II.II Installation Safety Hazards and Notes
Use only the proper regulated DC voltage supplied to the FDP02TJ010.
Use of any other voltage m ay permanently damage the m odem and/or
cause the modem to malfunction and create a shock or fire hazard.
Be certain that all AC power outlets used the power adapters have been
properly installed, grounded, and fused.
An electrical s hock hazard
may exist if this unit is powered by a faulty power outlet or source.
If such a situation is dis covered, immediately discontinue use until the
power source and outlet have been properly installed, grounded, and
fused by an electrician or other authorized person.
Be sure to wire the power and Ethernet connections correctly. Incorrect
wiring can dam age the system , cause it to m alfunction and/or create a
shock and fire hazard.
Ensure that the FDP02TJ010 power a nd the power to the equipm ent to

Ver.1.1
II.III Antenna Installation Hazards and Notes
Be sure to keep all system s and antennas clear of power lines
Permanent equipm ent dam age and severe shock injury or death can
occur if the system contacts power lines.
Contact Futaba before connecting a ny antenna not provided by Futaba
specifically for the FDP02TJ010.
Attaching any non-authorized
antenna may be in violation of FCC regulations.
Before each use, verify that the an tenna (and antenna cable, if used) is
securely attached and in good con dition. A loose antenn a or cable
may severely reduce the operating range of the system.
The FDP02TJ010 operates at frequencies in the 2.4 GHz band.
These frequencies are more directi onal than lower frequencies and are
easily reflected.
If there are m etal structures nearby, the effective
range m ay be shortened or the dir ectional properties m ay be further
narrowed. To help avoid this, mount th e antenna as far away as
possible from surrounding metallic structures.
Multipath p roblems occur easily at frequencies in the 2.4 GHz band.
When m ultipath prob lems are pres ent, m oving the an tenna around 10
cm may result in improved communication or, conversely, worsened or
complete loss of communication.
Futaba recomm ends that the
mounting position of the antenna be dete rmined after testing and
verifying optimal communication conditions.
When installing multiple FDP02TJ010 that will use different frequency
groups in the same area, FDP02TJ010’s antennas of different frequency
groups must be mounted at least 6 feet (2 meters) apart. Failure to do so
may severely reduce the modem operating range.
Please contact Futaba for inform ation about antenna separation when
using the FDP02TJ010 and other wireless products in the same area.
Ver.1.1
II.IV Environmental Safety Hazards and Notes
If the FDP02TJ010 has been stor
ed at a temperature beyond the
specified o perating temperature range for th e system , it m ay not
function pro perly. Allow it to re turn to norm al tem peratures before
use. Refer t o APPENDIX A – TECHNICAL SPECIFICATIONS for t he
actual operating temperature range.
The FDP02TJ010 is a precision electr onic device with a rugged design
that is in tended for industrial applications. However, do n ot install it
where it will encoun ter excessive vibrations. In some cases, isolation
mounts m ay be used to isolate
the m odem from the equipm ent’s
vibration. Excessive vibration can perm anently dam age the m odem
and/or cause it to malfunction.
Do not ope rate th e FDP02TJ010 in environments where it will b
subjected to excessive moisture (such as rain or water spray), dust, oil,
or other foreign m atter (such as metal partic les). Doin g so m ay
permanently damage the m odem and/or cause it to m alfunction. If it
does become wet or contam inated, co rrect the situation, verify proper
operation and have any problem s correct ed before using it to control
other equipment. If necessary, the m odem can be m ounted inside a
protective o r waterproo f enclosure. If the enclosure is m etallic, th e
antenna m ust be m ounted externally or the effective operating range
will be severely limited.
The FDP02TJ010 is designed for indoor use. When using it outdoors,
the m odem should be m ounted in a waterproof enclosure and the
ambient temperature range should be check ed to insure that it is within
the m odem’s specifications. Always use the m
odem within its
specified environmental ranges.

