How can I use control device (matrix action) on a non slaved drone?
By using a commlink, cyberdeck/cyberjack combination, RCC or a Living Persona.
Or how does the tarpit action Work against an Enemy drone? (If it isnt slaved).
Similar to a Data Spike.
I can see a PAN gives firewall to its slaved devices, but nothing about DP.
It doesn't only apply to firewall.
For example, if there is a cyberdeck in the network and you turned your cyberdeck to silent running and your drone is connected to the cyberdeck then the drone will be inside the silent running network. To spot the drone (or rather your entire silent running PAN) an observer need to beat your willpower and the sleaze rating of your cyberdeck.
