Which localhost port does Startek FM220 RD Service use?

Startek ACPL RD Service for UIDAI Aadhaar binds to candidate ports between 11100 and 11105, with port 11200 commonly designated for HTTPS operations on 127.0.0.1 (localhost). Our online diagnostic tester automatically sweeps all candidate ports to discover your active Startek driver.

How do I resolve 'No ACPL RD Service found' on Startek FM220?

Check Windows Services (services.msc) to ensure 'ACPL FM220 Registered Device Service' is Running. Ensure the scanner is plugged into a high-power USB 2.0/3.0 port without extension hubs. If on HTTPS, accept the localhost certificate for port 11200 in your browser, then click 'Scan for multiport'.

How do I test my Startek FM220 scanner online?

Plug in your Startek FM220 or FM220U scanner. Click '1. Scan Multi Ports' to auto-detect the listening port. Once the status shows 'RD Service is ACTIVE', click 'Device Info' to inspect serial numbers or 'Test Device (Auth)' to execute a live fingerprint scan.

What is the difference between Startek FM220U L0 and L1 scanners?

The Startek FM220U L0 scanner performs cryptographic biometric template encryption using software drivers on the host computer. The newer Startek FM220U L1 scanner incorporates a dedicated hardware secure cryptoprocessor directly within the scanner body to sign and encrypt fingerprints on-chip.

How do I resolve Startek Error 700 or Capture Timeout?

Error 700 indicates that the fingerprint capture timed out before a valid print was detected. Clean the optical prism with a dry microfiber cloth, place your finger flat and firmly on the sensor when the red LED illuminates, and adjust the capture timeout if necessary.

Pre-Flight Diagnostic Checklist UIDAI COMPLIANT

STEP 1
ACPL Startek Service Running:
Open services.msc and verify that ACPL FM220 Registered Device Service is Running.
STEP 2
Ports 11200 / 11100-11105 Open:
Startek RD Service binds to port 11200 or loopback ports 11100-11105 on 127.0.0.1.
STEP 3
Direct High-Power USB:
Connect directly to a motherboard USB 2.0/3.0 port without passive USB splitters or extensions.
STEP 4
Clean Optical Prism:
Ensure the scanner glass is free of moisture, dust, and grease for optimal minutiae capture.

Frequently Asked Questions — Startek FM220 RD Service FAQ & Driver Help

The Startek ACPL RD Service driver commonly operates on port 11200 for secure HTTPS communication, while also listening on UIDAI candidate loopback ports 11100 through 11105 on 127.0.0.1. This tool scans all candidate ports simultaneously to locate your active service.

1. Open Windows Services (press Win + R, type services.msc), find ACPL FM220 Registered Device Service, and click Restart.
2. Unplug and reconnect the Startek FM220 scanner directly into a rear USB 2.0 or 3.0 motherboard port.
3. If using HTTPS, ensure your browser has accepted the local driver certificate for https://localhost:11200.
4. Click Scan for Multiport on this page to re-detect the port.

The Startek FM220U L0 performs biometric template encryption in host software drivers. In contrast, the Startek FM220U L1 features dedicated on-chip cryptographic hardware security that digitally signs and encrypts raw biometrics directly inside the scanner body, complying with UIDAI L1 mandatory guidelines.

Click Scan for Multiport until your Startek scanner is detected. Then click Test Device (Auth). The red LED sensor will illuminate. Place your finger firmly on the optical prism. Once captured, the tool displays your quality score (qScore) and confirms Aadhaar PID block generation.

Error 700 indicates a capture timeout—the biometric scanner did not detect a finger placed on the glass within the allotted timeout (default 20,000 milliseconds). Make sure the finger is clean, dry, and centered on the sensor before clicking capture.
