Page 5: Introduction
AT command set Introduction This document provides a detailed specification and a comprehensive listing for the whole set of AT commands for the ARM Cortex M7 Series serial to Ethernet converter. This document applies to USR-N510,USR-N520,USR-N540,USR-N580 models. 2. AT Command Setting Approach 2.1. - Page 6 AT command set Check Auto Append Bytes Figure 2 Send AT command Figure 3 Now you can send AT command to the module.If no command is sent within 30 seconds, the module will automatically exit the Network AT command mode.

Page 7: Serial At Command Mode
AT command set 2.2. Serial AT command mode After the device is powered on and starts working, you can send commands through the serial port to set device parameters. The syntax and usage of the AT command are described in details later. The default parameters of the serial port are as follows: Baud rate 115200, None Parity bit, 8 Data bits, 1 Stop bit. -
Page 8: At Command Error Code
AT command set 3. After receiving ‘a’, the USR module sends ‘+ok’to the device or tool and enters the AT instruction mode 4. After receiving ‘+ok’, the device or tool knows that the USR module has entered AT instruction mode and can send AT commands to it. -
