Erba XL-640 / EM-360 / Chem 5 Bi-Directional LIS Interfacing Guide
Complete engineering specification, HL7/ASTM protocols, pinouts, and parameter mapping for Erba XL-640 / EM-360 / Chem 5 on AILS Cloud LIMS.
1. Erba XL-640 / EM-360 / Chem 5 Interfacing Overview & Diagnostic Workflow
The Erba XL-640 / EM-360 / Chem 5 is a high-performance clinical chemistry analyzer dedicated to routine photometric assays, enzymatic kinetics, and ion-selective electrode (ISE) electrolytes. Connecting the Erba XL-640 / EM-360 / Chem 5 to AILS Cloud LIMS establishes a closed-loop analytical cycle—automating test profile assignment, monitoring serum index flags (Hemolysis, Icterus, Lipemia), and preventing reporting errors across high-volume chemistry workloads.
Photometric absorbance calculations and ISE potential readings transmitted by the Erba XL-640 / EM-360 / Chem 5 are ingested in real time, converting raw analyzer voltage/OD readings into calibrated clinical concentrations.
AILS automatically reads HIL (Hemolysis, Icterus, Lipemia) interferent flags emitted by the Erba XL-640 / EM-360 / Chem 5, warning technologists when sample integrity compromises photometric accuracy and logging auto-dilution rerun factors.

Frequently Asked Questions: Erba XL-640 / EM-360 / Chem 5 LIS Interfacing
Common biomedical engineering questions regarding connection, worklist setup, and data capture with AILS Cloud LIMS.
Q: What communication protocol does Erba XL-640 use?
Erba XL-640 uses ASTM E1394 standard protocol over RS-232 serial port or TCP/IP socket.
Q: Can semi-automated Erba Chem 5 Plus analyzers connect to AILS LIMS?
Yes. Erba Chem 5 Plus outputs formatted serial ASCII strings over its RS-232 printer port, which AILS captures automatically.
Q: What serial cable is required for Erba XL-640 and EM-360?
A standard DB9 Null Modem Cable (Pin 2-Rx, Pin 3-Tx, Pin 5-GND) running at 9600 baud.
Q: Does Erba XL-640 support bi-directional worklist queries?
Yes. When sample tube barcodes are scanned on the sample wheel, test panels are fetched from AILS LIMS.
Q: How does AILS handle calibration curves for Erba chemistry analyzers?
Multi-point calibration curves and daily QC runs are tracked in AILS Levey-Jennings QC module.
