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?

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

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)?

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.

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

What is the max output current per channel? Also, how much current does the receiver consume?
