Connecting Door Phone
The Door Phone port is available as an optional module on the ETERNITY NE. The Door Phone module contains a
Door Phone Port and a Digital Output Port, providing the interface for connecting and operating a Door Phone and
a Door Lock Release Device with the ETERNITY NE.
Installing the Door Phone Module
• Unpack the Door Phone module and verify package contents.
• Make sure power supply is turned off before you begin installation.
• Unscrew and remove the top cover of the enclosure. Keep the screws and the cover aside.
• Locate the connector of the Door Phone module on the mainboard. Remove the screws on the studs for
the module and keep them aside.
• The slot for the Door Phone module is located on the back panel and is covered with a flap. Use your
finger to press the slot cover from the outside of the side panel of the enclosure, and release the flap.
• Now, grasp the flap from inside the enclosure and pull up the flap.
• Gently seat the Door Phone module on the connector on the mainboard such that the RJ45 connector of
the module is aligned with the slot, and the connector pins on the module make complete contact with
those on the mainboard. Do not apply pressure.
• When the module is seated firmly on the connector on the mainboard, secure the module with the screws
on the studs.
• If you have no other module(s) to install, replace the top cover and secure the cover with the screws.
