6.3. CAN bus terminating resistor
In order to enhance the reliability of CAN communication and eliminate the reflection interference of the CAN bus
terminal signal, the two farthest end points of the CAN bus network are usually added with a terminal matching resistor,
and the value of the terminal matching resistor is determined by the characteristic impedance of the transmission cable.
For example, the characteristic impedance of the twisted pair is 120Ω , then the two endpoints on the bus should also
integrate 120Ω termination resistors.
Note: ECAN-U01S has integrated 120Ω terminal resistance, you can choose whether to connect the resistance to the bus
through the DIP switch, the DIP switch is next to the 6pin terminal, R1 , R2 correspond to the terminal resistance of
CAN1 , CAN2 , dial to ON position to enable the resistor.
7. Function details
7.1. Save data and real-time save function
The user can save all the data in the current send / receive list to the local. The save format is shown in the following
table:
file type
file format
editor
Text file
.txt
notepad
The text file is convenient for data preservation, and can be formatted and imported into excel for later analysis.
Click " Real-time save " on the toolbar , set the text type and file name of the real-time save, and then start the data
real-time save function (ie, set the save node A ), click again (ie, set the save node B ), the system will stop saving, All
