The GMC-600+ manual states the following (below) about Data Ports (earphone type plug and the USB port) with regard to for hookup of 3rd party devices and data communications. I've hunted around, but not really locating anything, wanted to see what other's experiences are using those ports, and where to get the RCA cable for it, and further if these support external Geiger tube wands? Thank you.

Other technical details you may want to know
Data Port
This model has a 3.5mm analog data output port. It uses standard 3.5mm audio stereo plug, This port
is not for the earphone. The audio signal is for third party device and software. The signal can be
connected to other devices or computer microphone port directly.
USB Port
The USB port is the standard mini-USB port. It is used for data communication, external power and
the battery charger connection. |

"Data Port" is really a Grand word for what is nothing but an audio output. You can plug your earphone in (no matter what the user guide says), and you will hear the Geiger clicks even with the speaker switched off.
The output without a click is about +100mV, at a click the pulse reaches down to about -1.5V (minus!), with an irregular shape.
You can also connect this "Data Port" to a "third party software", like my GeigerLog, and record the audio-Geiger-clicks with GeigerLog.
This is explained in the GeigerLog manual (chapter AudioCounter Devices) and also in several articles demonstrating multiple applications in the real world:
"AudioCounter Support in GeigerLog",
"Review Geiger Counter 'Smart Geiger Pro (SGP-001)'”,
"Using GeigerLog with Geiger Counter Module 'Radiation-v1.1 (CAJOE)'”,
all available on the Articles folder of my sourceforge site: https://sourceforge.net/projects/geigerlog/files/Articles/
Technically it also works on a Raspi, but there are limits, see in GeigerLog manual chapter "GeigerLog’s AudioCounter on Raspi4 (Buster)".
Beyond audio-clicks there is nothing else, in particular no external wands (which actually is not trivial to do properly).
