1 Qingdao Ruimou Electronics Co., Ltd RMILEC 2.4G RF module Operation Instruction 1. Read the Full Contents of the Instruction Carefully 2. Installation Fix the module into the card slot of the transmitter to fasten the clip firmly. If it can t be fastened, please adjust the clip to bend outwards for about 30 degree. Fix the antenna rack and RF cable, connect the SMA adaptor to the module RF output connector and antenna port. Tighten and then you can power on for the following operation steps. If the antenna is not well connected even without connected,turn on the module will be burnt in a short time,or the performance be reduced.

2 Please use flat antenna for long time using to prevent the electromagnetic radiation damage. 3. Match Initial status Transmitter System info: ID address. Mode Receiver System memory : blank

3 Coding process Transmitter System info: ID address. Mode Sending system Public Address Package Transmitter info: ID address. Mode Receiver Receiving Public Address System memory : Transmitter ID address. Mode Operation: press the utility button to turn on, the transmitter enters the coding transmitting status, then the LED will flash twice in every second. Insert the short jumper to the receiver s ID SET socket, and then power on, it will flash constantly after receiving the ID information from the transmitter, the flash will be about twice per second. Otherwise the receiver will flash slowly, which will be about once every 2 seconds.

4 Schematic Diagram of Using the Coding Short Jumper Can be only used after the receiver and transmitter re-powered, the rematching is not necessary in the future if the transmitter not be replaced or change the coding mode. 4. DIP switch 1 (Output) Output of high power and low power, please be cautious to use the high power mode. With internal jumpers you can get more output modes. The output is 28-30DBM in the high power mode The output is 25-27DBM in the low power mode The output is 19-21DBM in the micropower mode

5 High Power Low Power

6 Low Power Micro power 5. DIP switch 2 (Mode) 3 and 16 frequency points hopping frequency of orthogonal encoding modes selectable. In the 16 frequency points mode, After turns on it pre-select 16 channels with best quality to go on orthogonal combination, actually 15 hopping frequency points will be got. According to the differences of signal quality, the module will automatically fit the numbers of the effective frequency points, at least 6 points, that means according to the situation, the module will automatically use 6-15 best points, In the 16 frequency points mode, every turn-on needs to scan 120 channels, scanning process will cost 2 seconds. The

7 advantage of this mode lies in the high anti-interference performance. In the 3 frequency points mode, the 3 frequency points used in last time will be pre-scanned before transmitting. If there s no other signal getting in, the last 3 frequency points will be used continuously. If there s signal getting in, it will re-scan and choose 3 best frequency points. The advantage of using this mode lies in a fast start up speed, and a little higher entire sensitivity with high performance of long range remote control. 3 frequency points mode Signal lost 4.16mS delay Back on line 16 frequency points mode 29.1mS Signal lost delay Back on line 6. DIP switch 3 (F/S) Fail safe setting Enable the fall safe mode, if the receiver loses the signals in normal receiving, sevro will enter the pre-set degree. Close the fall safe, if the receiver loses the signals in normal receiving, the receiver will cut off the PWM signals to the sevro. 7. Fall Safe Setting Turn on the transmitter and receiver, during the receiver working normally, put every stick of the transmitter to the protection-desired position. Then press the utility button of the module for a long time, about 5 seconds later, the receiver will record the current status of the transmitter s 8 channels. 8. Interference Source Scanning Enter into match mode, and then repress the utility button to start the scanning of 120 frequency points. If the interference signal is scanned, the buzzer will make a sound. The situation of current external signal can be judged by the sound. If the sound is regular and lasts for a short time, it means there re a few interference frequency points. If the buzzer makes relatively noisy call, it means there re many interference frequency points. 9. Settings and Effects

8 To improve the system stability, some settings don t take effect at once to decrease the probability of faulty operation when the circuits failed. Match setting, the setting will be valid after the transmitter and receiver re power on. Power setting, the setting will be valid after the transmitter re power on. Hopping frequency mode, the setting will be valid when the receiver is re matched to the transmitter. Fail safe, the setting will be valid after the transmitter and receiver re power on. 10. Receiver s Cables 11. Automation Function Automatic Gain Control (AGC). This function can provide the user with a relatively better communication quality for short-distance use in the event of very strong interference. No manual intervention is needed in the control process, it s completely automatically. But there is 2 premise: 1. the power output of the transmitter in the Low power or micro power setting. 2. The entire 2.4G frequency band receives severe interference. At this time, the transmitter will adjust the transmitting power automatically to cover the interference signal. 12. Self-detected Information Reporting Function UART port, the communication format of this port is RS N1 TTL level. The output data can be checked by using the ordinary serial port observing software. The RF signal status and the communication frequency hopping table aiming at this situation can be observed clearly from the data. The user with common requirement can also utilize this function to observe similar 2.4 G
