SI 440 detector with monochoromator

[YFA]

Hi I have a actonsp2300 monochoromator and SI-440 detector. I can use this monochoromator for scan wavelenght but i cant control detector. 

i am reading string inputs codes from detector. I used this monochoromator with lakeshore and keitley2400 but i need now use with detector. Any body can help me? I need read current or voltage from this detector.

Thanks.

Perhaps you are configuring it some place else but in the image you attached, I don't see any termination character being used. Check the manual and see what it is supposed to be

p.s. Wire up your error clusters and if the instrument sends a termination character, you don't need all of those VISA Bytes at Serial Port.

I dont used any therminal character my other programs too and them working. Because i think all default value current for this terminal.

 you don't need all of those VISA Bytes at Serial Port.

Does this make a problem?

Wire up your error clusters and if the instrument sends a termination character,

I was wired error cluster but instrumen dont send any error code. 

I am reading string from indicator .READ so i must read any current value from inducator. I think a overlock a prossess. But dont know yet.

Sory i forgot attachment manuel. Pdf is attached.

make a start with subvi's that write a command and read the answer but only read when either the endchar is available or enough characters are available.

With your write /read all chars now available you can easily read too fast and so read not all characters needed for the answer.

Please remeber that data on a serial line take time to get there.

I have no idea what 'my other programs too' are. Terminal emulation programs such as Hyperterminal/Procomm/etc. automatically send a termination character and it is something you have to program into LabVIEW.

You want to get error codes from the VISA functions.

You think its ok now? I am not trying  time is 00:36  now here

Its dont work 😞 someone can help me? why i cant read current.

Hard to debug a picture. Attach the actual VI or a snippet (look it up) but in order to actually send a control character, you have to right click on the string constant and select '/' Code Display. Did you do that? Did you verify with the vendor or a sniffer that a line feed is the termination character that you need?

Programs attached. Can u check pls 

Note: Version is 2010 if u wanna i can convert.