Overview
The FDP02TJ010 (hereinafter referred to as the "FDP02") is a 2.4GHz-band wireless radio modem with a
compact and low power consumption design.
2.
Operating Modes
The FDP02 has the following three transmission modes:
- Packet transmission mode
- Headerless packet transmission mode
- Broadcast transmission mode
2.1
Packet Transmission Mode
The FDP02 supports two types of wireless addresses. One is unique address and the other is group address.
At packet transmission mode, data packets are transmitted to the unique address and/or group address through
the serial port. AT this mode, the packet format should be text or binary data.

Processing of packet transmission and reception
When a packet is inpu t to a sen der FDP02 via the serial port, the sender FDP02 checks whether the packet is
valid.
Then, if the packet configuration is invalid or a t ime gap bet ween bytes is more than 5 sec onds, the sender
FDP02 distinguishes an occurrence of a packet error and ignores the packet. At that time, the sender FDL 01
notifies the occurrence of the packet error if the functions of "Enabling response" and "Enabling N0 response"
in he REG13 are turned on.
If the functions of “Enabling response” and “Returning P1 and P0 responses” in the REG13 register are turned
on, the se nder FDP02 replies a P1 response to the host whe n it receives a valid pac ket data. However, the
sender FDP02 does not return any response if the functions of the REG13 register is different setting. Then,
the sende r FDP02 tra nsmits the packet t hrough wireless transm ission to the destination a ddress, receiver
FDP02.
At receiver FDP02 side, it output the packet data through the serial port if configurations of packet are valid.
At that time, the receiver FDP02 responds an acknowledgement “ACK” signal to the sender FDP02 for
notifying data packet receiving if "Enabling destination address check at reception" function of the REG18
register is turned on. On the other hand, when the function of "Disabling destination address check at
reception" in the REG18 register is turned on, the receiver FDP02 does not return ACK signal to the sender
FDP02 and also it receives all packet data regardless of the destination address of the packet.
Packet data transmission from the sender to the receiver is finished when the sender FDP02 receives ACK
signal. At that time, the sender FDP02 outputs P0 response if "Enabling response" functions of the REG13
register is turned on. When the sender FDP02 cannot receive ACK signal within the time-out limit, the
sender FDP02 transmits the same packet data to the destination receiver through the air if the re-try frequency
is registered. (The re-try frequency can be set by REG11 register
When the receiver FDP02 receives the same packet several times, it ignores from the second data downward.
Ver.1.1
Also, the receiver FDP02 sends ACK signal to the sender FDP02 if the function of "Enabling destination
address check at reception" of REG18 register is turned on.
If the sender FDP02 cannot receive ACK signal even it sent packet data defined times by the REG11 register,
it outputs N1 response to the host device via the serial port when "Enabling response" function of REG13
register is turned on. No response signal is sent if the function of "Disabling response" in REG13 is turned
on
The figure below shows an operation example of data packet communication between a sender FDP02 that the
"Enabling response" and "Returning P0 and P1 responses" functions of REG13 register are turned on and a
receiver FDP02 that "Enabling destination address check at reception" function of REG18 register is turned on.
At the figure, data communication is completed by “ACK” signal retry.
① The Host 1 inputs data to the sender FDP02 via the serial port.
② The sender FDP02 recognizes the data packet configuration as valid and returns a P1 response to the Host
1 (Data is accepted).
③ The sender FDP02 transmits the data packet to the destination, which is the receiver FDP02, by wireless
transmission.
④ The receiver FDP02 receives the packet and outputs the received data packet to the Host 2 via the serial
port.
⑤ The receiver FDP02 returns ACK to the sender FDP02 by wireless transmission.
⑥ Time-out is occurred at the sender FDP02 because it cannot receive the receiver's ACK signal at the first
transmission. The sender FDP02 re-sends the data packet transmission.
⑦ The receiver FDP02 receives the same data packet as the previously received one. Thus, the receiver
FDP02 ignores the received data but returns ACK signal to the sender FDP02.
⑧ The sender FDP02 receives the ACK signal and outputs a P0 response to the Host 1.

