EBME Forums Forums Maintenance Technical Assistance Communication with Alaris/Asena Syringe Pump

Geoff - For others, yes, I used a CRC-CCIT funtion on the SYRFORCE part of the command.

I'm pretty sure that the 80AD part is a CRC-CCIT of the rest of the command. In the same way that you have to do a CRC of the command you send, the pump does a CRC of the data it sends back.

To be clear, I did not use Hex characters. I just sent '!SYRFORCE|1E6F' to the pump. But yes, using a different terminal program to the one I normally use was what fixed it in the end.

RoJo - Fair enough, that's a valid concern. Probably shouldn't say this, but you do know that you can easily download the technician manual from various sites? Also the code has previously been mentioned on the thread.

Hello Folks,
Nice to hear that some ppl in UK are trying to access the communication port on the Infusion pumps. Currently I am on a clinical research project for Closed Controls with Large Volume Infusion pumps as well as Syringe pumps.

I am trying to communicate using the RS232 port on the following PUMPS:

Alaris Medical - Medley, Medley PC, Gemini

Smith Medical( formerly Medex) - Medfusion 3500

Problem in US is that we have to use FDA approved pumps. So the Alaris Asena wont work in the US.

I would appreciate if anyone has the data communication protocol documentation for both devices, which will be really helpful for us.

Any c/c++ SOURCE CODE..pls let me know.

Cheers
Tim

Only an infra-red serial interface on the Medfusion 3500?

How does the Medley system communicate?

IEEE 1073 is (will be) the answer to all this ... it just seems to be taking "for ever" to get off the ground!

Hello Geoff,
The old Model of Medley communicates via the RS232 9 pint port situated on the back of the device.
Lol..First I thought IEEE 11073 was the answer to our ailing issues. Now another standard IEEE 1073? How many varieties of standard are we going to prod into?
I thought IHE would be helpful, but IEEE 11073 is a nightmare to understand and its like a jigsaw puzzle.

yes indeed protocol converters and parsers.

By the way which medical device manufacturer has decided to opt for IEEE 1073?

Cheers
Tim

Looks like Siemens Medical is the only one implementing IEEE 1073 (MIB.

Cheers

They make the chips so might have a vested interest.
It was a good idea but needs everyone on board for it to work.

And Dräger?

It would be interesting to have some detailed technical information about all that; cable pin-outs and such.

Philips patient monitors generally come with many connection options as well. The MIB (P-1073) is usually picked off an 8-pin RJ45 "RS-232" connector. Yes; how messy is that?

Hello Geoff,
The Philips IntelliVue Monitor MPXX and MX700/800 can provide data acces to the LAN as well as Serial RJ45-RS232 ports connectivity.

However if both port are accessed simultaneously. In such scenario only the LAN port will provide both numerical and waveform data.

The cable pin-outs are described in the data communication documentation. It goes into detail how to set it up etc.

Well IEEE 1073 was a great idea but most device manufacturers sort of had a lack of interest for some odd reason that I am not sure why.

I wish the IEEE 11073 was more simpler to understand i.e. Like the DICOM standard.I think philips was the only one to implement IEEE 11073 but not completely.
