Sysmex CA-660 LIS & EHR Connection

Quick answer

Yes. The CA-660 specification lists a bidirectional RS-232C host connection using ASTM or the Sysmex CA-1000 protocol. A serial device server carries that port onto your network, where the Catenix gateway exchanges messages with the analyser and updates the EHR or LIS. Protocol choice and serial settings are confirmed on your unit during setup.

The Sysmex CA-660 is a compact coagulation analyser, about 57 cm wide, aimed at low-volume laboratories and at larger labs that want a backup instrument. Within the CA-600 series it is the model that adds chromogenic and immunologic channels to clotting, which brings antithrombin, protein C, anti-Xa heparin and D-dimer onto the same bench as PT, APTT and fibrinogen.

Samples go on a single continuous-access rack of ten primary tubes or cups, with one priority position for urgent work. It manages roughly 60 PT tests an hour, or 32 an hour when PT, APTT, fibrinogen and D-dimer are run together.

What	How Catenix handles it
Detection channels	4 clotting (660 nm), 1 chromogenic (405 nm), 1 immunologic (575 nm)
Rack	10 tubes or cups, continuous access, plus 1 STAT position
Throughput	PT about 60 tests/hour; PT, APTT, Fbg and D-dimer about 32/hour
Host port	Bidirectional RS-232C
Host protocol	ASTM or CA-1000 protocol
On-board QC	X-control and Levey-Jennings, 6 files of 180 points per parameter
Stored data	600 samples, 3,000 patient results

A serial-only analyser on a modern network

The CA-660 specification lists no network socket for the LIS: the host connection is an RS-232C serial port. Catenix bridges it with a serial device server placed beside the analyser. If the network drops, the gateway reconnects and carries on.

Of the two protocols the specification offers, ASTM is the one Catenix uses. Each message is stored with its result, and the analyser's own memory of 600 samples gives a second place to look if something needs resending.

Two-way traffic on the CA-660 host port

Because the port is bidirectional, test requests can travel down to the analyser as well as results coming back. How your unit collects its requests, and whether it uses the tube barcode to do so, depends on its configuration and reader, and is checked during setup.

Results return matched by sample ID. A PT or D-dimer with no matching order waits for review. The optional hand-held 2D reader is for reagent, calibrator and control lot data, not for the LIS link.

Small-lab coagulation QC

The CA-660 keeps Levey-Jennings files on board, six per parameter. When control results are transmitted to the host, Catenix files them as QC alongside your other analysers, applies Westgard grading and holds patient results for a parameter whose control has failed. During an internet outage results stay on site and are forwarded afterwards.

Questions people ask

Does the Sysmex CA-660 have an Ethernet port for the LIS?

Its specification lists the host connection as a bidirectional RS-232C serial port. A serial device server puts that port on the network.

Is the CA-660 host interface one-way or two-way?

Two-way. The specification describes the RS-232C host connection as bidirectional, using ASTM or the CA-1000 protocol.

Which CA-660 tests can be sent to the EHR?

Any test the analyser reports, from PT, APTT and fibrinogen to antithrombin and D-dimer. Each test code is mapped to your EHR's code during setup.
