AMX NXA-PCI80211G Unsecured Panel Access using a Dhcp Address, Replacing the NXD Outer Housing

NXA-PCI80211G Installation into Modero NXD Panels

Upgrading the 802.11g card within a WallMount panel involves removing the rear plastic outer housing (back box), installing the new 802.11g wireless card, and then placing the back box back onto the NXD panel, as described below.

Step 1: Removing the existing NXD Outer Housing

1.Carefully detach all connectors from the side of the touch panel and remove the front magnetic faceplate from the NXD unit by firmly gripping the faceplate and pulling outwards, while applying a small amount of pressure to remove it from the main unit.

2.Place the LCD facedown onto a soft cloth to expose the under-side of the unit and prevent scratching of the LCD.

Note: DO NOT REMOVE THE PANEL SECURING SCREWS. These screws secure the LCD to the metallic casing.

3.Unscrew the Stereo Output nut from the Stereo Output jack.

4.Remove the I/O connector plate by using a grounded Phillips-head screwdriver to remove the two screws and slide the I/O connector plate away from the back box housing (FIG. 3).

2.	Insert and secure the four pan-head Housing Screws into the pre-drilled

3.	Reinstall the existing connector plate by aligning all connectors to their
	respective locations.

Unsecured Panel Access using a DHCP Address

Communication from the panel can be direct (using an Ethernet cable) or indirect (through the wireless card communicating to the Wireless Access Point (WAP)). In determining the method of communication, the panel always defaults first to the direct Ethernet communication. If no direct connection is detected, the panel then checks to see if there is an installed wireless card and then communicates to the WAP using the Wireless Settings assigned within the Wireless Connection page. The wireless interface card (installed within the

5.Unscrew the four pan-head Housing Screws from the rear of the NXD unit (FIG. 3) and gently remove the outer housing. These screws secure the back box to the internal panel casing.

Step 2: Installing the mini-PCI Wireless Card

1.Discharge static electricity from your body by touching a grounded metal object and locate the mini-PCI card connector on the main board (FIG. 4).

Note: If you have previously installed an NXA-RGB card, it must be removed to gain access to the mini-PCI connector on the board.

2.Carefully remove the terminal ends of the antenna from their factory default connectors on the main board.

3.Firmly grasp the NXA-PCI80211G mini-PCI card (from the edges) and insert the pins (at a 25° angle) into the opening on the connector (FIG. 4).

4.While maintaining the 25° angle alignment on the new module, push it in firmly until the contact pins are completely inside the connector and the card "snaps" into place (FIG. 5).

5.Push the card downward (towards the main board) until the side braces snap atop the NXA-PCI80211G and hold it in place.

6.Locate the terminal ends of the antennas and apply downward pressure to "snap" them onto their gold-tipped counterparts on the card. Carefully push down on each connector to verify it is securely joined to the card.

Note: It is recommended that any upgrade of internal equipment be done simultaneously in order to reduce the risk of damage to internal components.

Step 3: Replacing the NXD Outer Housing

1.Once the card has been securely installed, gently place the outer housing back onto the metallic panel casing (with the connector opening on the right-side of the panel) and align the four pan-head Housing Screw holes along the edges of the outer housing.

panel) must match the WAP communication parameters.

1.Complete the previous installation procedures.

2.Power-up the panel and navigate to Protected Setup > Wireless Connection to open the Secondary Connection page.

3.Toggle the DHCP/Static field (from the IP Settings section) until the choice cycles to DHCP. Except for the Host Name, all other fields are then greyed-out.

4.Press the optional Host Name field to open a Keyboard and enter the Host Name information.

5.Press Done after you’re finished assigning the alpha-numeric string.

6.Do not alter any of the remaining greyed-out fields in the IP Settings section. Once the panel is rebooted, these values are obtained by the unit and displayed in the DNS fields after power-up.

Note: This information can be found in either the Workspace - System name > Define Device section of your code (that defines the properties for your panel), or in the Device Addressing/Network Addresses section of the Tools > NetLinx Diagnostics dialog.

7.Touch the Network Name (SSID) field and from the Service Set Identifier keyboard you must enter the SSID name assigned to the target WAP (case sensitive). Do not leave this field blank.

•One of the most common problems associated with connection to the WAP arises because the SSID was not entered properly. You must maintain the same case when entering the SSID information.

As an example: ABC is not the same as entering Abc or abc.

8.Toggle the Authentication field between Open System or Shared Key.

•Open System Authentication allows any device to join the network if the panel’s SSID matches the WAP’s SSID. This is default setting.

•Shared Key Authentication requires that the panel and the Wireless Access Point have the same WEP Key to authenticate.

9.Toggle the Encryption field until it reads Clear Text (default).

10.Verify the IP Settings section fields have been properly set.

11.Press the Back button to navigate to the Protected Setup page.

12.Press the on-screen Reboot button to both save any changes and restart the panel.

13.After the panel restarts, return to the Wireless Connection page to verify the Link Quality and Signal Strength.
