RE: asyn connetion to wti

[Mark Rivers via Tech-talk <tech-talk at aps.anl.gov>]

Hi Hawi,

 

Sorry, I was not being clear.

 

Please disable the StreamDevice debugging.

 

Please add the following lines to your startup script, right after the drvAsynIPPortConfigure line:

 

asynTraceTraceIOMask(PORT, 0, ESCAPE)

asynSetTraceMask(PORT, 0, ERROR|DRIVER)

 

where you replace PORT with the name of the asyn port you created. I think it might be LS325_IP.

 

Then restart the IOC and send all of the output.

 

Mark

Subject: asyn connetion to wti

 

Dear All, 

 

I am trying to connect a softIOC using asyn and StreamDevice to a wti console server, which has a serial connection to a LakeShore325.

 

I am able to telnet to the wti and communicate with the LakeShore. I am also able to connect the softIOC to other devices and send messages.

 

There seems to be some issue between asyn and the wti, which is serving a standard telnet connection.

 

The protocol file is:

ExtraInput = Ignore;
ReplyTimeout = 2000;
Terminator = CR LF;

getID {
out "*IDN?";
        in "%s";
@init {out "*IDN?"; in "%s";}
}

 

Below is a log snippet from asyn. It seems to read the following data then timeout:

<ff>?<18><ff>?

 

 

Any help would be greatly appreciated. 

Thank you,

Hawi
