FEIG LRU1002 RFID阅读器通过LAN连接电脑的故障排查求助

Hey there, let’s work through getting your FEIG LRU1002 RFID reader connected over LAN to your computer using ISO start 2017. I’ve helped troubleshoot similar FEIG setups before, so here’s a step-by-step guide to diagnose and fix the connection issue:

Basic Pre-Checks #

• First, confirm physical connections: Make sure the Ethernet cable is securely plugged into both the reader’s LAN port and your computer/router. Try swapping the cable with a known-good one to rule out a faulty cable.
• Check the reader’s power: Ensure the LRU1002 is properly powered on—you should see the status LEDs lit up (refer to your manual for which LEDs indicate active power and LAN connectivity; a steady green LAN LED usually means the network link is active).

LAN Configuration Verification #

• Check IP alignment: The LRU1002 comes with a default static IP (typically 192.168.0.100, but double-check your manual for the exact value). Make sure your computer is on the same subnet as the reader. For example, if the reader uses 192.168.0.100, set your PC’s LAN IP to 192.168.0.x (where x is between 1-99 or 101-254 to avoid IP conflicts).
• Test network reachability: Open your command prompt (Windows) or terminal (Mac/Linux) and run ping [reader's IP address] (replace with your reader’s actual IP). If you get consistent replies, your LAN connection is working at the network level. If not, check if your router is blocking traffic between your PC and the reader, or if the reader’s LAN port is faulty.

ISO start 2017 Setup Walkthrough #

• Launch ISO start 2017 and head to the Connection Settings (usually under a "Settings" or "Device Configuration" menu).
• Select LAN/Ethernet as the connection type from the dropdown.
• Enter the reader’s IP address and the correct port number—FEIG readers commonly use port 2000 for TCP connections (verify this in your LRU1002 manual to be 100% sure).
• Click "Connect" or "Test Connection". If it fails, try switching between TCP and UDP modes in the software; some FEIG models have a preference for one protocol over the other.

Advanced Troubleshooting Steps #

• Factory reset the reader: If you suspect misconfigured IP settings on the reader, perform a factory reset (follow your manual’s instructions—this usually involves holding a physical reset button for 5-10 seconds). This will revert it to the default IP, making it easier to re-establish a connection.
• Check firewall interference: Temporarily disable your PC’s firewall (or add an exception for ISO start 2017 and the reader’s IP/port) to rule out firewall blocking the connection.
• Update reader firmware: Outdated firmware can cause compatibility issues with ISO start 2017. If you can connect the reader via USB first, check FEIG’s official documentation for the latest firmware for the LRU1002, update it over USB, then try the LAN connection again.
