You’ll need the SN connected for the computer to read it. But not necessarily for them to interfere with each other. The transmitter sends the tank pressure data along with the serial number at the specified frequency (38KHz, IIRC). The computer just looks for that SN to determine if it should display the info. If multiple transmitters are sending data at the same time, the computer can’t understand what is being sent.I was under the impression that you had to have both SN connected to the same dc, then if they bumped heads you'd lose a signal. I didn't think that random transmitters could bump heads from other people? Were you all logged into the same transmitters?
Same principle if multiple parties are talking at the same time on the same VHF channel. You can hear them, just can’t make anything out.