After entering a command to the sender FDP02, do not input the next command
until the P0 response for the entered command is returned. Sending a new
command before the P0 response is received, it may cause of command error
and/or unpredictable operation.
When "Disabling response" function of REG13 register of the sender FDP02 is
turned on, the next command should be input after waiting a time period of
expected P0 response.

2.2
Headerless Packet Transmission Mode
By setting "Headerless packet transmission mode" on the REG03 register of the FDP02, the FDP02 transmits
packets by wireless transmission to a destination address that is defined by the REG02 register. At this mode,
a header part (command header "@", command "TXT" or "TBN", destination address, and number of message
bytes [for TBN command]) can be eliminated. The trigger of data transmission can be defined by the setting
of REG24 register. It can be selectable entering of "" (0DH, 0AH) (i.e., carriage return and line
feed codes) or time over of the timeout period (a time gap limit between two data bytes that is set in the
REG26 register). Data transmission is triggered also when the number of message bytes exceeds 26 bytes.
It is also enable to set "Enabling response" and "Disabling response" mode in by the REG13 register at the
headerless packet transmission mode. Additionally, "Returning P1 and P0 responses" and "Returning P0
response" function can be selected when "Enabling response" mode is chosen. Moreover, "Enabling
destination address check at reception" and "Disabling destination address check at reception" function can be
selected by the REG18 register. For more details, see section 2.1 “Packet transmission mode”.
Also, it is selectable whether "" (0DH, 0AH) is added on the received data by the settings of the bit
4 of the REG23 register.
In headerless packet transmission mode, maximum data buffer size for sending
data is 130 bytes and data transmission is started when message data size exceeds
26 bytes. When many message data are input consequently, the message buffer
may be overflowed and the message data may be lost. At that situation, the
hardware flow control function should be set. If "Enabling response" function
is selected in REG13 register, it is possible to judge whether data transmission is
succeeded or not. Thus it is recommended to set "Enabling response" function
even in headerless packet mode.
Additionally, the massage data may be lacked when the size is over 26 bytes.
To prevent for such an event, check each response on the sender and create
messages so that the loss of packets can be detected on the receiver FDP02.
The serial communication speed of all FDP02 should be same setting. If
different serial communication speeds are set between on the sender and the
receiver FDP02, data loss may occur on the slower speed side.

Serial-Output Data Format of Receiver Side at The Transmission Mode
Data format of the receiver side that outputs to the serial port varies depending on the transmission mode

2.4
Broadcast Transmission Mode
It is possible to send data by broadcast transmission. Broadcast transmission mode can be used by setting the
destination address to “255” at packet transmission or headerless packet.
In broadcast transmission mode, the sender FDP02 transmits data packet defined times by REG11 register + 1
time. If "Enabling response" function is turned on, the sender FDP02 sends response signal to the host. For
more details, see the section 2.1.
At broadcast transmission mode, the receiver FDP02 does not return ACK signal regardless of the REG18
register setting. Also, when the receiver FDP02 receives redundant data packet, it ignores duplicated
packets .
The below figure shows the data flow of broadcast transmission mode that "Enabling response" and
"Returning P0 and P1 responses" functions of the sender FDP02 is turned on.
① Host 1 inputs broadcast data to the sender FDP02.
② The sender FDP02 recognized the data packet configuration is valid and returns a P1 response to the host 1
(data is accepted).
③ The sender FDP02 broadcasts data packet defined times by REG11 register + 1 by air .
④ When the receiver FDP02 receives the packet correctly, it outputs the received data packet to the host 2 via
the serial port.
⑤ When the sender FDP02 completes all data transmission, it outputs a P0 response to the host 1.

3. Transmission Timing
3.1
Transmission Timing
At packet transmission mode, the FDP02 can transmit up to 130 bytes of message as a single packet.
However, the radio transmission unit of the data is divided by 26 bytes. Since the FDP02 internally divides a
message by 26 bytes when the packet size is bigger than 26 bytes, total data transmission time is varies with
the data size. .
In headerless packet transmission mode, the FDP02 transmits each message in units of 26 bytes without
dividing them.
The time required for communication is shown below.

