To get the fill benefit of a smartlink, what enhancements does a PC need?
As I understand it the PC needs:
A gun with a Smartlink (built in or underbarrel)
A commlink
One of the following - Cyberglasses, cybergoggles, cybercontacts, cybereyes with smartlink as one of the options, or a datajack.
They need to run the smartlink and other devices through the commlink in order to get any bonus to dice pool.
Using the smartlink gives you +2 to accuracy. Glasses, goggles or contacts give you +1 to dice pool, cybereyes or datajack gives you +2 dice.
You can skip the commlink if you run a wire from your gun to your datajack or glasses/goggles.
Right?
