excluding the 30 m (99 ft.) of masthead cable.
2. It is not necessary to connect all autopilot control units to
SimNet for data sharing. However, if you want to have full
redundancy and SimNet control, e.g. select sources, you
have to connect the actual unit to SimNet.

Instrument system. IS15 makes no load on SimNet.
