NXA-BASE/B Battery Base and Accessories

For more detailed installation and operating instructions, refer to the touch 
panel’s instruction manual, available on-line at www.amx.com.     

Overview of the NXA-BASE/B

The NXA-BASE/B (Battery Base) is a Modero accessory that allows a touch 
panel to function off the collective charge of two internally connected NXT-BP 
batteries (FG2255-10). The base provides both power and battery information to 
the panel via the panel interface connector (FIG. 2). 
This base is also sold as part of an NXA-BASE/B Kit (FG2255K) that contains 
one (1) battery base and two (2) batteries. The accompanying batteries can be 
charged through either the base or optional NXT-CHG Modero Power Station 
(FG2250-50). Refer to the 12" and 15" Modero Touch Panel Series Owner/
Reference Manual for more information.

Installing the NXT-BASE/B to an NXT Modero Panel

1.

Power Off the panel before attempting to use the NXA-BASE/B.

2.

Place the empty battery base onto a flat/level surface.

3.

Verify the alignment of the Panel Interface connectors between the panel 
(male connector) and base (female connector) (FIG. 2).    

4.

Carefully place the Modero panel over the base alignment pegs (FIG. 3). 
These pegs assist in aligning the panel to the base.  

5.

Gently apply downward pressure until the panel is securely mounted to the 
battery base. 

6.

Firmly grip both the panel (from side) and battery base (from below).

ATTENTION! The battery base CANNOT be "hot-swapped". A panel 
receiving power through a connected PSN6.5 cannot have a Panel 
Interface connector from the battery base inserted into the bottom of the 
panel. POWER OFF the panel before installing the NXA-BASE/B.
7.

Gently place the touch panel LCD facedown onto a soft cloth. This 
prevents scratching of the LCD while the battery base is secured.

8.

Locate the captive fastners on the underside of the battery base (FIG. 4) by 
angling the base combo slightly forwards.    

9.

Push down on each fastener head by using a flat-head screwdriver to turn 
them clockwise until the NXA-BASE/B is securely attached to the 
underside of the NXT Modero touch panel. 

10. After securing is complete, firmly grip both the panel LCD/base combo and 

gently place the unit back onto a flat surface.
