As far as the PAT01, that is the transceiver I bought in the 1980's! The only difference I see is the switch which allows it to be module 1 or module 9... I've even seen the TM751 described as "long range"
Mike - Vanguard will use the CM19A and the TM751 if you don't have the CM15A. They often sell it as a package without the CM15A.
The reason all the pictures are the same is that the cameras are not switching.
Make sure the TM751 is plugged in and on the same house code as the cameras. Make sure the Vanguard software settings are correct. You can't use a surge supressor strip on the TM751 or cameras. There may be line noise interfering with the signal going from the TM751 to the cameras. That's always a possibility. They could be on opposite phases of the electrical system.
Try to eliminate the variables. As Mike suggested, get them working close together (even the same outlet) first, then set them up where they will be. You can try switching them with a palmpad remote as an intermediate step as well.
Admittedly, I haven't used Vanguard software, but, if set correctly, it will work.
Good Luck!
