Hello Folks,
We are remotely interfacing with the Carefusion Alaris GH Plus Syringe Pump via the serial communication port.

The Carefusion Alaris Plus GH syringe pump can be remote controlled via the RS232 communication port.
We have an Alaris Asena GH, it works fine with the communication protocol both in monitoring and controlling modes.

However for the Carefusion Alaris Plus, it does not work in the controlling mode.
Our findings are,
1. The Baud rate is 115200 but not as stated in the manual 38400, the baud rate 38400 is working for Alaris Asena GH. Can someone please confirm what the true and actual Baud rate is?

2. The remote monitoring for Carefusion Alaris Plus, the result is list below, it worked fine.

3. But in remote Controlling operation we observed some problems,
In Asena Alaris GH pump, it worked fine and we can control the pump , set the infusion rate, start the pump.

But for the Carefusion Alaris Plus GH Pump, we had the following responses.

The Pump did not reply for the remote commands, INF_VI_CLEAR, INF_RATE^ 0.0^ml/h, INF_START and etc, such that it was not possible to make the pump infuse.

As it replied in the Step 2, !REMOTE_CTRL^ENABLED^****^PERMIT^0^ms|7BB0, we assumed that the pump can be remotely controlled and it was enabled. It replied for the command in Step 3 but not the others later.

At the end , it replied correctly with the remote mode disabled.
Please can anyone confirm if there any commands needed to further enable those un-replied commands and whether the CareFusion Alaris Plus GH can be remote controlled or not , at all.

I would really appreciate you help in this urgent matter.

Although I believe (hope) that you are a "DIY" guy, Tim ... there seems to be a lot of this stuff going on now:-

1) CareAware
2) DataCaptor
3) Device Link
4) SmartLinx

... to cite but four! smile
