Overview:

RXC68 is a super-heterodyne working mode, SAW resonance, with stable and strong anti-interference characteristics, learning type MCU decoding, 8 output channels, direct output high level, can directly apply various products, widely used in higher requirements Industrial control and anti-jamming occasions.

The receiving board has a working voltage of 3-5V, a super-heterodyne circuit, and the single-chip microcomputer decodes eight outputs.

Four signal output modes: self-locking, jog, interlock and self-locking and jog. (Default is non-lock)

Technical parameter:

Working voltage: 3-5VDC

Working current: ≤ 4mA (5.0VDC) working principle: super heterodyne

Working method: OOK/ASK

Frequency range: 315MHz

Band width: 150KHz (315MHz, test when the sensitivity drops by 3dBm)

Sensitivity: better than -112dBm (50Ω)

Decoding format: fixed code, learning code

Output signal: TTL level, eight outputs

Antenna length: 24~28cm (315MHz)

Size: 40*12.5*8MM

Work mode switching:

Function 1: Self-locking - learn with button 1

Function 2: Jog - learn with button 2

Function 3: Interlocking - learn with button 4

Function 4: Self-locking and jogging coexist - learning with button 3

Note: If the learned receiver need to change to other functions, please clear the receiver and select the required button to re-code the code.

Study method:

Press and hold the learning button for about 1 second, the indicator light is on. At this time, pressing any button on the remote control flashes to indicate that the learning is successful; you can learn a number of remote controllers with different codes.

Clear method:

Press and hold the learning button, the indicator light will be on constantly. Press and hold for about 10 seconds, the indicator will go out, indicating that the code has been cleared successfully.

Pin definition:

VT - Decode valid indication output pin (pulse 12345678 eight control signal output pins)

GND - negative supply

VCC - Power Positive DC3-5V

ANT - Antenna

Precautions for use:

1. Use a flexible wire or other hard metal (such as a whip antenna) for the antenna to a length of approximately 28 cm (315 MHz) and use it as straight as possible. Do not approach metal objects.

2. The power supply voltage is stable and the ripple factor is low. Multi-stage filtering is required (such as adding beads, inductors, capacitors, etc.).

3. If the MCU clock frequency is below 4MHZ and the crystal is as far away as possible from the RF receiver module, the higher harmonics of the crystal will affect the communication distance.

4. Note that the rate of the encoding IC and the decoding IC is the same and the format of the code is the same (that is, the oscillating resistance is matched), otherwise the distance will be affected and the communication will not be possible.

Industrial 8-key remote control parameters:

Working voltage: DC6V (4 batteries of AA, the battery is not included)

Quiescent current: 0mA

Working frequency: 315MHZ

Chip Type: Fixed Code (2264)

Oscillation resistance: Default 475

Launch distance: 200-500M (open environment)

Modulation method: ASK amplitude modulation

Package includes:

1 x Remote control
1 x Superheterodyne Receiver Module
