Hi,
I am really breaking my head what could be the problem here?
This used to work:
VTH1510 -> 2 pair ethernet -> inline-coupler -> 3 pair ethernet cable to downstairs -> some multiport generic switch -> VTO1210C-X
For some reason today ip works, DHCP works, but when I try to connect to the VTO I get a black screen for about 20 seconds and a message device offline.
When I replace the inline coupler with a passive ethernet switch (nothing else connected just these two cables) everything works again.
I replace the switch with the coupler, all works (incoming calls and even door open button) but video does not.
I have tried changing couplers and well, this used to work, I have no idea what could have gone wrong, not even what else to try?
Ideas?
Alex
