Users may need to modify the configuration parameters of the module during the use of the COFDM modulator and demodulator module. In order to simplify the user’s operation, we design the parameter configuration into a few simple AT commands. The user only needs to use the specified AT command and pass the corresponding parameters to complete the parameter setting of the COFDM module.

Suitable Models

Command Introduction

The AT command for configuring COFDM module parameters starts with “AT” and ends with an underscore “_”. Each AT command has several or no parameters, and each AT command has a return value. For details, please refer to the introduction of the following commands.

Users can configure the parameters of the module through the configuration serial port (TTL mailako, 3.3V) of the COFDM module. For detailed serial port configuration, refer to the figure below. Please use tools such as “Serial Port Debugging Assistant” to send AT commands to the COFDM module, pay attention to the use of testua, adibidez:

Command Classification

The AT commands for configuring COFDM module parameters are mainly divided into the following two categories:

Query Commands	ATDR, ATGD, ATGE, ATGI , ATGR, ATGT, ATGB, ATGU, ATGIP
Setting Commands	ATSD, ATSG, ATSM, ATSE, ATSI, ATSO, atsr, ATSP, ATST, ATSU,ATOSD, ATSIP

From the perspective of whether to save after power-off, the setting commands can be divided into:

Power-off Saving Commands	ATSD, ATSE, ATSI, ATSO, atsr, ATSP, ATST, ATSU, ATSIP
Power-off Not Saving Commands	ATSG, ATSM, ATOSD

According to the configuration transmitter or receiver, the classification is as follows:

Sender Configuration Commands	ATDR, ATSD, ATGD, ATSG, ATSM, ATSE, ATGE, ATSI, ATGI, ATSO, ATSP, ATST, ATGT, ATSU, ATGU, ATOSD
Receiver Configuration Commands	ATDR, atsr, ATGR, ATSP, ATST, ATGT, ATGB, ATSIP, ATGIP

1. How can I return to the No Password setting with 000000 indications after the change?

Reset the password to 000000 (one must not be missing) through the Parameter Configuration Panel Board.
or set it through du ATSP_command

2. I see that Gain is the output power of the transmitter. Please tell me the range of settings of this parameter. All setting level (Irabazia) good for linear output operation? Or do you suggest some limited range for better linear operation?

The Gain of the COFDM configuration is the internal Gain, not the actual output power of the transmitter. The internal gain range is 0~89.75dB and the linear output:
1. At around 300~500MHz, the Gain is set to 89.75, and the actual output power of the transmitter module is about -5dBm.
2. At around 1000~1500MHz, the Gain is set to 89.75, and the actual output power of the transmitter module is about -6dBm to -10dBm.

3. I tried to set – B bandwidth (kHz) and E bit rate (Mbps). When I set E, the new value does not apply. So. the E setting is only for monitoring of available bitrate? if I wish to change the E (Bit-tasa) I have to change only B (banda zabalera)? Am I right?

It is not recommended to modify the video bit rate ‘E’ directly, because if the output video bit rate is greater than the wireless air interface rate, the system will not work normally.
Lehenetsiz, the internal video bit rate ‘E’ will be set to 0 for automatic. Customers only need to modify ‘B’ to modify the wireless parameters, and the video bit rate will automatically adapt.
You can also adjust the wireless air interface rate by modifying GI and CR.

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

3. Nola onartzen du COFDM bideo-igorle eta hargailu honek IP kamera bat?

1. Ez da erraza IPC-ra konektatzea norabide bakarreko COFDM lotura. H264 eredua dugu, sareko ataka zabalduz IPC sarrerara konektatzen dena, baina IPC ereduetarako eskakizunak daude (IPC eredu guztiak ezin dira ondo konektatu COFDM estekekin), ren IPC-ak probatu ditugu Hikvision, Dahua, eta Xiongmai, eta aurkitu zuen konexio efektua Hikvision nahiko ideala da.

2. Ezinezkoa da zuzenean kentzea HDMI CVBS kodetzailea eta konektatu IP Kamera COFDM Transmitter plakara. IPCrako COFDM norabide bakarreko konexioak metodo tekniko bereziak behar ditu gauzatzeko.

3. Modurik onena gure bi noranzkoko irudien transmisio-hartzailea erabiltzea gomendatzea da, zuzenean IP kamera onartzen duena.

4. Bezeroak COFDM igorle-plaka erabili behar badu IP kamera onartzen duen, erreparatu beharreko bi puntu daude.

5. Lehenengo puntua arazo tekniko bat da. Metodo alternatibo bat erabili behar dugu norabide bakarreko COFDM loturak IPCrekin erabiltzeko.

6.IPC kostuen murrizketaren ikuspegitik kontuan hartzen baduzu, you don't need to consider it. Kodetze-taula eta deskodetze-taula beharrezkoak direlako oraindik, kostua ezin da aurreztu.