① Serial input of transmission data packet
The time required to data input between the host1 and the sender FDP02 is defined by below
communication parameter.
- Line speed (9,600 to 115,200 bps)
- Data bit length (7 or 8 bits)
- Parity bit (odd, even, or no parity)
- Stop bit length (1 or 2 bits)
- Start bit length (always 1 bit)
For example, data transmission time is 87us when the line speed is 115,200bps, the data bit length is 8 bits,
the parity bit is NONE, the stop bit length is 1 and the start bit length is 1. (Time of data transmission for
1 bit is 8.7us and 1byte is 10bits.)
If the transmission is text data at the packet transmission mode, size of send data packet is message bytes +
9 bytes because the header is 7 bytes and delimiter is 2 bytes.
If the transmission is binary data at the packet transmission mode, size of send data packet is message
bytes + 12 bytes because the header is 10 bytes and delimiter is 2 bytes.
At the headerless packet mode, the data size is message bytes + 2 bytes if delimiter is included. On the
other hand, if the trigger of transmission is “time-out”, the data size is the same as the message size.
However, the data transmission time is defined by “time-out” setting by REG24 and REG26 register.
② C ommand processing
It is the time for internal processing to of receiving and decoding the packet that comes from the serial port.
It takes 1.5 ms.
③ T ransmission packet generation
It is the time for transmission data packet generation. It takes 1.0 ms.
④ Response of input data format acceptance
It is the time for response when the receiving data format is valid.
the parameters of ①.
The length is 4 bytes. It depends on
⑤ Carrier sensing
It is the time for detection whether other radio station uses same frequency band. If other radio station
uses the frequency band, the sender FDP02 does not transmits the data. It takes 0.1 ms.
If the wireless environment is very severe, noise level is very high and/or other
wireless systems occupy the area, the sender FDP02 may be not able to transmit
any data because of carrier sensing.
⑥ Message transmission
It is the time for data transmission and it takes 0.45 ms.
⑦ Dat a reception processing
It is the time for the receiving data processing and it takes 2.4 ms.
Ver.1.1
⑧ ACK packet generation
It is time for ACK packet generation. It takes 1.0 ms
⑨ ACK packet transmission
It is time for ACK packet transmission that the acknowledgement of data packet reception. It takes 0.45
ms.
⑩ ACK reception processing
It is processing time for ACK packet. It takes 1.0ms.
⑪ Serial output of received packet
It is time for output of received data packet to the host 2 through the serial port.
on the communication setting between the host 2 and the receiver FDP02.
The time period depends
If the transmission is text data at the packet transmission mode, size of output data packet is message bytes
+ 8 bytes because the header is 6 bytes and delimiter is 2 bytes. If the transmission is binary data at the
packet transmission mode, size of send data packet is message bytes + 11 bytes because the header is 9
bytes and delimiter is 2 bytes.
At the headerless packet mode, the data size is message bytes + 2 bytes if delimiter is included. On the
other hand, if the trigger of transmission is “time-out”, the data size is the same as the message size. If
"Adding '' to received data" function of the receiver FDP02 is turned on by the bit 4 of REG23
(setting value is 1) at the headerless transmission mode, "" is added at the end of the data and it
consume 2 bytes.
⑫ Indication of data transmit completion
A response is returned to the host 1when the data transmission is completed correctly. The length of
response data is 4 bytes, and the time period of response return depends on the parameter settings of the
communication parameters that are described in above section ①.
Based on the above data processing flow, the total time for the data packet transmission from the host 1 to the
host 2 can be calculated like below. (In the below calculation, no data packet re-transmission is supposed.)

