Class VectorPacketParser

All Implemented Interfaces:

java.io.Serializable

public class VectorPacketParser
extends PacketParser

Parses SIAM data packets for Nortek Vector ADV. The Vector is a streaming instrument that sends System data packets at 1 Hz and Velocity data packets at another (higher) rate (2-64 Hz). The System data packets contain a velocity multiplier that is used to scale the velocity readings, so they provide context for the velocity data packets. To accommodate this, the VectorPacketParser (this class) takes both kinds of packets, and uses the system data packets to set its internal copy of the velocity multilplier. It may also be initialized with a multiplier value, or it may be set using setMult(). When a VectorPacketParser is obtained via Vector.getParser(), the latest value of velocity multiplier is passed to the VectorPacketParser by the Vector instrument service. The typical use pattern is to get a single VectorPacketParser and feed it a stream of packets as they come in, thus ensuring that the correct multiplier is set when a velocity data packet arrives.
