1. Flash AJKFi

One file, uploaded in the EDUP settings page. No extra tools - a PC and one network cable.

1. Before you start
   Download the AJKFi file above and check its size. If your browser saved it with (1) or any bracket in its name, rename it back. Connect the PC with a network cable to a LAN port, PC network on automatic.
2. Open the EDUP page
   Open http://192.168.1.1 and log in (user root, no password on a new unit).
3. Upload AJKFi
   System → Backup / Flash Firmware → Flash image...: choose the AJKFi file, untick Keep settings, then Continue. Do not switch it off.
4. Wait about 3 minutes
   It writes and restarts on its own.
5. Check that AJKFi is running
   Unplug the PC's cable and plug it back in. The Wi-Fi AJK PISOWIFI appears and the admin page opens at http://10.0.0.1:8080. Carry on with 02 Activate.

2. Activate

1. Plug in the internet
   Put your internet cable into the router's WAN socket. The router needs to reach us once to collect its licence.
2. Open the admin page
   Connect to the Wi-Fi called AJK PISOWIFI, then open http://10.0.0.1:8080. Sign in with admin / admin.
3. Activate
   Open System. If you sent us your Account ID when you bought, press Check In Now and the licence arrives by itself. If you were given a licence code, type it in instead. The page shows Licensed when it is done.

3. Set the admin password

1. Change admin / admin
   Go to Settings → Admin Account and set your own password. Anyone connected to your Wi-Fi can reach this login page, so do it before the machine goes out.
2. Put the dashboard on your phone
   Open http://10.0.0.1:8080 on your phone. Android (Chrome): menu ⋮ → Add to Home screen. iPhone (Safari): Share → Add to Home Screen. It gets the AJKFi icon and opens straight to the Dashboard.
3. Open it from anywhere (Cloud Remote)
   Sign in at ajkfi.com, open My machines and press Remote - the dashboard opens already signed in, from anywhere with internet (AJKFi 3.55 or newer, Lite 1.4 or newer). Give the machine a name there with Rename. Remote can be switched off on the router under Network → Cloud Remote.

4. Name your Wi-Fi

1. Name your customer Wi-Fi
   Network → Wireless. Rename AJK PISOWIFI to your shop name. Leave it open - customers pay at the portal, not with a password. Name it before you open: the name cannot be changed while a customer with running time is connected.
2. Add a hidden Wi-Fi for the coin slot
   On the same page, under Add Another SSID, add a second SSID on the 2.4 GHz radio, tick Hidden, and give it a password - required, the coin slot will not join a Wi-Fi without one. 2.4 GHz matters: the coin slot board cannot see 5 GHz.

5. Connect the coin slot

1. Flash the board
   Easiest: open ajkfi.com/flash (the ESP8266 Online Flasher) in Chrome or Edge on a computer, plug the board in with a USB data cable and press Connect and flash - choose New board for a new one, Update for one already in service (it stays paired with the router). Or use PyFlasher or NodeMCU Flasher: 115200, DIO, erase yes on a new board, no when updating. From coin slot 2.5 on, later updates come from the router: Settings → Coinslot Hardware → Update coin slot.
2. Pair it with the router
   On the router tap Pair coin slot in Settings → Coinslot Hardware, then power the board. A coin slot 2.9 or newer finds the router by itself: within about a minute the router shows Paired - no phone, nothing to type. Then set the lock to Active HIGH in Settings → Coinslot Hardware → Coin acceptor wiring and tap Save to coin slot. Older board, or two machines pairing at the same time: join the board's own Wi-Fi AJKFi-Coinslot-Setup from a phone, pick the coin slot Wi-Fi, type its password, set the lock mode to Active HIGH and press Save & connect.
3. Wire it
   Three wires from the coin acceptor to the ESP8266 board: COIN to D6, SET (the lock wire) to D7, and GND to GND. The ground wire is not optional - without it the coin slot counts coins that were never inserted. The 12 V adapter runs the acceptor and the board together through the base board's DC socket.

   

4. Test it and put it in the box
   Insert a real coin through the portal and watch it appear. Then drop a coin without tapping INSERT COIN: it must come back out - if it is taken, switch the lock the other way in Settings → Coinslot Hardware → Coin acceptor wiring on the router and tap Save to coin slot (coin slot 2.4 + AJKFi 3.45 or newer; older boards: on the board's setup page, hold its FLASH button 3 seconds). If coins go in but no time is credited, try the coin signal (D6) setting there the other way. The wires do not change. Then mount everything in the box and test one more coin. Swapping in a new board later: tap Pair new coin slot in Settings → Coinslot Hardware first.

6. Recovery and going back to EDUP

1. No 10.0.0.1:8080 after 10 minutes
   Set the PC to 192.168.1.2 (mask 255.255.255.0). Unplug the router, hold Reset, plug the power back in and keep holding until the network light blinks, then let go. Open http://192.168.1.1 and upload the AJKFi file there.
2. Newer AJKFi versions
   They arrive as online updates on the router itself. No file to upload again.
3. Back to EDUP RT2983 Stock Firmware
   On an activated router with internet on its WAN port: System → Firmware → Check for Firmware, choose EDUP stock under Back to EDUP EP-RT2983 Stock Firmware, Download & Check, then type FLASH. This erases AJKFi, its sales and settings - take the Database Backup first. After about 3 minutes it is a factory-fresh EDUP at 192.168.1.1 (user root, no password).
4. Coming back to AJKFi
   Upload the AJKFi file in the EDUP page, as in step 03. Your licence comes back with your activation code.
5. It will not start at all
   Message us on Facebook before trying anything else. AJKFi never writes to the part of the router that starts it, so it can be fixed on the bench.
