【What is the product model?】: serial device server USR-TCP232-302
【What's the firmware version?(You can get firmware version from AT command AT+VER or settings webpage)】:4018
【How do you connect and configure the USR device?】: Operate via LAN, TCP client
【What's your application? What do you want to realize?】: I want to connect to the module from my computer using LAN. I want the module to pass through serial commands like I was sending to an RS232 port.
I have a device which accepts commands by RS232. I want to send the commands over LAN.
It seems like the module menu and settings can be reached using the module ModuleStaticIP.
I have configured the module for our LAN and given it a static IP which I can use in a browser and see the status. The web page for the module claims no data is being sent but I am sure that it is.
Here are 3 screen shots.
1. 302 config
2. My object that is trying to connect to the module
3.shot of the module's web interface
