programation rs232

[marc_lip59]

Bonjour à tous,

à l'aide d'une communication rs232 et de labview, j'aimerais activer la ligne de transmission Txd du rs232, c'est à dire avoir 5v en sortie.

J'ai réussi à activer les lignes Dtr et Rts en utilisant un noeud de propriété, mais je ne trouve pas le noeud pour TXD.

Lorsque j'utilise les fonction "write" et "read", je reçois bien ce que j'écris mais mon niveau est de zéro volt.

Comment puis je faire ?

D'avance merci

Translation

using communication and rs232 labview, I activate the transmission line of Txd rs232, ie have 5V output.

I managed to activate the DTR and RTS lines using a node property, but I can not find the node to TXD.

When I use the function "write" and "read", I get exactly what I write but my level is zero volts.

You cannot "activate" the transmission line.  That is the line that ouputs your data.  It is going to be a bit stream of 0's and 1's that is based on the data that you send out by way of the VISA Write function along with start bits, stop bits, and parity bits.
