LKV-HDMI input settings

[KA5BBC]

Where can I alter the IP settings in the Portsdown build so that I can switch the LKV373a from multicast to unicast?
In multicast mode the device is causing network issues for me.
I know that the change at the Portsdown end needs to be from udp://@239.255.42.42:5004 to udp://@:5004 and that I have to send the following line to the LKV373a to setup unicast - curl "http://'lkvipaddress'/dev/info.cgi?action=streaminfo&udp=n&rtp=y&multicast=n&unicast=y&mcadtaddr='portsdownipaddress'&port=5004"

My thanks in advance for any help
