1. NuDC-4U Overview
1.1. General Description of NuDC-4U
NuDC-4U is an innovative product that provides better solution for power
probing. Common DC power statistics including voltage, ampere and
even the watt can be read instantly via NuDC-4U. Moreover, up to 4 sets
of individual powers can be monitored simultaneously and the LCD
screen can also display the maximum and minimum value of the current
power during the test.
Besides displaying real-time power status, NuDC-4U can also record all variation of power status and
export it to PC via mini-USB port. When conducting long-time tests, NuDC-4U can automatically and
periodically save test logs to the folder in PC that users defined previously. Therefore, no testing data will
be lost during long testing periods. If the hardware fails, problems can be tracked down and analyzed
easily. Also, NuDC-4U can send e-mails to the user-defined e-mail address whenever an error occurs,
making it less likely for engineers to miss any crucial test results in a long testing time.
NuDC-4U has the ability to record 4,000 sample data within a second. However, in order to prevent PC
crash or lad caused by the enormous data flow, users can define the Display Rate with the utility software.
By defining Display Rate, users can set how many data should be sampled within 4,000 sample data
generated per second. Not only preventing PCs from crashing or lagging, but this feature also provides
more accurate maximum, minimum, and average values of the test.
For different testing requirements, NuDC-4U also has various optional accessories available. These
optional accessories include: USB interface for testing USB device power status, DC jack interface for
various sizes of the DC jack connectors, PoE interface for devices support Power over Ethernet, bare
wire connections for devices with no DC o4connectors, and mini daughter boards for PCB and SMD.

2. DUT Power Status Measurement
The following chapter will guide you with wiring/connecting your DUT with NuDC-4U and performing DUT
power status measurement.
Hardware Installation
There are several accessories provided for the connection to most of DC powered device. Please read
the instruction below.
2.1. Connecting NuDC-4U with PC
Connect USB port of NuDC-4U to PC or external power adaptor. If it is connected to PC, PC can control
and also provides power to the NuDC-4U.
2.2. Connecting NuDC-4U with PCB
Connect USB port of NuDC-4U to PC or external power adaptor. If it is connected to PC, PC can control
and also provides power to the NuDC-4U.
¾ Connection of ground pole
In the design of PCB, it should has ground PIN for the test purpose. All components use the same ground
(negative pole) and all ground conductors are linked together electronically. Connect the ground (negative
pole) to the ground connector of NuDC-4U. Several accessory daughter boards can be soldered on the
same PCB and use the same ground PIN.
¾ Connection of diagnostic channel
There are two conductors inside a channel port. Solder the two conductors (C&B) to the both side (Y&Z)
of the component under test by optional accessories. There is no difference if user swaps the sequence of
wire. For example, solder wire C to Y location and solder wire B to Z location.
ASSY-DC L0805, L1206, and L0603 are mini daughter boards with two soldering conductors for soldering
on PCB (printed circuit board). Two conductors of the accessory can be soldered on the surface of PCB.
The three accessories have different conductor width for testing on PCB with different width of soldering
points.

For PD device of PoE, Xtramus provides optional accessories ASSY-DC POEA, ASSY-DC POEB for the
test. It is a connection board for monitoring the power status of PSE device.
¾ PoE (Power over Ethernet): Power over Ethernet or PoE technology (commonly referred as IEEE
802.3af) describes a system able to transfer electrical power, along with data, to remote devices over
standard twisted-pair cable in an Ethernet network.
¾ PSE (Power Sourcing Equipment): Power Sourcing Equipment is a device (Ethernet Switch for
instance) that will be the power source in a PoE structure.
¾ PD (Powered Device): A powered device is a device powered by a PSE.
Connect this board between PoE switch and the PD device. After that, connect NuDC-4U in order to
monitor the power status.

2.5. Connecting NuDC-4U with DC Plug Socket Device
For DC powered device that has DC plug socket, Xtramus provides optional accessories ASSY-DC JACK
for the test.
ASSY-DC JACK is a connection board for monitoring the power status of devices with DC
jacks. The specifications of DC jacks may be different in core diameters. Before connecting ASSY-DC
JACK to the testing device, please be sure that the size of the DC jacks are matched.
Connect this board between power adaptor and the device that consume DC power. After that, connect
NuDC-4U in order to monitor the power status.
