Hallo everyone,
i have a big problem in communicating with my LA-100 syring pump(it is a german brand,but almost same like other syring pump). I use a USB/RS232 conventor and RS232/RJ11 to connect the computer and the pump. I build a very typical VISA structure, but it doesn't work.
(Baud rate is 9600)
1. " A triangle appears in the upper left corner of the LCD display after the pump has receivedvalid communications " according to this from manual, it should work, because i see the triangle. But when i send 0DIA<cr>, 0 means adress of the pump, DIA means diameter of the syring, <cr> is the termination character. In the read buffer , i get 0DIA back, without any error, that really confuses me. I also send other command, just nothing happens, no error, and always give the same commando back, which i sended.
2. In manual 10.2.2, i see the Command syntax to pump is : <command data ><CR> , command syntax from pump is: <STX><response data><ETX>, i don't know, if hier can any problem appears in my VI. (from 10 begin the RS232 communication in manual)
I also asked the manufactory, they means it should be right with my VI and send me again the same manual , which i already have........
I struggle against this problem for already one week, i have read in NI community maybe more than 100 posts about syring pump, but can't find someone, who has same problem like me.
I would really appreciate it, if anyone can help me.
