Any JACE-NXT uses Windows XP Embedded (XPE), pre-installed as the operating system. No Windows CD is included. However, a Windows “Certificate of Authenticity” sticker is affixed near the model number label. When ordered with NiagaraAX, the OS is installed differently, depending on model:
-
NXT-AX-FL model: 2GB CompactFlash. This flash drive has 3 partitions:
-
C: System (996MB) — has the Windows OS
-
D: Niagara (800MB) — with NiagaraAX release folder, subfolders for station database and graphic files
-
History (156MB) — for the station’s NiagaraAX history space.
A flash-based JACE-NXT uses an EWF overlay filter, which affects commissioning and maintenance. For details see Notes on EWF (Enhanced Write Filter) in Windows XPE.
-
-
NXT-AX-HD model: 250GB hard drive, as an alternative to the CompactFlash-based model.
Windows XP Embedded on either JACE-NXT model supports a “local desktop environment,” meaning the attachment of a (USB) keyboard, (USB) mouse, and (DVI-I capable) monitor.
Although a local console is supported, the usual method to apply Windows updates (and/or make changes in Windows security)
is to access the JACE-NXT via a “Remote Desktop Connection”, using Microsoft’s “Remote Desktop” client software. This is usually installed on any PC with Windows XP or later.
On any JACE-NXT, Windows XP Embedded requires periodic updates to ensure proper security. This can apply even to a new unit. See JACE-NXT Windows XPE security for more details.
