What you are going to have the most problems with, is locating the collectible. You need to land on a small balcony, from which you can see two objects attached to the wall - a chest and a control terminal. Use the cryptographic sequencer onto the terminal to determine the password (QUANDARY). You may now collect the Datapack.
Land onto the rooftop with the chest and the generator on it. Start by using the Shock Gloves on the generator, which will result in its being activated temporarily. Quickly, select the Remote Controlled Batarang from the inventory, turn right and throw it into the discharges shown in the screenshot, which will charge it. You only need to direct the batarangs into the fuse box neighboring the chest with the collectible, and collect the Datapack.
Start to the West of that collectible, jump off the Ace Chemicals rooftop and start to glide. Fly towards the weakened fragment of the wall, shown in the above screenshot, to cut through it. Afterwards, take the Datapack.
Locate the area with the generator, and the five pressure plates, shown in the above screenshot. Start by charging the generator with the Shock Gloves. You now need recreate the pattern of the green lights so, walk over the pressure plates (counting from the left to the right) 1, 3 and 4. You can now use the claw to collect the Datapack.
Do not follow the map's readings, because the collectible is in the sewers, i.e. in the location that you explore for the first time while completing the Locate the tracker placed on Bane main mission. By way of reminder, the entrance to the Park Row - Sewers is in the Western part of the Park Row district (the above screenshot) and you can get there by taking the door located on the right of the blocked off tunnel.
Approach the large vertical shaft shown in the above screenshot, and start by throwing the remote controlled Batarang. Send it towards the hole in the fence and make it hit the green button.
This is not the end, yet, because you additionally need to extend a rope, using the grapple and jump onto it, using the hook. Walk over the rope to reach the Datapack there.
