iimveliso

2.3 IPHANELI YAPHAMBILI Ulawulo kwiphaneli engaphambili lubandakanya iswitsha yaMANDLA, iqhosha lokuSETYENZISWA OKUSHA, kunye ne-MARGIN switch okanye i-jumper. Umsebenzi kunye nokusebenza KWAMANDLA kunye nolawulo lwe-RESET kuxoxwe ngalo kwenye indawo kule ncwadana. Ukutshintsha kwe-MARGIN okanye i-pin jumper luvavanyo lokubonelela ngamandla / uncedo lokuxilonga ukugcinwa kwaye kufuneka lushiywe kwindawo ye-NOM ngamaxesha onke. Iphaneli yangaphambili iqulethe izikhombisi ezibeka esweni ukusebenza kwemodyuli kwaye isebenze njengoncedo ekuhlukaniseni impazamo. Iimpawu ziquka i-diode ekhupha ukukhanya (i-LED) kunye ne-3-digital alphanumeric display. Iimpawu ze-LED kumazantsi ekhohlo kwipaneli yangaphambili zinika isibonakaliso sesimo sobonelelo lwamandla kunye nesalathisi kumbindi wasekunene wezibane zephaneli ukuba imodyuli yefeni iyasilela. Ii-LED kwiibhodi nganye zisetyenziselwa kunye nomboniso we-alphanumeric ukuhlukanisa ukungasebenzi kakuhle kwiibhodi. Ulwazi oluthe vetshe malunga nokusetyenziswa kwezalathi zemodyuli lufumaneka kwiCandelo lesi-3 lale manuwali. 2.4 IPHAneli yangasemva Iphaneli yangasemva iqulethe intambo yamandla ye-chassis yebhodi ye-I/O, ibhodi yokuqhawula i-backplane ye-100-pin, kunye ne-grounding lug. Njengoko kuboniswe kwiiThebhile 2-2 kunye ne-2-3, iibhodi ze-I / O zifakwe kwi-chassis kwi-slot ehambelana nenani kwibhodi esebenzayo efakwe phambi kwemodyuli. Lonke unxibelelwano kunye ne-LCN okanye i-Data Hiway ihamba ngeebhodi ze-I / O. Iintambo ze-coaxial ezihamba kwiibhodi zidibaniswe yi-tee connector kunye necala lokuphuma kwe-tee ukuya kwibhodi elandelayo (okanye kumthwalo wokuphelisa kwi-tee yokugqibela kuthotho). Izixhumi ze-coax zebhodi ye-I / O ziphawulwe A kunye no-B; qinisekisa ukuba intambo engu-A iqhagamshela kwisidibanisi esingu-A nokuba intambo engu-B iqhagamshelwe kwisidibanisi esingu-B. Iintambo zeRibhoni zisetyenziselwa ukudibanisa kwizinto ezifana nemodyuli ye-Winchester drive. Ezinye izihlanganisi, umzekelo i-RS-232C okanye i-RS-449 kwi-Computer Gateway, nazo zisetyenziswa. 2.5 ULUNGISO LWENDAWO Akukho luhlenga-hlengiso lwangaphandle kwimodyuli. Ibhodi ye-LCN I / O (CLCN A/B ye-CE Compliant) ibhodi, nangona kunjalo, inedilesi yemodyuli ye-jumper pack ekufuneka ibonakaliswe kwidilesi ethile ye-node ehlala kuyo kwi-LCN. Jonga kwicandelwana 8.1 le-LCN System Installation Manual ukwenzela ukupinwa kwenkqubo. 2.6 I-EPDGP I/O BOARD PINNING Ibhodi ye-EPDGP I/O, ukuba ikhona, ineenketho zokukhonkxa zokuseta umthunzi ongasemva ongagqibekanga weCRT ukuba i-palette ayimiselwanga kwi-schematic (I-Palette yokuSeta ngumyalelo omtsha kwi-Release 320). Unokufumana ulwazi olongezelelweyo kumyalelo we-Set Palette kwi-Picture Editor Reference Manual kwi-Mimplementation/Engineering Operations - 2 binder. I-EPDGP ikwanokhetho loqwalaselo olusetelwe nokuba yi-Keyboard yeNjineli okanye i-Keyboard yoMphathi. (Ukuba zombini ii-keyboards zifakiwe, i-EPDGP imiselwe i-Keyboard yoMphathi, kwaye i-Keyboard yeNjineli idityaniswe kwi-Keyboard yoMphathi.) Umzobo 2-6 ubonisa ikhibhodi kunye neenketho zangasemva zeCRT ze-EPDGP I/O.
