Brief description:

JMP-BE-9237 is a wireless communication module based on 2.4GHz frequency band. It uses communication password to address communication. It does not need to be paired before use. It can exchange data with any device and module within the signal range. The module can automatically switch the receiving/sending mode and can filter out the signal interference of the same frequency equipment, which greatly simplifies the user''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s use. At the same time, it revolutionizes the introduction of the firmware upgrade function, which can continuously improve itself and add new functions.

Module description:
After the module is powered on, the default communication password is 1234567, which can be used directly by the user, but in order to avoid interference by other users, be sure to call the corresponding function icon to change the password during express programming. At both ends of wireless communication, the password must be exactly the same to connect. After the module is powered off, the password set by the user will not be saved. After power on again, the communication password will be restored to the default value of 1234567. Under special circumstances, the data sent by the wireless module may suffer packet loss due to long-term co-channel interference or weak signal.（The module will try to send the data multiple times within the preset time range）At this time, the module will return corresponding information, prompting the user to proceed with the next step. In addition to communicating between the two modules, this module can also be used in conjunction with the JMP-BE-9244 wireless handle produced by our company（The wireless controller mentioned in this manual refers to this model product）.

Precautions:
1. Please try to avoid using in a strong interference environment. If there are multiple Bluetooth or wifi devices around, the communication quality of the module may be affected due to the proximity of the wireless channels used;
2. In a dry environment, the module may be damaged by strong static electricity from the human body or other objects. Please be sure to take anti-static protection before use;
3. This module is only suitable for use in general entertainment or student competitions. It is forbidden to be used in industries, aviation, biomedicine and other occasions. If you need to use it in other fields, please consult the relevant personnel of our company.

Special Note:
This product is fully compatible with the RCU version 2.4G wireless module (JMP-BE-9242), and can be used with JMP-BE-9244 and 9246 wireless controllers perfectly.

 Introduction:

JMP-BE-9246 is a wireless control handle designed based on the 2.4GHz frequency band. It can quickly and automatically connect to the target device. It has practical functions such as point-to-point/point-to-multiple control, 3D gravity control, and password settings. Automatic pairing using intelligent protocol has the advantages of convenient use, simple operation, stable signal, and low power consumption.

Indicator light:

The blue light flashes to indicate that the data is being sent, and the red light flashes to indicate that the data transmission fails. When the red light is always on, it is compatible mode, otherwise it is standard mode（The factory default is this mode）.

Supporting receiving module:

JMP-BE-9237（Crystal head interface, E2RCU, E3RCU applicable）Or JMP-BE-9242（rcu interface, suitable for X3RCU）

Handle function description:
1. Each button of the handle has a one-to-one corresponding key value code（Except function keys）, When these keys are pressed, the corresponding key code will be transmitted to the receiving device. If the key is not released after being pressed, the key value code of the key will be sent repeatedly every 20ms until the key is released;
2. The “OK/ADD” button has the function of “add 20 to the original key value”. If you press this number first, release it and then press the number key（0-19）, Can send the key-value code with the encoding range of 20-39 to the receiving device（At this time, the middle indicator light is always on）. To switch the key value range back to 0-19, you need to press the “OK/ADD” key again（Send indicator goes off）. For example: press “OK/ADD” and then release it. After seeing the sending indicator light is always on, press the number key 4, then the value 24 is transmitted to the receiving device.
3. The usage of the “SET”button is detailed in the introduction below“How to use”;
4. The “ON/OFF” button is the handle“soft switch”, which can force the handle to enter the sleep state or wake the handle from the sleep state. When the handle enters the dormant state, the connection with the target device will be disconnected, and will automatically reconnect after waking up. Generally, after the handle is used up, please turn off the hard power switch on the back of the handle to extend the battery life.
5.“MODE” button is used to set internal parameters（Compatibility mode switch）, Press alone has no effect, and no key value code will be sent.
6. This handle has integrated digital and analog control signals. The joystick has both digital key value and analog value functions. When the user pushes the joystick, the handle will trigger the digital key value code and analog value of the joystick. The amount is sent to the target device at the same time, and the target device can choose to receive the required data.
7. After the middle button of the left/right joystick is pressed, the handle immediately enters the “3D gravity control mode”. At this point, the handle will continuously transmit its own gravity data to the target device in real time（At this time, the sending indicator keeps flashing）, The time interval for transmitting data is 20ms. To exit this mode, press the middle button of the left/right joystick again.

Equipment characteristics:
1. The power supply voltage of the remote control is 3V, using two 1.5V No. 7（AAA）Battery powered;
2. The linear propagation distance is at least 10 meters in an unobstructed and interference-free environment;
3. If there is no operation for more than 5 minutes, the device automatically enters sleep mode（Send indicator light is always on）.

Precautions:
1. Please use two AA alkaline dry batteries, do not mix new and old batteries;
2. If the device is not used for a long time, please remove the battery to avoid leakage;
3. This device is only for use in primary and secondary school competition applications! !
