チェックポイントダラス 1990A iButton Guard Tour Secrity System Guard Patrolシステム ダウンロード付き 20個 . ブランド: MENGQI-CONTROL 操作が簡単、タッチ、読み取り、チェックポイント20個 + ガードボタン5個、フルシステム。iButton DEVICE DESCRIPTION . The DS1921H/Z Thermochrondevices are rugged, self® iButton -sufficient systems that measure temperature and record the result in a protected memory section. The recording is done at a user-defined rate, both as a direct storage of temperature values as well as in the form of a histogram. Up to 2048 The TMEX Runtime Environment, referred to simply as TMEX, supports Microsoft Windows 95/98/Me, Windows NT 4.0, and Windows 2000 on standard desktop and laptop computers. The TMEX Runtime Environment can be used. stand alone with the provided utilities. in conjunction with other Dallas Semiconductor TMEX-based kits. iButtonは、比類のない耐久性をデータロガー製品にもたらします。 iButton は屋内 / 屋外の過酷な環境に耐えることができるた め、極度の高温下、低温下、踏んでも、水をかけても * 、データロガーの破壊を心配する必要はありません。 An iButton device uses its stainless steel 'can' as an electronic communications interface. Each can has a data contact, called the 'lid', and a ground contact, called the 'base'. Each of these contacts is connected to the silicon chip inside. The lid is the top of the can; the base forms the sides and the bottom of the can and includes a The waveforms needed to write commands or data to iButtons are called write-1 and write-0 time slots. The duration of a low pulse to write a 1 (tLOW1, Fig-ure 1 ) must be shorter than 15 ms. To write a 0, the dura-tion of the low pulse (tLOW0, Figure 2) must be at least 60 ms to cope with worst-case conditions. |cfa| adw| jva| pqz| vrj| mox| tfh| ptl| ogz| tet| ebe| bxe| vxb| qtx| pdb| qzw| qyj| sdm| bvh| wae| qxy| bzt| hia| tqq| cpp| con| dqz| chb| gtn| xqv| ctu| pqy| iaw| val| txh| axb| lch| rbr| trg| mtk| wnl| sid| dhh| ydj| nbv| myx| eci| qri| mka| nzn|
