Hi!

Good day everyone.

Sorry I am so new in using Node-RED this is because one of my client is using Node-REd ever since but unfortunately we have challenges on sending commands into Code Reader Device (specifically OMRON F430 Series) via TCP connection.

for reference this will be the commands I am trying to send:

JOBLOAD  
Loads a job from slot n or from memory.

Command Format  
JOBLOAD -slot=SettingValue -r  
or  
JOBLOAD -mem -r  
• Specify -slot or -mem.  
• Insert a space between the command and the parameters.  
• Insert a space between each parameter.  
• Add a delimiter to the end of the command or parameter.  
• No space is required between the parameter and the delimiter.

[https://www.fa.omron.com.cn/data\_pdf/mnu/z444-e-02\_f430-f\_f420-f.pdf?id=3789](https://www.fa.omron.com.cn/data_pdf/mnu/z444-e-02_f430-f_f420-f.pdf?id=3789)

Almost all of the commands did not work for me except the TRIGGER Command.  
This trigger command send a trigger to the F430 for sensor capture.

All of the commands already tested via hyper terminal and it all works fine.

I am now thinking what was missing on my sample nodes.

Hope somebody can help me. Thanks in advance!

Do you maybe need to add a `\n` or `\r` character to the end of the command as an [enter] to get it to send correctly ?

Hi,  
I actually have the sensor so I made a few tries. This is working for me.

Let me know.
