( I have a sick sense of humor) I want to pass on the cheapest and coolest method I've found to hook up the serial port on a LANDISK box PLUS my original setup. I've posted both methods.
The original method: I have a Plextor PX-EH25L sitting in the office which I ordered the day I saw mickey's post about. When I got it in I did the uber nerd h/w mod, cutting out a small section of the back plate below and to the right of the 10/100 ethernet cable. Here I mounted an "RJ10/RJ22" modular handset jack. They aren't really RJ cables as they were never meant to connect to the PSTN. Anyway, I connected the handset jack wires to the Vcc/Rx/Tx/Gnd pins at the front of the board. Then I plugged in the cable I use with other embedded systems, which has a MAX3232 serial line level shifter chip in the 9pin serial connector. The cable is available prefab(cost US$20), all you have to add is love<BS><BS><BS><BS> a handset plug. The cheap / coolest method: Buy a cell phone USB data cable, I got two,shipped, for under US$6. I used a "Futuredial USB Data Cable". Remove the little PCB enclosed in a wide spot in the cable and solder Rx/Tx/Gnd to the pins at the front of the board. The neat thing with this setup is it's USB, so you don't need a serial port on a notebook AND the Prolific chip is powered off the host USB. BTW, the second method is probably already well known to anyone who's done any Linux hacking on small wireless routers. Anyway, just thought I'd pass on some LANDISK serial port hacking to the misc@ crowd. g.day diana On Thu, 9 Nov 2006, mickey wrote: > On Wed, Nov 08, 2006 at 03:57:30PM -0700, Diana Eichert wrote: > > On Fri, 6 Oct 2006, Diana Eichert wrote: > > > > > On Sat, 7 Oct 2006, mickey wrote: > > > SNIP > > > > woman you are fast (: > > > > there is supposedly a piece sold in .eu (see landisk.html) > > > > but then nobody knows for sure... it's a japanese sex toy. > > > > cu > > > > -- > > > > and once again I'm fast on the draw, I see a landisk directory showing up > > in the snapshots directory. > > > > ftp://iawnet.sandia.gov/pub/OpenBSD/snapshots/landisk/ > > > > I have a Plextor, just waiting for my 'sample' connector to show up so I > > can wire my rs232 line driver chip/cable to it in a pseudo 'production' > > manner. > > i didn't do it! > cu
