常見問題

1. What should I do when I found one Tx module doesn't generate RF output power?

COFDM-Transmitter-Module — COFDM-發射器糢塊

問題1: 你可唔可以話我呢個組件嘅零件號啊？, 我哋嘗試搵到本地並檢查. 答 1: 佢係一種名為LOH32PN2R2NNC嘅電感.

COFDM-Transmitter-Module-no-tx output power — COFDM-發射器-糢塊-無發射輸出功率

建議檢查點: 如果板子的電源電流良好但沒有射頻輸出, 或者係下面嘅組件 TC1-1-13MX+ 一般損壞.
為避免在運輸過程中損壞本設備 (the device itself is relatively high), we ordered red glue protection for this device when we shipped it.

The engineer also suggests that you check to see if the cable is loose or in poor contact.
Please try to replace the FPC cable connecting the two boards
We can provide spare parts if you're sure which one.

2. Can you offer me the UART AT command file for this model?

確定

3. How does this COFDM Video transmitter and receiver support an IP camera?

1. It is not easy to connect to IPC for a one-way COFDM link. We have an H264 model, which is connected to IPC input by expanding the network port, but there are requirements for IPC models (並非所有型號的IPC都可以與COFDM鏈路很好地連接), 我哋有測試海康威视, 大華, 和雄邁, 並發現連接效果海康威视係相當理想嘅.

2. 無法直接刪除 HDMI CVBS編碼器並將IP攝錄機連接到COFDM發射器板. COFDM單向連接IPC需要特殊嘅技術方法才能實現.

3. 最好嘅方法係舉薦使用我哋嘅雙向圖像傳輸收發器, 直頭支持網絡攝錄機.

4. 如果客戶必須使用COFDM發射器板嚟撐IP攝錄機, 有兩點需要注意.

5. 第一点係技術問題. 我哋需要使用另一種方法嚟允許單向COFDM鏈路與IPC一起使用.

6.如果從降低成本的角度考慮IPC, you don't need to consider it. 因為編碼板和解碼板還是需要嘅, 成本無法節省.

7. The second point is the customer's usage habit, 唔再係傳統嘅雙向連結方法. 佢哋可以查看IP攝錄機視頻，甚至可以透過網頁或PC端PC軟件控制IP攝錄機嘅PTZ (UART AT命令).

8. 由於呢種型號，無線鏈路係COFDM單向鏈路; 冇反向數據 (僅單向傳輸; 數據無法由接收器傳輸到發射器); the customer can only watch the video of the IP Camera and cannot reversely configure the IP Camera's parameters or control the PTZ of the IPCamera.

9. 係好多客戶開始忽略嘅問題，後來使用後才抱怨.

10. So we don't recommend that the client choose a one-way COFDM transmitter and receiver for the IP camera. 我哋為IP攝錄機提供了更好嘅解決方案，通過兩個視頻鏈路收發器.

4. 你可唔可以畀我所需嘅C/N啊 (BER=2x10-4維特比後) 對於不同嘅帶寬 2, 4, 6, 同 8 我哋使用嘅HDMI視頻鏈路嘅Mhz?

1. 現時, 接收器僅提供信號強度和誤碼率兩個參數, 並且冇C/N參數

2. 根據不同的帶寬需要調整哪些參數? 如果係視頻代碼流, 發射器編碼板本身會根據當前使用嘅無線參數自動計算出合適嘅視頻流碼率 (帶寬, 地理標誌, 鉻, 等), 並且視頻碼率會隨著參數板嘅帶寬變化而自動適配.

3. 问题。, 如果我哋嘅相機質素對兩者都足夠好 4 mhz 同 8 mhz 帶寬. 在這種情況下, 如果客戶選擇 4 MHz 或 8 MHz?

答: 我哋嘅單程COFDM貨件默認使用4Mz無線帶寬, 對應視頻比特率為3.12Mbps, 對於1080p來說有足夠; 如果喺相同條件下更改為8MHz無線帶寬, 視頻比特率翻倍至6.24Mbps. 所有客戶都可以喺無線帶寬4MHz同8MHz之間進行選擇, 甚至6MHz都可以考慮.

4. 问题。: 從接收靈敏度视圖來看，邊個更適合此tx+rx集?

答: 用于無線連結, 可以簡單地認為，在較低的無線帶寬下，接收靈敏度會更高. 從接收靈敏度嘅角度來看, 4MHz>6MHz>8MHz

5. 調製器輸入中标配嘅HDMI版本係乜嘢?

HDMI 1.4

6. 你哋有用于無線視頻發射器和接收器嘅COFDM中繼中繼器糢塊呀？

確定

7. 可以向我發送靈敏度嘅數據測量值 4/6/8 MHz案例? 例如, 用于QPSK, 1/2鉻, 1/32GI what threshold reception RX's input level (Dbm)?

單通道接收靈敏度:

-97+/-1dbm QPSK 8MHz緊嗰時,

-98+/-1dbm QPSK時為6MHZ,
使用雙天線接收時靈敏度提高3dbm

8. 此糢塊是否支持1.4G以上? 例如2.4G, 3g, 還是3.6G？

系嘅, 支持.

9. 喺邊度可以下載UDP播放器? 我哋推薦我哋經常使用嘅Splayer_v4.2_2020.6.6.

接收器默認固件支持RTSP播放器, 一些客戶更喜歡UDP播放器, 我哋都可以提供, then RTSP player doesn't support. （ RTSP同UDP只能由兩個固件中選擇一個）
