with the serial hooked up, type "config"
That will show all the current variable settings.

Now type:
pc-time 40
save

That will set the precharge time to 4 seconds. Then it will save it to eeprom. Now turn off the controller and on again, and the main contactor will close after 4 seconds.
PAUL!!

Im ashamed of you.

The creator of the controller doesnt even kow all of the commands!!

Mike, If you just type restart, the controller will reboot without needing to cycle the power.

P.S. Im just pulling your leg Paul, Your doing great!!

Hi Jack! Once I found out that the stupid, stupid, stupid, um... stupid DC-DC that I was going to use doesn't work as a high side driver supply, I fell into a deep depression, and forgot to send it, since I really doubt that it will work anyway. hahaha. The good news is, I finished the next version of the control board which has a high side that should actually work now (and has rs232 and CAN). If you want one of the other boards still, I can send you one, but pwm'ing the high side almost certainly won't work on this board, if you are above like 12v for the power section. Joe tried it and it kept latching up his microcontroller.

Actually, I need to see if they still exist, since I may have thrown them in the garbage, on account of my anger. hahahaha. I'll look around the room and see if my wife pulled them out of the garbage.

Adam............... I may not know all the controls, but at least I um..... can make a really crappy SR board that doesn't work! hahahahaha. I swear I'm over the anger of the stupid ugly, control board that doesn't work... Unbelievable. It doesn't work! I'm a simple man. A man who wants... Nay! Needs a Synchronous rectification control board that works!

Here's the new one. It has some surface mount parts on it though. (resistors and caps is all. 0805, 1206, 1210). I watched a video on it on youtube, and soldering didn't look so bad anymore. You just need solder flux.

Hey Paul, do you have a schematic of the SR control board I could look at?

I have learned a few things from designing the power section of a 3 Phase Inverter that can be applied to a SR controller, so maybe I can give a few hints.

also is the schematic on the wiki up to date?

I've been spending a lot of time pouring over it, and the mechanisms in it. I'm re-reading the entire thread to see If it can answer the questions before I bug everyone. I am coming up with many questions regarding the design.

I think the wiki schematic is up to date for rev. 2C. The australians done made their own improved version, though.

I don't have a good way of posting the schematic in picture form. It's too dang big. any suggestions?! my crap software won't allow it to be saved as a pdf.
