I have been working on my LT150 and need the Din 8 connector for serial control. The connector is not an 8 pin midi, which is all I can find. Does anyone know of a source for this unusal connector?


Thanks!

The connector is the same that older Macintosh computers used for serial connections to modems and printers.


You can still find these cables pretty cheap including ones that go from the macintosh serial port to a DB-9.

Thanks Andrew. Would you happen to know an online source?

Have you TRIED one of the Mac serial cables in this application (PC->LT-150)? When I built mine, it sticks in my head that the Mac pinout was different from the NEC. I could have read the wiring diagram wrong, though.


If you want to build one, I used:


From www.digikey.com -

8-pin mini-din; part # CP-2080-ND

db9-rj11 converter; part # 46-0001-ND


Take a 4-wire phone cord (8-wire stranded cat 5 cable also works but you need to put on an JR-11 4-8 connector on one end) and press one end into the converter. Remove the RJ-11 connector from the other end and solder three wires to the 8-pin din.

Actually, on further looking at the LT-150, the cable won't work out of the box. What I would recommend is buying a DIN-8 to DIN-8 cable, cutting it in half and putting a DB-9 on the cut end wired according to the LT-150 manual.


You can buy these cables at all online vendors that support Mac.

That is a GREAT idea! The din-8 soldering was a real pain.

Good thinking! I have a cat5 cable attached to a RJ45 to DB9 and bare wires on the other side. It is a pain to try and get bare wires into the Din 8 connector on the NEC so I was looking for just the DIN 8 connector. Looks like the digikey link is the right connector! thanks!

Why not just order it from NEC? That's where I got mine and it didn't cost much.

I just brought the NEC manual to a local electronics hobby shop and they made me one for $10. Of course, it didn't work and I had to take it apart and switch 2 of the connections.


I am not sure if the guy at the store screwed it up (I brought it back twice and he swore that it was wired exactly as the diagram showed), or if the NEC manual had a printing error, but I searched the forum for possible solutions, switched 2 wires and it worked.
