Hi,Everybody,I got a problem of communication with SR73A and 74A Series Digital Controller.

I have been made a connenction with the SR73A, I can read the data of the SR73A, but when I write the command and data into SR73A, I got error message like this."@01ER 09:0C",that means "Value is out of prescribed data range in the case of write command".so someone ever do this instrument's driver can tell me how to fix this problem? or give me some hint ,thx a lot

Hi skywalker,

Have you checked the manual of the device to see yet if the level you are trying to set it at is within range? I have not used this instrument or this instrument driver, but perhaps we could dig into the driver and see where this error is set, and see why it could occur within the program. Then you could see if it would be a problem to simply ignore the error or not.

I solve this problem.
The reason is it can not recognize the right format of number.
e.g.
When you write the number format of "20" which followed the manual says, it will sent back to you error:"ER09".that means out of range.
You will format 20 like this "+00020", but you should format it like this "+0020.0". I don't konw why? maybe someone could tell me the detail.
thx
