Communication RS 232
« on: April 22, 2013, 03:19:17 AM »
Hello,
I would like to communicate via the RS 232 between FMD88-10 and a masflow that communicates RS-232.
I try to send a string of such "070304716271620E" then Carriage Return and Line Feed.
I configured the same way the two products are: 1 start bit, 8 data bits, no parity and 1 stop bit.

My program:

in FirstScan
SETPROTOCOL 1.10
SETBAUD 1, & H06

then:

PRINT # 1 "070304716271620E" &H0D; &H0A;
FOR I = 1 to 10000
A $ = INPUT $ (1)
NEXT

By sending the same through the hyperterminal with my PC running Windows XP it worked! Can you help me this is quite urgent.
thank you

If your goal is to send a message terminated by a carriage return and a linefeed you might want to change the print statement from:

    PRINT # 1 "070304716271620E" &H0D; &H0A;

to:

     PRINT #1 "070304716271620E\0D\0A";

Your program, as presented, can not be compiled.  It is missing a ";" .  If your program was corrected so that it would compile:

   PRINT #1 "070304716271620E"; &H0D; &H0A;

The output would be:

    "070304716271620E 13 10"

There would be no carriage return and no line feed.

Best regards,
