Have you verified the baud rate of 4800?

Hi James,

I have Verified the Baud rate with 4800 with this step :

DATA_EVENT[dvLVP603]
{
      online:
      {
            send_command dvLVP603,"'SET BAUD 4800,N,8,1,485 disable
      }
      String:
      {
           send_string 0,"'the LVP603 says --> ',data.text"
      }
}

for verify the notification from AMX, I was use telnet and notification in netlinx

from telnet :

send_command dvLVP603,"'GET BAUD'"

and I received :

LVP603 says --> baud 4800,none,8,1,485 disable

note:
If I took baud 4800 and I send any command I have no feed back if I send any command
if I took above baud 38400 and I send any command I have feedback from device FF FF FF FF FF FF
if I took baud 115200 and I send any command I have feedback from device FF FF a2trdj}FF DF

so anyone can solve this problem please share with me

The protocol does not mention a carriage return ($0D), try not removing it.

For example:

send_string dvLVP603,'zzmkxxxxxy';

Also, for code examples, please use the code tags as it makes it much easier to read.
[$code] <-- remove dollar symbol
Some code
[/code]

Hi James,

Unfortunately, until now I can't control that equipment
I have already moved "$0D" and try all baud rate but I don't have any result
