Bus Transceiver SN65HVD230 CAN Communication Module, for Arduino
Key features and PIN function
The ARD-621 with SN65HVD230 can be used in a high interference environment. The device has the ability to send and receive at different rates, and its main features are as follows:
Fully comply with ISO11898 standard;
High input impedance, allowing 120 nodes;
Low current standby mode, typical current is 370μA;
Signal transmission rate up to 1Mb / s;
Thermal protection, turn on the fail-safe function;
Bus with anti-torque interference protection function;
Slope control to reduce radio frequency interference (RFI);
Differential receivers have extensive anti-common mode interference and electromagnetic interference (EMI) capabilities.
Operating mode and control logic
The SN65HVD230 has three different operation modes: high speed, inclined plane and waiting. The control method can be realized through the control pin. Figure 2 is a typical application diagram in the SN65 HVD230 CAN bus system. It can be seen from the figure that the CAN controller is connected to the data input terminal D of the output pin TX SN65 HVD230. This CAN node can send data to the CAN network; the RX and SN65 HVD230R data output of the CAN controller and the receive pin End coupling to receive data. Choose Sn65HVD230 RS port through jumper wire and grounding resistance at one end, you can choose 3 kinds of operation modes through hardware, among which slope is 0 ~ 100K resistance potentiometer
