2.3 FRONT PANEL Ulamuliro wakutsogolo umakhala ndi chosinthira POWER, batani la RESET, ndi MARGIN switch kapena jumper. Ntchito ndi kagwiritsidwe ntchito kaulamuliro wa MPHAMVU ndi RESET zikukambidwa kwina mu bukhuli. Kusintha kwa MARGIN kapena pin jumper ndi kuyesa kwamagetsi / chithandizo chothandizira kufufuza ndipo chiyenera kusiyidwa pamalo a NOM nthawi zonse. Gulu lakutsogolo lili ndi zizindikiro zomwe zimayang'anira magwiridwe antchito a module ndikukhala ngati chithandizo pakudzipatula kolakwika. Zizindikirozi zimakhala ndi ma diode otulutsa kuwala (LED) ndi mawonedwe a zilembo za manambala atatu. Zizindikiro za LED kumunsi kumanzere kwa gulu lakutsogolo zimapereka chisonyezero cha momwe magetsi alili ndi chizindikiro pakatikati pakatikati pa magetsi ngati gawo la fan likulephera. Ma LED pa matabwa aliwonse amagwiritsidwa ntchito limodzi ndi mawonedwe a alphanumeric kuti adzilekanitse zolakwika pamatabwa. Zambiri pakugwiritsa ntchito zizindikiro za gawoli zili mu Gawo 3 la bukhuli. 2.4 PANEL YAKUM'mbuyo Mbali yakumbuyo ili ndi chingwe chamagetsi cha I/O board, 100-pin backplane breakout board, ndi choyikapo pansi. Monga momwe tawonetsera mu Matebulo 2-2 ndi 2-3, matabwa a I / O amaikidwa mu chassis mu kagawo kolingana ndi chiwerengero cha bolodi yogwiritsidwa ntchito yomwe imayikidwa kutsogolo kwa gawoli. Kulankhulana konse ndi LCN kapena Data Hiway kumadutsa pama board a I/O. Zingwe za coaxial zomwe zimathamangira ku matabwa zimalumikizidwa ndi cholumikizira cha tee ndi mbali yotuluka ya tee kupita ku bolodi lotsatira (kapena kutsitsa katundu pa tee yomaliza pamndandanda). Ma I/O board coax zolumikizira amalembedwa A ndi B; onetsetsani kuti chingwe A chikugwirizana ndi cholumikizira A ndi kuti chingwe B chikugwirizana ndi B cholumikizira. Zingwe za riboni zimagwiritsidwa ntchito polumikizana ndi zinthu monga gawo la Winchester drive. Zolumikizira zina, mwachitsanzo RS-232C kapena RS-449 pa Computer Gateway, zimagwiritsidwanso ntchito. 2.5 KUSINTHA KWA FIELD Palibe kusintha kwa magawo a gawoli. Bolodi ya LCN I/O (CLCN A/B ya CE Compliant), komabe, ili ndi ma module adilesi yodumphira yomwe imayenera kudziwika pa adilesi yomwe imakhala pa LCN. Onani ndime 8.1 ya LCN System Installation Manual polemba makina. 2.6 EPDGP I/O BOARD PINNING Bolodi ya EPDGP I/O, ngati ilipo, ili ndi zosankha zokhomera kuti zikhazikitse mthunzi wosasinthika wakumbuyo kwa CRT ngati phale silinakhazikitsidwe mwadongosolo (Set Palette ndi lamulo latsopano mu Release 320). Mungapeze zambiri pa lamulo la Set Palette mu Buku Lofotokozera la Mkonzi wa Zithunzi mu Implementation/Engineering Operations - 2 binder. EPDGP ilinso ndi njira yosinthira yomwe imayikidwa pa Kiyibodi ya Engineer kapena Keyboard ya Supervisor. (Ngati makiyibodi onse aikidwa, EPDGP imakhazikitsidwa pa Kiyibodi ya Woyang'anira, ndipo Kiyibodi ya Engineer imalumikizidwa ku Kiyibodi ya Woyang'anira.) Chithunzi 2-6 chikuwonetsa zosankha zakumbuyo za kiyibodi ndi CRT za EPDGP I/O.
