OKAI Server Configuration
This guide provides step-by-step instructions for configuring OKAI scooters and e-bikes to connect to the Levy Fleets server. Whether you're switching from OKAI's default server or setting up new devices, this guide covers everything you need.
Levy Fleets Server Settings
All OKAI devices must be configured with these settings:
- Server IP:
137.66.36.122 - Port:
9002
Using incorrect settings will prevent your vehicles from connecting to Levy Fleets.
Required Software Downloads
Download these tools before starting configuration:
| File | Description |
|---|---|
| ZK Tool (ZK105LSC Manage Tool V1.2.4) | Main configuration software for reading/writing IoT settings |
| Modify Mode.exe | Switches IoT device between TEST and NORMAL modes |
| Encryp_Data.okai | Encryption data file required by Modify Mode |
| Prolific PL2303 USB Driver (v1.12.0) | USB-to-serial driver required for Windows 11 |
Windows Only
Both ZK Tool and Modify Mode are Windows-only applications. The Encryp_Data.okai file must be in the same directory as Modify Mode.exe to function.
Windows 11: Prolific Driver Required
This USB driver is only for computers running Windows 11, as it won't automatically recognize the COM serial port. You must install the Prolific PL2303 USB driver before connecting the OKAI USB debugging cable.
Video: How to Use Modify Mode
Prerequisites
Before you begin, ensure you have:
- A Windows PC (the configuration software is Windows-only)
- The software tools above downloaded and extracted
- IoT USB debugging cable (OKAI ZK1 series cable)
- Access to the vehicle's IoT module
Part 1: Update Server IP and Port
This is the most critical step. You'll connect to the IoT device and update its server configuration to point to Levy Fleets.
Step 1: Prepare the IoT Device
- Power on the vehicle and ensure the IoT device is active
- Press and hold the IoT device button for approximately 10 seconds to activate it
- The device must be in TEST mode for debugging software access
LED Status Indicators
| LED 1 | LED 2 | Mode |
|---|---|---|
| OFF | OFF | INACTIVE mode |
| Alternating Flashing | Alternating Flashing | TEST mode (required for configuration) |
| ON (Breathing) | OFF | Normal operating mode |
| OFF | Flashing | ECU fault detected |
| OFF | ON | IoT fault detected |
Step 2: Connect to the IoT Device
- Extract the IoT module from the vehicle housing (if necessary)
- Connect the USB debugging cable to the IoT device
- Connect the USB end to your PC
- Ensure no other applications are using the USB/serial port
Step 3: Switch to Test Mode (Modify Mode)
If your device isn't already in test mode, use the Modify Mode software:
- Close ZK Tool if it's running (to prevent USB port conflicts)
- Launch Modify Mode software
- Select the correct USB serial port from the dropdown
- Click Open Port
- Enter the device's IMEI number
- Click Confirm - the software will automatically switch the IoT to test mode
- Close Modify Mode when complete
Video Instructions
See the Modify Mode video tutorial at the top of this page for a walkthrough of this process.
Step 4: Configure Server Settings with ZK Tool
Now you'll update the server IP and port using ZK Tool:
- Launch ZK Tool software
- Log in with the current password:
Leoride2021
Password Security
The default OKAI password is Leoride2021. You should change this to zk200 for Levy Fleets compatibility (see Step 5 below).
- Press Ctrl + L to open the command entry page
- Send the following commands to configure the server:
Fixed-Time Reporting Configuration
AT+GTFRI=zk200,1,0,60,10,240,,,,,FFFF$
This sets the device to report its position every 60 seconds during active operation.
IP and Port Switch Command
AT+GTQSS=zk200,okai.co,,,,,,137.66.36.122,9002,,,,,,,,FFFF$
This is the critical command that points the device to the Levy Fleets server.
Verify the IP and Port
Double-check that you entered:
- IP:
137.66.36.122 - Port:
9002
Incorrect values will prevent the device from connecting.
APN Settings
APN (Access Point Name) settings are typically pre-configured on the SIM card. Only modify APN settings if specifically instructed by your cellular provider.
Step 5: Change the Device Password (Recommended)
For consistency with Levy Fleets, update the device password:
- Press Ctrl + L to access the command page
- Send the password change command:
AT+GTCFG=Leoride2021,zk200,,,,,,,,,,,,,,,FFFF$
- Exit ZK Tool
- Re-open ZK Tool and log in with the new password:
zk200
Step 6: Restart the Device
Apply the configuration by restarting the IoT module:
AT+QFCT=0803
The device will reboot and attempt to connect to the Levy Fleets server.
Part 2: Verify Connection
After restarting, the device should connect to Levy Fleets:
- Wait 30-90 seconds for the device to reconnect (time varies based on cellular signal strength)
- Log in to your Levy Fleets Dashboard
- Navigate to Vehicles or IoT Devices
- Verify the device appears online with updated telemetry
Troubleshooting Connection Issues
| Issue | Solution |
|---|---|
| Device not appearing online | Wait up to 5 minutes, check cellular signal |
| Device shows offline | Verify IP and port settings, check battery level |
| Commands not responding | Ensure device is in TEST mode, check USB connection |
| Password rejected | Use the default Leoride2021 first, then change to zk200 |
Part 3: Return to Normal Mode
Once configured and verified, switch the IoT back to normal operating mode:
- Connect via ZK Tool with password
zk200 - Press Ctrl + L
- Send the mode switch command:
AT+GTXWM=zk200,01,,,,,,FFFF$
The device will switch from TEST mode to NORMAL mode for regular operation.

Common Issues
Device Was Never Connected to OKAI Server
If the device never communicated with OKAI's original server, it requires physical access to configure:
- Charge the vehicle fully
- Verify the SIM card is activated and has data
- Check the IoT module is properly connected to the ECU
- Follow the configuration steps above
Device Has 0% Battery
Devices with completely depleted batteries cannot receive configuration commands remotely:
- Charge the vehicle until the IoT module powers on
- Once online, follow the configuration steps above
- For bulk deployments, OKAI may be able to queue the IP switch command to execute when the device comes online
Multiple Devices to Configure
For fleets with many vehicles, contact Levy Fleets support at support@levyelectric.com to discuss:
- Bulk configuration options
- Remote configuration assistance from OKAI
- Pre-configured device procurement
