Power Requirements
The NXU-2A is designed to operate from a n12V DC supply. The unit will meet all
of its specifications over a voltage range of +11 to +15 VDC and will be damaged by a DC
source that delivers a constant (non-transient) DC voltage above this range. The DC power
consumption is 500 mA maximum. The AC adapter provided with the unit meets these
specifications.
NOTE:
Use only the Class 2 power supply provided with the equipment.
REMARQUE:
Utilisez seulement la Class 2 de la generation electrique qui est
inclus avec l'equipement.
The NXU-2A is a microprocessor-controlled device. As with any such equipment, a very short
loss of power can cause operational problems and/or cause the unit to reset. The
communications link will be inoperable during the reset period. JPS recommends the NXU-2A
and associated equipment be connected to an AC power source that utilizes an uninterruptible
power system (UPS). If the overall site does not have UPS capability, the NXU-2A should be
plugged into a smaller UPS, such as those used for personal computer systems

Installation Checklist
Table 2-1
Basic Installation Checklist
Determine NXU-2A network parameters
such as IP address, subnet mask, and
gateway address.
You must assign these values. If you are not sure
how to determine these values, see the network
administrator for your organization.
Provide suitable power for the device.
See section 2.6 Power Requirements.
Make interconnections.
See Section 2.8.2 Audio Level Adjustment
Potentiometers and Input Test Point for External
Interconnect Information.
Configure NXU-2A parameters.
See Section 3 Configuration.
Adjust audio levels.
See Section 4.4.2.

Rear Panel Adjustments and Connectors
Refer to Figure 2-2 for a view of the NXU-2A Rear Panel. All rear panel connectors and
adjustment potentiometers are explained in the section below, starting at the left side of the
panel.
2.8.1
DC Input Connector, J6
The NXU-2A operates on a n12 VDC. The power is applied through J6 via the “Wall
Cube” AC adapter provided with the unit.
