Bbefore we begin beforehand we study explanation and use lan. lan a connection local that make possible us use collectiv sebagaian or entire wares computer in area.
utp, abbreviation from “unshielded twisted pair" . called unshielded because less hold back towards interferensi electromagnetic. and called twisted pair the exercise in it found cable pair that composed spiral alias mutual berlilitan. there 5 cable categories utp. from category 1 until category 5. for famous computer network category 3 and category 5.
category 3 can for data transmission until 10 mbps, category 5 until 100 mbps. well klo only make example makes computer network at office ato campus ato warnet, most ngirit yes pake category 3. udah more than enough.
setau i am there many brands that go around at market, only stubborn famous and cheap relative brand belden - made in usa. per the meter revolves from rp. 1500 - 2000, - if want to fall cheap and pake many buy aja one box, length around 150meteran. don't forget to buy konektor. konektor tuh its for like colo only bigger telephone. say aja mo buy konektor rj-45. the price klo ngecer around rp. 2500, - denunciated
photo rj45 - konektor for cable utp
photo rj - 45 that still new, not yet at gencet pake pliers
crimp tool one again of vital importance, you kudu has special pliers makes masang konektor to cable utp, the impressive term “crimp tool" . this is tool the to it make ‘ngematiin’ ato ‘nanem’ ato what that the term konektor to cable utp. so once udah at ‘tang’ udah ga can be removed again that konektor. the price really rather expensive membanding pliers usually. deliver rp. 75rb - 150rb. and klo mo more ok, let ga nanggung add money again around 125rban make to buy lan tester. buy it brand from taiwan aja. cheaper. its for tuh like box, and there lamp led 8 pair, can watertight wink.
ok now device udah ready, i begin aja. in general cable installing utp there 2 types, type straight and type cross. called type straight the exercise masing masing cable the total 8 that berkorespondensi 1, direct. while called cross the exercise there crossing in the cable composition. confused?
ok! for type straight that used to make nyambungin from client to hub. while for type cross to client direct to client (cpu to cpu) ato from hub to hub.
we study formerly type straight
sequence pin type straighttipe this easiest is made. why? the correspondence direct the exercise 1. standard sequence it sih like this (seen from bolongan konektor, from left to right - see photo beside)s: 2 orange - 1 ijo - 2 blue - 1 ijo - 2 brown. 2 orange here pair the purpose orange young same orange old, and so on. but ga take care to come along standard that coloration also actually not problem. important sequence the cable. end example here sequence pin the first orange young, so other end sequence ping the first also must orange young. so to deliver end mutual nyambung. actually not all pin used. important pin number 1,2,3 and 6. so example that banded only pin 1,2,3 and 6 while pin other is not installed, doesn't so exercise. make detail try to see photo under, i am photo from a book (tries to quess! can ga, what hayuooo book? : d)
straight tru and cross pin
left sequence correspondence makes type straigh, right cross
well time mo pair you truncate the cable, trus compile the cable trus ratain pake piso cut exist in crimp tool. you ga necessary busy busy must ngelepasin isolation in cable end part, your time the exercise is masukin that is cable to konektor trus at gencet pake crimp tool, actually moment that is pin exist in konektor nembus mpe dalem cable. look at, so that gencet hard. the exercise klo ga hard sometimes that is pin ga penetrated into the cable isolation. kalo udah trus you are test pake lan tester. masukin cable end end to the tool, trus nyalain, klo lamp led at lan tester flame all, from number 1 mpe 8 mean you are successful. klo there one other ga flame means possibility in pin number there problem. easiest manner that is you gencet again pake pliers. possibility pin not yet penetrated. kalo udah you gencet kok still ga nyambung, try to investigate the correspondence delivers pin udah 1 blon. klo obvious udah bener and still to fail, is meaning really you today unlucky. . kesian deh. . hehe. . come again aja. . okay!
lan tester
lan tester - tool makes ngecek the cable nyambung bener ato ga. for type straight klo bener ntar from led 1 mpe 8 blink.
next photo from under from cable end utp udah mempasangi konektor and success well (sequence coloration pin come along standard):
example konektor rj45 udah installed at cable utp and success well
sequence pin standard
and klo this is ga standard, try perhatiin sequence colour pinnya… ga standard so. but tetep aja can, important the correspondence one one (special type straight):
example konektor rj45 udah installed at cable utp and success well - not standard
sequence pin not standard
now type cross
for type cross that is mempake make nyabungin direct deliver 2 pc, ato usually make nyambungin deliver hub. (example because colo at hub less). manner pair it also actually easy. same like type straight, pin mempake also actually only 4 pin aja, pin 1-2-3 and 6. well difference fit pair it. klo at type cross, pin 1 nyambung to pin 3 other ends. pin 2 to 6, pin 3 to 1 and pin 6 to 2. detail try deh tough “gambar 5? . the practise gini, at your first end compiles pin appropriate standard make type “straight” well at end laen you compile pin appropriate standard make type “cross" .
still confused? gini deh the easy:
first end:
1: orange young
2: orange old
3: ijo young
4: light blue
5: dark blue
6: ijo old
7: butbrown
8: deep brown
so mengujung other must like this:
1: ijo young
2: ijo old
3: orange young
4: light blue
5: dark blue
6: orange old
7: butbrown
8: deep brown
rather ngerti kan? so here number position 1,2,3 ma 6 menuker. . well ntar klo fit at test pake lan tester ntar led 1,2,3, ma 6 mutual swop. klo type straight kan the flame sequence, well klo type cross there that jump to jump. but definitive kudu flame all every led from number 1 mpe 8.
ok deh congratulation make network. good you can success time pair konektor at the cable. . hehe. . moga this science is useful makes you, my in the former fume the exercise is first makes funny network so deh, make ngupas my the cable stills pake cutter, while kan udah there tuh at crimp tool. udah gitu the end end every my cable peels of again pake cutter. while right ga take care at peel atu atu, let it be aja flat, the exercise ntar fit at ‘crimp tool’ kan that is pin masing masing penetrated to dalem the cable. . stupid deh formerly. . moga you ga do matter same like formerly
