Setting IP on PMT Access Control Hardware
Proper network configuration is one of the most important steps when deploying or servicing access control hardware. Whether installing a new controller or troubleshooting communication issues, assigning the correct IP address ensures reliable communication between devices, servers, and management software.
This guide explains how to configure an IP address on PMT access control hardware and outlines several important considerations before connecting devices to a production network.
Why Proper IP Configuration Matters
Modern access control systems rely on network communication for:
- Event and transaction reporting
- Credential validation
- Remote management
- System monitoring
- Firmware updates
- Integration with third-party systems
Improper IP configuration can result in communication failures, offline devices, delayed transactions, and increased troubleshooting time.
Before You Begin
Before assigning network settings:
- Confirm the controller is powered correctly
- Verify physical network connectivity
- Ensure the desired IP address is available
- Record the required:
- IP Address
- Subnet Mask
- Gateway
- Ensure the configuration workstation can communicate with the device if direct connection is required
Documenting assigned network information is recommended for future maintenance and troubleshooting.
Configuring IP Address
Ensure your PC’s Ethernet adapter (Local Area Connection) is configured with an IP address in the same range as the unit’s factory default IP address (192.168.100.1). For example, set the PC to 192.168.100.xx.
Perform a factory reset on the unit:
- On the center bank of DIP switches, set Switch 1 to the ON position.
- Power cycle the unit.
- After the unit powers up, wait approximately 60 seconds.
- Set Switch 1 back to OFF.
This process restores the unit’s default IP address to 192.168.100.1.
Connect your PC directly to the unit and use Command Prompt to ping the factory default IP address. Confirm that the unit responds successfully before continuing.
Open the Discovery Utility and connect to the unit. Double-click the detected device to open the Configuration dialog box.
- Default password:
masterkey - For 400i units, the password is
impro
Without modifying any existing IP information, enable Static mode by checking the three boxes beside:
- IP Address
- Subnet Mask
- Gateway
Do not change any IP values at this stage.
Select Update.
Run the Discovery Utility again to rediscover the unit. A green check mark should now appear in the Static column.
- If the green check mark does not appear, repeat the process starting from Step 1.
Double-click the unit again to reopen the Configuration dialog box. Verify that all three Static check boxes remain enabled.
You can now change the:
- IP Address
- Subnet Mask
- Gateway
Enable the Force Update checkbox, then select Update.
Best Practices for Access Control Networking
Reliable network infrastructure plays a major role in overall access control system performance.
Recommended practices include:
- Using static IP assignments
- Keeping detailed network documentation
- Standardizing controller naming conventions
- Segmenting security devices using VLANs when appropriate
- Monitoring device communication health
- Restricting unnecessary network access
These practices can improve reliability, simplify maintenance, and reduce downtime across larger or multi-site deployments.
Common Network Issues
Several common networking problems can affect access control hardware communication:
- Duplicate IP addresses
- Incorrect subnet masks
- Invalid gateway settings
- Firewall restrictions
- Misconfigured switches
- Unstable PoE delivery
- Network segmentation conflicts
Carefully validating network settings during installation can help prevent future communication problems.
