MS Testing Help
Hi all, have searched and found nothing on this along side no advice of what to check if you don't get the reading you're looking for basically: i have build up my ms and only just got the stim plugged it and started carrying out the 'serial commucations testing'. I can get a cicuit at the U6 by bridging, however when i try and complete the circuit between pin 12-13 on the 40pin processor socket i'm getting nothing? so far as i can see these two pins (on U6 and U1) are connected by a track directly on the pcb so i don't quite know how to check it? there is continuity between them but still can't get the charactor to repeat itself on hyperterminal?
:facepalm: any help very welcome - Cheers. Jack edit - its a ms1 with the 3.0 board as per the guide on here :) |
I've never acutally built a MS by going through the manual steps; don't have 30 hours in a day to do all the steps it asks.
|
lol fair play, might just carry on regardless, i thought it was a pretty crap way to test it tbh, what would you suggest? cheers.

Heh. This is an interesting question. I also no longer use the assembly guide- Once you've got some experience doing these, it's a lot quicker and easier to just build off the schematic.
(With the exception of the MS3, since they won't publish the gods-damn, motherfucking, ass-raping, shit-eating, nerf-herding, testicle-shitting schematics for those. Not that I'm angry about that or anything.) So I'm having to guess a bit as to which steps you're doing here. I can get a cicuit at the U6 by bridging Perhaps you have mis-identified pins 12 and 13 at the CPU socket? It is, if I recall correctly, oriented upside down on the board (such that pin 1 is at the bottom right, rather than the top left.) Frankly, I don't even bother doing these tests anymore. It's a damned simple circuit, so I typically just go all the way to having the CPU in and powered up before I bother connecting a serial cable to it. I'm not suggesting you start skimping if this is your first build, just explaining that a lot of us who have built a bunch of these aren't familiar with the "proper" test procedures. :) |

cheers joe perez, i think i'm doing the bits it suggests, i'm pretty sure its all on there right, i think i am just over testing, i thought that pin 1 was top left, maybe i'm bridging the wrong ones on the cpu socket then, It's step26 on the megamanual. i'll start trying to get a map sorted and onto it then, just miss out the tests, its all soldered in and not shorted so it should be fine. Cheers for all the help. oh and am in England mate.
Cheers, Jack |

Near Cambridge, I suspect. |
haha that was random? and a bit off topic
|
So, am I close?
|
yeah, unless its in my profile obv? back on topic worth just manning up and getting it mapped? forget the little checks

back on topic worth just manning up and getting it mapped? forget the little checks I'd suggest you get the board finished down to step 40, at which point you can actually load software onto the CPU and have meaningful communications with it. That's sort of the point in the build where, if you're going step-by-step, you start to get into the custom circuit modifications for cam/crank inputs, ignition outputs, running leads across the board, etc. |
When I built mine I went through the loopback test in the megamanual because I was a paranoid noob. I don't think it's critical for testing the MS itself, because it's simple to build if you can solder and follow directions. But it was useful as a check that my USB-serial adapter was playing nice with my laptop and MS. I did have to install the adapter drivers a couple of times for that to work, so...... yeah.

right so have got the com port working, stim plugged in but megatune wont find it when i click realtime? the right port is selected etc :/ - again cheers for the advice
