What is ADMS in ZKTeco?

ADMS stands for Automatic Data Master Server. It is ZKTeco's proprietary communication protocol that allows biometric devices to automatically push attendance data, user records, and logs to a central server (like ZKBioTime) over HTTP/HTTPS. Devices with ADMS-enabled firmware can connect via Ethernet, Wi-Fi, GPRS, 3G, or 4G.

How to update ZKTeco firmware using USB?

1) Download the correct ADMS firmware file for your device model. 2) Copy the firmware file to the root of a FAT32-formatted USB drive. 3) Insert the USB into the device. 4) Go to device menu > USB Manager > Upgrade Firmware. 5) Select the firmware file and confirm. 6) Wait for the update to complete and the device will reboot automatically.

How to enable PUSH feature on ZKTeco device?

After updating to ADMS firmware: Go to device menu > COMM > Cloud Server Settings. Set Enable Cloud Server to YES. Enter the server IP address (where ZKBioTime is installed). Set the server port (default 8081 for HTTP). The device will automatically connect and push data to ZKBioTime.

Which ZKTeco devices support ADMS firmware?

Most ZKTeco Green Label devices support ADMS firmware including: SpeedFace-V5L, ProFace X, xFace600, MB460, K40, K50, iClock, uFace, and many more. Check with your ZKTeco distributor for the correct firmware version for your specific device model and platform.

What is the default admin password for ZKTeco devices?

The default administrator password for most ZKTeco devices is 1234. For ZKBioTime web software, the default credentials are username: admin and password: admin123. It is strongly recommended to change these default passwords after first login for security.

ZKTeco device not connecting after firmware update - how to fix?

If your device does not connect after firmware update: 1) Verify the Cloud Server IP and port are correct. 2) Ensure the device and server are on the same network. 3) Check that port 8081 is not blocked by firewall. 4) Restart both the device and BioTime service. 5) Verify the firmware version supports PUSH protocol. 6) Try pinging the server IP from another device on the same network.

How to reset ZKTeco device to factory settings?

To factory reset a ZKTeco device: Method 1 - From menu: Go to device menu > System > Reset. Method 2 - Tamper switch: Power off the device, then power on and quickly press the tamper switch 3 times within 30-60 seconds. The device will beep and reboot with factory settings restored including default password 1234 and default IP.

What is ADMS and Why Update Firmware?

ZKBioTime software works with biometric devices whose firmware is built with the PUSH/ADMS feature. This enables:

Important: Without PUSH/ADMS firmware, biometric devices cannot communicate with ZKBioTime software. Manual data collection via USB would be required.

Step 4: Verify Update

Device restarts automatically
Check firmware version in device menu
Verify PUSH/ADMS feature is enabled
Remove USB drive safely

Step 5: Configure Server

Access device network settings
Enter BioTime server IP address
Set server port (default: 4370)
Enable PUSH communication

Step 6: Test Connection

Device should appear in BioTime
Test user synchronization
Verify attendance data transmission
Check real-time connection status

Common Issues & Solutions

Firmware update failed or device not responding

Solutions:

Verify you're using the correct firmware file for your exact device model
Format USB drive to FAT32 (not exFAT or NTFS)
Try a different USB drive (some devices are picky about USB compatibility)
Ensure firmware file is in the root directory, not in a folder
Check if you're holding the correct button during power-on (consult device manual)

Device not connecting to BioTime after firmware update

Checklist:

Verify device and server are on the same network (or VPN is configured)
Confirm server IP address is correctly entered in device
Check firewall rules allow port 4370 (BioTime default)
Ensure PUSH feature is enabled in device settings
Restart both device and BioTime service

How long does firmware update take?

Typically 2-5 minutes depending on device model. Do not power off or remove USB during update. LED indicators will show progress (usually blinking patterns). Device will restart automatically when complete.

Can I rollback to previous firmware version?

Yes, you can downgrade firmware by following the same USB update process but using an older firmware file. However, this may cause data loss. Always backup device data before firmware changes.

Will user data be erased during firmware update?

Usually NO — firmware updates preserve user data (fingerprints, faces, records). However, it's best practice to backup data via BioTime before updating firmware, especially for major version upgrades.
