Thanks for the quick reply Johnny. I think I was not clear in my question as the TZT version is one which I could interpret as being 5.01. It also looks like the DFF1-UHD is 1.03 while the DFF3 looks like 1.05. I don't know what version the DRS12A has. Thanks for the ID of the instance problem, I will talk with my installer to correct. My question is basically to insure I update to latest version on all equipment.
Thanks.
