| Abstract: | To expand the usage life of import equipment and obtain optimal economic efficiency,a new type of plotting apparatus is badly needed to reconstruct CRT plotter used in DDL-III system. Based on the characters of IEEE-4888 bus bar and GPIB interface,data collection and collection format in DDL-III system are analyzed,software and hardware design for reconstructing the intelligent interface card used in CRT plotter with Printrex 820 plotting apparatus is described. |
