3.4. DIS
When the Target is configured for DIS operation it can be connected directly to the DIS network.
Distributed Interactive Simulation (DIS) is a simulation protocol standard developed jointly by
industry and the military to enable interoperation of simulation and training devices over local
and wide area networks.
One of the more difficult and often underestimated aspects of simulation over local and wide area
networks is achieving a realistic radio communication environment. With the DIS option active,
the local radio and intercom modeling performed by the Target software is extended over the local
and wide area network. Communication simulation between multiple DIS compatible network
devices is invisible to the user with full radio modeling across systems. All recent released ver-
sions of the DIS standard are supported and are available to the user for selection.
During DIS operation, the Target transmits and receives DIS standard PDUs. Since the Target is
involved strictly with communications simulation it is only concerned with Transmitter, Signal
and Receiver PDUs.
The exception to this is Entity State PDUs which are received to accommodate entity attach fea-
tures whereby a radio modeled on the Target is attached to an entity on the network.
