RE: RE: RE: Re: IOC Connecting Problem

[Mark Rivers <rivers@cars.uchicago.edu>]

I cannot explain why it takes 7.5 seconds for the device to reply to "*IDN?" on port 5024 and why it never replies within 10 seconds on port 5025.

When you interactively send the "*IDN?" command with telnet on port 5024 does it respond quickly or does it also take 7.5 seconds?

What timeout are you using in your StreamDevice protocol file?

Note that the fact that the Agilent scope and the DG645 both use ports 5024 and 5025 is because those are defined as SCPI-telnet and SCPI-raw respectively.  But they may behave differently on the 2 devices.

Dear Mark,
Most of all, Thank you for your kind answer.
Here is your question and my answer.

Ø What happens if you simply connect to port 5024 with drvAsynIPPortConfigure? Do you get an error?

-> No, I don't have error. It works well. Just needed about 7 seconds more for connecting. I guess this section is different.

I hope to know that why it is different between 5024 and 5025.
Also, when I check the DG645, it is connected well with IOC via port 5024, 5025.

Ø   I used port 5024 (successful, but when it start, the telnet connection required)

What do you mean by “the telnet connection required”?  What happens if you simply connect to port 5024 with drvAsynIPPortConfigure?  Do you get an error?


Ø  and 5025(failed).

How does it fail?

If I understand correctly you are concerned about 2 things:


-          Using port 5024 works but you think it may have poorer performance because it is a “telnet” port?

-          Using port 5025 does not work?

Can you send the output when the IOC starts with these commands first when using port 5024 and then again when using port 5025

drvAsynIPPortConfigure(P1, 192.168.1.73:5024, 0, 0, 0)

Dear Mark,
First of all, I appreciate your kind Email. I didn't know about the synApps "delayGen" module. I am going to try to use it.

Yes, I am trying to connect an Agilent oscilloscope to IOC. A DG645 was just an example that I connected with IOC before.
I checked there are two parts of connection(port 5024, 5025) in the case of the DG645. also, There are two parts of connection(port 5024, 5025) in the case of the Agilent oscilloscope.
So, I have thought that this is similar. However, when I tried to connect the Agilent oscilloscope to IOC, I used port 5024(successful, but when it start, the telnet connection required) and 5025(failed).
In the case of delay generator, I have used port 5025 which was successful with nothing telnet connecting first.
I am not sure whether I express my opinion properly. Thank you so much to read my Email. If you have any confusing things, would you let me know?

Best Regards,
Pilkyu

I suspect the difference between the telnet port 5024 and the bare socket probably has to do with line terminators and perhaps other things that it does to make the telnet connection easier to use with an interactive terminal session.

I am confused what device you are actually trying to talk to. Earlier today you mentioned an Agilent oscilloscope, but now you are referring to the DG645 delay generator. Note that there is already an asyn driver for the DG645 in the synApps "delayGen" module.

Mark

Rod:
Thanks a lot. Your comment is very helpful.
I have thought that It is different between Telnet and TCP communication, because there are two kind of communication in case of delay generator.
I attached delay generator's manual(http://www.thinksrs.com/downloads/PDFs/Manuals/DG645m.pdf).
As you can see, there are difference in page 44, operation 30, Table 14: NET Menu Options for TCP/IP Configuration.
Could you let me know what is different between Bare socket interface(port 5025) and Telnet interface(port 5024)?
In my case, I have used only port 5025 for connecting IOC.
I hope you have a nice day.

Telnet is simply doing the same kinds of TCP communication that the IOC
asynPort does. The connection seen by the oscilloscope is the same for a
telnet session as it is for an EPICS asynPort connection. In telnet, you
send commands interactively. The IOC sends commands as part of the
program algorithm. The data transferred is the same, and the scope
doesn't see any difference.

The port number is part of the IP address used to make the TCP
connection, so that is why it must be correct in order for the
connection to succeed.

I don't quite understand your last question. If you don't want to use a
telnet-like connection between the scope and the IOC, then you will need
to use some other kind of interface. Perhaps your scope is equipped with
GPIB or serial ports. These work equally well from the standpoint of
compatibility with EPICS asyn + streamDevice support.

I hope this helps.
