• The case contains 1 panel of 8 Data Management ports.
o The panel is supplied by a 12vdc power supply.
o Power supplies: 90-264vac, 50/60Hz
o 2 cooling fans keep the power supplies ventilated.
o The panel has 8 ethernet ports which correspond to the 8 panel cup connectors.
o The 8 ethernet ports connect to a built in ethernet switch which in turn connects to the
external ethernet port of the Portable Case. This is used to connect to the NuScribe
computer ethernet network.
o A clear plexiglass cover allows a view of the LEDs on the built in ethernet switch for
connectivity indication.
o The Data Management ports are hard plastic cups with:
▪ 4 springs on the USB model panels. 2 springs are used for turning on and
charging the NRU during upload and commissioning, and 2 springs are used for
USB data communications during upload and commissioning. or
▪ 2 springs on the optional TransferJet panels that are used to contact the NRU
MIM for turning on the NRU prior to offloading or programming and providing
charge voltage during offloading or programming.
▪ On this panel model each Data Management port has a TransferJet antenna
built into the base, which communicates with the NRU for offloading and
programming.
• The case contains 2 panels of 8 charging ports.
o Each panel is supplied by a separate 12vdc power supply.
o There is enough redundancy in the power supply loads, that 1 power supply can run 2
panels of charging ports. If a power supply goes bad, the corresponding panel can be
moved over to a good power supply.
o Power supplies: 90-264vac, 50/60Hz
o 2 cooling fans keep the power supplies ventilated.
• The charging ports are open-sided hard plastic cups with 2 springs that are used to contact the
NRU MIM for supplying voltage to the internal NRU battery charger.
