SetPacketId Method (position, type)

Sets the position, and the type, of the packet ID.

Parameters

position (Int32): Position where packet ID is located, counted from the first byte of the header data.

type (VariantType): Type of packet ID.

Remarks

PacketId is an automatically increasing packet counter. It increases every time, when a new GXPacket is sent. Use PacketId to set the location, and the type, of the packet ID, to the GXPacket. When the maximum value is reached, PacketId is automatically reset to 1. By default packet ID is not used. A media must be selected, before using this method.
