B-8 Quick Start For the 1738-ADNX
To properly terminate the 1738-ADNX when using a Subnet,
refer to the illustration.
• If you are not going to use the Subnet, you must still
terminate it!
• Note that the non-terminating base is shipped with the
1738-ADNX only. The terminating base is shipped with all the
other ArmorPoint DeviceNet adapters.
• Do not use carbon resistors. Metal film is recommended.
Continue ONLY after you have verified that the taps are
terminated correctly.
20. Double click on the 1738-ADNX to open the properties window.
