Multi-Remote Receiver Switch (MRMS)

Multi-Remote Receiver Switch (MRMS) Quick User’s Instructions

1.) Calibration needs to be done before the first time the MRMS is used or whenever the receiver or receiver channel is changed. The calibration process is to tell the Multifunctional RC Motion Switch (MRMS) the maximum and minimum strength of signal from the receiver. Turn the disk switch to the 0 position and connect transmitter power/sign al plug to your receiver.

2.) The following is an example by using channel five to control The MRMS. Alternately, you could choose another channel controlled with a toggle switch. The wiring connections are shown below. The power for the MRMS is from the receiver. Please note that you should not connect the outside or auxiliary power to the MRMS before calibration is completed. A faulty trigger event would result.

With the MRMC plugged into the gear channel of the receiver, turn on the transmitter and the receiver. The gear switch controls channel 5 on the receiver. Toggle the transmitter gear switch back and forth to let the MRMC calibrate/record the resultant signal voltages of the gear switch. All the green LED lights will be flashing while the calibration process is being completed. The green LED lights will turn off automatically as soon as the calibration process is finished. You may have to toggle the gear switch several times.

4.) While mode 0 on the rotating disk switch is used for calibration, modes 1-9 are normal operating modes. Modes 1-5 are considered special purpose and are to be used for driving rocket igniters/glow-plugs. The power only lasts for 0.5 second and will protect the MRMC from burning out. We will setup and drive an igniter/glow-plug in this example. Set the MRMC disk switch to Mode 1. Customers can download the details of other modes in the user manual that is available on the ‘files’ tab of the product’s web page. Turn off the receiver signal power and then connect the power again. Mode 1 is set and ready for use. The first on-off cycle of the gear switch will ignite output position 1 (which is the bottom set of pins in this picture), the second will ignite position 2 and so on through all 7 cycles of the gear switch.

Igniters) triggered) or channels currently being energized by showing a solid green LED at the moment the gear switch is operated on the transmitter.

6.) Pull the transmitter gear switch back and forth quickly (less than 0.5 second) and an event is triggered. The LED(s) progression is lit, and the controlled ports are triggered at time of pulling gear switch. The switch toggle back and forth action should be no longer than 0.5 second so that an event won’t be triggered accidentally by a long duration switch change.

8.) As a safety precaution, you should short or twist the wires of igniters during storage. This will prevent the igniters from being accidentally set off by static electricity.

11.) Connect the appropriately sized auxiliary power and test each of the 7 channels through the transmitter to ensure each channel is working normally. The auxiliary power source is chosen to correspond to the power needs of the items being powered by the 7 channels. In addition, the user needs to know the trigger order of each channel well. This information is found in the manual downloaded as explained previously.
