NXA-WC80211GCF Card and Antenna Overview
This upgrade kit requires that pre-existing panels first be removed from their
current location (surface, wall or docking station) before an installer can access
the internal circuit boards and upgrade a pre-existing 802.11b wireless CF
card.
MVP panels require the use of a cardboard cutout (Mounting Template) to
properly position the metal antenna plate onto the inner surface of the unit's
rear plastic housing.
CV7 and CV10 panels only require locating the Compact Flash's metal cover
plate on the main circuit board and then adhering the terminal antenna
connector to that location using the included double-sided adhesive tape.
Note: If the CF metal cover plate is not present over the wireless card slot on a
CV7 or CV10 panel, you can use the adhesive tape to secure the terminal
antenna to the surface of the new card (atop the product label).
The procedures for upgrading a CF card on an MVP is identical for both
MVP-7500 and MVP-8400 panels. The procedures for upgrading/installing the
new CF card are also similar across all referenced NXT panels and NXD
panels as a group (differences arise from their housing).
NXA-WC80211GCF Installation into MVP Panels
Upgrading the wireless CF card on an MVP involves opening the panel
enclosure, removing the existing card, replacing it with the upgrade, and then
closing the panel enclosure, as described below.
Note: Batteries should be removed prior to upgrading the card.
Step 1: Access the MVP's Internal Components
1.
Carefully detach any connectors from the touch panel and then gently
place the MVP LCD facedown onto a soft cloth to expose the battery
compartment. This step helps prevent scratching of the LCD.
2.
Slide the Battery Compartment cover (FIG. 2) away from the metal plate
to expose the internal battery compartment (2 battery slots).

3.
Remove any previously installed MVP-BP batteries prior to removing the
outer housing.
4.
Use a grounded Phillips-head screwdriver to remove the two housing
screws shown in FIG. 2. Once done, place these screws aside.
5.
Grasp the bottom rim of the outer housing (just above the MVP interface
connector -
Blue arrows
in FIG. 2) and in a single motion, carefully pull
the bottom rim up and then out (away from the IR Emitter) to expose the
internal circuit board (A in FIG. 2). It might be necessary to repeat this
process along the bottom and sides of the housing as well.
6.
Remove the dark grey trim from the top rim of the board (FIG. 2).
7.
After you have completed the upgrade process, complete the installation
by continuing to Step 3: Close and Re-secure the MVP Panel
Enclosure section on page 3.

Step 2: Install the new 802.11g CF Card and Antenna (MVPs)
1.
Discharge any static electricity from your body by touching a grounded
metal object and then locate the wireless card slot on the main board
(FIG. 3).
2.
Place the circuit board (A in FIG. 2) on a flat level surface so that the IR
Emitters are pointing away from you.
3.
Insert the tip of a grounded flat-head screwdriver into one of the card
removal grooves (located on either side of the existing CF card), and
gently pry it out of the slot. Repeat this process on the opposite card
removal groove. This alternating action causes the pre-existing card to
"wiggle" away from the on-board connector pins.
4.
Slip your finger into the gap (between the card and the circuit board),
firmly grab the old card by its sides, and then carefully pull it up and out
from the slot. An angular removal of the card is required because one of
the housing's latch attachments blocks the slot opening.
USE CARE WHEN PULLING UP ON THE CARD.
5.
Flip over the MVP's rear housing (B in FIG. 2) so that the internal support
structures are visible and then lay it directly in front of the circuit board
such that the battery compartment is furthest away from you. This
placement provides contact of both top rims (FIG. 3).
6.
Remove one of the included alcohol pads and use it to thoroughly clean
both the rear housing's inner surface (bottom right corner) and the
underside of the terminal antenna's metal pate (FIG. 1). These surfaces
must be properly cleaned to provide good adhesion for the later
installation of the wireless antenna.
7.
Place the included Mounting Template cutout along the bottom right
corner of the rear housing (FIG. 3). Use the housing's inner support
structures to fix the template into place.

9.
Grip the sides of the new wireless card and insert it firmly into the slot
opening (at a downward angle) until the contact pins are completely
inside the card and securely attached to the pin sockets.
Note: You must precisely align the double-sided tape to the surface of the
terminal antenna's metal plate in order to later secure the antenna within
the pre-defined installation area outlined by the included Mounting
Template.
10. Carefully peel-off one side of the included double-sided tape and adhere
the adhesive side to the surface of the antenna's metal plate.
11.

12. Grip the antenna by its sides and carefully peel-off the remaining
protective film on the double-sided tape.
13. Align the antenna into the long vertical groove in the cutout and firmly
adhere it to the inner surface of the housing. Make sure the wire is
threaded along the left side of the cutout, this helps in the removal of the
cutout.
