* The device is an industrial 4G data terminal (DTU) that relays RS485 data over an LTE CAT4 network.<br />
* It is intended for the regions EMEA, Korea, Thailand, India and Southeast Asia.<br />
* Mounting is via a DIN rail (Hutschienenmontage).<br />
* The wiki lists related products such as UART TO ETH, RS232/485 TO ETH, etc.<br />
* Configuration software tools are provided: SSCOM (serial terminal) and DTU-Config.<br />
* The device supports switching between SMS transparent transmission, network transparent transmission, and AT command mode.<br />
* Entry into temporary command mode follows a defined sequence of character strings.<br />

== Notes and version constraints ==<br />
* Entering temporary command mode requires precise timing: no data within 200 ms before sending "+++"; the response character 'a' must be sent within 3 seconds.<br />
* Version-specific steps and regional network coverage are not stated in the source text – please verify before deployment.<br />
* The specified target region (EMEA, Korea, Thailand, India, Southeast Asia) determines supported bands; local network availability must be confirmed separately.<br />
