5.14.2. Main interface connection on RS-232
Below is shown the main interface (Port A) connection, using a full duplex RS-232 connection. The
recommended cable is a shielded AWG26 cable.
5.14.3. CAN Bus typical wiring
CAN bus is designed to operate with low cost twisted pairs cables. The bus may be terminated by a single
60 ohm resistor, or multiple resistors on each bus ends (as long as the equivalent parallel impedance is 60
ohm). This resistor is not present in the rugged processing unit.
