The ngdp framework advanced topics are described. Namely we consider work with CAMAC hardware, "selfflow" nodes for the data acquisition systems with the As-Soon-As-Possible policy, ng_mm(4) as alternative to ng_socket(4), the control subsystem, user context utilities, events representation for the ROOT package, test and debug nodes, possible advancements for netgraph(4), etc. It is shown that the { \itshape ngdp} is suitable for building lightweight DAQ systems to handle CAMAC. The investigation has been performed at the Veksler and Baldin Laboratory of High Energy Physics, JINR.
