Head Network Setup dialog box
The Head Network Setup dialog box allows you to change the Sonar Head network parameters, such as the IP address.
How to open
This dialog box is opened from the Setup menu.
Note
This dialog box is only available when the Sonar Head is connected and paused. To pause the Sonar Head, click SetupConnect, then open the Menu Widget in the top-right corner of the sonar view. Click Pause.

Description
You can program the IP address and the IP port of the Sonar Head for various network environments. The factory default IP address is 192.168.1.234, and the default port number is 30.
To change the Sonar Head IP address, click Read from Head to get the information from the Sonar Head. Edit the fields, then click Write to Head.
Details
Head Name
The name assigned to the Sonar Head. You cannot change this parameter — it is read only.
Serial Number
The unique serial number of the Sonar Head. You cannot change this parameter — it is read only.
Automatic IP address allocation
Determines whether the Sonar Head can be assigned an IP address from a DHCP Server. By default, the Sonar Head uses a static IP address. You cannot change this parameter — it is read only.
VDSL Profile
The VDSL2 standard defines various profiles that can optimize the data rate and link performance on cables of different quality and lengths. For longer cables, you may wish to use a profile with a lower bandwidth, such as profile 0 (8b) or 1 (12a).
The following profiles are available:
•  0 (8b): Suitable for long or low-quality cables, but has a slower data rate.
•  1 (12a): A good compromise for medium-length cables, or cables that are of marginal quality, and provides a medium-speed data rate.
•  2 (30a): Suitable for short cables. Provides a fast data rate.
•  3 (30a): Provides the fastest data rate but is only suitable for very short cables.
Note
The maximum achievable data rate depends on a number of factors, such as cable length, the number of junctions, and your slip ring installation. You can measure the link speed by performing the “Testing the Sonar Head telemetry” procedure.
VDSL SNR Margin
The VDSL Signal to Noise Ratio (SNR) Margin controls the amount of noise and tolerance in the cable. It is the difference between the actual SNR and the minimal SNR required to sync at a specific speed. For longer cables, use 6 dB instead of 9 dB.
IP Address, Port, Subnet Mask, and Default Gateway
These network parameters are used to identify and locate the Sonar Head on the local network. If you need to set up a unique network environment, you can change the IP Address, Port, Subnet Mask, and Default Gateway of the Sonar Head using the Head Network Setup dialog box.
Note
Your Sonar Processor must be on the same network as the Sonar Head.
