13.1.2 Terminating the Last Sensor on the CANbus Link
The 2T sensor need not be installed in the numeric order of their address/sensor number (although it may be easier for later
maintenance). However, the last sensor in the chain must be terminated. All others must remain unterminated. We also
recommend that you make a record of the sensor numbers along with the name/number of the rack on which they are
installed. Figure 12.7 on the facing page, shows an example CANbus arrangement.
NOTE: To add sensors, unterminate final sensor, add sensors to the chain, and terminate the new final sensor.
