Do coils with the same Khz work ??.

[walther24]

Has a Tx and a Rx , like a + and - . ??

[walther24]

Transmit coil: Cold end = Pin 2, hot end = Pin 5.

Receive coil: Cold end = Pin 1, hot end = Pin 4.

What does cold and hot mean ??.
How do you know what is what ??

[homefire]

I would assume the Cold end would be Ground. In most cases Negative.

Tomorrow i will take apart the detector.
So that i can see all the wires.
Then i will take of the coilplug , see the colors and the pinlayout.

I will make some pitcures and post them here.
Hopefully we can work the puppy out !!.

[walther24]

I,m back.
This is the coilplug with the Omhs.


This is the detectorprint with cablecolors


The coil has 4 wires ,with no ground in the plug.
So a bit like 2 of this cable below.


Anyone seen this setup before ??.
This is the coilplug.


What coils has the same setup for my 12.5 Khz coil ??.

Looks like you have it figured out. The non insulated wire is your ground. Most likely tied to the shield in housing.

[walther24]

Yes. Looks lile it.
But now the big question : Are there simelair coils with this type of connectoins ??.
Or most i use the ones from Mikron only ??.
You been a super great help for me , Homefire !!.
For now , Thank you so must !!.

[homefire]

Connects can be had or use the old one.

Discovery Treasure Baron.......12.5 kHz\par

Tesoro Compadre.....................12 kHz\par

Tesoro Tiger Shark...................12.5 kHz\par

Mikron is trade mark of the bulgarians. they did DP and novaday use this name. you have to draw TX driver/generator from the PCB
and will get representation what coil you need.
bulgarians are absent in the forum (the full ignorance of forum life) and will not give you usefull suggestions.

[walther24]

Draw TX driver/generator from the PCB ??.

I,m totally new at this.
What does that mean and how to do this ??.

[walther24]

Does anyone know what het blue component is with the screw ??.
Within the green circel.

It's a 100k multi-turn trimmer, similar to this -> http://uk.farnell.com/vishay/043p104...ohm/dp/1055460

[walther24]

Ok. what does it do ??.

[homefire]

With out seeing the PCB Tracks we don't know. Seems to be associated with 4053B Bilateral Switch , Ne555 Timer or the PIC. Micro Controller. Could be for Timing, Level control or Voltage Divider to be triggered on ? Need photo of other side of the board. I see one track looks like it comes from it to the 4046 Phase Lock Loop chip. Could control Error control signal for phase detection ? How about a photo of the Reverse side ?

[walther24]

I will seach for a reverse side photo.
