3. Configurations.

3.1 Tu'o lahi

There are three frequency bands to be selected

——800MHz/1.4GHz/2.4GHz. You can choose the

suitable frequency band according to local regulations.

The specific frequencies for each band are as follow:

800MHz：806~825MHz；

1.4GHz：1427~1447MHz；

2.4GHz：2408~2480MHz；

3.2 'Initaneti (bandwidth)

There are four BW to be selected——3MHz/

5MHz/10MHz/20MHz. The greater the BW, the more

data can be transmitted, but the weaker the

kaunoa ʻa e fili. In Fixed frequency mode, M50/M51 will have

more frequency to fix with small BW.

Additional, there is a shortcut key on M50/M51.

You can change BW easily. While NB is narrow band，

and WB is wide band. For both the air and ground unit,

the shortcut key should in the same place. Me'a kehe, they can not link.

3.3 Malohi 'o e RF

M50/M51 has three levels of power to choose.

In order to cause interference between devices, Kataki 'o

select the appropriate transmission power. The specific

RF power values are as follow：

1-Maʻulalo：15dBm；

2-Mid：20dBm；

3-Maʻolunga：25dBm。

3.4 Hopping/Fixed Mode

There are two mode to be selected——Hopping

/Fakaleleiʻi. In Hopping mode, M51 can automatically adjust

frequency when there is interference. In fixed mode,

the device is fixed to a special frequency . So in one

tuʻo lahi ʻa e tameʻa, up to four sets of devices can be used.

3.5 Encryption

The wireless signal can be encrypted during transmission.

When enable this function, you can set your private password.

The password should in the range of 100000~999999. Devices with different password do not link. When disable this function, different M51 air and ground can link each other.

3.6 Working Mode

M51 can work in Point to Point Mode and Repeater

Founga. Only the air unit of M51 need to be set. The ground

unit can synchronize automatically. In Repeater mode, ʻa e

air unit can be set to TX (IR Transmitter) or Repeater.

                                    

With Repeater mode, M51 can be easily used under NLOS situation. You only need to buy one more air unit and then can establish a repeater system easily.

M51 Web UI Configuration Description
