OKA- 360R
Transmitter, RF Keyless Entry System
1. Constitution of the Radio Frequency Keyless Entry
System for vehicle
The radio frequency keyless entry is a system that it controls locking and unlocking the door and the
trunk and the panic by wireless remote controller. This system consists of three components. The TRANSMITTER is
a device that transmits the signal when the button is pressed. The transmission signal consists of several
synchronous codes, unique identification code, security code and function code and crc code. The RECEIVER is
fixed inside the vehicle. It works intermittently to prevent the battery exhaustion. When the receiver detects the
synchronous code, it runs continuously to receive the signals completely. After receiving the signal, the receiver
decides which operation will be performed.
The user can select the following operations by pressing the button of the remote transmitter.

5.Features
5.1 Door lock control
The LOCK relay in the receiver drives the door lock actulators to "LOCK"-side when LOCK button of
transmitter was pressed. The UNLOCK relay in the receiver drives
5.2
Battery saving
To prevent the battery exhaustion , the micro-computer of the transmitter is usually inactive. When the button
will be pressed, the micro-computer wakes up immediately and judges which button is pressing. Then the
micro-computer constructs the transmission frame and radiates it from the antenna .After transmitting, the
micro-computer switches stand-by mode by itself.
6. Derivatives
OKA-360R is an integrated controller for a car body control, includes the keyless entry receiver.
The integrated. controller consists of the multiple control functions as follows, centralized door lock,
turn-signal lamp, room-lamp, intermitted wiper, power window timer, ignition key illumination,
warning buzzer and so on.
