whites coin master probe plug

[Orbit]

Does anyone know the pinout for the whites coin master coil or the layout on the RX and TX devices ?

I always have to be alone, here's the schedule!

Pin 1 -- RX-gnd
Pin 2 -- RX+
Pin 3 -- Shield
Pin 4 -- TX-out
Pin 5 -- TX-VCC

Ok Karl thanks !
I would say that the coil inside has a resonant capacitor on the rx, is my opinion correct?

[Carl-NC]

No, the Prizm/Coinmaster coils are just windings, no other components.

Hi Orbit,

When Carl mentioned the Coinmaster/Prizm coil is the same.. I had a prizm years ago and measured the coil

Rx = 13.25mH 15 ohm
Tx = 512uH 1.5 ohm

The 5 pin connections are the same as above. The cable is dual coax, like s-video

Thanks Altra, those are the numbers I recall.

Hi Altra ! If those are the inductances you mentioned, my inductance instrument gives a very slightly higher inductance rx 13.40uh and tx 590uh maybe my inductance device is a little wrong, but that's it ..Thank you Altra and also Karl!

Those are good values you have. Every inductance meter reads a little different.
