510 jtag question

[HILLBILLY]

putting in a jtag in the 510. just wondering if resitors are needed like in a simple jtag.
thanks

Sounds like you need to do more reading..... The 510 is one of the most difficult IRD's to mod, and one of the easiest to burn up.

Your question.... If you do a simple jtag, then yes the resistors are required. I used the simple jtag on mine and it works just fine.

thanks, i read alot, and nowhere does it say about using resistors in any of the 510jtag how to's. so it is like a simple, cool. i read on another forum that if the wire is less than 12", no resistors are needed, but i will put them, cause u are very right, they are the easiest to burn up! thanks for the help.

I believe the resistors are because the standard parallel port works on a 12volt swing, and the jtag output is 5V, the resistors provide the voltage drop to interface the different logic levels.

I could be wrong, but I believe that is the function of the resistors.

either way, i'm not taking chances with it, resistors are in!
0j1 in already. tsop lock installed for me(but now is where i am having issues after the lock). gonna do vidmod first, cause from wat i can see, there is a bottom side trace cut. then gonna put in jtag. gonna attach wire to the points, then the other end to resistors, to db25. gonna screw the db into the case, below the hd. cover will slide on no prob. then wen i need to program, i attach a female male extension to comp.

There is a top side trace cut also! I hope you are not looking at the 3 wire/1Cut vidmod, that is known to fry cpu chips! You want the 4 wire / 2 cut vidmod.

no no, i am doing the 4 wire 2 cut. just if i do a jtag first, then it would be hard to do the trace cut on bottom side after. if both cuts were topside, then no problem. my issue with the 510 is i inherited a bad one and i'm trying to figure it out. thanks for looking out!
