Step 6) Set Cell SIM2. Follow Step 6 of setting Cell SIM1.

Step 7) Activate the “Cell SIM Switching Trigger” feature

Setting location: H750 web: Internet Settings – WAN — All Cell Option

There are 6 types of Cell Option Mode (Cell Switching Mode),

Mode Description
cell1 only With this mode, only sim1 works
cell2 only With this mode, only sim2 works
fail switch cell1 first With this mode, it works as below,
sim1 on – switch to sim2 on if sim1 failed, and keep working on sim2 – switch to sim1 on if sim2 failed, and keep working on sim1 –switch to sim2 on if sim1 failed, and keep working on sim2 – “cycling”
fail switch cell2 first With this mode, it works as below,
sim2 on – switch to sim1 on if sim2 failed, and keep working on sim1 – switch to sim2 on if sim1 failed, and keep working on sim2 –switch to sim1 on if sim2 failed, and keep working on sim1 – “cycling”
cell1 prefer With this mode, it works as below,
sim1 on – keep working on sim1 – if sim1 failed, switch to sim2 – keep working on sim2 for “Check Time (for Prefer mode)”, then try to check if sim1 is restored, if restored, switch to sim1 – “cycling”
cell2 prefer With this mode, it works as below,
sim2 on – keep working on sim2 – if sim1 failed, switch to sim1 – keep working on sim1 for “Check Time (for Prefer mode)”, then try to check if sim2 is restored, if restored, switch to sim2 – “cycling”
advance data traffic cell1 first With this mode, it works as below,
sim1 and sim2 have data limits. Sim1 on — once sim1 data count reaches the limitation, switch to sim2 — once sim2 data count reaches the limitation, sim1 and sim2 neither works until next day/week/month.With this mode, users need set the “Advance Cell Traffic” configuration
advance data traffic cell2 first With this mode, it works as below,
sim1 and sim2 have data limits. Sim2 on — once sim2 data count reaches the limitation, switch to sim1 — once sim1 data count reaches the limitation, sim1 and sim2 neither works until next day/week/month.With this mode, users need set the “Advance Cell Traffic” configuration. Refer to the detailed manuals from E-Lins.
cell on time traffic Sim1 and sim2 work according the time period schedule settings.

With this mode, users need set the “Advance Cell Traffic” configuration. Refer to the detailed manuals from E-Lins.

Notes: Sometimes it may happen the following,
1) Choosing ” fail switch cell1 first” or “cell1 prefer”, SIM2 is firstly online, this is not problem because sometimes the SIM1 has some problem to be online.

2) Choosing ” fail switch cell2 first” or “cell2 prefer”, SIM1 is firstly online, this is not problem because sometimes the SIM2 has some problem to be online.

Check Time (for Prefer mode): set the time for “cell1 prefer mode” or “cell2 prefer mode”

Description for Check Time (for Prefer mode):
For example1, Cell Option Mode is “cell1 prefer”, and Check Time (for Prefer mode) is “5” minutes. It works as below,
Router works with sim1 firstly — if sim1 failed, switch to sim2 — keep working on sim2 with 5 minutes — after 5 minutes, check if sim1 is ok, if ok, switch back to sim1.

For example2, Cell Option Mode is “cell2 prefer”, and Check Time (for Prefer mode) is “5” minutes. It works as below,
Router works with sim2 firstly — if sim2 failed, switch to sim1 — keep working on sim1 with 5 minutes — after 5 minutes, check if sim2 is ok, if ok, switch back to sim1.

Step 8) Click “View” button to double check if the settings are correct.

Step 9) Click “Apply” button or Re-power the router to reboot. Then H750 router will reboot and dialup online.

Once it’s online, the CELL LED will light on.
Notes: sometimes the router cannot dialup after the APN configuration, please power off the router, and re-power on it. Because some radio modules need reboot after the initial APN configuration.

Step 10) Once H750 router is online, it gets a WAN IP Address and Status Page will show similar info.

Step 11) Activate the “Cell ICMP Check” feature

Setting location: H750 web: Internet Settings – Cell ICMP Check

Notes:

1) For router working with best stability, we highly suggest activate and use this feature.

With this feature, the Router will automatically detect its working status and fix the problem.

2) Please disable the “Ping from WAN Filter” if use ICMP check feature, otherwise it cannot work.

 

  • Active: tick it to enable ICMP check feature
  • Check method: fill in checking domain name or IP. Click HOST/IP check button to verify before using it.
  • Check interval time (sec): set the interval time of every check
  • Check Count: set the checking count number
  • Reboot Count Before Sleep: H750 Router will sleep to stop checking after failed with set times.
  • Sleep Time (min): H750 Router sleep timing before resume check.

 

Example with above picture:

H750 Router check “www.google.com” and “112.134.8.8”, it will check 3 times. After the previous check, it will do next check after 60 seconds. Totally it will check 3 times. If 3 times all failed, H750 Router will reboot. If reboots 3 times continuously, H750 Router goes to sleep to stop checking. The sleep time is 5 minutes. After 5 minutes, H750 Router resumes to cycle the checking.

 

High Gain Antenna–Yagi-Uda Antenna

Category : 产品文章, 伊林思产品FAQ, 其他

Today, we are talking about high gain antennas. Here I want to introduce a strong one. A Yagi–Uda antenna, commonly known as a Yagi antenna, is a directional antenna consisting of multiple parallel elements in a line, usually half-wave dipoles made of metal rods.

Yagi–Uda antennas consist of a single driven element connected to the transmitter or receiver with a transmission line, and additional “parasitic elements” which are not connected to the transmitter or receiver: a so-called reflector and one or more directors.

The Yagi–Uda antenna consists of a number of parallel thin rod elements in a line, usually half-wave long, typically supported on a perpendicular crossbar or “boom” along their centers. There is a single driven element driven in the center (consisting of two rods each connected to one side of the transmission line), and a variable number of parasitic elements, a single reflector on one side and optionally one or more directors on the other side. The parasitic elements are not electrically connected to the transmitter or receiver, and serve as passive radiators, reradiating the radio waves to modify the radiation pattern. Typical spacings between elements vary from about  110 to ¼ of a wavelength, depending on the specific design. The directors are slightly shorter than the driven element, while the reflector(s) are slightly longer. The radiation pattern is unidirectional, with the main lobe along the axis perpendicular to the elements in the plane of the elements, off the end with the directors.

It’s also a good choice for you when you use E-Lins routers in rural area. This antenna will gain better reception than standard antennas for routers.
