The distance of 1000m is a theoretical data, it shall be operated in an open ground, no barriers, no any interference. But in the practice, it will be hindered by trees, walls or other constructions, and will be exposed to some interference by other signals. Therefore, the actual distance may or may not reach 1000m.
Waterproof case with external telescopic antenna.
If you stretches the external telescopic antenna, it can have a further working range, which is twice as much as it used to be.
Length of External Telescopic Antenna: 100mm / 460mm (stretch)
The transmitter has farther working range with external telescopic antenna.
With SMA connector
Modulation Mode: ASK
Operating Temperature: -20 ° C to +70 ° C
Unit Size: 100mm x68mm x 50mm
Uses: garage doors, motorcycles, car alarm products, home security products, wireless remote control products, industrial control products.
How to set up the 8-bits code of the transmitter:
1.Open the transmitter shell, then you will see the circuit board. There are two rows pads and one row of chip feet on the back side.
2.The upper row of pads is “L” side, and the lower row of pads is “H” side.
3.If solder the middle row of chip feet to the “L” side, it is code 1. If solder the middle row of chip feet to the “H” side, it is code 2. Don’t solder to any side, it is code 0.
4.The 8-bits code order is from left to right (from A1 to A8).
5.Here is an example, the 8-bits code in the picture is 00010121, solder as the following way:
6.Code 0: don’t solder any side, like A1、A2、A3、A5.
