Thanks for your reply!
Evangelic message? :o I have not seen this, only text I have seen is the pinmarkings TX, RX, AN, PW and so on.
From MaxBotix FAQ:
6b) Control the MaxSonar®-EZ1[ch8482] Sensors to Range at the Same time (works for most instances)
Connect all the MaxSonar®-EZ1[ch8482] RX lines together, and connect to your control circuit such as a pin on a microcontroller (or even a 555 timer set up to strobe high for at least 20us with, a period between strobes of 50mS or more). Then start all the MaxSonar®-EZ1[ch8482] sensors at the same time by pulling the RX lines high for 20uS (or more but less than 47 mS). You can repeat this every 50mS or more. This will sync the MaxSonar®-EZ1[ch8482] sensors to take readings at the same time. The MaxSonar®-EZ1[ch8482], because of continuously variable gain, will ignore (in most instances) adjacent sensors. This method is especially convenient when using the analog voltage (AN output), as the analog voltage can be read at any time (i.e. the user does not have to wait for the output).
I think I might try that.. When I ground the RX line of a sensor, it always reads 0 but if it is pulled high it reads normally. Hooking them together using the RX-lines will make them all send their signals at the same time, and this somehow allows the sensors to be read at the sime time. I can't really get the physics of it to work in my head, but if the produser says it works...
So basically, I hook them all up to power and ground, one analog input each and all the RX lines to the same digital I/O line. The I/O line is pulled low by default, but is then pulled high for somewhere between 20uS-47mS. 47mS should be plenty to get readings from the 3 analog pins that the AN-pins of the sensors are connected to, right?
Have I got the idea right, or is my head just acting all screwy? :P
