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. No te mau haamaramaramaraa hau atu, please refer to the introduction of the following commands.
Users can configure the parameters of the module through the configuration serial port (Faito TTL, 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 parau papa'i, ei hioraa:
PFommand 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, TE MAU NOTA, 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, TE MAU NOTA, 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, TE MAU NOTA, ATGE, ATSI, ATGI, ATSO, ATSP, ATST, ATGT, ATSU, ATGU, ATOSD |
| Receiver Configuration Commands | ATDR, ATSR, ATGR, ATSP, ATST, ATGT, ATGB, ATSIP, ATGIP |

FAQ
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 te 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 (Ia roaa te) good for linear output operation? Or do you suggest some limited range for better linear operation?

1. I te area matahiti 300~500MHz, ua tuuhia te tapa'o i ni'a i te 89.75, e te mana mau o te tao'a e vai ra i roto i te mau tao'a e vai ra i roto i te reva, fatata ïa i te 5dBm.
2. I te area matahiti 1000~1500MHz, ua tuuhia te tapa'o i ni'a i te 89.75, e te puai mau o te transmitter module, tei nia ïa i te -6dBm e tae atu i te -10dBm.
3. Ua tamata vau i te haamau – Te mau mana'o tauturu no te haapiiraa (kHz) e te tahi atu â mau mea i ni'a i te (Mbps). I to'u haamauraa i te E, aita te faufaa apî e tano. No reira. te faanahoraa E, no te hi'opo'a-noa-raa ïa i te mau mea e vai ra? mai te mea e, e hinaaro vau e taui i te E (Te faito iti) E ti'a ia'u ia taui i te B (bandwidth)? Ua tano anei au?
Aita e faaitoitohia ra ia taui i te faito o te hoho'a video 'E’ I te Taa-ê-raa, no te mea mai te mea e mea rahi a'e te faito o te hoho'a video i te faito o te mata'i aita e niuniu paraparau, eita te faanahoraa e tere maitai.
