The size of the common memory is 4096 words. When a station becomes the data sender station, it sends data of prespecified area of the common memory. All other stations receive the data, and store them into their common memory. Therefore, the common memory in The common memory is allocated to the Link register (W) in the T2N/T3H. The size o
