124 Chapter 4 Networking 882s
Overview
This chapter describes how to use the 882 in a networked environment.
Quantum 882 generators can operate and be administered over an Ethernet LAN
connection. By networking multiple 882s together, you can centralize control in production
environments.
When networking 882s, a file server containing a set of system and resource files is
installed on the network. This arrangement allows you to:
• Set up 882s to automatically retrieve and use a centrally-stored set of system and
firmware files upon startup. This ensures that each 882 on the network is running the
same firmware.
• Set up 882s to access a common set of objects, such as images and formats, from a
file server. This allows each 882 on the network to access the same set of standard and
custom library files.
• Easily upgrade a 882’s local system and library files from the file server. This ensures
that each 882 on the network is using the most current system and library files when
booting and accessing files locally.
• Control and maintain your network of 882s remotely from a single host PC. You can
manage the 882s through the command line interface, through the Virtual Front Panel
in a Web browser, or by transferring files using the 882 FTP Browser.
882 file system
The 882 generator file system is comprised of two main directories (folders): 1) System
and 2) Library. The System folder contains the realtime operating system and firmware file
(vxWorks) and the gateware. The Library folder contains the following resource files:
• Fonts - Object files used to define the font types.
• Formats - XML files defining the format parameter settings.
• FormatLib - XML files for configuring the source list of formats
• Images - C++ object files, executables, bitmaps, and XML files for rendering images.
• ImageLib - XML files for configuring the content list of images
• Sequences - XML files with instructions for test sequences.
• Users - XML files for user configuration profiles
