1
Connect the Device to Your Router
— Physical connection
Take a LAN cable (also called an ethernet cable) and connect one end to the ethernet port on the back of the eSSL X990 device and the other end to any available LAN port on your WiFi router.
✓ No WiFi needed — the LAN cable gives the device a direct, stable internet connection.
2
Find Your Router's Gateway IP Address
— Required before configuring the device
The Gateway IP is your router's address on the local network. The fingerprint device needs this to know where to send internet traffic. Every router has a different gateway IP, so you must look it up from a device already connected to your WiFi.
🖥️ How to find your Gateway IP
🍎 Mac
netstat -nr | grep default
Look for the first IPv4 line (e.g. 192.168.x.x). That is your gateway. Ignore lines with "fe80::" — those are IPv6.
🪟 Windows
ipconfig
Open Command Prompt, run the command, and look for "Default Gateway" under your network adapter.
📱 Android / iPhone
Go to Settings → WiFi → tap your network name → tap (i) or Details. Look for "Router" or "Gateway" — that IP is your gateway address.
💡 Tip: Common gateway IPs are 192.168.1.1, 192.168.0.1, or 192.168.29.1 — yours may be different. Always look it up.

Configure Ethernet Settings on the Device
— Menu → Comm → Ethernet
Use the keypad to navigate. Enter the values exactly as shown in the table below.
| Field |
Value to Enter |
Notes |
| IP Address |
192.168.X.201
Replace X with your network's number (e.g. if gateway is 192.168.29.1, use 192.168.29.201)
|
This is the device's fixed address on your local network |
| Subnet Mask |
255.255.255.0 |
Standard — do not change |
| Gateway |
Your Gateway IP
Enter the gateway IP you found in Step 2 (e.g. 192.168.29.1)
|
Must match your router exactly |
| DNS |
8.8.8.8 |
Google's DNS — allows device to find api.thegymzee.com |
| TCP COMM Port |
4370 |
Leave as default — do not change |
| DHCP |
OFF |
Must be OFF so the IP stays fixed |
📌 How to set the IP Address correctly: Look at your Gateway IP. If your gateway is 192.168.29.1, your device IP should be 192.168.29.201 — same first three numbers, just change the last number to 201. If your gateway is 192.168.1.1, use 192.168.1.201.
✅ Save the settings by pressing OK or the confirm button on the device before going to the next step.
4
Configure Cloud Server Settings
— Menu → Comm → Cloud Server
This tells the device which server to send data to. Enter the values exactly as shown below.
| Field |
Value to Enter |
Notes |
| Server Mode |
ADMS |
Select ADMS from the dropdown |
| Enable Domain Name |
ON |
Must be ON to enter a website address |
| Server Address |
api.thegymzee.com |
Gymzee's server — type exactly as shown |
| Enable Proxy Server |
OFF |
Leave OFF — no proxy needed |
✅ Save the settings by pressing OK or the confirm button before restarting.
5
Restart the Device
— Required to apply settings
Go to Menu → System → Reboot, or simply power the device off and back on. Wait 30–60 seconds for it to fully start up and connect.
✓ After restart, the device will automatically connect to Gymzee's server in the background.
6
Verify the Connection
— Confirm the device is online
🔗 Test connectivity in your browser
Open this URL (replace YOUR-SERIAL with your device serial number):
https://api.thegymzee.com/iclock/ping?SN=YOUR-SERIAL-NUMBER
You should see a response like this:
{"success": true, "sn_received": "YOUR-SERIAL", "server_time": "2026-04-20 15:13:07"}
📍 Your device serial number is printed on a label on the back of the eSSL X990, or found at Menu → System Info → Serial Number.
⚡
Static IP is important
Keep DHCP turned OFF on the device. If DHCP is ON, the device may get a different IP address after every restart, which can cause connectivity issues.
📡
Router must have internet
The fingerprint device uses your router's internet connection. If the router's internet goes down, the device will continue to allow/deny access using the last synced data until internet is restored.
🔒
Do not change the Server Address
The Server Address must always remain api.thegymzee.com. Changing it will disconnect the device from Gymzee and stop member sync.
🌐
Gateway must match your router
If you change your internet router, you may need to redo Step 2 and 3. The gateway IP is specific to each router.

Setup Complete — Your device is connected to Gymzee!
Once connected, Gymzee will automatically sync member data and membership validity dates to the device. Active members can enter, expired members will be denied access — all managed from your Gymzee dashboard.
