Software operation Instructions

Support 5M, 10এম, and 20M bandwidth, real-time graphical interface display, real-time map indication, ইত্যাদি.

The software disables DHCP by default, and the default IP address is 192.168.17.1 If you forget the address, please connect the 9th pin of the 26PIN cable to the ground to reset the parameters.

Enter the IP address of the module in the browser, and the default username and password are both admin. It takes about 20s for the module to connect to the network from power-on. The recommended browser is Chrome.

After entering, it defaults to simple mode, click expert mode to unlock more settings, suitable for professional debugging.

Status section:

ওভারভিউ:

Topology map: (automatic refresh is turned off by default to save bandwidth, you can check automatic refresh)

Check only the display path, you can know the direct jump point relationship of each module

Check the details to judge the data connection status of each module. These are displayed dynamically in real time

Click Details: You can know the specific situation of each module directly:

Terminal state:

Ad hoc network: You can remark the name, of course, it can also be operated in the terminal state.

Spectrum scanning: Check the interference of each frequency band. অবশ্যই, the frequency bands of different modules are purchased, and the scanning frequency bands are different.

Map: (অবশ্যই, to know the location information of each terminal, GNSS modules such as GPS or Beidou need to be installed)

Support tile maps, image maps, network maps, ইত্যাদি.

Configuration section

মোড: 1. MESH node or bridge configuration

2. Wireless configuration:

2.1 Transmission power configuration, the power of different products purchased is different.

Channel bandwidth: 5M 10M 20M 40M

চ্যানেল: Different channels are used to purchase different products

The coverage distance (মিটার) needs to be filled in according to the actual situation. If it is set to 3000 মিটার, it is impossible to actually run to 5000 মিটার.

Number of Antennas 2

Fixed MCS rate: Can be set to off for automatic selection. If you want stable transmission, it is recommended to set the manual, পরিসীমা (MCS0 to MCS15)

From MCS0 to MCS7, two wireless ports send the same data in order to improve stability during the movement.

From MCS8 to MCS15, the two wireless ports send different data, which can make the rate X2

If it is in a mobile state, it is recommended to use BPSK or QPSK to transmit data. 16QAM and 64QAM are suitable for use with fixed transmission.

If MCS8 to MCS15 is used, it is recommended that the antennas of the two ports be 90 degrees from each other, উদাহরণস্বরূপ, one is vertical and the other is horizontal.

If drones are used, MCS0 to MCS2 is recommended.

The greater the bandwidth, the lower the sensitivity. The same goes for modulation.
