Connect Your Sysmex XN-550 to Any HIS or LIMS

The Sysmex XN-550 is a mid-volume automated haematology analyser delivering a 5-part differential CBC. It is widely deployed in hospital labs across Asia, Africa, and the Middle East.

Connect your XN-550 to any HIS or LIMS. LISBridge reads the ASTM E1394 stream off the RS-232 port, parses WBC, RBC, HGB, HCT, MCV, MCH, MCHC, PLT, and differential counts, validates each result, and forwards to your HIS automatically — eliminating manual transcription.

How LISBridge Connects the Sysmex XN-550

01

Connect your instrument

Plug in via RS-232 or point it at LISBridge over TCP/IP. Auto-detection identifies the instrument and loads the correct parser — no manual selection.

02

Parse the data

LISBridge reads the ASTM E1394 stream in real time. Every result message is decoded — field by field — into structured data.

03

Validate results

Each result is checked for completeness. Duplicates caught. Malformed messages flagged. Only clean data moves forward.

04

HIS receives clean data

Validated results reach your HIS automatically — as HL7 or direct format. Stored locally too. No manual entry required.

Sysmex XN-550 — Frequently Asked Questions

What protocol does the Sysmex XN-550 use?

The Sysmex XN-550 communicates via ASTM E1394 over RS-232 serial. LISBridge implements the full ENQ/ACK/EOT handshake and parses all H/P/O/R/L record types produced by the XN-550.

Does LISBridge support the Sysmex XN-550 bidirectionally?

LISBridge receives results from the XN-550 (host-push mode) and can optionally receive query responses in host-query mode if your HIS sends HL7 ORM work orders to LISBridge.

How long does setup take for the Sysmex XN-550?

Typically under 30 minutes. Plug in the RS-232 cable, open LISBridge, and the XN-550 is detected automatically. The correct ASTM parser loads without manual selection.

Does LISBridge work if the internet goes down?

Yes. LISBridge is offline-capable. Once activated, it runs on your local machine — no internet required. Results continue flowing to your HIS during outages.
