Chamber 9: Side Tracked

You'll start by needing to drop off the moving slider. The instant you do, you need to grab back onto it while it's moving. This is key to triggering the sensor beam. Immediately after that, jump left, over the sensor beam, to bring the slider back with you.

Next, head through the vertical teleporters on the ground floor and hit the switch. After that, drop down the left-hand teleporters. Then, drop down the right side of the sensor beam. This should send the slider up to block the doors above the Patroller near the terminal.

Now, hack the terminal. You'll need to time your move to the left with the Patroller turning around and heading upwards. If you're too slow, it'll spot you. Once that's done, drop back to the ground floor and flip the switch you just unlocked. Drop back down the far-left teleporter, then drop down the left side of the sensor beam again to bring the slider back. Drop into the lower-left teleporter once more, and then finally, drop down the right side of the slider.

All those moves should position the slider perfectly over the central terminal, casting a shadow that makes it safe to approach and hack.

With the central terminal dealt with, run across the ground level to the right side of the room. Jump up to get the Patroller's attention, and let it get a bit closer so it follows you. Then, drop down into the teleporters in the bottom-right corner.

You'll pop out near the exit. Drop down and quickly hack the right-hand terminal. The Patroller should still be looking away. From here, you have a choice: hack the middle terminal in the safety of the shadow, or if you want the [Helix], you'll need to follow the steps below to grab it first. If the Helix isn't your priority, hack the middle panel right after the first one. This way, you'll be done just as the Patroller starts coming back. You can then dash under it undetected and drop into the teleporter to the exit.
