The Tcp-Send Action allows you to select a device created in the device tab, and send it the info you define. The device value created in the device tab uses an IP address and port number of the device. This is used to create the TCP connection you send on. In the example above, the device Cinema Server Client is the IP address of a JNIOR and port number is the port number of the Cinema Server Client on the JNIOR. The text being sent to it is used to trigger a macro that was created and updated to the JNIOR in the support tool.
