Hi LP 600-1048-xt-lte-vz .... really they are the same thing, they are both cell only (verizon lte) comms for interlogix simon panels the xt-511 are made by ADC .... the 600-1048 are made by interlogix for awhile, we thought the xt-511-us-vz/at were dual-path, but we found out that was incorrect so really there is no difference, just different manufacturer skus hope that helps
What is the difference between the 511 Verizon lte communicator and the other Verizon lte one? The 1048 one?
