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.
NOTE: For more detailed information, refer to the SIMPL Windows help file by
selecting Help | Help Topics. Select the Index tab, type in IP Table, and then select
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 CNX-DVP4.
Changing the IP Table via 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 CNX-
DVP4 and list it in the window. 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 CNX-DVP4 the next
time the program is uploaded, unless the addresses in the program supercede those in
the current IP table.
NOTE: For more detailed information, refer to the SIMPL Windows help file by
selecting Help | Help Topics. Select the Index tab, type in IP table, and then select
Changing IP Addresses without Changing the Program.
For the CNX-DVP4 (or any Ethernet-enabled control system) to control devices via
Ethernet, the IP ID of the device must be associated with an IP address, and both the
IP ID and IP address must be entered into the IP Table of the control system.
You can create an IP Table in two ways. The first method is to double-click the
device in Configuration Manager to open the "Device Settings" window. Click the IP
Net Address tab and enter the IP address of the device in the IP Address field. Repeat
this procedure for all Ethernet devices in your system. This creates what is referred
to as a "default" IP Table. When the program is compiled and ready to be uploaded
to the control system, you will have the option to upload this default IP Table.
The second method is to use the Crestron Viewport. This method is especially useful
on site if you want to change one or more IP addresses without changing the
program. Refer to "Ethernet Setup" on page 17 for more information.
1. Select Functions | Setup IP Table.
2. Click Add and select the IP ID of the device from the drop-down list, then
enter the IP address.
3. When all the IP IDs and associated IP addresses have been added to the IP
Table, click Send IP Table to Control System.
