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 (טטל מדרגה, 3.3וו) 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 טעקסט, לעמאָשל:
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 |

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 די 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 (געווינען) 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 (כז) and E bit rate (מבפּס). 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 (ביטראַטע) I have to change only B (באַנדווידט)? 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.
דורך פעליקייַט, 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.
