When using our COFDM transceiver module, users may need to change the configuration parameters of the module. In order to facilitate customer use, we developed the LCD panel Parameter Configuration Tool (here in after referred to as PCT) for parameter configuration. The details are as follows.

用户界面介绍

OLED屏幕显示:

Parameter Configuration Tool is equipped with a 0.96-inch OLED display to display our COFDM transceiver module parameters (中心频率, 带宽, ETC。) for users to query and change as needed.

Enter Key

Parameter Configuration Tool is equipped with 3 功能按钮, which are used to switch parameter display, or edit and change parameter values ​​as needed.

如何使用?

参数显示

When Parameter Configuration Tool is powered on, the waiting for connection screen will be displayed on the LCD:

After Parameter Configuration Tool successfully communicates with our COFDM transceiver module, the got parameter values ​​of the transceiver module will be displayed on the digital tube. 默认显示基本参数页面. Users can press “向上” 要么 “向下” button to switch to the advanced parameter page.

Parameter modification:

The basic parameters page is displayed by default. If the user needs to view or change advanced parameters, he can short press “向上” 要么 “向下” button to switch to the advanced parameter page.

默认模式下, only parameters can be previewed. If the user needs to change the parameters, please press and hold “菜单” button to enter parameter editing mode.

In edit mode, the edited parameter value will flash. If the customer needs to switch parameters, 长按 “向上” 要么 “向下” Press the button to switch. If you do not need to switch parameters, you can short press “菜单” Press the key to switch the high and low bits of the parameter that need to be edited. The corresponding bit to be edited will flash as a prompt, 然后按 “向上” 要么 “向下” Press the button to increase or decrease the value of the corresponding bit of the parameter.

修改参数后 (Allows multiple parameters to be changed at one time), 长按 “菜单” button, all current parameters will flash (The parameter name and parameter value flash together), then release “菜单” button to complete editing and exit the editing mode. The new parameter values ​​will be written into our COFDM transceiver module.

Commonly used frequency point entry and switching

Commonly used frequency entry methods

In default mode, press and hold “向上” 和 “向下” Press two buttons for 2-3 seconds to enter Frequently used frequency entry page(Maximum configuration allowed4common frequency points)：

COFDM TX/RX vxx

1: 频率 (千赫)

2: 频率 (千赫)

3: 频率 (千赫)

4: 频率 (千赫)

If no commonly used frequencies have been entered before, all commonly used frequencies will be displayed as 000000(Represents not set); If a common frequency point has been set before, 显示对应频点的值.

Frequently used frequency entry page, the edited frequency parameter will flash. If the customer needs to switch frequency, 长按 “向上“要么”向下“Press the button to switch. If you don’t need to switch the frequency point, you can short press “菜单” Press the key to switch the high and low bits of the frequency parameter that needs to be edited. The corresponding bit to be edited will flash as a prompt, 然后按 “向上“要么”向下“Press the button to increase or decrease the value of the corresponding bit of the parameter (If you want to cancel a certain frequency point, you only need to change the parameter of the corresponding frequency point to 000000).

修改频率参数后 (Allows multiple parameters to be changed at one time), 长按 “菜单” button, all current parameters will flash (The parameter name and parameter value flash together), then release “菜单” button to complete editing and exit.Frequently used frequency entry page, return to the basic parameters page, and the new frequency parameter values ​​will be recorded in the Parameter Configuration Tool

Commonly used frequency switching methods

In default mode, 长按 “向上” 要么 “向下” button will be pressed based on the previously entered Common frequency points to switch (Maximum allowed in 4 Switch between commonly used frequencies), the screen will display the frequency point currently switched to (Centered, large font display), and stay for 5 seconds before returning to the basic parameter page:
