A user has provided me with details on the GMC-800 for proper integration into GeigerLog. If you want to follow see pre-releases pre67 and later on the "GeigerLog Development Versions" site: https://sourceforge.net/p/geigerlog/discussion/devel/
The GMC-800 manual still encourages "Third party software developers", but unfortunately points to a document of over 10 years ago, which is no longer valid for the 800 :-(
@EmfDev: could you post an update to that document GQ-RFC1201 ? If not, could you at least post the new memory configuration and explain which commands are no longer supported, or have changed in what way?

Most of these are not used like the old calibration and alarm. And the save threshold also are not used anymore. And disregard the numbering.

Thank you!
I see quite a few commands, which did not exist before GMC-800, and so are not described in your GQ-RFC* documents. Are they documented elsewhere? Can you provide this doc?
I am missing on those Commands: DSID SETVOICEVOLUME SPI_ID SPIPW SPISE SetSPISA GetSPISA
Is the endianness "Little" or "Big"?
Dumping the "save threshold" opton is surely a good change!
Can the tube voltage still be read-out? From what I saw I believe you can only set numbers on an arbitrary scale (like: Level:47) but still need an High-Ohm DVM to actually measure it?
I am realizing now that this counter has no WiFi? Too bad.

This looks like a really major problem. From the GMC-800 manual, page 5 (I leave the big size, so you can really see what the manual says!):
The background of the counter, even without any external radiation, is somewhere between 0 (zero) and 2 CPS? This is zero to 120 CPM?
So the counter creates a background, which could be over 6 times what older counters have as background, namely around CPM=20.
Really?

In the user manual for the GMC500+, the instrument background is <3 pulses/s (up to 180 CPM), so the GMC800 is "more precise".
I suppose that is an errata and it refers to < 3pulses/minute. |

The SPI commands are for the memory storage. Some are not useful.
DSID - 2nd part of serial number sometimes needed when upgrading firmware SETVOICEVOLUME - replaces speaker volume 0-15. holding the back button will readout the radiation reading. SPI_ID - returns the spi eeprom chip id. Not really useful for users SPIPW - eeprom page write SPIPW[adr1][adr2][adr3][number of bytes highbyte][number of bytes lowbyte] then followed by data SPISE - erases sector of the spi chip. SetSPISA - sets memory save address GetSPISA - gets current memory save address

Does it mean the counter is talking to me? Looks like some programmer had a fun day ;-)))

Does this allow for a faster erasure of the whole memory by writing to address 0, 0, 0 all 2 MB of 0xFF? Presently erasure had only be possible by erasing sector after sector, which is rather slow, and you have just doubled the memory.
What I would welcome is a command to the counter like "Are you talking xyz?" with a response yes or no. Feel free to add some icing, like command format (see the SPIPW statement) and lenght and format of the response. This could replace your RFC documents; which were last updated 6 years ago! ROM-size should not be an issue, when you can store speech info!
Speaking of response: what is the length and format of the DSID response? |

Yes, the device will read out the reading in CPM, µSv/h, mR/h, or in CPS. The voice data is stored on a dedicated voice chip. There is a function on the eeprom to erase the whole chip but surprisingly, it was not added to the commands. |

I ended up ordering a GMC-800 to figure it out myself.... Guess what I found?... GETCPM is not 2 bytes as listed in RFC1201... it's 4 bytes.
b'<GETVER>>'
b'GMC-800Re1.08'
b'<GETCPM>>'
b'\x00\x00\x00\x0c'
b'<DSID>>'
b'\xac\x994569\x03\x06'

Hi wikilicious, the GMC-800 uses 4 bytes as 2 bytes are not enough for higher readings as it can only go up to 65535. The original RFC1201 was made for the old GMC-300 and 320 models. But now all of them are updated and are using 4 bytes. I will forward this to support for them to update the user guide. |

@EmfDev Can you clarify? Are you saying Models 'GMC-300', 'GMC-320', etc. which are documented to follow RFC1201 may be updated to not follow RFC1201? Or... specifically, just GMC-800?

The GMC-800 should be using a different protocol than RFC1201 because of the CPM difference. |
