Product Description

The NXS is an ultra-compact, 24Vdc-powered, industrial PC platform, designed for DIN rail mounting. It provides

integral control, supervision, and network management solutions for wide variety of networked field devices. The

fanless design of the NXS incorporates an Intel®650 Mhz Celeron®processor and 512MB of system RAM. The OS

is Microsoft® Windows®XP Embedded, using either 1GB CompactFlash or a 40GB hard drive for storage (depending

on model).

The NXS uses DIN-mountable modules for power and UPS backup—refer to Table 1 for a summary and description

of onboard communications ports.

Although the normal operating mode for a NXS is “headless,” an onboard DVI/VGA port supports connection to a

CRT or LCD monitor (providing it has a DVI interface). A local console also requires connection of a USB-type

keyboard and mouse to the NXS USB ports.

Windows Notes

Regardless of NXS model, Windows “XP Embedded” is pre-installed on CompactFlash (W-NXS-AX-FL and CP-NXS-

AX-FL) or a hard drive (WEB-NXS-R2, W-NXS-AX-HD and CP-NXS-AX-HD ). No Windows CD is included. However,

a “Certificate of Authenticity” sticker is attached near the model number label.

Windows XP Embedded supports a “local desktop environment,” meaning the attachment of a keyboard, mouse, and

monitor. However, typical Windows access is done using a Microsoft “Remote Desktop” client connection to the unit,

as all models of NXS are factory-configured to support this. For related details, see “Local Console,” page 10.

Precautions are grouped into the following three categories:

•Safety Precautions

•Static Discharge Precautions

•General Precautions

Safety Precautions

The following items are warnings of a safety nature relating to the installation and start-up of the NXS controller. Be

sure to heed these warnings to prevent personal injury or equipment damage.

Warning • A 120Vac or 240Vac circuit powers the 24Vdc module (Power Supply) powering the NXS.

Disconnect power before installation or servicing to prevent electrical shock or equipment

damage.

•Make all connections in accordance with national and local electrical codes. Use copper

conductors only.

•To reduce the risk of fire or electrical shock, install in a controlled environment relatively free

of contaminants.

•

This device is only intended for use as a monitoring and control device. To prevent data loss or

equipment damage, do not use it for any other purpose.

Static Discharge Precautions

Static charges produce voltages high enough to damage electronic components. The microprocessors and

associated circuitry within a NXS controller are sensitive to static discharge. The following items are cautionary notes

that will help prevent equipment damage or loss of data caused by static discharge.

Caution • Work in a static-free area.

•Discharge any static electricity you may have accumulated. Discharge static electricity by

touching a known, securely grounded object.

•

Do not handle printed circuit boards (PCBs) without proper protection against static discharge.

Use a wrist strap when handling PCBs. The wrist strap clamp must be secured to earth ground.

General Precautions

Caution Do not install any expansion options (memory, PC/104 modules) apart from those already in the device,

or this

will void the warranty for the NXS

. Note that the NXS already contains the maximum

about of allowable system RAM, at 512 MB.

In cases where there is less than 22.1" available width, you can alternatively mount all three modules above the NXS,

as shown in Figure 6 on page 8.

Figure 6 Two DIN-rail mounting method B (alternate), all modules located above NXS.

There are two mounting methods for the NXS: DIN Rail Mounting and Wall Mounting.

DIN Rail Mounting

DIN rail mounting is the preferred method. The following procedure provides step-by-step instructions for mounting

the NXS on DIN rail.

Procedure 1 To mount on DIN rail.

Step 1 Position the NXS on the DIN rail, tilting to hook clamps over the top edge of the rail (Figure 7).

Step 2 Swing the device down fully onto the DIN rail, until both clamps completely latch.

Step 3

Mount other modules (Power Supply, NXS-UPS, Battery) onto DIN rail in the same fashion—see the

installation document shipped with each module for complete details.

Step 4 If needed, secure devices with DIN rail

end-clips

provided by the DIN rail vendor.

Figure 8 NXS dimensions with wall mounting brackets.

When mounting, ensure that a minimum of 3.94" (100 mm) clearance is maintained on all sides of the NXS from other

devices and/or enclosure walls. See “Space Requirements,” page 7 for more details.

Local Console

Typically, for initial software installation and commissioning, you access the NXS remotely, using NiagaraAX or

Niagara R2 software (Workbench platform connection or Admin Tool, respectively). In the case of applying Windows

updates or making Windows security setting changes, you connect remotely using the Microsoft “Remote Desktop”

software.

However, in some cases you may need a “local console” attached to the NXS, that is a keyboard, mouse, and monitor.

One example is after replacing the backup battery, to re-enter the BIOS setup data that was lost. Note that access of

the BIOS setup of a NXS is not possible over a network connection.

Please note the following about using a local console with the NXS:

•A USB type keyboard and mouse is required (no PS/2 type connectors).

•A DVI-capable display is needed, or a DVI-to-VGA adapter and a VGA monitor combination that has been

tested to work with the NXS.

•After attaching these items to the NXS, you must reboot the unit for local console operation.
