Specifications: Model: TX118SA Transmitting power: 11dbm Distance: 100-200M Emission current: 10MA Standby current: less than 3A Transmission rate: up to 10KB/S RF offset: +/- 7. 5KHZ / narrowband emission Modulation method: ASK Working voltage: DC 3V-18V Optional fixed coding type: PT2262/EV1527/HT6P20B Customizable special code: MCU type Button data: A, B, C, D a total of 4 groups of inputs, can be combined into 15 groups. Each module has a separate ID address code All the four key codes of the modules K1 - K4 are the same. Pin : -: negative power supply +: Positive power supply, DC 3-18V K1: External input button, short-circuit to ground to start transmitting data 1, which is equivalent to the A button of the remote control. K2: External input button, short-circuit to ground to start transmitting data 2, equivalent to the B button of the remote control. K3: External input button, short-circuit to ground to start transmitting data 3, equivalent to the C key of the remote control. K4: External input button, short-circuit to ground to start transmitting data 4, equivalent to the D button of the remote control. ANT: Transmitting antenna Precautions: (1) This product is a CMOS device and should be protected against static electricity during storage, transportation and use. (2) The device should be grounded well when in use. Package Included: 1 x TX118S Transmitter Module
