OMRON AUTOMOTIVE ELECTRONICS KOREA OKA-620T Transmitter, RF Keyless Entry System Table of contents 1. Constitution of the Radio Frequency Keyless Entry system Controller for vehicle --- 1 2. User's manual (provisionally) ----------------------------------------------------------------- 2 3. Specification ------------------------------------------------------------------------------------- 3 4. Features ------------------------------------------------------------------------------------------- 4 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 alarm the horn 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. 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. -1- 2. User's manual (provisionally) REMOTE TRANSMITTER You can lock and unlock and alarm the horn your vehicle with the remote transmitter. LOCK When you push the LOCK button, all the doors will lock. You cannot lock any of the doors with the remote transmitter if any door is open or the key is the ignition switch. UNLOCK When you push the UNLOCK button, all the doors will unlock. You cannot unlock any of the doors with the remote transmitter if any door is open or the key is in the ignition switch. PANIC When you push the PANIC button, horn will alarm. -2- 3. Specification 3.1 CPU Type uPD789860-xxx(8bit) Manufacturer : NEC Corporation ROM 4kbytes RAM 128 bytes EEPROM 32 bytes Clock frequency 4.19MHz Clock frequency generation CRYSTAL Oscillation Package 20pin SSOP 3.2 RF block Carrier frequency 313.85MHz Frequency generation SAW resonator Modulation FSK Bit transmission rate 100bps or 500bps Bandwidth 120KHz RF output power (field strength) 4000uV/m at 3m 3.3 Others Dimension 56mm x 35mm x 11mm Weigh 22.4g Battery Lithium cell (CR2032) Manufacturer: PARASONIC Battery corporation etc. Operation Voltage DC3V, 10mA Operation Temperature -20℃∼+60℃ -3- 4.Features 4.1 Transmission frame The transmission begins immediately in case of LOCK and UNLOCK and PANIC button is pressed. The transmission frame consists of the synchronous frame and the data frame. The synchronous frame has 30 synchronous codes that it will be used for the receiver to wake up. The data frame consists of 24bit length identification code, 16bit security code and function code. 16million different identification codes are available. The security code is always changed in case of any of the buttons is pressed. The transmission time is typically 600 milliseconds. 4.2 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. WARNING Any changes or modifications not expressly approved by the manufacturer could void the user’s authority to operate the equipment. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operations. -4-
