The parameter configuration board on the transmitter and receiver is optional.
Yes, the frequency can be changed from 170Mhz to 860Mhz.
The frequency should be modified to the same on the transmitter and receiver. Of cause, the Power Amplifier and antenna frequency should modify the same frequency. (You need to buy a power amplifier and antenna for the transmitter and receiver to meet your changed frequency).
The default frequency is 590Mhz, With 30Mhz (+/-15Mhz), you can change it without modifying the Power Amplifier and antenna. For example, 578Mhz, 584Mhz, 590Mhz, 596Mhz, and 602Mhz.
Yes, it supports to send the video and UART data from the transmitter and receiver.
As it is one-way transmission, so it can not send the control command from the receiver to the transmitter.
If you need to send control commands or other data from the receiver to control other devices such as cameras or drones at the transmitter, you can add a set of cheap digital transmission equipment, contact us, and we can customize it for you.
Please check the UART define on the transmitter and receiver at the below link. Please tell me if you want to have a lead cable. (default is no)
The transmitter default Power Amplifier is 2 Watts, so it can support 30 KM at line-of-sight.
The below picture is our tested distance from the mountain to the seaside.
If you want to transmit a longer range, you can increase the power amplifier. In addition to one watt and two watts, we can also make 5 watts, 10 watts, and 20 watts for your choice. Larger amplifiers also require larger batteries and current support.
Our engineer can change frequency to 300Mhz from default 590Mhz, The antenna and PA in the warehouse are 590Mhz, 300Mhz need two weeks for customize, so the delivery time needs longer than our default 590Mhz.
Step 1: Please press OK and the right button at the same time, a menu of whether to save appears on the screen.
Step 2: Please press OK to choose Yes to save.
Remind, please use the bigger or longer antenna if your project allows, it can get better reception performance in the larger range.
