What are the main working modes of 4G DTU?

4G DTU is a key component of the integrated application system of the Internet of Things. It provides wireless data transmission service for users by using public wireless network, and builds a bridge between data collection and application.

The 4G DTU F2X 16 series has six working modes, as follows:

PROT: heartbeat packet adopts TCP protocol, data communication also adopts TCP protocol, and heartbeat packet and data communication use the same TCP connection, so it is necessary to configure the 8-digit device ID number and mobile phone number.

DCTCP: a communication protocol related to power supply, which is transmitted through TCP protocol.

DCUDP: a communication protocol related to power supply, which is transmitted through TCP protocol.

TRNS: The equipment works in normal GPRS modem mode. In this mode, IP modems can be used for SMS, CSD and dial-up Internet access.

SMSCLI:DTU is short message DTU, and the work data is sent to the bound mobile phone through short message, and at the same time, the content sent by the bound mobile phone is received, and the data is sent to the designated peripheral interface.

Smsser: As a short message DTU, DTU sends its work data to any designated mobile phone by short message, but it has requirements for the content to be sent and must be bound and sent according to the specified format. At the same time, the mobile phone can send data to the short message DTU, and the short message DTU will send the data to the designated peripheral interface.
