Please send the entire output when your IOC starts up, including the asyn commands to create the serial port driver and configure the baud rate, etc.

Subject: Response Time

 

Hello,

 

I've been trying to connect to my machine by RS232.

I use streamDevice and Asyn Module.

 

When we send command "*IDN?", we expect to get "THERMO OK" from the machine. 

I try the same connection on TCP/IP. I used serial to ethernet converter and communicated with the machine. No problem occured. But when I eliminated the converter and directly connected to the PC on RS232 port, I got the following error when I send the command.

 

I guess the problem is about response time. How can I configure the response time? Or if it is not response time problem, how can I fix it?

ERROR:

"2013/08/19 16:23:15.340949 thermoConn IDN: No reply from device within 1000 ms"
