Second Generation Transmitters
Here are some additional pictures and information about our new transmitter devices:
The Second Generation transmitters are based on the well-known Airwave modules: AWM630, AWM631 and AWM 633. Our transmitters are color-coded. Blue represents the 10mW, green the 40mW and red the 450mW power option. The new design allows you to run these transmitters from 1 to 6 cell batteries without overheating. The running temperature of the TX's(even the 450mW) will vary between 30 and 40 degrees Celsius. Test results show that the temperature of the 450mW TX, on a single 650mA 3 cell battery, running in a 24 degree Celsius environment for 45 minutes, does not go over 40 degrees Celsius. |  |
 | The size of these transmitters is hardly larger than a 2 cell 800mAh LiPo battery. Each transmitter has a built-in camera and power connector. The camera connector has 4 pins: GND, Audio, Video and +5V. The latter supplies power for your Kx-131 or other 5V cameras. |
| The tansmitters are composed of two different boards: one for the power and the other for the TX module. These boards are interconnected and secured with 8mm standoffs and screws. For increased protection a colored heat shrink is applied. |  |
 | If you wish, you can cut off the colored heat shrink, and cover the transmitter with a transparent one in order to show the stylish red boards. |
The DIP switches are easily accessible, and at the same time, well-protected to prevent accidental channel switching. Why 4 switches? - you may ask. Four switches are required to make the transmitter compatible with our earlier receiver models. |  |
 | A connector set is available to connect your camera and power supply to the transmitter. It follows the standard color scheme: black for GND, red for power, yellow for video, and white for audio. |
How much does it weight? See the picture on the right. This scale can measure only in 5gr increments, therefore the TX weighs between 20-25gr. (Covered with the heat shrink, it will be closer to 25gr.) |  |
 | The picture on the left shows a simple plug and play setup. As you can see, the KX-131 is plugged into the TX with only one cable. No additional power supply or power cord is required. The power pigtail with the switch is an optional component. |
| Many people damage their LiPo batteries by forgetting the TX on due to the lack of any indication about the system still being under power. For this reason, we built in a small, low-consumption red LED, which is lit when the TX is under power. |  |
