The radar output can be switched between the Navtech (Colossus) format and CAT-240 format via the Vertex user interface.
| Note |
|---|
Setting the output format is part of the radar operational configuration and can only be performed by an admin user. |
| Info |
|---|
Changing the output format only takes effect once the radar has been rebooted. |
To change the format to CAT-240:
...
Log on as an admin user. Select System Configuration:
...
...
Select the drop-down arrow in the Protocol field in the Data Output section:
...
...
Select CAT-240 from the Protocol drop-down:
...
...
Please refer to /wiki/spaces/PROD/pages/

...
A confirmation message will be displayed. Select Commit Changes:
...
...
A Data Applied Confirmation message will be displayed:

...
You will then need to reboot the system for the Data Output changes to take affect:

CAT-240 Output Example
Below is an example of the CAT-240 output:
...
Please note that CAT-240 FFT (video) data is not contoured.
Data Output Settings
IP Address: This is used in conjunction with the Sensor Port parameter and defines the endpoint that the UDP messages are sent to.
| Info |
|---|
If the IP Address specified is a multicast address (that is, an IP address between 224.0.0.1 and 239.255.255.255) this will enable multicast sending of the CAT-240 data to that address. |
Max Packet Size: This parameter specifies the maximum CAT-240 UDP packet size and is used to minimise potential problems of data loss when sending high-volume data over UDP.
| Info |
|---|
Message datagrams larger than the Max Packet Size will be split into smaller messages, with no message exceeding the Max Packet Size (although they may be smaller). |
| Note |
|---|
The default setting of 1400 will alleviate the data loss problem on most networks. However, the client (receiving) application will need to re-assemble multiple packets into a single azimuth of data. If the network configuration supports Jumbo Frames, the Max Packet Size may be set up to 9000 before packet loss may become a problem. Larger values increase the risk of data loss. |
