•   DTU status : open and close DTU  
•   Baud rate : support 300/1200/4800/9600/19200/38400/57600/115200bps  
•   Link Type : Server link or Client link can be chosen in the DTU configure table. If using it as Server, 
we suggest you to use fixed IP  of the SIM card. 
•   Multiple -path Backup : the router can support 4 Server IP at most to meet the need for multiple-
path data backup.  
•   Heart Beat function:  You can define heart beat time and heat beat information. So that Server can 
use the heart beat informati on to identify DTU.

The Virtual Router Redundancy Protocol (VRRP) is designed to eliminate the single point of failure inherent 
in the static default routed environment. VRRP specifies an election protocol that dynamically assigns 
responsibility for a virtual router to one of the VRRP routers on a LAN. The VRRP that cont rols the IP 
addresses  associated with a virtual router is called the Master, and forwards packets sent to those IP 
addresses. W hen the Master becomes unavailable, a backup (called Slave) takes the place of the Master. 
VRRP provides a function similar to the proprietary protocols “Hot Standby Router Protocol (HSRP)” and “IP 
Standby Protocol (IPSTB)”. If the Master fails, the Backup begins to service traffic formerly handled by the  
						

							12 
 
Master. This switchover occurs in 3 to 10 seconds.  
•   VRRP Active : Check to enabl e VRRP 
•   VRRP ID : Enter the Group ID for this set of redundant routers.  
•   Priority:  (1 -255)In a VRRP group, the larger number is Master, the smaller is Slave(backup)  
•   Interval Time : VRRP Enter the Advertisement interval(sec onds) 
•   Password:  Enter the shared group  password, or leave blank for no password.   
•   Virtual IP ： All hosts in the LAN are using this IP as default gateway.

2 .2.1 2.2 Port Forwarding 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Port forwarding is the process that your router or firewall uses to sort the right kind of network data to the ri ght  
						

							15 
 
port. Computers and routers use ports as a way to organize network data. Different types of data, such as web 
sites, file downloads, and online games, are each assigned a port number. By using port forwarding, the router 
or firewall sends the correct data to the correct place.  
•   Virtual Server Settings : open and close Settings.  
•   IP address: fill the IP address of forwarding.   
•   Port Range : fill the Port of forwarding.

DMZ host IP Address: Please Enter the IP address of the computer which you want to set as DMZ host  
Note:  When DMZ host is set, the computer is completely exposed to the  external network, the firewall will not 
influence this host.

This function will detect the status of 3G by ping and complete the corresponding actions according to the ping 
result.  
 
•   Reboot When Network Error : Choose the box to start the net detection function.  
•   Check Method (PING): fill the server domain name or IP, and then click the Check button to detect if the 
fill-in is right.  
•   Check interval time ( second): the interval time between the first detection and the second detection is 
60- 86400 seconds.  
  
						

							17 
 
•   Check Count:  when ping detection arrives to default time, but still cannot access, then the router will 
reboot.  
•   Reboot Count before Sleep : when continuous reboot times arrive to default value, the router will enter 
sleeping mode. This setting is to prevent the router to reboot continuously when cannot ping access 
caused by service IP’s error.  
•   Sleep Time (minute ): here to set sleeping time. W hen arrives, the router will start Ping check again.  
   
  Note:  This function will be only valid only in 3G permanent on- line and dialing according to the setting time, 
other modes do not work. Firstly you must detect if the filled- in server domain name or IP is valid. 
 
  
Re boot when timeout 
 
 
 
 
 
 
 
 
 
 
Timer (minute): input any number from 60 to1440, the router will reboot when arrives  to default value.  
 
2.2 .13.3 Software upgrade  
 
Upgrade the firmware to obtain new  
functionality. It takes about 2 
minutes. Please don’t move t he 
router until it reboots automatically.  
 
 
2 .2 .13.4 Parameter Management  
 
 
 
Here you can make a backup of current 
settings  or restore previous settings of 
the router .   
Export settings: click ‘export’ to export 
configuration files and then select save 
path.   
Import settings:  click ‘browse’, select 
previous backup configuration files and 
then click ‘Import’. Then all the  previ ous 
settings will be recovered.  
Load Factory Defaults: click ‘Load 
Default’ then all settings will be restored 
to  factory settings. This is not 
recommended, in order to avoid the loss 
of important parameters.

Chapter 3  FAQ 
 
•  SIM Card Status shows “Not Ready”  
 
It means the SIM card is not found, you can   
take SIM card out, and insert it again.  
 
•   Signal Strength is normal, but can’t get WAN IP  
 
Check the APN  parameters in WAN settings.  
 
 
•   Can’t visit the router from remote side  
 
 
1) Make a ping to the WAN IP to check whether it is successful.   
 
2) We are using 80 as router’s default port, but some ISP block the 80 port, you can confirm with local ISP   
which ports are open, and change port to try.  
 
 
 
 
 
 
 
 
LAN fails  
 
  
						

							19 
 
1)  Check RJ45 cable, make sure it is correctly connected.  
 
2)  Make sure the PC and router are in same network segment.  
 
3)  Disable the PC network card, and re- enable it.  
4) Reset the router. Press Reset  button   
for several seconds, it will load to factory   
settings.  
 
 
 
 
 
 
 
 
Get WAN IP, but PC can’t access internet.  
 
 
 
1)   Check the DNS, you can make a ping to a normal IP (e.g. 8.8.8.8), if ping IP is ok, the question must be 
caused by DNS.   
2)   Make sure the SI M card support data service, you can try it in your cell phone.   
3)   Signal is too weak. Move antenna or change position to get better signal   
 
Port forwarding not working  
 
1)   Check with ISP which ports are open by them  
 
2) More than 1 router. The most common pr oblem we come across is people who are behind 2 or more routers 
and don’t realize it.  
  So here is a quick step by step.   
Step 1. Login into your Router  
        Step 2. Find the status page that shows the WAN/Internet IP address and write it down.   
        Step 3. Log   into the first router/modem now.  
        Step 4. Find the DMZ page  
        Step 5. Enter the IP you wrote down into the DMZ page and enable DMZ. Step 6. Save  and your done. 
 
Thankfully it is easy to get port forwarding if this is happening. W e sim ply tell the first router to send all incoming 
connections to the 2nd router where the port forwarding rules are.  
 
Serial port not working  
 
Problem (1): I can get heartbeat from client on the TCP Server, but PLC data can’t come Solution: check the baud 
rat e of router and PLC, make sure their parameter settings are same.  
Problem (2): I can’t get heartbeat and PLC data from client on the TCP Server. Solution: check the TCP server and 
port, make sure they are allowed to visit.
