Frequency Band
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:
800MHz806~825MHz
1.4GHz1427~1447MHz
2.4GHz2408~2480MHz
Bandwidth
There are four BW to be selected——3MHz/ MHz/10MHz/20MHz.
The greater the BW, the more data can be transmitted, but the
weaker the anti-interference. In Fixed frequency mode, VDC-7/
VDC-15 will have more frequency to fix with small BW.
Additional, there is a shortcut key on VDC-7/VDC-15.
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. Otherwise, they can not link.
RF Power
VDC-7/VDC-15 has three levels of power to choose.
In order to cause interference between devices, please select
the appropriate transmission power. The specific RF power
values are as follow
1-Low 15dBm
2-Mid20dBm 3
-High25dBm
Hopping/Fixed Mode
There are two mode to be selected——Hopping/Fixed. In
Hopping mode, VDC-7/VDC-15 can automatically adjust
frequency when there is interference. In fixed mode, the device
is fixed to a special frequency . So in one frequency band, up to
four sets of devices can be used.
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 VDC-7/VDC-15 air and ground can link each other.
Working Mode
VDC-7/VDC-15 can work in Point to Point Mode and Repeater
Mode. Only the air unit of VDC-7/VDC-15 need to be set. The
ground unit can synchronize automatically. In Repeater mode,
theair unit can be set to TX (transmitter) or Repeater.
