FAQ for wireless video transmission

1. Ae, the frequency range can be changed from 170Mhz (pai from 220Mhz) to 860Mhz. So it can work well at 260Mhz band.
2. Me whakarereke te auau ki te rite i runga i te tuku me te kaiwhiwhi. Na te take, ko te Whakanui Hiko me te auau antenna me whakarereke i te auau ano. (Me hoko koe i te whakakaha hiko me te antenna mo te kaiwhakawhiti me te kaikawe ki te whakatutuki i to huringa huringa).
3. In order to improve the sensitivity of transmitting and receiving, the frequency bandwidth is generally made very narrow (center frequency ±15MHz, so bandwidth should be 30Mhz). The power amplifier of the transmitter and the frequency of the antenna are specially customized according to the frequency you need.
4. It is best when you place an order, please tell me what kind of working frequency you need. Our engineers will modify the frequency of the transmitter and receiver, and also modify the PA and custom antenna according to this frequency range to ensure the best sensitivity and support the longest transmission distance.
5. Ko te auau taunoa ko 590Mhz, Ki te 30Mhz (+/-15MHz), ka taea e koe te whakarereke me te kore e whakarereke i te Whakanui Hiko me te antenna. Hei tauira, 578MHz, 584MHz, 590MHz, 596MHz, me te 602mhz.
6. If you need to modify the transmitter frequency and bandwidth, you need a special tool of the parameter configure board, please see the below picture, it is not a default accessory, please buy it at an extra cost or contact us before ordering.

Ae, tautoko ana ki te tuku i te ataata me te raraunga UART mai i te kaiwhakawhiti me te kaiwhiwhi.
I te mea he huarahi kotahi te tuku, na e kore e taea e ia te tuku i te whakahau mana mai i te kaiwhiwhi ki te kaiwhakawhiti.

Mena ka hiahia koe ki te tuku i nga whakahau whakahaere, i etahi atu raraunga ranei mai i te kaiwhiwhi hei whakahaere i etahi atu taputapu penei i nga kamera, i nga drones ranei i te kaiwhakawhiti., ka taea e koe te taapiri i tetahi huinga taputapu tuku mamati iti, whakapā tatou, a ka taea e matou te whakarite mo koe.

2. Ka taea e te tawhā whakawhiti te whirihora i te poari te whakatika i te whakahekenga tohu i runga i te kaikawe. Per 0.3db will reduce the 0.5W PA.

pātai: Is it possible to change the outpout power (internal PA 0,5 w, 1 w, 2 w) via the configuration board?

1. As answered above, you can adjust the output power by setting the parameters of ATTEN through the parameter configuration board tool on the transmitter. (This tool does not include the default package, you need to notify that you want to have this tool when you order)
2. Mena ka hoko koe i te 2W PA, katahi ka taea e koe te whakarite 0.5W, 1W, engari kaore e taea te huri ki te 5W.
3. Ka taea hoki e maatau te 5W, 10W, 20W, me te 50W mena ka hiahia koe ki te tautoko i te waa-roa.

No.

Ko tenei kaiwhakawhiti ataata ahokore e tautoko ana i te kamera CVBS me te whakaurunga ataata ranei, Ko etahi atu momo kaamera ataata e hiahia ana he pouaka kaitahuri taapiri.

No. Ko te COFDM (DVB-T) hangarau.

Na ko te awhe auau COFDM ko 170-860Mhz. Ka taea te tautoko 477, 610, 675, 724, 816MHz, engari kaore e taea te tautoko 970, 1180, 1230 MHz.

Ka taea e ta maatau kaiwhakawhiti tauira motuhake te tautoko i nga awhe o runga ake nei, engari me whakamahi te kaiwhiwhi i te poraka whakaheke.

Kia taea ai e taatau punaha tuku ahokore te tautoko i te whanui whanui me te kaha ake o te tohu, ka whakaritea e matou te auau whakahaere ki tetahi waahi (170~860Mhz), and its supported range is only plus or minus 15Mhz. Hei tauira, the center frequency is 590Mhz, max support frequency range should be 575Mhz~605Mhz, The PA and antenna are specially customized according to this center frequency.

1. Ae, there are three solutions to do that.
2. TX900 has three data ports. Distinguish through different transparent serial ports, such as D2 to control relay aircraft and D3 to control mission aircraft. The disadvantage is that the TX900 receiver needs to be connected to two serial ports to send instructions separately.
3. Use the same transparent serial port to send data in bulk, and then add layer protocols (such as header information) to the data to distinguish which aircraft should receive and process the data. The disadvantage is that the processing of sending and receiving data is complicated.
4. Or use two receivers: One receiver is for the mission plane (tuku), and another receiver is for the repeater drone. The connection and operation are easier.
