3. Referring to Table 13.3 below , and using the non-conductive tool, set the DIP switches for each sensor to its
number in the chain (from sticker applied in step 1 ).
Figure 13.5 below , shows a representation of the DIP switches.
4. Confirm that the DIP switches are set correctly for each sensor, and replace the housing cover if necessary.

13.2.2 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 un-terminated. 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 13.6 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.
