301.013 Phone line jtag ?

[Rax]

I am wanting to do the phone ling jtag to my 301.013. My question is the jack that is already in thier is 0nly a 2 wire. From the info I have read you need 6 wire to work. But how do I install a 6 wire if there is only 2 holes in the board for the original? After thinking about it why couldnt I use an eithernet jack w/ 8 wires but only use 6? and not even use the holes in the board just run the wires strait accross to the jtag pads? Will this work? Also does any one know the part #'s for the 5 100 ohm resistors?

Thanks

That's a good idea! Just drill a hole in tha back panel of your receiver and run tha (CAT5) cable out thru that hole ( just long enuff to be able to plug in your modded J-Tag cable ) !

( or you could drill a hole in tha bottom of tha receiver (case) and solder tha wires to tha pads on tha bottom of tha board and have tha cable come out tha hole on tha bottom, but I think doing it on tha top of tha board would be tha best way to do it! )

Good idea. I was thinking of making it fit where the old one was w/ a little hot glue. But i wasn't sure if the ird would work if it didnt detect the phone jack.

I just drill 4 additional holes and mount a 6 pin jack in place of the existing one.......not hard at all to do.

Cool. Ok how about the 100 ohm resistors. Does any one have a part #? are they 1/2 watt, 1 watt, ect...

Thanks

1/4 watt , 100ohm. The Part # 271-1311 Radio Shack-set you back 99 cents. Some say 1/2 watt works as well, but can testify to 1/4 and not buffered, works great.

Thanx :)

Any watt resistor will work, even a 1/8 watt. Since 100 Ohm in not a standard, I used the 110 Ohm, and they also work. Be sure and put shrink tubing or something over the resistors so they don't touch together inside the Db25 shell.

The resistors serve a a current limit between the receiver and PC parallel port, to help prevent damage from either. The current flowing in this application is extremely small, 1/8 watt is plenty big enough. The only reason larger wattage is specified is for physical strength of the device, 1/8 watt are tiny and fragile.....but function perfectly.
