Lakeshore 331 Temperature Controller Remote Communication with MATLAB
显示 更早的评论
I am trying to communicate with a Lakeshore 331 Temperature Controller via RS-232 serial interface. I would like to query the instrument's identification information and current temperature reading. I am using the following code, but the output comes back jarbled:
lakeshore331 = visa('ni','ASRL3::INSTR');
set(lakeshore331,'InputBufferSize',3000000,'Timeout',5.0);
fopen(lakeshore331);
iden = query(lakeshore331,'*IDN?')
temp = query(lakeshore331,'KRDG?')
fclose(lakeshore331);
delete(lakeshore331);
clear('lakeshore331');
Here's the output that results:
iden =
LÓCI,ÍOÄEL³³1E,³°¶°¶1,°³2³°1
Š
temp =
«7¹®¹¹8
Š
Do you have any suggestions for how to clean up the output?

Probably 3 years too late, but....
lakeshore331.DataBits = 7
lakeshore331.Parity = 'odd'

It worked with me while using RS232 serial communication Visual Basic .NET .
Thank You very much
