Adding Devices and IP Table Setup in SIMPL Windows
To add Ethernet devices to your program, in the SIMPL Windows' Configuration
Manager, drag an Ethernet device, e.g. a CEN-IO or a Virtual Touchpanel symbol,
into the program. Drop it onto the "Ethernet Units" arrow underneath the "Cresnet
Units" arrow. (If the arrow is not visible in the System View window, pull the
window divider down further.)
1. Double click on the icon and assign an IP ID and a corresponding IP
address in the tabbed configuration dialog titled "IP Net Address".
2. In the SIMPL Windows Program Manager, connect signals to the
"Virtual Touchpanel" symbol, exactly as you would to a regular wired
Touchpanel symbol.

Adding Ethernet Devices to a SIMPL Windows Program
.
When the SIMPL Windows program is compiled, the compiler creates an IP table
consisting of the IP IDs and the IP addresses for the various Ethernet devices. During
upload, choose whether to load this IP table or whether to use the table that already
exists in the CEN-TVAV.
Changing the IP Table via Crestron Viewport
You can modify the corresponding IP address for any IP ID without changing or
reloading the program by changing the IP table directly. From the Crestron
Viewport, select
Functions | Setup IP Table
then click the
Retrieve Current IP
Table from Control System
button. This will extract the IP table from the
CEN-TVAV and list it in the dialog box. Modify or delete existing entries or add
new ones. When all the necessary changes have been made, save the new table to
disk and/or load it back into the unit. Do not overwrite the IP table in the
CEN-TVAV the next time the program is uploaded, unless the addresses in the
program supercede those in the current IP table.

Crestron e-control™ IP Table Information
It is extremely important that the IP ID in the SIMPL Windows program match the
IP ID (sometimes called the Cres ID) encoded in the Crestron e-control Software
Development Kit (SDK) object by the developer of the Web page or Visual Basic®
program.
If more than one PC uses the same IP ID for a connection (e.g. each loads the same
Web page), the CNX Gateway will duplicate all packets that are received from the
CEN-TVAV to each of the identical IP IDs. This is known as touchpanel tracking.
The IP address that is typed into the virtual touchpanel devices in the SIMPL
Windows program is the IP address of the CNX Gateway, not of the individual PCs
(running a web browser or Active CNX application). This is because individual PCs
may change, but the CNX Gateway normally does not.