3.2
Time period of the case that data re-transmission of divided packet is occurred at packet
transmission mode
When packet data size is exceeding 26 bytes, it is divided into several packets that data size is 26 bytes. At
that time, each divided packet is sent defined re-transmission times. Thus, maximum data transmission
period will be (setting of REG11 register + 1) x 5 times. (REG11 register is a parameter of data
re-transmission frequency.)
It takes 3.7 ms if data transmission failure is occurred once. Therefore, total data processing time is like
below formula.

B: Trigger of the data transmission is time-out at headerless packet transmission mode:
"Value of REG26" x 10
Others:
In this case, if data transmission failure is occurred in any given
divided packet, following packets are not transmitted. Therefore,
total data transmission period is fluctuated.
Example 1: At the line speed set to 115,200 bps and bit length per byte set to 10 bits, time period of the data
transmission failure detection is 53.1 ms if the first packet data is fail to transmit. (Size of the
message is 130 bytes. Setting of data re-transmission frequency is 10 times.)
(1
0/115,200) × 1,000 × (130 + 9 + 4) + 7.3 × (10+1) × 1 = 92.7 [ms]
Example 2: At the line speed set to 115,200 bps and bit length per byte set to 10 bits, time period of the data
transmission failure detection is 215.9 ms if the fifth packet data is fail to transmit. (Size of the
message is 130 bytes. Setting of data re-transmission frequency is 10 times.)
(1
0/115,200) × 1,000 × (130 + 9 + 4) + 7.3 × (10 + 1) × 5 = 413.9 [ms]
As shown above, the total transmission time is largely fluctuated by the condition of the data transmission.
To keep communication response well, size of the message should be less than 26 bytes.

Explanation of Registers
REG00 (local station address) [Defau
lt: 00H]
This register can set own wireless address. When the FDP02 receives a packet that destination is this
address, the FDP02 processes the packet. The setting range is 00H to EFH (000 to 239). If the value is
set to invalid range, the FDP02 returns N0 response.
REG01 (group address)
[Default: F0H]
This is the wireless group address of the FDP02. When the FDP02 receives a packet that group is this
address, the FDP02 processes the packet.
If "Enabling destination address check at reception" function of the REG18 is turned on, the FDP02 returns
ACK signal to sender FDP02 when it receives a packet. Therefore, if "Enabling destination address check
at reception" function of all FDP02 in the system is turned on, all FDP02 that receive a packet return ACK
signal. Thus, to avoid unnecessary communication, the REG18 may be set to "Disabling destination
address check at reception".
The range of the setting value is F0H to FEH (240 to 254). If the value is set to invalid range, the FDP02
returns N0 response.
REG02 (headerless-packet destination address) (only for the headerless packet transmission mode)
[Default: 00H]
This register indicates the destination address of packet data in headerless packet transmission mode. This
register also indicates the wireless address of the connection destination when TS2 command is used.
The range of the setting value is 00H to FFH (000 to 255). If the value is set to invalid range, the FDP02
returns N0 response.
REG03 (transmission mode)
[Default: F0H]
This register setting can change the transmission mode, which is packet transmission mode or headerless
packet transmission mode.
F0H
Packet transmission mode (default)
FFH
Headerless packet transmission mode
The value of the setting is F0H (packet transmission mode) or FFH (headerless packet transmission mode).
If the value is set to invalid range, the FDP02 returns N0 response.
REG04 (ID code 1)
[Default: 00H]
This register setting defines data scramble ID. Combined with ID code 2 (REG05), variation of data
scramble ID is up to 65,536.
Range of the setting value is 00H to FFH and FDP02 returns N0 response if the value is out of the range.
The same scramble code (REG04 and REG05) must be set on all the
FDP02s in the system. If the scramble codes are different each other,
each FDP02 cannot communicate with.
16
Ver.1.1
REG05 (ID code 2)
[Default: 00H]
This register setting defines data scramble ID. Combined with ID code 1 (REG04), variation of data
scramble ID is up to 65,536.
Range of the setting value is 00H to FFH and FDP02 returns N0 response if the value is out of the range.
The same scramble code (REG04 and REG05) must be set on all the
FDP02s in the system. If the scramble codes are different each other,
each FDP02 cannot communicate with.
REG06 (frequency group)
This register defines the number of frequencies to be used.
01H
Use only the frequency set by REG07
02H
Use the frequencies set by REG07 and REG08
03H
Use the frequencies set by REG07 to REG09 (default)
[Default: 03H]
The range of settings is 01H to 03H.
When the register is set to 01H, only a frequency that is set by REG07 is used.
When the register is set to 02H, two frequencies that are set by REG07 and REG08 are used as a frequency
group.
When the register is set to 03H, three frequencies that are set by REG07 to REG09 are used as a frequency
group.
FDP02 returns N0 response if the value is out of the range.
The setting value of REG07, REG08 and REG09 should not be
duplicated when the setting of REG06 is “02H” and “03H”. If the
frequencies have duplication, the transmission frequency will not be
switched.
REG07 (frequency 1)
[Default: 02H]
This register defines the frequency channel to be used for radio communication. The frequency channel

