2.3 FRONT PANEL Zowongolera pagawo lakutsogolo la magetsi zimakhala ndi chosinthira POWER, batani la RESET, FAN CONTROL, ndi LO-NOM-HI margin jumper. Ntchito ndi machitidwe a mphamvu ndi kukonzanso zowongolera zikukambidwa kwina mu bukhuli. Mtsinje wothamanga ndi kuyesa kwa magetsi / chithandizo chothandizira matenda ndipo chiyenera kusiyidwa mu NOM (pakati) jumper malo nthawi zonse. Mphamvu yamagetsi ya EC imakhala ndi chosinthira chowongolera / chodumphira ndipo imayikidwa ngati mphamvu yoyendetsedwa ndi kutentha kapena yokhazikika (onani Chithunzi 3-2). Kuyika kumodzi kumasinthasintha mphamvu ya fan ndi kutentha ndi katundu. Kuyika kwina kumapereka 27 volts mosalekeza. Gulu lakutsogolo lili ndi zizindikiro zomwe zimapereka mawonekedwe a magwiridwe antchito ndikuthandizira kudzipatula. Zizindikiro za LED kumanzere kumanzere kwa gulu lakutsogolo (magetsi) zimapereka chizindikiritso cha momwe magetsi alili. Chizindikiro china pamagetsi opangira ma fan ngati msonkhano wa fan ukulephera. Ma LED pa bolodi lililonse amagwiritsidwa ntchito limodzi ndi chiwonetsero cha zilembo za alphanumeric pa bolodi la purosesa kuti alekanitse zolakwika pama board. Zambiri pakugwiritsa ntchito zizindikiro za gawoli zili mu Gawo 3 la bukhuli. 2.4 KUM'MBUYO Kumbuyo kwake kumakhala ma board a I/O (paddleboards), chingwe chamagetsi cha chassis, bolodi lopumira la mapini 100 (ngati liperekedwa), ndi choyikapo pansi. Monga momwe tawonetsera mu Table 2-1 matabwa a I / O amaikidwa mu chassis mu kagawo kolingana ndi chiwerengero cha bolodi lomwe likugwiritsidwa ntchito lomwe limayikidwa kutsogolo kwa gawoli. Kulankhulana konse ndi Micro TDC 3000 kumadutsa pama board a I/O. Pali njira ziwiri zoyankhulirana pakati pa node pa dongosolo. Ma paddleboards wamba a LCNI I/O amapanga Local Control Network yokhala ndi zingwe zama coaxial zomwe zimayendera ma node onse a LCN mu netiweki. Mu netiweki, matabwa onse a LCN I/O amalumikizidwa ndi zolumikizira za T ndi chingwe (kapena kutsitsa katundu pa T womaliza pamndandanda). Chifukwa cha kutsitsa, kutalika kwa chingwe cha LCN ndi 2 mita (mamita 6), kotero pakhoza kuwoneka ngati "zinyalala" za chingwe pamene matabwa a LCN apafupi alumikizidwa. Mu ma LCN cabling onse, zolumikizira bolodi za I/O zimalembedwa A ndi B; onetsetsani kuti chingwe A chikugwirizana ndi cholumikizira A ndi kuti chingwe B chikugwirizana ndi B cholumikizira. Netiweki yapamtunda yayifupi ya LCN yapangidwa yomwe imagwiritsa ntchito ma waya opindika ndi ma multinode module backplane m'malo mwa chingwe cha coaxial ndi zolumikizira T. Zopalasa za I/O zomwe zimagwiritsidwa ntchito pa netiweki iyi ndi ma board a TP485. Ma LCN awiri opotoka awa amatsata mawonekedwe a RS 485. Imodzi mwama board a purosesa a K2LCN ndi makadi a TP485 I/O mu slot 9 ya nsanja iliyonse imapereka wotchi kumanode ena pamaneti amfupi. Zingwe ziwiri zopotoka zomwe zimamangiriza LCN yaufupi iyi palimodzi zimakiyidwa kuti zingwe A ndi B zisalumikizidwe molakwika ndikuyimitsa katundu kumangidwira. Zingwe za riboni zimagwiritsidwa ntchito polumikizana ndi zinthu monga Winchester Drive, Cartridge Drive, ndi zotumphukira zina. Zolumikizira zina, mwachitsanzo RS 232C kapena RS 449 pa Computer Gateway, zimagwiritsidwanso ntchito.
