Look forward to seeing the results Woody. I also look forward to seeing the list of coils that can be used for the SDC too. If anyone wants a Dongle so they can use any coil on their SDC do we just send you a Coil so yourself or David can Calibrate a Dongle to fit the said coil?
I agree with Benny on the pain; I had to open a Minelab 18 inch coil and isolate the graphite shield from the coax shield and run a separate graphite shield wire out to the dongle pin 7 / blue wire. Otherwise if the shield remains connected to the transmit coil it may induce some of the pulse energy into the receiver chips that appear to have a separate/isolated signal ground. The GPX 6000 17x13 mono connector has the following pinout; 1 = white; mono Xmit center conductor 2 = coax; mono Xmit shield 3 = jumper to pin 2 inside 10 pin male plug 4 = no wire here but used in 14 inch DD coil for receiver shield 5 = NC 6 = black; ID chip 7 = blue; EMI/graphite shield 8 = no wire here but used in 14 inch DD coil for receiver signal 9 = red; ID chip 10 = NC I think the ID chip is a two wire device; otherwise if it needs a ground it must be connected to the blue/EMI lead or the mono shield.
Thanks for the info, I am going to run many experiments on the ground and shield as to see if the idea to use any coil can be simplified, as most but not all detector users run mono coils I am thinking to look at mounting the dongle inside the detector, also investigate putting the DD one inside as well as the Mono with auto detection.
@@DetectorMods The dongle ID chip and cable interface wiring and ferrite enclosure are encapsulated in epoxy. Maybe you can read the contents of the ID chip and burn a replacement chip?
@@chetburress3839 My thoughts are they are using a rolling code technology and thus it may be impossible to get around, but most designers I know put a back door into the design so they can test the function without the dongle, it is a matter to find how this may have been implemented, such as bridging a couple of test points or something similar, I once got around a security handshake by shoving 5 volts peak white noise into the data connection, also found the bridging to get around the handshake on many security products, I find the data point by probing between likely points with a 1k resistor to avoid damaging anything.
DD coil chip does work with mono coil ..just bit touchy Did u get the pic of my dongle woody ..sent to your site..made it couple years back .. 6000k made very well interesting concept Cheers Geoff
Internet is good when you have good people around your channel, your so lucky as you just don’t find gold in pomy land. I have just got a basic minelab just for going to the beach 😊😊😊😊😊
This modification is not feasible. Conventional mono coil shielding systems and coil cables are connected together at one end. The GPX6000 coil shielding system is a separate cable entering the control box. Pain
