Question from customer:

I am interesting of buying 2 receivers with one transmitter with the higher actual distance. I want with one transmitter to control separate these two receivers which will be in the same place. I want also only vibration mode and when I press and hold the button the receiver start vibrate until I release the transmitter’s button. Please suggest me a kit for my needs.

Answer:

We recommend two vibration receivers (Z-04) and one long range transmitter  (CB-2). It can realize wireless control when it pairs with transmitter from any place within a reliable distance; the wireless signal can pass many obstacles like walls, doors and doors. It is only vibration mode in that receiver. Those two gadgets will be configured in advance so that they can work together.

Question from customer:

I want a transmitter and receiver (2 remote distance 1000m) for operating a portable jack with a timer 20 minutes.

portable-jack

Answer:         

We recommend the model : 1 channel long distance remote module with adjustable timer (S1DA-AC220-ANT2 & CB-2). This module includes two parts: one is transmitter, the other is receiver. We add external extended antenna to make their transmission distance reach 2000m when transmitter separate from receiver. This kind of controller uses radio frequency to send signals. These signals are transmitted at a particular frequency. A receiver can receive those signals only if it is configured for that frequency. It can realize time delay function because we insert timer on the PCB board. Timer is adjustable from 0 second~99 hours. You can set time freely as you want.

Here is the wiring. We will wire portable jack to B&C dry contact terminals. A wire is connected to B &N terminals. Another wire is connected C&L terminals. At last, we add power to receiver.

circuit

Press buttons of “+”and “-” on the timer, adjust delay time from 0 second to 99 hours. “H” is Hour, “M” is Minute, and “S” is Second. For example, you want to set 20 minutes delay time. You set “M 2 0”. In order to check control module’s working statues, we can plug a lamp to that jack.

Press big button: Turn on jack and turn on lamp (connect B and C, disconnect A and B).

After delay time: Turn off jack by itself, then lamp will off latter (disconnect B and C, connect A and B).

Press small button: Turn off jack immediately, no need to wait for delay time. Lamp is also off at once.

Question from customer:

“I have a classic car with a 12 volt electric wolf whistle. I’d like to trip the wolf whistle from outside the car during cruise nights. How would I accomplish this?”

wolf whistle car horn

Answer:

We recommend the model of 6000ft 6V/9V/12V/24V power output remote control kit (S1X-DC06/09/12/24-ANT2 & CB-2). Usually, 12 volt is default voltage for this kit. If you input 12 volt power to that receiver, receiver will output 12 volt for your wolf whistle horn. It is easy to practice with using of rf remote control because rf signal has advantage of passing through doors, walls, trees as well as other obstacles and long distance transmitting. We add external extended antenna to extend the range of the remote controller and make its transmission distance reach 6000ft/2000m in the open field.

Wiring is very simple. You can wire your wolf whistle horn to output terminals of receiver directly.

The outputs from the receiver can drive relay connected to your wolf whistle horn. Your device will work.

circuit

Usage:

Setting different control modes (We have set the receiver as Toggle mode before delivery. If you want to use other modes, do as following):

1) Setting control mode Toggle: Only connect Jumper-2.

Press big button: Turn on the relay, terminal A&B output DC power.

Press big button again: Turn off the relay, terminal A&B no output.

 

2) Setting control mode Momentary: Only connect Jumper-1.

Press and hold big button: Turn on the relay, terminal A&B output DC power.

Release big button: Turn off the relay, terminal A&B no output.

 

3) Setting control mode Latched: Do not connect Jumper-1 and Jumper-2.

Press big button: Turn on the relay, terminal A&B output DC power.

Press small button: Turn off the relay, terminal A&B no output.

 

General speaking, you can set Momentary mode for wolf whistle horn. When you press a momentary button, your wolf whistle horn stays on as long as you maintain pressure on the button. When you stop maintaining pressure on the button, your wolf whistle horn stops sounding.

Question from customer:

I would like to use a 12v DC electric current to tell a remote to send a signal to the receiver. Do you have any remote transmitters that accept a current instead of requiring a button to be pressed?

Answer:

We recommend the DC 5~28V triggered transmitter (CB-2V). With external input wires, your dc12V electric current can be input transmitter CB-2V. Transmitter can be triggered at once and transmits an rf signal “ON”. When stop inputting DC power, the transmitter is triggered and then transmits an rf signal “OFF”. So this remote control transmitter can accept a current instead of requiring a button to be pressed. Its transmission distance is about 1000m/3000ft theoretically.

low current triggered transmitter

You can add a rocker switch between transmitter and its power supply. (the following picture shows)

current triggered

And you can make this transmitter work with a receiver. (Just like picture shown). When transmitter transmits “ON” signal, the lamp is on; When transmitter transmits “OFF” signal, the lamp is off.

Question from customer:

“I received the item— 2 channel motor controller( S2PF-DC12+1CV-6-2) and installed it yesterday on my remote control lawn mower that I have made. Per the instructions for momentary control, I can get 1 motor to work at a time, either motor but only one and only in forward. I then changed, per your instructions for latch and each motor will go forward if started with remote, #1 and then #2 both will run forward only, but they cannot be controlled to go in the direction that I choose. Neither motor will reverse in any mode. I have to be able to control each motor independent of each other so I can drive the mower right and left to go the direction I want. Please advise!”

lawn-mower

Answer:

You chose the 2 channel motor controller. Although the controller has two relays for two motor, two relays will work in the same mode. That is to say, your two motors only work in momentary mode or latched mode for one time. We recommend two sets of 1 channel dc motor controllers (S1PF-DC12+1CV-4-2), which is only 30amps output and 500m/1500ft transmission distance. It controls DC motors of rolling blinds / doors, projection screens, awnings, pumps, winches, conveyors or other appliances and mechanicals with voltage DC12V / 24V. There are two transmission frequencies, 315Mhz /433Mhz for this controller. You can install one controller set in 315Mhz to one motor, and install another controller set in 433Mhz to another motor, so that you can control each motor independent of each other. Each motor can be controlled by its only transmitter. It won’t generate any interference each other.

1_01_1

Usage:

Connect power supply DC12V / 24V to terminal “INPUT”; connect motor to terminal “OUTPUT”.

1_06

Setting control mode Latched: Do not connect Jumper-1 (CN1) or Jumper-2 (CN2)

Press button ▲: motor rotates in positive direction

Press button ■: motor stops

Press button ▼: motor rotates in reversal direction

Press button ■: motor stops

Setting control mode Momentary: Only connect Jumper-1 (CN1)

Press and hold button ▲: motor rotates in positive direction

Release button: motor stops

Press and hold button ▼: motor rotates in reversal direction

Release button: motor stops

Each receiver has two controlling modes, so you can set receiver 1 for latched mode and receiver 2 for momentary or set receiver 1 for momentary mode and receiver 2 for latched mode.
