Is a tower with FM and the cables is hard to get 1Gb negotiation. With Cat8 cables is no problem with the POE on the device, but If I POE with the cnPulse the cable link at 100Mb. If I use the aux port for sync is working a 1Gb.
I now using the standar conection for the cnPulse
It's possible the get sync in both 450m from the AUX port?
Using a single cnPulse, you would not be able to provide AUX sync to two 450m devices at the same time, unfortunately. However, if you are able to acquire a standard UGPS module, it supports dual AUX sync outputs, but does not support PoE or CambiumSYNC. It sounds like that solution would work for you.
Please note, when using a standard UGPS, you should provide auxilliary power on the center connector when using it with two 450i or 450m devices. You should also enable UGPS power on both devices to be able to look at GPS data on the sync page.
Hope this helps.
