Sensor incompatibility

[Richrfl]

I have some kind of weird problem. I have two models with the same kind of sensors, however, one has an SP10 Plus receiver and the other the good old X8R, both running under an X18 transmitter. The installed sensors are MLVSS, GPS, and Variometer. All the same model. I tested the Airspeed sensor on the model with the Plus receiver and it works fine. When I try to install it in the other model, it messes up with the MLVSS. In this case, the addresses are MLVSS 09 0300 and Speed sensor 09 0A00. With that in consideration, using the Changer Changer, I tried to change the MLVSS address to 01 0300 (same as the one installed in the other plane that works), and several other addresses, but as I changed the address, even though I am careful not to use the addresses of the GPS or the Variometer, either the new address will mess with them, or, in the best case, it will give me a conflict warning and the MLVSS will not report any data.
Can some wise person give me some lead on where to look, which address should I use, or how to have these sensors working like nice the guys they should be?
For more information, the GPS address is 03 088 and the Vario is 00 0100
Another interesting observation: In the Channel Changer I have to set the address to 10, for the MLVSS to show me 09 on the transmitter screen. (??) (I kept this "shift" in consideration when I assigned a new address to the MLVSS).

I have never needed to play with changing sensor address. The only time this is required for instance is if you are running two MLVSS. You don't mention anything about radio or receiver, or sensor firmware versions. Decimal 10 is 09 in binary format.

Thank you for your feedback, Henny. This is not my first time having to change addresses. Normally, all devices come from the factory with the same address, however, in this case, I found that I have two MLVSS with different addresses, and the one in question happens to have the same address as the Airspeed sensor which is obviously the cause of the problem. Knowing that the one that seems to have the "wrong" address is the MLVSS, given that the one that works has address 01 0300, I guess I have to change the 09 0300 to 01 0300.
First, I want to respond to your question about the FW of the involved devices;
X8R ACCST 2.1.0 FCC
GPS ADV 1.7
MLVSS 20220630
VARIO VARI_ADV 1.5
PITOT ASS70_20230404
TX TANDEM X18 1.4.11 FCC
TX INTERNAL MODULE TD-ISRM 2.2.4 FCC

Well, thanks to your comment about the decimal to binary, even I do not understand how you convert a decimal 10 to binary 09, as for me it looks more like 08, I changed the MLVSS address from the device config out from the Telemetry screen to 01 and now everything works perfectly.

Decimal 10 is 09 in binary format.

10 (base 10) is equal to A (base 16)
10 (base 10) is equal to 12 (base 8)
10 (base 10) is equal to 1010 (base 2)
