C.SCOPE CS2MX/CS5MX Schematic

[wallker]

Does anyone have a schematic?
The one i have is quite smudged in one section.
Tnx in advance.

Thanks kt, that's more than i expected.

Does anyone have more information about the coil(CS2MX)?
I do not think I have measured properly, because of the resistors that are strangely tied within the coil.
The connector shown on the picture is on the cable side.

The attachment it doesn't open

[wallker]

I open it without problems, try again, if it does not work I'll upload it again.

It opens ok for me.

low value resistances between TX and RX seems very strange for me. something wrong.

[dbanner]

I think the tx is centre tap coil?(cs2mx scheme)
The centre tap of tx and one end of rx are both connected to ground. I suspect this would be pin 1 of connector.
between 1(ground) and 5 and between 1(ground) and 4 you are effectively measuring each half of the tx coil. 4.4ohms sound about right.

It's strange indeed, i think there are resistors in parallel with tx and rx inside coil.

That first cross my mind, because of sch and equal resistance between pin 1(rx gnd) and pins 4 and 5.
But if it is center tapped coil, what would be a benefit of such setup?
I read somewhere that this is double d coil, so again i think there are resistors between tx and rx in parallel and maybe even between each end of tx and rx.

[kt315]

i did not see a coil with resistors in parallel. nonsense. you have to open the connector and make sure that there no unwanted connections inside.

[dbanner]

Wrong, you have to establish which pin is ground.
By placing probe on battery negative, then other probe on pin 1.