7. The second point is the customer's usage habit, jada ez den bi norabideko lotura metodo tradizionala. IP Kameraren Bideoa ikusi ahal izango dute eta IP Kameraren PTZ kontrolatu dezakete web orrialdearen edo PCaren alboko PC softwarearen bidez (UART AT komandoak).

8. Eredu honengatik haririk gabeko lotura COFDM norabide bakarreko lotura da; ez dago alderantzizko daturik (noranzko bakarreko transmisioa; datuak ezin dira hartzailetik transmisorera transmititu); 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. Bezero askok hasieran ahaztu eta gero erabili ondoren kexatu egin zen arazo bat da.

10. So we don't recommend that the client choose a one-way COFDM transmitter and receiver for the IP camera. IP Kameraren bidez irtenbide hobea dugu bi bideo-lotura-transceptor.

4. Eman al didazu mesedez Beharrezko C/N (BER=2x10-4 Viterbiren ostean) banda zabalera desberdinetarako 2, 4, 6, eta 8 Erabiltzen dugun HDMI bideo esteka Mhz?

1. Gaur egun, hargailuak seinalearen indarra eta bit errore-tasa bi parametro baino ez ditu ematen, eta ez dago C/N parametrorik

2. Zein parametro doitu behar dituzu banda zabalera ezberdinen arabera? Bideo-kode korronte bat bada, Transmisorearen kodetze-taulak berak automatikoki kalkulatuko du bideo-korrontearen kode-tasa egokia gaur egun erabiltzen diren haririk gabeko parametroen arabera. (banda zabalera, GI, CR, etc.), eta bideo-kodearen tasa parametro-taularekin banda-zabalera aldatu ondoren aurkituko da automatikoki egokituko da.

3. Galdera, Gure kameraren kalitatea bientzat nahikoa ona bada 4 MHz eta 8 MHz banda zabalera. Kasu honetan, Bezeroak aukeratu behar badu 4 MHz edo 8 MHz?

Erantzuna: Gure COFDM norabide bakarreko bidalketek 4Mz hari gabeko banda-zabalera erabiltzen dute lehenespenez, 3,12 Mbps-ko bideo-bit-abiadurari dagokiona, 1080p-rako nahikoa dena; Baldintza berdinetan 8MHz hari gabeko banda-zabalera aldatzen bada, bideoaren bit-tasa 6,24 Mbps-ra bikoiztu egiten da. Bezero guztiek haririk gabeko banda zabalera 4MHz eta 8MHz artean aukeratu dezakete, nahiz eta 6MHz ere har daiteke kontuan.

4. Galdera: Zein da hobea tx+rx multzo honetarako jasotzeko sentsibilitatearen ikuspegitik?

Erantzuna: Haririk gabeko esteketarako, besterik gabe har daitekeen sentsibilitatea handiagoa izango dela haririk gabeko banda-zabalera txikiagoan. Sentikortasuna jasotzearen ikuspegitik, 4MHz>6MHz>8MHz

5. Zein HDMI bertsio den estandarra Modulator sarreran?

HDMI 1.4

6. Ba al duzu COFDM errele errepikagailu modulurik haririk gabeko bideo-igorle eta hargailurako?

Noski

7. Sentsibilitatearen datu-neurketa bat bidali ahal didazu 4/6/8 MHz kasuak? Adibidez, QPSKrentzat, 1/2CR, 1/32GI what threshold reception RX's input level (dBm)?

Kanal bakarreko sentsibilitatea jasotzeko:

-97+/-1dbm QPSK 8MHz-n,

-98+/-1dbm QPSK 6MHZ-n,
Sentsibilitatea 3dbm handitu da antena bikoitzekin jasotzen denean

8. Modulu honek 1.4G baino gehiago onartzen al du? adibidez 2.4G, 3G, edo 3.6G?

Bai, laguntza.

9. Non deskargatu dezaket UDP erreproduzitzailea? Maiz erabiltzen dugun Splayer_v4.2_2020.6.6 gomendatzen dugu.

Hartzailearen firmware lehenetsiak RTSP erreproduzitzailea onartzen du, bezero batzuek UDP jokalaria nahiago dute, guk ere eskain dezakeguna, then RTSP player doesn't support. (RTSP eta UDP bi firmwareetako bat bakarrik aukeratu dezakete)

Mesedez, deskargatu beheko estekan.

1. How can I return to the No Password setting with 000000 indications after the change?

2. I see that Gain is the output power of the transmitter. Please tell me the range of settings of this parameter. All setting level (Irabazia) good for linear output operation? Or do you suggest some limited range for better linear operation?

3. I tried to set – B bandwidth (kHz) and E bit rate (Mbps). When I set E, the new value does not apply. So. the E setting is only for monitoring of available bitrate? if I wish to change the E (Bit-tasa) I have to change only B (banda zabalera)? Am I right?
