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 “એટી” 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 સ્તર, 3.3વી) 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 ટેક્સ્ટ, દાખ્લા તરીકે:

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 આ 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 (પ્રાપ્તિ) 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 (કિલોહર્ટઝ) and E bit rate (એમબીપીએસ). When I set E, the new value does not apply. તેથી. the E setting is only for monitoring of available bitrate? if I wish to change the E (બિટરેટ) I have to change only B (બેન્ડવિડ્થ)? 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.
By default, 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. Question1: Could you please tell me part number of this component, we try to find localy and check. જવાબ 1: It is a inductance named LOH32PN2R2NNC.

  1. Suggest Check Points: If the power supply current of the board is well but there is no RF output, maybe the below component TC1-1-13MX+ is generally damaged.
  2. In order to avoid damage to this device during transportation (the device itself is relatively high), we ordered red glue protection for this device when we shipped it.

  1. The engineer also suggests that you check to see if the cable is loose or in poor contact.
  2. Please try to replace the FPC cable connecting the two boards
  3. We can provide spare parts if you're sure which one.
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 (not all models of IPC can be well connected with COFDM links), we have tested the IPCs of Hikvision, Dahua, and Xiongmai, and found that the connection effect of Hikvision is quite ideal.
2. It is impossible to directly remove the HDMI CVBS encoder and connect the IP Camera to the COFDM Transmitter board. One-way COFDM connection to IPC requires special technical methods to realize.
3. The best way is to recommend using our two-way image transmission transceiver, which directly supports the IP camera.
4. If the customer must use the COFDM transmitter board to support the IP camera, there are two points to pay attention to.
5. The first point is a technical problem. We need to use an alternative method to allow unidirectional COFDM links to be used with IPC.
6.If you consider IPC from the perspective of cost reduction, you don't need to consider it. Because the encoding board and decoding board are still necessary, the cost cannot be saved.
7. The second point is the customer's usage habit, which is no longer the traditional two-way link method. They can view the IP Camera Video and even control the PTZ of the IP Camera via the web page or PC-side PC software (UART AT commands).
8. Because of this model wireless link is a COFDM one-way link; there is no reverse data (only one-way transmission; data cannot be transmitted from the receiver to the transmitter); 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. This is a problem that many customers overlooked at first and later complained about after using it.
10. So we don't recommend that the client choose a one-way COFDM transmitter and receiver for the IP camera. We have a better solution for the IP Camera via two video link transceivers.
1. હાલ, the receiver only provides two parameters of signal strength and bit error rate, and there is no C/N parameter
2. What parameters do you need to adjust according to different bandwidths? If it is a video code stream, the transmitter encoding board itself will automatically calculate the appropriate video stream code rate according to the currently used wireless parameters (બેન્ડવિડ્થ, જીઆઇ, સીઆર, વગેરે), and the video code rate will be found after changing the bandwidth with the parameter board will automatically adapt.

3. પ્રશ્ન, If our camera quality is good enough for both 4 મેગાહર્ટઝ અને 8 મેગાહર્ટઝ બેન્ડવિડ્થ. આ બાબતે, Should the customer choose 4 મેગાહર્ટઝ અથવા 8 મેગાહર્ટઝ?

જવાબ: Our one-way COFDM shipments use 4Mz wireless bandwidth by default, corresponding to a video bit rate of 3.12Mbps, which is enough for 1080p; If changed to 8MHz wireless bandwidth under the same conditions, the video bit rate doubles to 6.24Mbps. All customers can choose between wireless bandwidth 4MHz and 8MHz, even 6MHz can also be considered.

4. પ્રશ્ન: Which is better for this tx+rx set from a receive sensitivity view?

જવાબ: For wireless links, it can be simply considered that the receiving sensitivity will be higher at lower wireless bandwidths. From the perspective of receiving sensitivity, 4મેગાહર્ટઝ>6મેગાહર્ટઝ>8મેગાહર્ટઝ
