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 AWG 26 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 Ω resistor, or multiple resistors on each bus ends (as long as the equivalent parallel impedance is 60 Ω).
This resistor is not present in the rugged processing unit.
