Crestron e-Schedule Programmer’s Guide
NOTE : Crestron runs a demonstration e-Schedule program at
http://www.escheduler.crestron-econtrol.com . To gain access, type “guest” as
both the User ID and password.
Tiered Switching
e-Schedule does not currently support tiered switching, i.e., any environment
that does not offer full crosspoint capability. For the e-Schedule system to
function properly it must be able to switch any source to any destination
without interfering with the routes of other sources or destinations or
requiring allocation of a limited number of intermediate channels.
System Components and CNX Gateway Licensing
The e-Schedule software package consists of the following:
•
Active Server Pages —Web server application for scheduling
and conflict checking.
•
Real-Time Engine —application for controlling media resources
and signal routing between control systems, source devices and
destination devices.
•
e-Schedule Database Directory —divided into four categories:
1) Configuration 2) Web Browser 3) Resource and 4) System.
•
Documents/Examples Directory —various SIMPL Windows
and VT Pro-e programs that define an extensive sample system.
Together with the completed configuration databases (also
included), the programs can be used as models for most projects.
In addition, the system requires a CNX Gateway (the software gateway, not
the card gateway) to enable Ethernet communication with
Crestron equipment. The number of connection licenses depends on the
configuration of the system.
Crestron recommends two possible software configurations. The first is to
have all the software and the CNX Gateway on a single computer. In this
case, the number of connection licenses will be equal to the total number of
IP addresses (meaning all browsers and any hardware with unique IP
addresses),
plus two . The two extra licenses enable communication between
the Web Server and Real-Time Engine applications. For example, in the
following system:
•
One CNMSX-Pro controlling various sources
•
Five CEN-TVAVs
•
Five Web browsers
A total of thirteen licenses would be required.
The second possible configuration is to have two computers, one for the Web
Server and the other for the Real-Time Engine, each with its own CNX
Gateway. (The Database Directory should be installed on the Web Server for
efficiency.) The Web Server computer would then require licenses for all
