Control via TCP/IP LAN Remote Control Port
Connect to the LAN port.
Users can connect directly to the LAN port with a changeover cable or via a switch or router with
normal Ethernet cables.
Users can also connect via a local area network.
The TCP/IP address of the Fovea can be obtained from a DHCP server or set manually in
Menu>Miscellaneous>Networking
[IP Address Type Use Static]
Static IP Address 169.254.0.3
Default Gateway IP Ad192.168.254.250
Subnet Mask 255.255.255.0 ↓
If the user changes from DHCP to Static or from Static to DHCP it is recommended to re-boot the
processor to ensure the new state is acknowledged fully.
Note:- port number is 30001
Examples of code
The code structure is the same as in the RS232 examples given in the previous section of this guide.
Send an identify request string to see if the user can talk to the box. Send 16x A, i.e.
AAAAAAAAAAAAAAAA. If successful communication is established the answer VXL500HD is
returned.
The answer is in the form of a much longer string than for RS232, as described in the API manual – it
looks like this:-

Understanding the range of data of the ‘Value’
The value ranges are not listed for each function, instead the user can send a request for the
maximum and minimum valid values thereby establishing the operating range of the value segment
of the command string.
An ON/OFF command will only have two valid values
A setting such as audio delay will have a wide range of valid range settings.
Requesting the available range of the ‘Value’
This example is used to provide easily visible changes:-
