First, what does a smartgun link do for a character? According to the rules,
it makes it easier for him to make a shot (makes a everyday difficulty into
a trivial difficulty). It also gives the user a bunch of trivial information
about the status of the gun (not actually in the rules, but in a lot of the
fluff). Third, it allows ejection of clips for a free action. The Smartgun
Link level II adds the ability to utilize a rangefinder for longer-range
shots, a "more alert, intelligent-feeling" weapon, and the ability to
calculate arcs for indirectly-fired weapons, and a reduced difficulty for
Given this information, and my mild Firearms background skill :) I think
that a smartgun link includes the following bits:
A gun, which has either been internally modified, or has an external
adapter. If it has an external adapter, some functions may not be available,
or are more limited. At any rate, it has (at a minimum) a set of kinesthetic
sensors to determine where the gun is pointing, a way of determining the
ballistic characteristics of the ammunition loaded (most likely by reading a
"barcode" on the round as/before it is chambered), and a method of passing
this information on.
A datajack of some kind. The typical one in SR of 2050 or later is a
dedicated induction datajack sited in the user's palm.
A dedicated display link.
A set of kinesthetic sensors to determine where the user's field of vision
A dedicated (and probably pretty dumb) ballistic computer.
Link running between all this.
This is the way it all works together:
The gun passes the ballistic numbers through the users datajack to the
ballistic computer, along with the rest of the guntrivia. The ballistic
computer crunches the numbers, and comes up with a predicted ballistic
track. This calculation requires nothing more than a Physics 101 knowledge
of the world, and knowledge of the initial energy of the round and its
aerodynamic performance. This is then passed on to the display link, along
with the rest of the guntrivia. The display link renders the ballistic arc
in the user's field of vision as a line passing through any objects in the
way. This system relies on the user to be able to pick up on other cues to
determine whether or not the arc passes before, behind or through a target
(such as the user's own depth perception mechanisms).
If the smartgun and the user both conform to ADVAT.328 (the smartgun II
protocol), certain other functions are also available. If a rangefinder is
present, the ballistic computer/display link can change the appearance of
the arc in the user's field of vision to indicate when it passes through a
target, making shots beyond the effective binocular range of the user
easier(about 20 feet IIRC. Beyond that, the human eye is in an infinite
focus mode...). Furthermore, the ballistic computer has additional capacity,
allowing it to calculate high-arc, low initial velocity, tracks (such as
that from a grenade launcher firing indirectly). The connection between the
gun and the system is higher bandwidth, giving a sharper feel to the
information. Possibly the user can input wind information to the computer
via DNI to allow it to calculate windage.
