Features
5.1 Door lock control
The receiver sends
“
LOCK
”
signal to door-lock controller when LOCK button of transmitter was pressed. The
receiver also sends
“
UNLOCK
”
signal to door-lock controller when UNLOCK button of transmitter was pressed.
These facility doesn
’
t work if the key is inserted the key cylinder or the door is open.
5.2 Automatic locking
The receiver sends
“
LOCK
”
signal to door-lock controller if the door has not opened within 30 seconds after
UNLOCK button of transmitter was pressed. This facility helps accidental pressing the UNLOCK button such as
the transmitter is a pocket.
5.3 Battery saving
Because of the power source of the receiver is car battery, it is very important problem to minimize a power
consumption. The receiver
‘
s CPU works intermittently to prevent the battery exhaustion.
5.4 Receiver exercise software
The normal transmission operation of the receiver is conducted by a battery which is installed within a vehicle.
For the measurements purpose a regulated DC power supply is used instead the battery of the vehicle. The
reception of the receiver was conducted by operating intermittently a transmitter with the lock condition. There
is no difference between the lock and unlock condition regarding the electrical and mechanical functions of
a receiver. Also there is no deference between both conditions regarding the frequency of radiated emission.
The only difference is the reception time. The following is no explain the difference:
a) A receiver received the transmission code from a transmitter when the receiver is the
“
ON
”
condition.
b) The
“
ON
”
condition of the receiver continues until the reception of the transmission code shall complete.
c) After the reception of the transmission code shall complete, a door lock actuator shall operate.
