Once the plotter has received the informa- tion from the OLDS unit, it will rapidly draw lines on the chart roll with a series of move- ments. The paper roll will move inch per step, while the pen will move only from side to side or up and down. The CALCOMP digital plotter consists of a drum type plotter and an electronic controller (OLDS logic unit) mounted on a single bedplate. (See fig. 9-6.) Data Systems Technicians (DS) and/or civilian technicians are normally assigned to NEDN activ- ities 6olely to maintain the computers and as- sociated equipment. It is not, and should not be, OLDS IS CONTAINED IN BACK PORTION OF PLOTTER PEN ASSEMBLY (SOLENOID). DIGITAL PLOTTER RECEIVES COMPUTER GENERATED DATA VIA TELCO LINES THROUGH SUBSETS AND DRAWS CONTOURS AND PRINTS SYMBOLS ON PREPRINTED CHARTS Figure 9-6. —NEDN On-Line (OLDS). Display System the function of the Aerographer's Mate to carry out maintenance on this type equipment. NAVAL ENVIRONMENTAL DISPLAY STATION (NEDS) The NEDS is a transmission, storage, dis- play and printout unit. It consists of a mini computer with storage capability, a television monitor display, a high speed teletype printer and a hard copy plotter. It will replace pre- vious Automatic Data Processing equipment at NEDN activities and will eventually replace facsimile equipment at other Naval Weather Service Activities. A NEDS system is being developed for shipboard use. FLENUMWEACEN Monterey transmits data from its computers to the storage unit at NEDS. The operator then may display any of the data at any t
