Hi all,

I've been working to get an IOC up and running for a lakeshore 331 TC we have here at NSLS2, using the support for it I found in the ip module on github: https://github.com/epics-modules/ip/blob/master/ipApp/Db/LakeShore331.db

To start, I have the IOC just creating the asyn port pointing at the TCP Server on the appropriate port on the moxa, and I load the asynRecord database, so I can test sending/receiving commands using the asynOctet interface. I configured the serial connection on the moxa, asyn, and the device to 9600 baud, 8 data bits, and one stop bit, and I can see that I am communicating with the device on some level, however, the responses I am seeing don't seem correct; they are full for unexpected characters, and don't match the format listed in the manual. I am guessing there is still something I missed in the configuration of the serial connection.

Current IOC startup:

Also, while every command I send gets some (different) response, I seem to get a timeout error for the asynOctet interface, indicating something is not quite right:

Has someone configured such a device that has run into a similar issue? Or alternatively, does anyone know what could the cause be?

Thanks for the help!
