Q1:--- Mc is connected to PC using USB

Q : 2--- after sending all the commands in Solved: Re: sending multiple commands at once using visa write and visa read - Page 2 - NI Community this link i will get this is the final output.

Q3: there are 14 commands and each commands should be send to the Mc( each command has different output but now im just care about the last commands output and as image shows the output of last command). in case if i dont send all the commands then output will not update.(so this is fixed command string which id commands) 

q4: yes it always starts with 1A but last 4 values are changing.

• Read the µC responses line by line.
• Check for "1A" as first two chars.
• If found read the next 4 chars, else omit that line…

hi,

Can you tell me? how can i proceed further to select four char and eliminate other all the chars. (im using match pattern to compare strings with 1A so it is elimanating all the charathers after  1A)
