3 Communication Method
3.1 Frequency hopping
This wireless module employs an FH system as a diffusion method. In the FH system, diffusion signals
with a wide bandwidth are produced by hopping the frequency according to a certain pattern. The
pattern is called a frequency hopping pattern. This device has 31 types of frequency hopping patterns.
The same hopping pattern is set for the wireless machines that are intended to mutually communicate.
figure 4：frequency hopping
Even when the hopping pattern is the same, mutual communication is impossible when a wireless
module randomly hops the frequency. Therefore, in the frequency hopping system, one of the wireless
machines works as a standard, while other wireless machines synchronize the frequency and hopping
timing of each machine by receiving packets from the standard machine. This is called
synchronization.
3.2 Synchronization
The slave switches frequency while waiting for a wireless packet from the master. When a wireless
packet is received, it switches to the next frequency and waits for a wireless packet again. When
received, it is judged that the synchronization with the master was successful. After that, the
slave matches the timing and sends wireless packets to the master.
No timeout is set, even for cases when synchronization is unsuccessful due to a poor communication
environment. It continues receiving until synchronization succeeds. In the case when
synchronization fails during communication for some reason, a maximum of 1000ms is required to
re-synchronize.

4 Communication procedure
4.1 Overview
Communication is done in the following manner：
(1) Right after the power is turned on, the master and slave does not have wireless communication
and is in an invalid state.
(2) For sending/receiving a wireless packet, start the FH operation by inputting the @FHS command
(the master and the slave).
The master initiates RF transmission and reception.
The slave starts RF reception, wait for communication from the master.
(3) If FH synchronization acquisition, slave start also sent. After that, the slave will continue
in automatic synchronization.
(4) By TLC command to set the data you want to send.
(5) In FH synchronization acquisition, it will receive the data periodically from the
communication partner.
If the synchronization is out, it does not receive the data.
(6) To stop sending/receiving a wireless packet, type the @FHE command and quit the FH operation.
4.2 Send command
The command header is "@TLC", the terminator is CR+LF (0x0D 0x0A). There is no response to the
command.
Please send data as a binary data of 14-byte fixed.
Radio transmission will be run every 24ms. By @TLC command, it will update the transmitted data.
If @TLC command is not inputted, the previous data is wirelessly transmitted. If you also send
command has not been entered once, the data of all 0 is wireless transmitted.
【Send (update) format】
@TLC[Binary data 14 bytes][CRLF]
4.3 Received data
The received data is appended "RLC" of 3 bytes as a header.
The Received data is binary data of 14-byte fixed.
Radio reception will be run every 24ms. In a state that can't be wireless communication, it
will not be output to the wired.
【Reception format】Repeat
RXT[Binary data 14 bytes]
1M36Q147-01

4.4 Master communication procedure
(1) After the power is turned on, the master does not perform the wireless communication.
(2) If you want to transmit and receive wireless packet, enter FHS command.
(3) As long as the FH synchronization acquisition, the data from the slave is output to the wired.
The received data will be "RLC" header is added.
(4) If you send the data to the slave, enter the @TLC command. By sending @TLC command regularly,
the transmitted data is updated.
(5) If you stop the wireless communication, enter the @ FHE command.
4.5 Slave communication procedure
(1) After the power is turned on, the slave does not perform the wireless communication.
(2) If you want to transmit and receive wireless packet, enter FHS command.
(3) As long as the FH synchronization acquisition, data from the master is output to the wired.
The received data will be "RLC" header is added.
(4) If you send the data to the master, enter the @TLC command. By sending @TLC command regularly,
the transmitted data is updated.
(5) If you stop the wireless communication, enter the @ FHE command.
4.6 Communication time
Interval of the frequency hopping (switching frequency) is 24ms. This 24ms is one frame. The master
wirelessly transmits (1 packet transmission) at the beginning of the frame. Communication time
is about 1.5ms. The slave that is synchronized with the master wirelessly receives the packet at
the beginning of the frame.
The figure below shows the timing.

5 Other functions
5.1 ID Registration
In order to associate the master and the slave, an ID code is used. Each wireless module has
a unique value.
For wireless communication, registration of the ID code of the communication partner is necessary.
Wireless machines without ID code registration are unable to communicate. This prevents improper
connections.
To make the pairing, in a state in which the closer to the master / slave, and then run the @IDS
command to both the master / slave. In the case of slave, it is possible to register up to two.
Please refer to the description of @IDS command for how the second unit of the specified.
If the pairing is successfully complete, "Pair" response is output, pairing ID code is written
to the memory. In order to perform the normal communication, please do the once reset.
If the pairing is not completed, approximately becomes a time-out within 5 seconds, it is returned
N0 response.
The slave is possible to register the master up to two.
However, communication is carried out in a one-to-one, you will not be able to communicate from
two masters. The slave keeps a connection with the master that initiated the first communication.

6.2 How to use commands
(1) When inputting a command to the wireless module, add 1 byte header for command recognition
(command header) at the beginning of the command, in order to differentiate from regular data.
The command header is “@” (40H).
(2) Command is case-sensitive.
(3) A 2-byte terminator is used to terminate a command. The terminator is [CRLF] (0DH: carriage
return ＋ 0AH: line feed).
(4) The wireless module executes a command process after recognizing a command. For a command with
a response, it returns the response to external devices after the process is completed.
(5) Do not input subsequent commands or data before getting a response.

7 Memory register
The memory register is a register that sets and memorizes operation modes and communication
parameters for the wireless module. These values are read when the power is turned ON, and the
module starts operating according to the setting.

Slave
ＲＥＧ０１：Reserved ［default：００Ｈ］
* Not used in this wireless module. Leave default setting.
ＲＥＧ０２：Frequency hopping pattern ［default：００Ｈ］
* Sets the frequency hopping pattern. It can be set to 00～1E (0～30).
* Master only settings are valid. Slave sets the frequency hopping pattern automatically based
on the information of the master.
* In the initial state, a specific frequency hopping pattern is set. Because it is set to 00H
if you initialize, please set again.
* When using multiple systems within the same area, the frequency may periodically match and
interfere with each other even when the frequency hopping patterns are different.
ＲＥＧ０３：Reserved ［default：００Ｈ］
* Not used in this wireless module. Leave default setting.
