Current Version: 1.7

The CSI Web Server software package includes the CSI Web Server, CSI Web Server Administrator, and the Web Publisher. The CSI Web Server runs on a PC and displays projects created using RTMC or RTMC Pro in any web browser that supports HTML5. The Web Server Administrator allows you to configure or check the status of the Web Server, and easily browse to one or more websites running on the Web Server. The Web Publisher is used to publish your RTMC or RTMC Pro project to either a PC website running the CSI Web Server or to an HTTP-enabled data logger such as a CR6 or CR1000 with an NL120 attached. (Publishing to a data logger requires an RTMC Pro project.) In addition, the Web Publisher has display settings that allow you to show other tabs for data browsing and network status.

The CSI Web Server package is included with RTMC Pro. It can also be purchased separately for use with the standard RTMC Development application that is bundled with LoggerNet, LoggerNet Admin, and RTDAQ.

Additional Compatibility Information


CSI Web Server is optimized for using projects created with the RTMC 4.x development tools (standard RTMC Development or RTMC Pro). Although CSI Web Server can use projects from version 2.x or 3.x development tools, the web display may look different than what’s expected. For best performance, RTMC version 4.x development tools should be used to develop projects for CSI Web Server.


CSI Web Server runs on Windows 10 and 11. CSI Web Server runs on both 32-bit and 64-bit versions of these operating systems.
