Pin1: TX+
Pin2: TX gnd
Pin3: Case gnd
Pin4: RX gnd
Pin5: RX+

Pins 3 & 4 are tied on the PCB.

Thanks Mr carl IS the red one Tx+ ?
And What about sp?cification oo coil 6" ?

[Carl-NC]

No, red is RX+. I don't know what coil you are asking about but the general specs for a GMT are:

RX = 3.1mH
TX = 280uH (Litz)

I don't know the exact wire gauges, probably ~28awg for RX and ~20awg for TX will work.

Coil

[hooby life]

When i test with multim?tre i found :
Pin 1 Pin 2 = 15.5 ohm
Pin 3?pin 4 = 2.6 ohm
Pin 5 not connect any were .

coil

That's a 5.3" concentric. Pins 1/2 is RX, pins 3/4 is TX.

Thanks so much Mr Carl . I Want to wanding a Big coil mor than 14" did this succ?de. Have you Anny iformation about this ?
Wires . Inductance . R?sistance . DD. Concentric .

[Carl-NC]

You have all the info you need: inductance and resistance of both coils. Try to reasonably match these.

[hooby life]

I have no information about big coil for gmt . Can use inductance and risistance of my 5.3"coil in dd coil ?

[Carl-NC]

Yes, you generally want to match the specs in post #5 no matter the size of the coil.

[hooby life]

Can i use .27 mm and 0.4 mm wire for rx and tx ..?
Can found a files or insrtuction 14" or 18" coil building . In here ?

You can use a coil calculator to figure out how many turns each coil needs for the sizes you want. Then you will know how long the total wire will be, and can calculate the resistance based on wire gauge. All this is stuff you can easily look up, you don't need instructions.
