Chapter 2. System Configuration
2– Transmitter Unit
Figure A. Transmitter block diagram
The transmitter unit consists of an Encoder Circuit and a Transmitter RF Circuit.
When the user presses a pushbutton on the transmitter, the Encoder Circuit senses
the pushbutton’s data immediately. The Encoder Circuit then encodes the
pushbutton’s data, combined with the ID Code and a Hamming Code to become
the "control data".
This control data goes to the transmitter RF circuit to modulate a radio frequency
(RF) carrier. The output F signal from the modulator is then sent to the antenna
to generate the transmission signal via an RF amplifier and a low-pass filter.
2–2 Receiver Unit
Figure B. Receiver block diagram
The receiver unit consists of the Receiver/Decoder module and the Relay module.

to the Receiver/ Decoder module. The main functions of the Receiver/Decoder
module are to process the RF signal from the transmitter through the signal
processing circuits, consisting of the band-pass filter, RF amplifier, mixer, IF
amplifier, demodulator, error detection, error correction circuits, and decoder in
order to generate a control command sent to the Relay module to drive the
corresponding relay.
The Relay element is the interface of the Remote Controller to a crane or other
mechanical device. The wiring between the relay contact outputs and the control
circuit (or control box) of the crane or mechanical device can be arranged by the
user.
2-3 Error detection/Error correction by software
F25 system employs the theory of "Error-Control Coding" used on Computer
system, and incorporates the "Control Data Code" and the principle of "Error
detection/Error correction" of Hamming Distance to edit and complete the "Code
Word" was so-called "Hamming Code" which may ensure the control data with
accuracy in process of transmission, and also equip with function of automatic
"Error detection/Error correction" to make sure the safety in operation of F25
system remote control.
2-3-1 Data Stream
As shown as below, before the receiver’s relays output to control the equipment’s
movement, the data including SYNC, ID-CODE, CO AND and SU must be
checked twice to further make sure, so the data transmission becomes more safe

quickly. This indicates that it is performing the Channel Changing function.
4.
When LED changes to flash 4 times in green and goes off, then the Channel
Changing is completed. If LED changes to flash 4 times in red, then the Channel
Changing is failed. You must go back to step 1 and redo the procedure again.
5.
After completing the Channel Changing, turn the rotary key from “ON” to “OFF”
position and follow the correct power on procedure. Then, the controller is ready to
be normally used again.
3-5-2 Remote Pairing
Remote Pairing allows the transmitter to actively search the receiver to be paired on
site. After confirming the receiver, the data saved in the receiver, including the
functions settings, ID Code, and the Channel setting, will be download to the
transmitter by radio. In this way, the trouble and the risk of climbing to the receiver
can be eliminated. The procedures are as follows.
1. Depress E S mushroom pushbutton and turn the rotary key to “OFF” position.
2. Depress “START” pushbutton and hold it down, then turn the rotary key from
“OFF” to “ON” position simultaneously. At this time, LED will quickly flash in
red, yellow, and green color alternately. This indicates that the transmitter is in the
remote setting mode.
3. Press the “DOWN” pushbutton. At this time, LED will change to fast flash in
green and red color alternately. This indicates that it is performing the Remote
Pairing function and searching the receivers available on site.
4. When LED changes to flash in green, it means that it has found a receiver ready to
be paired.
5. At this time, you may press the “START” pushbutton to confirm that the receiver
is the one to be paired. The power-on indicator of the receiver that has been
searched will be turned on and the horn will also make a sound at the same time.
6. If the receiver is not the one to be paired, then press “DOWN” pushbutton to skip
it and go back to step 4 to continue the searching process for the next receiver.
7. If the receiver is the one to be paired, then press “UP” pushbutton to continue the
procedure. At this time, LED will change to flash in yellow. It means that the
transmitter is downloading the data from the paired receiver.
8. When LED turns to green, then press “UP” pushbutton to conclude the procedure
above. At this time, LED will change to flash in green 4 times and go off. It means
that the Remote Pairing is completed.
