DATEYE

AL550 Optical Biometer

The Topcon AL550 is an optical biometer with a built-in HTTP API. DATEYE integrates with the AL550 in two distinct directions: importing biometry measurements from the device, and exporting client registration data back to the device. Each direction is configured as a separate connection in DATEYE.

Overview

Import (AL550 → DATEYE): DATEYE periodically polls the AL550’s built-in HTTP API and retrieves new biometry measurements. The AL550 stores complete biometry data including axial length, keratometry, corneal thickness, pupil diameter, and signal quality metrics.

Export (DATEYE → AL550): When a new patient needs to be measured on the AL550, DATEYE can push the client’s demographics (name, date of birth, gender) to the AL550’s patient registration endpoint. This pre-populates the patient on the device before the measurement begins.

The import and export connections to the AL550 are configured separately in DATEYE. Both connection cards must show green for full bidirectional integration.

Import: AL550 → DATEYE

Prerequisites

  • The AL550 and the computer running DATEYE must be on the same local network.
  • The AL550’s network access and HTTP API must be enabled. Refer to the AL550 operator manual for instructions on enabling network connectivity.
  • Note the AL550’s IP address from the device’s network settings screen.

Configuration

Host / IP AddressAL550’s IP address on the local network192.168.1.50
PortAL550 HTTP API port (default: 8080)8080

Step-by-Step Walkthrough

  1. Open DATEYE and navigate to the Connections screen.
  2. Click the + button to add a new connection.
  3. Select AL550 Import from the device list.
  4. Enter the AL550’s IP address in the Host / IP Address field.
  5. Enter the port number (default: 8080) in the Port field.
  6. Click Save to create the connection.
  7. Perform a test measurement on the AL550.

DATEYE will poll the AL550 automatically. The connection card turns green once the first successful connection is established.

Verification

Expected result: The AL550 import connection card shows green. After performing a measurement on the AL550, the result appears in the DATEYE History screen within the polling interval.

If the connection card shows an error:

  • Confirm the AL550 is powered on and connected to the network.
  • Verify the IP address matches what is shown on the AL550’s network settings screen.
  • Check that no firewall on the DATEYE computer blocks outbound connections to the AL550’s port.

Export: DATEYE → AL550

Prerequisites

  • The same network requirements as the import connection apply.
  • Client demographics (first name, last name, date of birth, gender) must be stored in DATEYE for the clients you want to register on the AL550.

Step-by-Step Walkthrough

  1. Open DATEYE and navigate to the Connections screen.
  2. Click the + button to add a new connection.
  3. Select AL550 Export from the device list.
  4. Enter the AL550’s IP address and port (same values as the import connection).
  5. Click Save to create the export connection.
  6. Select a client in DATEYE and trigger a client registration export to verify the connection.

Verification

Expected result: The AL550 export connection card shows green. After triggering a client registration, the patient appears in the AL550’s patient list.

If registration does not appear on the AL550:

  • Confirm the AL550 export connection card shows green (not the import card).
  • Check that the client record in DATEYE has a name and date of birth — these fields are required by the AL550.
  • Review the DATEYE History screen for any export error entries.
