Heraeus Votsch HT 4010 Serial ASCII communication

[Aaabbb2020]

HI, 

I am trying to communicate with my environmental chamber : Heraeus Votsch HT 4010. 

I have the ASCII protocol for the communication. See attached. 

I have tried to send the example ASCII commands as given in the ASCII protocol (from Page 51). 

Although do not seem to receive the expected response from the chamber. 

I have tried sending each command using Labview & also a terminal program (RealTerm). See attached VI & screen shots.

I am connection to the chamber via 25 d-sub to 9 d-sub cable to a 9 d-sub to USB to my laptop.

Do you know the difference between "<CR>" in "normal" string display format and "\r" in \-code display format?

Do you know the meaning of the CR string constant found in the string functions palette?

It seems you need to learn ASCII basics and how to handle/express "non-printable" control characters:
