Default ASTM Client Receiver

I want to create an ASTM Client Receiver so that we can connect a Siemens DCA Vantage Analyzer to Mirth. I would like to start with the existing LLP Listener but don't know where to go to tweak it so that it will behave well with an ASTM sending Client. Any ideas on how to go about doing this?

I'm also interested in this - any ideas?

Sorry guys, I'm not too familiar with ASTM, that's just another specialized protocol right? Assuming it resides at the TCP payload level, you could certainly just set up a TCP Listener (probably in binary mode assuming the datagram is bit-packed) and then use a filter/transformer to parse out all the relevant fields and do whatever you want. Then, you can also choose to respond from a custom destination, and then return a custom-built ASTM response.

Again, I don't know a lot about ASTM, but unless it's very similar to LLP, the TCP connectors would probably be easier to work with.

An ASTM Listener/Sender is currently on the roadmap. In the meantime, you can use the TCP or LLP Listeners as narupley suggests, but you'll have to handle the start/end of transmission characters in the stream.

Default What roadmap



I can't seem to find any roadmap or anything in JIRA about ASTM being on the implementation route. The only ASTM i see, is a closed issue in JIRA.

We're currently working on it; barring any unforeseen circumstances it will be included in the 3.0 beta release at the end of the year.

Always include what Mirth Connect version you're working with. Also include (if applicable) the code you're using and full stacktraces for errors (use CODE tags). Posting your entire channel is helpful as well; make sure to scrub any PHI/passwords first.

Default 0x01{Astm payload}0x04

receiving a non 1381 astm package, ex. 0x01{Astm payload}0x04, is easily done with the tcp receiver, set it to delimitted text, and set the message template to an astm message (1394) should be about it.

Following untested:
DCAvantage as far as i know packages the entire 1394 message in a 1381 frame (which is a misunderstanded implementation usage of 1381, at least i believe so) but fortunately (atleast i think so) it should be manageble in mirth, when receiving. The only problem seems to be that it is hard to send a ACK back to the device.

Anywho, I currently implementing a astm connector in mirth and is pretty close to having a testable version, it will support delimitted 1394 messages (like 0x01{Astm payload}0x04) and the 1381 lowlevel. I have tried to contact mirth to hear if they would be interested in the source or not, but i got redirected to their contribution page, which wants me to read and sign some document. Which i will do, when they have told me wheter or not they want the code... anywho..

hope it helps a bit

You're right - placing a 1394 message in a simple "1381" frame like <ENQ>Message<EOT> is technically not ASTM 1381; it's just a regular TCP transmission with start/end characters (much like basic MLLP). We're also working on ASTM functionality, both the 1394 (HL7-like) data type and the 1381 lower-layer protocol (including the semi-complex back and forth acknowledgements/timeouts/contentions). Custom frame-encoded TCP payloads will also be included, so that something like "<Start Bytes><Actual Message><End Bytes>" will be very easily to implement.

Also just FYI, the aforementioned functionality will be included in 3.0, which is substantially different code-wise from 2.2.1. So any patches/additions to the 2.x branch won't be entirely applicable to 3.0. That said, we're always willing to accept contributions, so go ahead and send it in! If you wish, you can also post your code and ideas on the Development forum for all to see. Thanks!

Thanks for the update on your roadmap intensions.

I am working on 2.2.1.

In regards to connector development, i got a couple "questions" related to 3.0:

I have encapsulated the protocol code in the a protocol class where input output interface are streams, i guess your not changing the receiver/dispatcher concept in the connectors?.. wheter it is backed by mule or not shouldn't make much of a difference, atleast i think.

UI is completely like the existing connectors, so there shouldn't much problem, unless your changing away from netbeans UI?

regards
Niels
