Crestron Control 
Crestron control is defined as an interface to a Crestron Ethernet device. 
Implementation of this method is necessary for a device to communicate with a 
Crestron control system. Use of this interface method does not place design 
limitations on the project. For example, a device can implement a Crestron control 
system interface, have a web interface, and have a custom PC application 
communicating to the same eServer. Refer to configuration # "2. Crestron Control 
System Control of a Device Through the eServer" 
on page for details of this 
interface method.  
Non-Crestron Control 
Non-Crestron control is defined as control and monitoring of equipment through any 
web browser or custom application. Since the eServer has many applications outside 
the audio-video industry, a designer can use the device without other Crestron 
devices. As a result, the only interface necessary is a web browser or a custom 
application built by an OEM designer. Use of this interface method does not place 
design limitations on the project. For example, Crestron tools such as VisionTools™ 
Pro-e, the e-control™ Software Development Kit (SDK), and SIMPL+ can be 
utilized to build the project, but no Crestron device or software is needed to 
communicate with the box. Refer to the next section for multiple configuration 
possibilities of this interface. Only one (configuration # "2. Crestron Control System 
Control of a Device Through the eServer" 
on page 8) of the five configurations 
presented does not apply.  
Choose the Configuration 
The second question to answer when deciding to incorporate an eServer into a 
development project is which configuration should be used. The configuration 
depends on the application. Any combination of the configurations listed below are 
permissible with the eServer. Although most projects would probably utilize only 
one configuration to simplify development, using more than one configuration at the 
same time is generally allowed. The only exception is #5. Opening a TCP connection 
while utilizing #1, 2, 3, or 4 temporarily suspends configuration 1, 2, 3, or 4 until the 
TCP connection is closed.  
1  Web browser control of a device through the eServer  
2  Crestron control system control of a device through the eServer  
3  Web browser control of a device through the eServer utilizing PC-
based web server and Crestron CNX gateway software 
4  Custom application control of a device through the eServer utilizing 
Crestron ActiveCNX control 
5  Custom application control of a device through the eServer utilizing 
standard TCP/IP sockets. 
Implement the Chosen Configuration 
1.Web Browser Control of a Device Through the eServer  
This configuration permits any standard web browser to become the interface for the 
device. For example, the IP address for the eServer dedicated to the switcher can be 
entered into a web browser. If designed properly, the resultant screen shows the 
current state of the device. The device interface on the web page can allow real-time
