Biometric Integration Errors and How to Fix Them

Purpose

This article addresses technical integration errors that can prevent your biometric device from syncing with HRStop, even after configuration is complete. These issues are often related to network restrictions, incorrect server settings, or problems with utility-based sync.

Who Should Read This

IT/Admin teams handling firewall and network configurations
Biometric vendors providing technical support
Implementation teams troubleshooting after setup
HR/Admin users coordinating issue resolution with support

When to Use This

Your device is configured but still shows as disconnected in HRStop
Punches are not being received despite correct ADMS or utility setup
Sync worked earlier but has suddenly stopped
Utility is running but data is not appearing in the HRStop portal

Common Integration Errors and How to Fix Them

1. Port Block by Firewall or Antivirus

Symptom: Device is not connecting to the HRStop server
Fix:

Ensure Port 84 is open for outbound traffic
Whitelist Server IP: 65.20.79.19
Check antivirus or firewall rules on the local network

Validation:
Ask IT to run a telnet or firewall diagnostic on the device network

2. Incorrect ADMS Server Settings

Symptom: Device setup looks correct, but punches never arrive in HRStop
Fix:

Double-check:
- Server Mode = ADMS
- Server Address = 65.20.79.19
- Port = 84
- Enable Domain Name = OFF
- Enable Proxy Server = OFF

Validation:
Reboot the device. A connected device should show an 'e' or globe icon.

3. Duplicate or Conflicting IP Address

Symptom: Device is intermittently disconnecting
Fix:

Assign a static, unique IP address to the biometric device
Use ipconfig on a nearby computer to check for existing IPs

Validation:
Ping the biometric device IP from another system to confirm no conflict

4. Proxy Server or Domain Name Enabled

Symptom: Internet shows as connected, but device fails to sync
Fix:

In the device menu, ensure both:
- Enable Proxy Server = OFF
- Enable Domain Name = OFF

5. Utility Sync Not Working (DAT/SQL Setup)

Symptom: DAT file is placed, but nothing syncs
Fix:

Confirm that the HRStop utility is installed and running
Ensure the DAT file is saved in the correct configured folder
Check that antivirus/firewall is not blocking the utility

Validation:
Ask HRStop for utility log files or re-run a test file

6. Outdated Firmware or Unsupported Device

Symptom: Configuration looks correct, but nothing works
Fix:

Check with your vendor for a firmware update
Contact HRStop to confirm whether your model is supported

7. Enrollment ID Mismatch (Non-Sync Related but Critical)

Symptom: Data appears in HRStop but not against employees
Fix:

Confirm that the biometric user IDs match the employee enrollment numbers in HRStop

Screenshot of Biometric Service Status from HRStop

Summary

Biometric integration errors are typically caused by network blocks, incorrect ADMS settings, or utility-level failures. These issues often look similar to general device problems but require deeper checks at the firewall, IP, or sync layer.