Enabling N0 response (default)
Disabling N0 response
Bit 2 is available only if the bit 0 is set to "Enabling response."
If this bit is set to “0” (Enabling N0 response), the FDP02 sends N0 response to the host thorough the serial port
when the packet data format from the host is invalid or time gap between bytes is more than 5 seconds.
If this bit is set to “1”, the FDP02 does not send any N0 response to the host
When the bit2 of REG13 is set to “1”, the FDP02 does not send any
response even if the packet format is invalid.
Bit 1: Normal response

Returning P0 response
Bit 1 is available only if the bit 0 is set to "Enabling response." By this setting, it is possible to select type
of response when the data packet configuration is valid.
If the bit 1 is set to “0”, the FDP02 sends P1 response to the host through the serial port when it receives a
data packet. Also, it sends P0 response to the host when the data transmission to the receiver is success.
When the data transmission to the receiver is failed, the FDP02 sends N1 response to the host.
If the bit 1 is set to “1”, the FDP02 sends P0 response to the host through the serial port when the data
transmission to the receiver is success and sends N1 response when the data transmission to the receiver is
failed.

[Default: 00H]
If the packet to be transmitted in headerless packet transmission mode includes code "40H", which indicates
the command header (@), the data following the code is handled as a command, and the packet cannot be
transmitted normally. This register is used to avoid such problems. Code "40H" is handled as the
command header only when the code is input after a time gap between bytes that exceeds the value set in
this register.
The range of settings is 00H to FFH. The value is in units of 100 ms.
With the default setting (00H) of this register, code "40H" is always handled as the command header.

RST
[Response]
P0: Norm al end
N0: Co mmand error
[Function]
- This command has the following two functions:
(1) If values of the memory registers are changed before this command is executed, new register settings
are registered by this command execution. However, values that are changed by “DAS”, “FUN”
and “FRQ” command are vanished and the settings of memory registers are effective.
(2) This command also makes the FDP02 exit from the line quality test of the “TS2” command. When
this command is executed for exit from the line quality test, the memory register settings that are
made before execution of the TS2 command are not saved.
[Example of use]
>@RST:
:
This command resets the FDP02.
This response indicates the normal end of command processing.
The host cannot receive any response from the FDP02 if
communication parameters such as baud rate are different from default
setting.
It will take 520ms at maximum for P0 response of this command.
Memory registers may get damages if the power of FDP02 is turned
off before the P0 response comes back.

[Function]
- This command transmits binary data.
- The length of message can be defined from 0 to 130 bytes arbitrary.
- To broadcast data to multiple radio modems, “destination address” should be defined to “255”. At this
setting, the sender FDP02 transmits data packet “re-transmission frequency” that is defined by REG11 + 1
times and then returns P1 and/or P0 response to the host according to the REG13 setting.
[Examples of use]

The delimiter of this command should be “”. It becomes command
error if different delimiter is added.
At broadcast transmission mode, the sender FDP02 cannot recognize whether
receiver FDP02s receive the transmitted data or not.
Do NOT execute next command before the sender FDP02 receives P0 response.
If the setting is "Disabling response" and no P0 response is sent to the sender
FDP02, please wait expected P0 response time before executing next command.
If next command is executed before P0 response, command error is occurred and
the system might have unexpected movement.

