Olympus IX-81 VISA Read Problem

[StressedGradStudent]

Hello All,

I am having the same problem and did the changes mentioned in this post, but they didn't work. IX2-BSW program is working and I tracked the serial commands being written and read. An example is:

write:

32 50 4F 53 3F 0D 0A

2POS?..

read: 

32 50 4F 53 20 33 35 30 30 30 0D 0A

2POS 35000..

However,

1.NI Max test panel gives Read problem error from the test panel

2. Olympus Command VI gives read error as well, when I enter a command (actually the same command with the first message of this topic: 

2POS?\r\n

Since I am new to Labview, I tried everything I found on internet:

1. I changed the COM port settings as in this link and checked from msdos-->MODE if they are really changed:

https://micro-manager.org/wiki/Olympus

Or specifically:

Baud rate: 19200, data bits:8, parity:even, stop bits:2, flow control: RTS/CTS

2. I increased and decreased the timeout time, did not work

3. I am doing everything after restarting the computer again, to be sure.

4. I changed the command string's display property to backslash first, did not work,(which is the same write code written above), I checked it from the serial port monitor:

 31 32 50 4F 53 3F 5C 72 5C 6E 

12POS?\r\n

 It basically adds '`1' or '`31` in hexadecimal, this is coming from the Device number input in the program. Device no is concatenated to the message

5. .Then I changed the command string's display property to hexadecimal, the same thing happened, a '`1` is added

The device number string is going to two concatenation objects. It (reasonably) adds 0 to the message when I make it 0. It gives error when I remove this from the block diagram, because concatenation wants another input.

What do you suggest me to do? Since there are other inputs to the object, I don't want to change it.  I am assuming there is something I might be missing, any help is appreciated, I attached thescreenshot.

Hi StressedGradStudent,

When you query the device in MAX VISA Test Panels are you sending what the device expects according to the User Manual for the microscope?

Also, I would strongly recommend creating a new thread to increase traffic looking at your issue rather than adding on to a solved thread.
