In past iterations i think maybe you could see the colour change on the teleport wire. now theres an X to show its been placed on the first teleporter. The trick is to use the power line first. Connect the power line to your origin teleporter and you still get a visual. The line will be green and it will turn red as soon as youre out of the 200u range, Giving you an indicator to place teleporter 2 within that limit. Hope that helps.
Further to that i used to link teleporters using the wire glitch to have them facing each other and you can get a passthrouh right to the end of the chain. This could go as far as base limits in one jump, i did like 5 or or 6 to travel 1000u at once to some sky bases i did. theres screenshot with co ords, although for visitors seems the electricity meter is broken unless you teleport direct to the base these days, but you get the idea
. Just messing about with another old base.
