Wannan mai jujjuyawar mu'amala ya dogara ne akan FPGA, yana ba da ƙirar E1 guda ɗaya da siriyal na RS485 guda ɗaya, watsa 1Channel RS485 ta hanyar E1 interface. Samfurin yana karya ta hanyar saɓani tsakanin nisa ta hanyar mu'amala ta al'ada da ƙimar sadarwa, baya ga haka, yana iya magance tsangwama na lantarki, tsoma bakin ƙasa da lalacewar walƙiya. Na'urar tana haɓaka aminci sosai, tsaro da sirrin sadarwar bayanai. Ana amfani dashi ko'ina don sarrafa masana'antu daban-daban, sarrafa tsari da lokutan sarrafa zirga-zirga, musamman don Bankin, da Power da sauran sassa da tsarin waɗanda ke da buƙatu na musamman na yanayin kutse na lantarki. Adadin sadarwar keɓancewa ta hanyar sadarwa ya kai 921.6KBPS.
