**Parameters Set-up**:

- **PCAP**: Click **Start** and **Stop** to capture a certain range of data packets before clicking **Export** tab to export the data packets to your computer.
- **PCAP Auto Refresh**: To turn on or off the PCAP auto fresh function. If enabled, the PCAP will continue to capture data packets even after the data packets reached their 1M maximum in capacity. If it is disabled, the PCAP will stop data packet capturing when the data packet captured reached the maximum capturing capacity of 1MB.
