I'm trying to setup new TCP Driver device. The device is a RADWAG Scale and the documentation does provide information for setting up the device. One requirement is that each command be terminated with a "CR LF". I've setup the device as Character Based and set the Adv Prop Writeback Message Delimiter to "\r\n". My question is, can Message Delimiters be combined like this? My device connects properly and the tags show Good Quality. When I send a command to the scale, I don't get any response back and being remote from the site, I'm having difficulty troubleshooting this.
I appreciate any help that can be provided.
Yes.
Take a look at a Wireshark capture to verify.
I'm checking with IT to see if installing Wireshark is allowed. I'll be surprised if they say yes as this client is pretty tight about security, and doesn't like to have apps installed on their servers.
Let me ask a follow up question(s).
In the case of this device, that requires a carriage return AND line feed termination characters, as noted, I applied the value "\r\n" to the Writeback Message Delimiter.
Do I need to add these delimiters to the Message or Field Delimiter parameters of the driver configuration? If yes on the Field Delimiter param, should the Field Count be modified?
Just to note, I have tried numerous configurations and can't get any respone in the "Message" tag:
For writeback to work? no.
Because the device may also use that format when sending you messages... yes, if that's the case.
You would want character-based, message delimiter of "\r\n", no field stuff set up.
