My work is planning on replacing their old dispatch consoles with MCC5500. Since the new system replaces the old DIU's, my question is where in the new system do the secure keys get installed? I've browsed through the MCC5500 installation manual and didn't see it anywhere. The only mention of encryption is the users guide, how to go clear to coded.
Thanks

It would be loaded in the control station radios as the MCC5500 is not a wireleine console.

The Motorola salesman says we don't need a DIU with the MCC5500. We're using quantars for the 3 main channels, the rest will be consolettes . I'm sure the quantars don't store keys.. Maybe the DAP module would, but I didn't see any mention of it in the installation manual. I'm just making sure we get what we need the system to do and the salesman is correct..
Thanks

I guess my question is why use Quantars? They seem like really expensive base radios unless they are also being utilized as the system repeaters and the console is wirelined into them.
If this is the case then a DUI should be required as there is no way for the Quantar to decode any digital or encryption.

You should ask for a block diagram from engineering to see how they propose to do what you need to do.

Yes, the quantars are repeaters and are off site. The whole system is eventually going to be replaced, but budgets aren't allowing it to be done all at once. I will have to get clarification from Motorola.
Thanks again

The DIU's are still definitely required for encryption, if still using Quantars via wireline. As the other poster stated, the consolettes would be keyloaded, if they are being used.
