I have a Water Turbine/Calculation Module room connected to Research room via Network Cable. I have wanted to use the Laser Transmitters because they exist.
I have tried what I thought were the simplest setups to test them and nothing has ever worked. I gave up on them many versions ago and I asking now because I cannot reach Tyros.

I tried "both facing up"

I tried "both facing each other"

I tried them facing away but since the cable did not connect to the Transmitter, I did not take a photo.
I also tried them on top of each other separated by a distance of about 60 but that did not work either and I could not get a good photo.

For none of these did the Researcher indicate the 3 Calculation Modules were 'in use'. When the network is all cable, the Researcher indicates 3 Calculation Modules are in use.

I do not know if there is a bug here or if I just do not understand these lines in the E-Scanner

• transmitter and receiver have to be exactly on one line
• • line of sight (x & y or z & y being the same) ?
• • straight line with nothing between them?

it should work like in the 2d picture but it is not working. I am working on a fix.

YOu can now use the Escanner to check what stuff is connected to your network:

Please try futurepack-1.18.2-33.0.7260.jar

After I "learn" about this technology, I will retest. ;)

I have confirmed this works with 33.0.7260.
I did a further test with the two nodes separated vertically by placing ladders between them so as to traverse the span. Sadly iron ladders which do not appear to block the signal, do in fact, block the signal. I did not try wooden ladders of any kind. I am still happy to have it as it is.

I meant to say. I did expect the e-scanner to show what is connected to the entire network including both ends of the network transmitter, but as your image depicts, only each side is shown.
I will try at a later time having 4 transmitters in the path so that I can span horizontal as well as vertical distances.
