1. Pls use LAN0 directly if you only use RJ45 connector,the system will discern WAN/LAN port automatically.
2. LAN0 and Lan4 are LAN port under 3g router mode and AP mode if you want to us 2 RJ45 ports, LAN4 is WAN port, LAN0 is LAN port under standard router mode .
3. The software of one RJ45 connector and two RJ45 connectors is different . Pls contact us to get related software version.
4. UART1 is the connector for data transmission, UART2 is internal adjusting connector.No open for customer use .
M350 USE 5.22mm height standard PCIE connector, See below sketch map for connector :
M350 have a WIFI antenna connector. Antenna impedance must choose 50 mm cable and antenna for characteristic impedance purpose. Antenna connector on module Which we use 51-3612-50-H from Astron company connector or U.FL-R-SMT-1(10)RF from HRS company connector (these two connectors are common use ) .The demision for RF connector listed as below :
3 Connector’s application
3.1 UART connector
Module support 2 UART connectors, Only UART1 open to the public, it can be used as connect user host’s UART,or serial equipment .It support data transparent transmission mode and order mode . UART2 is used ad internal adjusting.
3.2 Power supply connector
The standard voltage value we offer for external is 3.3V(3.25-3.335V). It can supply powe for module, The peak current is 1A.
3.3 USB bus
Module offer 1 high speed USB connector. It can be used as HOST or DEVICE,also can connect 3G module ,USB equipment ,storage euipment and so on .
3.4 LED State display
Module offer 5 state indicatior pin feet,power,SYS,3G dailing,LAN1,LAN2.It can be used for indicating state.
1. Power indicator: It will be bright when power supplied .
2. SYS indicator (SYS): It will be flashing when the system operated normally.Detailed state definition list below :
a) Single flash when it is in 3G router mode, use 0.1 second bright, 1 second dark.
b) Double flashing When it is in WAN router mode , use 0.1 second bright, 0.1 second dark,0.1 second bright, 1 second dark.
c) Third flashing when it is in WIFI router mode, use 0.1 second bright, 0.1 second dark,0.1 second bright, 0.1 second ,0.1 second bright, 1 second dark.
d) Overdue for 3G fee mode( flashing continuous)
3. 3G state indicator( connect Internet state indicator) 3G dailing successfully or It will be bright when connect successfullhy.
4. LAN light: It will be bright when successfully connected, It will be flashing when data pass through.
3.5 GPIO connector
1, SYS system light:GPO11
2, 3G state light( Connecting internet light): GPIO12, it flashes when dailing, resigned IP will be bright.
3,Watch dog’s signal: GPIO14, it will send 100ms high levels per 30 seconds.( It will have this function for V220.127.116.11 and above upgrading software )
4, Reset function : GPIO0, high levels sometimes, Low levels when keep on 5 seconds, the system will restore to the defaulted value.
5, TF card core chip control: GPIO13
6, RS485 core chip reversible control: GPIO17
7, Switched control when it’s in router mode:GPIO18, it wil be switch to 3G/WIFI/LAN router mode when you pull lower one time .
8, Control online or offline when IO control : GPIO19(JTAG_TMS)
3.6 Serial Port Instructions:
1, Version 18.104.22.168 offer serial port service function and keeping upgrading and innovating .
2, Open up the setting page of wireless router for 192.168.10.1, Open “server”,Choose “com2server” to set what you need to .
3, Serial service can be devided into order mode and serial transparent transmission mode
a)Serial order mode:Send some orders to wireless router by serial port,we can obtain current time,current web type, current internet total data, current 3G/4G signal strength related information, detailed order can refer to serial port order table.
b)Serial port transparent mode : you can set the ip address and port of server you want to connect,Make 3G/4G router connected with the pointed TCP or UDP server, establish transparent data transmission channel ,realize the data transparent transmission.
C)If set serial service function open when it’s power off, then it’s on serial transparent mode and connect automatically pointed server when it’s power on .
d) If set setial service function closed when it’s power off, then it’s on serial order mode and receive serial mode directly when it’s power on.
e)You just need to sending “+++”if want to back to serial order mode from serial transparent mode. You just need to “ATO” if you want to back to transparent mode from serial port oder mode.
4,Serial transparent mode can be devided into customer end mode and server mode ,
a) Customber end mode is normal use mode, it can connect remote server automatically when power on and can establish transparent data channel .
b) Server mode is detective mode , waiting for customber end connnection.
Only the assigned IP from China telecom is visible IP in public network and it can be used as server. The assigned IP from China mobile communication and China unicom are inside network IP. External network can’t access to, So it can’t be used as server.
c)If you want to be used as a server, it can also use DDNS function. Namely is that fasten a fixed DN with assigned IP casually ,customer end only need to connect this fixed domain name and no worry the IP address frequency.There are many providing DDNS service supplier so far,such as “Oray”,“3322” and so on , Only need apply for related information (such as DN,user name, password) to service supplier and fill in the 3G/4G router setting. 3G/4G router can connect suppliers accordingly and automatically and complete fixed dormain name .
5, If serial function is closed (transparent serial port function closed) ,then the serial port order can come into use.
1.You need to consider radiating when use M350 module for design development. High temperature can lead to efficient and stability loss. We suggest you adhering a larger radiating pin on main core chip.
2.The design principle of single LAN port and double LAN port is different .So upgradting version softwares are different.
3.You need to consider using melt adhesive for fastening the connecting card of antenna and the IPX deck to protect loosening if use module in a shaking environment.
4.M350 use standard PCI-E connector, Pls pay attention to 2 specifications connectors in general ,one is 4mm height,one is 5.2 mm height, M350 should use 5.2 mm .
4 Development board for external use
