Usage Manual for NT-R18C

315/433.92MHz ASK RECEIVER

Description

NT-R18C is our latest high performance anti-interference receiver module, it’s a single-conversion.super-heterodyne receiver architecture and incorporates an entire Phase-Locked Loop(PLL)for precise local oscillator generation. And can use in OOK/HCS/PWN modulation signal and demodulate to digital signal. It has obvious advantage to current other modules of a kind.

Features

• Low power consumption.
• Easy for application.
• On-Chip VCO with integrated PLL using crystal osciliator reference.
• Operation temperature range:-40℃+85℃
• Operation voitage:5 Voits.
• Availabie frequency at: 315/433.92MHz
• Receiver process microchip: BH4126FV
• Antenna length:24cmfor 315MHz,18cmfor 433.92MHz

Applications

• Various vehicle and electrical bicycle security system
• Remote keyless entry wireless system
• Garage door remote control system
• Home security and other intelligent appliances wireless system
• Wireless mouse etc other automation system

Pin Definition & Dimension & Typical

Remark

1. Receive range is about: 250m with our general remote control (Tested in open area)
2. The aerial is employing soft lead wire or other hard metal (Like telescopic aerial), The length

Should not be too long or too short, otherwise the length will affect the available receiving distance. If the aerial is using soft lead wire, it should be stretched as straight as possible in using and stay away from metal object.

1. The power voltage needs to be stable with low ripple factor and multilevel wave filtering (such as adding ic ball, insuctance, capacitance etc.)
2. If the module works with SCM, it is mended that the clock frenquency of MCU should be under 4 MHz and the crystal is better to be kept away from RF receiver module, otherwise the high level harmonic wave of the crystal will affect communication distance
3. Please note that the super-heterodyne receiving module has signal block problem at working time when it is too close to the remote control.
