Here is where they come from.

Quick answer Many ZKTeco terminals default to IP 192.168.1.201, port 4370 and Comm Key 0 (no password). Your K40 Pro may be set differently by the supplier, so confirm on the device under Menu > Comm. **Buy your ZKTeco K40 from Qyvea**: Supplied and installed across Kenya.

These are common factory values, not a promise. Suppliers and previous users change them. **Figure 1.** Communication settings: IP address, port and Comm Key. ## Check yours on the K40 Pro 1. Press Menu and sign in as administrator. 2. Open Comm. and look under Ethernet for IP, mask and gateway. 3. Look for the Comm Key or connection password and the Device ID/Number. 4. The port is shown in the same area, or in the system information screen on some firmware. ## If the default IP does not match your network A device at 192.168.1.201 will not talk to a PC at 192.168.0.10, because the third number differs. Change the terminal to a free address in your own range. See [how to set the IP](https://qyvea.co.ke/zkteco-k40-pro-set-ip-address). ## About the Comm Key The Comm Key is a numeric password the software must supply before it can talk to the terminal. Set one if the terminal sits where others could reach it on the network. If you forget it, you can reset it from the device menu with administrator rights. A mismatch shows as a failed connection; see [Connect to Terminal failed](https://qyvea.co.ke/zkbio-time-net-connect-to-terminal-failed). ## Can I change port 4370? Yes, but then the software must use the new port, and any router or firewall rule must allow it. Most offices never need to change it. ## A typical scenario A Ruiru warehouse technician tried the default 192.168.1.201 on a network that ran on 10.0.0.x. Nothing replied. Reading the real address from the terminal's Comm. menu showed the supplier had already set 10.0.0.60, and the connection worked at once. *Illustrative example based on common cases, not a named customer.* ## Common mistakes - Assuming the defaults without checking the device menu. - Typing 4730 or 3470 instead of 4370. - Entering a password that does not match the terminal's Comm Key. - Changing the port on the device but not in the software. - Forgetting the Comm Key after setting one. ## Quick checklist 1. Check IP under Menu then Comm. 2. Confirm port (usually 4370) 3. Confirm Comm Key (0 means none) 4. Record all three 5. Use the same values in the software 6. Keep the record with the terminal ## Frequently asked questions What is the default password of a ZKTeco K40? The connection Comm Key is normally 0. Menu admin passwords are different and are set by whoever installed the terminal. See [forgot admin password](https://qyvea.co.ke/zkteco-forgot-admin-password). Why does 192.168.1.201 not answer? Your PC is probably on a different range, or the supplier changed the IP. Check the device menu and run ping. Is port 4370 TCP or UDP? The software connection uses TCP/IP on port 4370 in the standard setup. Can two terminals share port 4370? Yes, as long as they have different IP addresses.
