 WE-D485-4G is a 5-mode all-network 4GDTU that supports mobile, Unicom 2G/3G/4G, and Telecom 4G networks (Telecom 3G is not supported), and the network supports a maximum downstream rate of 150Mbps and a maximum upstream rate of 50Mbps, so it can work well in remote areas that lack 3G and 4G network coverage (mobile, Unicom).
WE-D485-4G has built-in rich network protocols and integrated RS485 standard data transmission interface, which does not require any driver and is convenient for traditional serial devices to be used in networking. It can meet almost all M2M requirements, including automotive and personal tracking services, wireless POS, smart metering, industrial-grade PDA, bike sharing, car sharing and other M2M applications.The detailed specifications of WE-D485-4G series in terms of network protocols are shown in the table below, and the red color is the commonly used models in China.

Internal structure:

Mounting method:

RS485 have lead wires are A (data +) and B (data -), and equipment RS485 connection A (+) connected to the A (+), B (-) connected to the B (-), interference in the case of a serious proposal to connect GND together.
This product can take 32 terminal 485 devices. The maximum communication distance is 1200 m. The 485 termination resistor is 120 ohms, which is usually necessary when wiring over 300 meters. Note that when wiring, A+ and B- must be a pair of twisted pairs to minimize signal interference.

Areas of application:

The WE-D485-4G module connects serial devices to the Internet and transfers serial data in compliance with the TCP/IP protocol.
