Once the SIMPL+ module is created, it can be uploaded to the device via the serial
or Ethernet port using the Crestron Viewport. Refer to "Appendix C: Uploading a
SIMPL+ Program" on page 35 for details regarding the loading of a program from
Viewport.
The SIMPL Windows programmer can implement this device in their system by
adding a generic e-control touchpanel symbol to their program, then reading the
documentation generated by the OEM designer to determine what join number maps
to what function on the device. Refer to "Programming with SIMPL™ Windows
on page 20 for details.
3. Web Browser Control of a Device Through the eServer
Utilizing PC-based Web Server and Crestron CNX Gateway
Software
Compared to the two previously mentioned configurations, this one is less common.
This configuration allows the customer's device to interface to a web server and GUI
web pages stored and running on a local PC. Although there are many reasons a
designer may choose this configuration, the primary cause is for security. For
example, if the objective is to control a projector through the Internet and not to
expose the eServer web server to the Internet, the designer can use a standard PC
web server. Such an arrangement also allows for more than the 2 MB of flash
memory limit of the eServer for web pages. In this configuration, web page files are
stored on file system in the PC.
The eServer designer can create one SIMPL+ module and one set of e-control web
pages. Then it is up to the end user to decide if they wish to run in "embedded web
server mode" (refer to configuration # "1.Web Browser Control of a Device Through
the eServer" on page 7) or "external web server mode".
