In this paper, three Sen brand P3301 remote control system, for example, talk about the keyboard conversion skills. P3301 through the interface XS06 keyboard and the system microprocessor connected, XS06 has eight port lines, numbered 1 to 8, different two port ask different key functions, according to the system installation guide given the connection shown in Figure 1 As shown (8 preselection keys).
