Does anyone have experience with XTC/C OR XTC/2 controller?

I was wondering if you had any experience with sending ASCII commands. The manual for this Inficon device requires that commands sent terminate with the 'ACK ASCII command and I am a bit confused as to how I would be able to do this. Also on the read back, the data coming back ends also with the same termination 'ACK so would I need to accommodate that?

ACK is control F or hex 06. Set a string control or constant to Hex Display and enter the value 06 or set it to '\' Codes Display and enter \06. On the read, you can set VISA to terminate a read when the character is seen.

On the VISA Config serial port, the termination character is only a numerical input. How would I set it to a hex 06 value?

[Dennis_Knutson]

It's a hex numerical input. The default is xA or the \n or Line Feed. Just enter the value 6.

Sorry for post at the wrong place but i can't create a new subject (always print "please make a search before to post" and after do a search the same message print).

I actually work on programming a XTC/2 (film deposition controller) with labview, i success on communicate with it on RS232. i test many command but i don't find how to change active crystal,i explain :

 i need to get data of two single head crystal (one connect on sensor 1 and the other connect on sensor 2) without launching program on XTC/2, i have no problem to get data on one of them but i can't change active crystal to get data on the second single head (but i can change sensor in prog but no effect in active crystal always the same i get data).

The only way i found to change active crystal is to change sensor in program, start, wait, stop and reset but when i do this crystal active change and i saw on the XTC/2 screen "XTALSWTCH" and crystal active change at this moment.

What is the command (or the method) to do this change, without  start and stop the pro, with RS232 com? i test many thing but nothing work.

Thank for answer (you can move my message in a new subject if it necessary beacause i can't create a new subject)
