 Ok, so how do I put this Datashoek Pro 2 stick into global read-only mode? So I first have to unlock it. This button, push it one second, red LED, unlock button, the default admin P, 11223344 Ok, green light, 1, 2, 3, and now we are in admin mode, ok? Now, to set it in global read-only, so that neither the user, neither the admin can write on it, push 5 and 6 together, like this, then the unlock key, and now it is in read-only mode. I can exit this mode, like this, and now it is powered off, and then I just need to power it on again, unlock it, and now the green light, it is unlocked, and this is in read-only mode. I can use it. So the 6, letter O, read-only, the O stands for read-only. If you want to put it back into read-wide mode, global read-wide mode, then you have to do the same procedure, but 5 and 9, 9 W write, instead of 5, 6, 5, 9, same procedure.
