Xenon RGH

[elski2001]

maybe i am trying to read into this too much but can the rev A coolrunner be used to rgh the xenon motherboard or do i have to order the rev B to do this..

Yes, but you need to add a capacitor.

As the thread states......

A 47nf ( 0.047uf) capacitor needs to be added between PLL_BYPASS(+) and GND(-). (If you have a genuine TX CoolRunner REV B you can use the on-board by bridging the CAP jumper)

A 220-270pf capacitor should be added between CPU_RST(+) and GND(-) on the cpld. (If you have a genuine TX CoolRunner REV B this is already included in the design so not required)

So your answer is YES, you can modify the CoolRunner Rev A .

You can use any rev but rev B has on board cap which is alot easier instead of searching for a 47cap or lower.

 

[elski2001]

well thats cool then.
i understood about the location of th 47nf but wasnt sure about the 220-270pf
and where does the other end of the double shielded wire go.
i know these questions may seem stupid to them in the know but surely its better to know what your doing before going full steam ahead.
Hope this thread help others!!!!

This thread contains images for each point.

I understand your confusion elski2001. The "other end" of the double shielded wire is actually just feeding through a whole to get to the top side of the motherboard and connect to the Coolrunner.

i must be missing something then because if i havnt looked once ive looked a million times lol
where does the 50ohm connect to on the coolrunner

Spoon feeding is bad for your health!! If you even looked at the picture its color coded. Your answer is right in front of you.

No mate, that picture is only for example and it is not for xenon, it is for phat d connection. If you have that wire, just connect it to the d connection - i.e. left pad of the cap you removed(C7R112)

I can't understand how this can be difficult ?

Everything is even color coded ffs lol

Uber you know you have to help them with everything

 

[ARUNCREATIONS]
