination resistors. Thus
the CAN termination resistors need to be integrated into the wiring loom.
Ethernet channels
The C 70 has one 100 MBit full duplex Ethernet communication ports. The port is intern-
ally connected with an Ethernet switch. The Ethernet ports have 'cable auto crossover'
functionality.
RS232 ports
The C 70 has two RS232 serial ports. Baud rate for both ports is programmable. RS232
port 1 is reserved for online telemetry, port 2 can be used for reception of data from a
serial GPS receiver.
Vehicle diagnosis connector
The Bosch Motorsport vehicle diagnosis connector is used as a standard interface to con-
nect the vehicle to a PC e.g. via a MSA-Box II. Loom connector: AS0-12-35SN