[Function]
- The communication line quality test is executed by this command. At the test, one data packet has 32
bytes and one hundred packets are exchanged as a test unit between the “master” FDP02 and the
“slave” FDP02. The test results are output to the serial port.
- The test result is shown by “o” and “x” for each packet. “o” indicates that it is no communication
error and “x” indicates that communication error is occurred.
- When this command is executed at the “master” FDP02, the “master” tries to connect the “slave”
FDP02 that wireless address is defined by REG02 of the “master”. At that time, operation mode of the
“slave” is automatically changed to TS2 communication line quality test mode.
- Both the “master” and the “slave” output the test result.
- Total error occurrence of the test is indicated in 3 digits number after 100 of “o” ”x” judgments.
- If consecutive 1,000 packets become communication error, the line is disconnected. After the
disconnection, the “master” continues to request wireless connection but the “slave” abort from TS2 test
mode.
- During this TS2 test mode, all the commands except for “FUN”, “FRQ” and “RST” command are do
not work. For abort from TS2 test mode, it is needed to execute “RST” command or turned off the
main power of the FDP02. When the “master” aborts from TS2 test mode, the “slave” automatically
stops the test mode and returns to normal operation mode.
[Example of use]

[Function]
- This command orders the FDP02 to transmit text data.
- The length of message can be defined from 0 to 130 bytes and a delimiter indicates the end of message
data.
- To broadcast data to multiple radio modems, “destination address” should be defined to “255”. At this
setting, the sender FDP02 transmits data packet “re-transmission frequency” that is defined by REG11 + 1
times and then returns P1 and/or P0 response to the host according to the REG13 setting.
[Examples of use]

The length of message should be not more than 130 bytes. It becomes
command error if the length of message exceeds 130 bytes.
If the message includes "," the FDP02 is recognizes that it is the
end of the message and it ignores following message. Thus, “TBN”
command should be used instead of “TXT” command if the message
contains “”.
At broadcast transmission mode, the sender FDP02 cannot recognize
whether receiver FDP02s receive the transmitted data or not.

Vcc:
Power supply pin. Connect a power source and the voltage range is from 2.5 to 5.5 VDC.
RXD: Data output pin that is the DCE compliant
TXD: Data input pin that is the DCE compliant
CTS: Hardware flow control output pin that is the DCE compliant (Hardware flow control is enabled
when the signal is high level.)
RTS:
Hardware flow control input pin that is the DCE compliant (Hardware flow control is enabled
when the signal is high level.)
/INI:
Parameter initialization pin. Leave this pin unconnected when it is not used. To initialize the
registers, set the /INI pin to low level at power-on or combine the operation of this pin with the
operation of the /SHUT pin. After the registers (parameters) are initialized, the DP01 operates in
normal mode.
/SHUT: Power-off pin. When this pin is set to low level, the main power of the FDP02 is cut and becomes
“power-down” mode. When the setting of this pin is high level, the FDP02 is in normal operation
mode.
TEST: Test pin. Do NOT use this pin. This pin is only for maintenance by the manufacturer.
GND: Ground pin
Parameter setting of the register will be vanished if the /SHUT pin
becomes low level and the operation mode becomes “power-down”
mode. Therefore, DO NOT connect /SHUT pin during REG
command setting.
After releasing from the power-down mode, parameter settings of
registers that were changed by commands will be initialized. Thus,
the parameter settings should be done by the memory registers when
the “power-down” mode is used or set the parameters again after
returning from the “power-down” mode.
It will take 90 ms at the maximum to return from the “power-down”
mode to normal operation mode.

