BT3000 Plus / Chameleon Bi-Directional LIS Interfacing Guide
Complete engineering specification, HL7/ASTM protocols, pinouts, and parameter mapping for BT3000 Plus / Chameleon on AILS Cloud LIMS.
1. Instrument Overview & Interfacing Architecture
The BT3000 Plus / Chameleon is a high-performance biochemistry instrument designed for diagnostic laboratories and hospital health networks. Integrating this analyzer directly with AILS Cloud LIMS eliminates manual transcription delays, prevents typographical patient identification errors, and automatically enforces Westgard delta check algorithms.
AILS automatically generates worklist queries (QRY^Q02 / ASTM orders) mapped to patient accession barcodes and pushes test instructions directly to the instrument sample tray.
Raw OBX / Result records are parsed instantly within 200 milliseconds, flagged for abnormal reference ranges, and linked to pathologist digital signature queues.

| Instrument Code | LOINC Code | Clinical Parameter Name | Standard Units | Default Reference Range |
|---|---|---|---|---|
| GLU | 2345-7 | Glucose | mg/dL | 70.0 - 100.0 |
| CHOL | 2093-3 | Total Cholesterol | mg/dL | 140.0 - 200.0 |
5. Biomedical Engineering Tips & Common Gotchas
In BT3000 Plus settings, configure Host Interface to ASTM E1394 format.
AILS Gateway decodes ASTM record blocks between STX and ETX and sends ACK.
Verify that sample carousel position IDs match accession records in LIMS.
Frequently Asked Questions: BT3000 Plus / Chameleon Interfacing
Common biomedical engineering questions regarding connection, worklist setup, and data capture with AILS Cloud LIMS.
Q: What interface protocol does BT3000 Plus use?
BT3000 Plus uses ASTM E1394 protocol over TCP/IP socket (Port 5001) or RS-232 serial.
Q: Can BT3000 Plus operate in bi-directional mode?
Yes. Sample tube barcodes scanned on the sample wheel are queried against AILS LIMS.
Q: What serial cable is required for BT3000 Plus?
A standard DB9 Null Modem serial cable (Pin 2-Rx, Pin 3-Tx, Pin 5-GND) running at 9600 baud.
Q: How does AILS handle QC runs on BT3000 Plus?
Control runs are routed to AILS Levey-Jennings QC module for automated multi-rule validation.
Q: What throughput is supported on BT3000 Plus?
BT3000 Plus processes up to 300 tests per hour in random access mode.
