Selectra ProS Bi-Directional LIS Interfacing Guide
Complete engineering specification, HL7/ASTM protocols, pinouts, and parameter mapping for Selectra ProS on AILS Cloud LIMS.
1. Instrument Overview & Interfacing Architecture
The Selectra ProS 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.

4. Parameter & LOINC Standard Code Mapping
| Instrument Code | LOINC Code | Clinical Parameter Name | Standard Units | Default Reference Range |
|---|---|---|---|---|
| GLU | 2345-7 | Glucose Fasting | mg/dL | 70.0 - 100.0 |
| CHOL | 2093-3 | Total Cholesterol | mg/dL | 140.0 - 200.0 |
5. Biomedical Engineering Tips & Common Gotchas
Configure Selectra ProS to communicate via TCP port 5002 in Host Settings.
Check that reagent barcoded bottles are scanned before launching analytical runs.
Ensure AILS Gateway is configured with matching STX/ETX framing.
Frequently Asked Questions: Selectra ProS Interfacing
Common biomedical engineering questions regarding connection, worklist setup, and data capture with AILS Cloud LIMS.
Q: What interface protocols are supported by Selectra ProS?
Selectra ProS supports ASTM E1381/E1394 over TCP/IP socket (Port 5002) and RS-232 serial.
Q: How does Selectra ProS transmit biochemistry test batches?
Results are transmitted in real time as ASTM record frames as each photometric reading completes.
Q: Can Selectra ProS operate with bi-directional worklists?
Yes. Sample barcodes scanned on the rotor are queried against AILS LIMS to fetch test profiles.
Q: How are ISE module parameters mapped on Selectra ProS?
Sodium, Potassium, and Chloride values are mapped to dedicated LOINC codes in AILS LIMS.
Q: What baud rate is used for Selectra ProS serial connections?
Standard baud rate is 9600 bps, 8 data bits, no parity, 1 stop bit.
