•
IP Address: The multicast IP address to which the devices send/receive the WT messages. All the devices
in the same subnet must subscribe to the same multicast IP address so they can listen and talk to other
devices on the subnet.
•
Port: The base port on which the device receives the text messages. All the other WT (voice message)
channels listen on port numbers relative to this port.
•
Channel increment: Defines how the WT channels are incremented relative to the base multicast address
or base port. If the increment type is set to port, the device listens on the port number next to the base port
number for Channel 1. For example: if the base port is 5000. If the channel increment type is set to port, the
device listens on port 5001 for Channel 1, port 5003 for Channel 3, etc. Note that the device subscribes to
only one Multicast IP address.
The device sends the WT messages to the same multicast address (base multicast address), but listens to
different channels on different ports.
If the increment type is set to IP address, the device subscribes to multiple multicast addresses for the
different channels. For example: if the base Multicast IP address is 239.192.2.2. and the channel increment
type is set to IP address, the device subscribes to IP address 239.192.2.3 for Channel 1, 239.192.2.4 for
Channel 2, etc.
The device sends the WT messages to different multicast addresses for different channels, but listens to
different channels on the same port (base port).

DownloadFiles
The UCAClient has the capability to download files from an http server to the CA50 device. This is useful when
downloading custom .wav files to be used with notification or business applications.
Information about the files to download can be provided in the profile xml as follows:
<DownloadFiles DownloadAtStartUp="Y">
<File HTTPURL="" PathOnDevice="" Overwrite="N"/>
<File HTTPURL="" PathOnDevice="" Overwrite="N"/>
<File HTTPURL="" PathOnDevice="" Overwrite="N" />
</DownloadFiles>
Attributes:
•
DownloadAtStartUp="Y" - Select "Y" to download the files at user logon.
•
HTTPURL - Source file location and name.
•
PathOnDevice: - Destination (path on the CA50 device). The path on the CA50 device where the
files are downloaded is "\Application\Download\".
•
OverWrite="N" -Select "Y" to overwrite the existing file on the CA50 device, if applicable.
Example Usage:
<File HTTPURL="http://server.somecompany.com/Response.wav" PathOnDevice="" Overwrite="N" />
Source = "http://server.somecompany.com/Response.wav"
Destination = "\Application\Download"
<File HTTPURL="http://server.somecompany.com/Wav/Response.wav" PathOnDevice="\Wav\"
Overwrite="N" />
Source = "http://server.somecompany.com/Wav/Response.wav"
Destination = "\Application\Download\Wav\"
