9. If necessary, set the terminating resistor.
Note: When using the connector with the last module on the network segment, one union nut
remains unused. Seal the union nut with the plug supplied. Refer to Figure 31.
10. If this connector is the end of the network, insert the rubber seal in the connector.
11. Tighten the union nut by two turns.
12. Insert the sealing plug in the unused union nut and rubber seal.
13. Tighten the union nut.
14. Set a terminating resistor at the last network connector to the ON position (see
Figure 32 and Table 11).
15. Plug the connector into the probe module.
