Hi Sophos User1175 , 
 Thanks for reaching out to the Sophos Community Forum. 
 To point an offline device to a specific Update Cache server, you will need to install using the command line. If the installation is already completed, you can instead append the "--registeronly" switch as shown below. 
 - SophosSetup.exe --messagerelays=x.x.x.x --registeronly 
 You can find more information on this in the following article. - Installer command-line options for Windows 
 If these devices are not internet-facing, I'd suggest ensuring you have the "Message Relay" component deployed to your Update Cache as well, but it sounds like this is already the case.
