Communications interface for the PDP-11 and the Nuclear Data 6600
A communications interface has been designed to send data from the Nuclear Data 6600(ND6600), a computer-based multichannel analyzer, to a PDP-11/34, operating under RSX-11M. The hardware consists of a Nuclear Data Serial Communications Processor (SCP) and a CAMAC Kinetics Systems 3340 communications interface. On the PDP-11, Digital Data Communications Message Protocol (DDCMP) software was written to check and reply to each data buffer. The PDP-11 code also saves the data on disk and interfaces with existing communications software. On the Nuclear Data, the DDCMP is contained in firmware on the SCP board. Software was written to retrieve data from disk and to interface with the system software that accesses the SCP board.
