(riješeno) LPT raspored pinova na ploči: gigabyte -> standardni

[Pupo]

Treba mi LPT port, a ploča(Gigabyte EP45-DS3) ga nema na I/O panelu već mi je potreban bracket i odem ja u trgovinu i kupim standardni bracket. Ali nula bodova, il ovaj moj što sam kupio nije standardni, il na matičnoj nije standardni raspored. Pa ako netko ima iskustva da mi pomogne s gigabyte rasporedom, odnosno s isčitavanjem njihovih skraćenica tako da si mogu sam složit raspored na bracketu.





Ovo je kao standardni bracket, bar bi trebao biti



i nemogu ga uštekat na ploču zbog ovog dummy pina, al to bi rješio, bitno da složim raspored kako treba


Uspio sam dio "dešifrirat" ali ostalo je još par koje nisam uspio prokužit

1. STB- = 1 Strobe
2. AFD- = 14 Autofeed
4. ERR- = 15 Error

Evo i u slici:

Namjerno sam "stavio" samo jednu masu (GND), sad kad vidiš logiku lako i ostale dodaš.
Za lakše razumjevanje kratica vidi ECP_Parallel, a evo C/P "rješenja":

Gigabyte motherboards that have the LPT header have an unusual pinout. (Gigabyte provides the pinout on their website and in their user manuals.) The header is in a 2x13 configuration, which seems to be what is used on all motherboards that have LPT headers. Unfortunately, pin 24 rather than pin 26 in not connected, which is what makes Gigabyte LPT headers different. Pin 26 is connected to ground, but usually pin 24 would be connected to ground.

The DB-25 end of the LPT cable has 25 pins. Pins 18 - 25 should be connected to ground. If a straight ribbon cable is used to connect the LPT header (pins 1 - 25) to the DB-25 connector, then Gigabyte motherboards will leave DB-25 pin 25 unconnected (DB-25 pin 25 connects to LPT header pin 24).

Generic LPT port cables are available, and inexpensive. They use straight ribbon cables. They connect LPT header pins 1 - 25 to DB-25 connector pins 1 - 25 (but the pins are numbered differently).

Gigabyte has a LPT cable, part number 12CF1-1LP001-01R, but it is in fact just an overpriced generic cable. It uses a straight ribbon cable that does not compensate for the LPT header pin 24 vs. pin 26 issue.

If a circuit on a device connected to the DB-25 connector (via the Gigabyte LPT header and a generic cable) uses pin 25 for its ground connection alone, it will probably fail. If it ties at least one of the other DB-25 ground pins 18 - 24 to pin 25 (or doesn't use pin 25 at all) then it will probably work.

The Gigabyte LPT cable is not sold at many places, and they are overpriced and identical to the generic cables, which are cheaper and sold more places.

If you need a correct DB-25 LPT port from a Gigabyte motherboard, you could take a generic LPT cable, remove the ribbon cable from the IDC connector, split the ribbon between wires 23 and 24, twist wires 24 and 25 180 degrees, and reinsert the ribbon cable into the IDC connector: wires 1 - 23 where they were before and wire 25 where it was before, but put wire 24 at the end (where the 26th wire of a 26 wire ribbon cable would go), leaving a gap where wire 24 was.

Hvala dečki, uspio sam riješit. Dummy pin sam probušio s malim borerom, a drugi sam zaljepio, a žice sam odrezao i polemio nanovo s drugačijim rasporedom. I malo sam dotjerao kabal.

ja sam to sam napravio, kupio u electronic centru 2x13 pin konektor, i uzeo stari kabel harda, ženski 25 pinski i polemio to sve skupa, šljaka bez problema, samo treba pratiti pinove u manualu od ploče
