I've been working through a tutorial* with few modifications. So far no problems until I try to initiate communication with a Stanford Research Systems PS365 HV supply. When I run ./st.cmd, everything says it initializes, but then I get a message saying that the ioc did not receive a response within 1 second. The exact error(s) are:
CA.Client.Exception...............................................
I can "manually" communicate with the device using a simple screen command. I use the same port address with 9660/8/N/1 standard settings. It seems to take a second, maybe 2, to open the connection. So my thought was that maybe I just need to have the asyn driver increase its timeout time to avoid this error.
I can't see a way to change the timeout, however.
