Set up a grader device
Put CenterAide on a center device and link it to your plan with a short code. Nobody types your password on the device, and you can switch it on, off, or sign it out from your own computer at any time.
Before you start
Linking is done by the center's billing owner, from their own copy of CenterAide.
- Your computer: CenterAide installed and signed in as the billing owner. That is the account that pays for the center, or that started its free month.
- An active plan: a paid CenterAide plan or the free first month. The Devices section only appears when the plan is active.
- The grader device: Google Chrome, and the Chrome profile staff will grade in. Each Chrome profile is linked on its own.
- Both online, and within reach: you will read a code off the device.
1. Install CenterAide and get a code
Do this on the device staff will grade on.
-
Install the extension
Open the CenterAide page on the Chrome Web Store, click Add to Chrome, then Add extension.
-
Pin it to the toolbar
Click the puzzle-piece icon at the top right of Chrome, find CenterAide, and click the pin so its icon stays visible.
-
Choose “Sign in with a code”
Click the CenterAide icon. On the sign-in screen, click Sign in with a code. An 8-character code appears:
Leave this window open. The code works for 10 minutes; if it runs out, click Get a new code.
2. Type the code into your Devices
On your own computer, signed in as the billing owner.
-
Open Devices
Click the CenterAide icon, then open Devices in your account view. On Class-Navi you can also use the corner menu: Settings, then Devices.
-
Type the code under “Add a device”
Type the 8 characters from the device. The dash is already there, so just type the letters and numbers. It links on its own when the last box is filled, or click Link.
Codes never use 0, O, 1, I or L, so there is nothing to mix up. Pasting the whole code works too.
-
Pick the center, if asked
If you own more than one center, choose the one this device is for under Which center is this device for? and click Link again.
3. The device signs itself in
-
Check the device
Within a few seconds the device shows This device is linked. CenterAide is ready. Its popup now reads Linked to followed by your email.
-
Open Class-Navi or K-SIS
Refresh any Class-Navi or K-SIS tab that was already open. The CenterAide button appears in the bottom-right corner, and clicking it opens the tools:
That's it. Repeat steps 1 to 8 for each device. New devices are named Device 1, Device 2 and so on; rename them in Devices so you can tell them apart.
Invite an assistant by email
When an assistant uses their own computer, send the code to them instead of reading one off their screen.
-
Send the invite
On Class-Navi, open the corner menu, then Settings, then Devices. Under Invite an assistant, type their email, and a name if you like, then click Send invite. The popup's Devices section has the same box.
-
The assistant installs CenterAide
The email has a button to the Chrome Web Store and an 8-character invite code. They click Add to Chrome, then pin CenterAide to the toolbar.
-
They type the code
They click the CenterAide icon, choose I have an invite code, type the code and click Join. Their computer is signed in right away and appears in your Devices list, where you can switch tools on or off like any other device.
An invite code works once and lasts 7 days. Until it is used, it waits under Invite an assistant in Settings, where Send again emails a fresh code and Cancel stops the old one working. Replies to the email come to you.
Manage your devices
Switches, names and sign-outs are in Devices in your CenterAide popup. What each device may use is in Settings, then Devices, from the corner menu.
Turn a device on or off
Flip the switch next to a device. An open page on that device changes within about 15 seconds, no refresh needed.
A device you switch off shows nothing at all, not even the corner button, until you switch it back on.
All devices at once
The All devices switch turns every linked device on or off together, for example at closing time.
Rename
Click Rename to call a device something useful, like “Front desk” or “Grading 2”.
Sign out and remove
Sign out removes a device from the list and signs it out. Sign out all does this for every device. Linking one again takes a new code.
Choose its tools
Under Tools on each linked device, tick what a device may use: the Auto Grader, study plans, the K-SIS tools, Set a test. It hears the change within about 15 seconds.
Choose what it grades
Under What each device sees on the marking list, click Set to hold a device to certain levels and kinds of work. On that device the filters show a lock and cannot be changed.
For staff at the device
The button in the corner
Click the CenterAide button in the corner of Class-Navi or K-SIS, or press Alt+A, to open the tools. The switch at the top turns CenterAide off on this device only. Other devices are not affected.
What a linked device can do
Grade and use the CenterAide tools the owner allows for this device. It cannot change billing, link other devices, or see your other centers.
Unlink this device
Click the CenterAide icon and choose Unlink this device. The owner will need to link it again with a new code.
“Turned off by your center”
The owner switched this device off. Ask them to switch it back on in Devices. If the device is moving to another center, click Link it with a code.
Troubleshooting
I don't see Devices in my popup
Devices only shows for the center's billing owner while the plan is active (paid or in the free month). Check that you are signed in with the account that pays for the center. If the plan has lapsed, subscribe first.
“That code is not valid or has expired”
Each code works once, for 10 minutes. Check the characters against the device's screen, or click Get a new code on the device and type the new one.
“Too many wrong codes”
After too many wrong codes in an hour, linking pauses for a while. Wait up to an hour, then try again with a fresh code from the device.
“Choose which center this device belongs to”
You own more than one center, or you are working in a center you don't own. Pick the right center from the list that appears and click Link.
The device is linked but there is no corner button
Refresh the Class-Navi or K-SIS tab. If it is still missing, check that the device is switched on in your Devices, and that CenterAide is turned on at chrome://extensions.
A staff member uses a different Chrome profile
Each Chrome profile is its own device to CenterAide. Install and link CenterAide in that profile too, following the same steps.
Still stuck?
In the popup, click Report a bug, or email support@centeraide.com with the device's name from Devices.
