* SNR IN: There are five columns of data, which stands for five antenna's peformance,these numbers must over 24 value.
Net Weight 0.232kg per unit (No antenna included) 0.512kg per unit (No antenna included)
The larger the value, the better the performance. If one(s) of them under 24,then the Antenna(s) looss or the Antenna/SMA connectors
Temperature 0 ~ 40 °C (operation), -20~60 °C (stock)
broken probably.
*Specifications are subject to change without notice.
* SNR OUT: There are two columns of data,the last two columns stands for the performance of Transmmiter'santenna.
The value must over 15.The larger the value,the better the performance.
* PIN: There are five columns of data,which stands for the numbers of lost packets when machine work on, the valus must under 60.
Follow the following solves :
The bigger the value, the more complete the data transmission.
● Please check the power supply of transmitter and receiver first. If power is supplied by battery or external power supply,
● Please ensure that the battery or external power supply is energized and output normally.
* AUDIO BER:There is one column of data, which stands for Audio Packet Loss.Reference value is 0. The larger the value,
● Please check whether the antenna connected to the transmitter and receiver is firmly installed.
the more packet loss the audio will be.
● please check whether the video output format of the camera is compatible with this product.
● Please check if the battery is too low.
● Make sure that transmitters and receivers are placed at least 1.5 meters above the ground.
● If the problem still can not be solved, please contact your supplier.
