Schematics?

Hi Guys-

I just got my MJLJ V4 in the mail! I'm very excited to get this project up and running...

Are there schematics availible for the MJLJ? I tried seaching the website but could only find people referencing that they were looking at schematics, and for older versions at that.

I didn't get any in my box.

Thanks

I am working on getting that uploaded to the wiki, likely this evening.

In the meantime, you should find all of the guides in place: kit assembly, vehicle install and operation under the 'how to' section of the site.

Kit assembly guide is sill a work in progress, but complete enough to get you going.

Thanks a lot Brent.

I was just curious what the purpose of D4 and D5 were. I'm used to those being configured for forward TVS protection. These look like it was for reverse transient protection. Is that true?

Thanks

Oh- and what should the pinout connection be for the RJ-11 to DB9 connector? I couldn't find that on the wiki anywhere... '

Thanks again.

Here is the info on the serial communications pinout:

Schematics have been added to the downloads area:

D5,6 and 7 are there to protect the processor input pins from the wild world of outside electrical signals. D4 provides a degree of reverse transient protection.
