Couple questions:1. When the transmitter goes out of range or loses power, how does the receiver react?2. What does the VT pin do?3. Can I use one transmitter to talk to several receivers (one at a time) by using an Arduino to change the coding bits on the transmitter to match different receivers?4. Why doesn't the transmitter send when D1-D4 are all low? Also, how does the receiver react to this condition?5. How often does the transmitter update the receiver?<br/><br/>

Sorry about question 2. I overlooked what the pictures said.

Again, sorry for my ignorance. By looking at the transmitter's encoder circuit, the encoder is powered by one or more of the inputs being high (diode OR). And it seems to me like the transmitter updates at the osc frequency. At this point, I'm just thinking of removing the encoder and decoder like Alex. Does the RF transmitter just accept a HIGH/LOW signal? Also does the removal of the encoder and decoder change the overall transmission range?

If you are looking for a money pit, then you just found one. this will not work to transmit any data signals (no wireless data transport). you will not be able to use this device to transmit serial data. the fastest signal it can transmit is a 2Hz (while not compromising signal quality) yes a two Hertz signal (that pretty jokes right?) the only thing this works for is a remote detonator, or wireless digital switch. It would have been nice if someone told me this before i spent the money. you people really need to be more honest with your advertising. karma is going to have it's way with you yet...........PS: I am an electronics engineering technologist.

Hello everyone.My name is Ramon and I am new, I would like to know if this module can be extended with other modules.For example. Instead of 4 channels, pass to hold 8, 12, etc.Thank you and best regards to all.<br/><br/>

Does RF Transmitter and Receiver able to transmit data (eg.hello) in open space upto 2km.if more than one RF transmiter transmit the data ,does one rf receiver able receiver the data of more than two transmitter at a time

Hi FAHIM, this couple of wireless module is not able to transmit character data, it only used for transmitting HIHG/LOW signal. You could have a look at RFbee or XBee Pro Chip Antenna - S1.

you can encode on single channel with low bitrate ASK (amplitude shift keying) using arduino or other MCU on both ends.

I assume that if the output is driven by a UART and the receiver inputs it into a UART that serial communication will occur. What is a good speed to use?

can multiple transmitters and receivers be used simultaneously in the same area (room)?

Basically is OK. But you need to keep them maintain at least 1m distance.

Hi There,Does this kit support point to multipoint commuication. In other words, can I use one transmitter and make as a master transmitter to transmit to many receivers ??<br/><br/>

Hello,Can you use multiple of these in the same area? I mean, can you adjust the carrier frequency to transmite information from different sources to different receivers. Thank you.Enrique Marquez

The transmitter/receiver pair worked beautifully. The documentation was pretty bad, but by reviewing the comments on this website it was fairly easy to understand how the units operate. Note that you are not required to adjust any of the encoding pin