Notes
Data Communication Delay
It will take certain time to synchronize when the frequency group setting is 2 frequency channel mode or 3
frequency channel mode.
11.1.1 Delay at the transmission side
(1) Delay due to the number of frequency channels in use
When the setting of the FDP02 is 2 frequency channel mode and/or 3 frequency mode, the FDP02
changes the data transmission frequency channel as every data re-transmission. It takes 7.6 ms to
re-transmit a data packet for packet generation, carrier sensing and waiting ACK time-out. Thus, the
data communication will be delay when the setting of the FDP02 is 2 frequency channel mode and/or 3
frequency mode.
(2) Delay due to carrier sensing
If the FDP02 detects radio wave that is same frequency channel as own use, the FDP02 switches the
carrier frequency channel to another. It is called “carrier sensing” and takes 7.6 ms. Thus, the data
communication will be delayed if other wireless systems such as WiFi in the same area.
11.1.2 Delay at the reception side
(1) Delay due to extension of reception-wait time
The FDP02 extends reception-wait time according to the frequency it has received. The extended
reception-wait time depends on the on the number of frequencies in the frequency group, which is "10+5
x (number of frequencies in the frequency group)2" ms. Since the FDP02 keeps the same frequency
during the extended reception-wait time, the extension of reception-wait time may cause a delay in
communication in an environment with much noise or jamming.
11.2
Reception of Same Packets
The FDP02 can store five packets of received data in the reception data buffer. However, when it receives
more than 5 packets, the FDP02 deletes the data packet from the oldest data one after the other. For example,
if the local FDP02 receives data packets from six remote FDP02s at the same time, one of the received data
packet is eliminated. Therefore, when the FDP02 receives a data packet that is same as the eliminated one,
the FDP02 cannot realize the duplication of the data packet and output the data to the host. It will happen
when the FDP02 is used in below listed condition.
(1) More than seven or more FDP02s operate at the same time in the system.
(2) Data re-transmission is frequent.
(3) The data packets having the same packet size are transmitted.
Even if the local FDP02 cannot receive the ACK signal of a packet from the remote FDP02, the remote FDP02
may success to received the packet.
11.3
Timing of Command Input
Do NOT execute next command before the sender FDP02 receives P0 response. If the setting is "Disabling
response" and no P0 response is sent to the sender FDP02, please wait expected P0 response time before
executing next command. If next command is executed before P0 response, command error is occurred and
the system might have unexpected movement.
When "Disabling response" is defined, the command should be executed after waiting the specific time that is
defined by REG15.

Ver.1.1
11.4
Headerless Packet Transmission Mode
11.4.1 Input data
In headerless packet transmission mode, up to 150 bytes of message can be stored in the transmission buffer,
and transmission starts when the total length of the messages stored in the message buffer exceeds 26 bytes.
If many messages are input successively, the message buffer may become full because wireless transmission
cannot keep pace with message input, and some messages may be lost. If such an event occurs, enable the
hardware flow control. You are recommended to specify "Enabling response" also in headerless packet
transmission mode since, with this setting, you can confirm the success or failure in message transmission with
each response.
11.4.2 Measures against packet loss
(1) Messages exceeding 26 bytes
If messages not less than 26 bytes in total are input successively, transmission of some messages input
earlier may fail. To prepare for such an event, check each response on the sender FDP02 to prevent the
loss of messages, and create messages so that the loss of packets can be determined on the receiver
FDP02.
(2) Setting of serial communication speed
If different serial communication speeds are set on the sender FDP02 and the receiver FDP02, the loss of
data may occur on the FDP02 configured with a slower speed than that of the other FDP02. Therefore,
you are recommended to set the same serial communication speed on all FDP02s.
11.5
Occurrence of Data Loss Even under Hardware Flow Control
If the FDP02 is connected to a personal computer and a specific software program created on the personal
computer is used, the data output from the personal computer to the FDP02 does not stop immediately even
when the input to the FDP02 is disabled by hardware flow control. In such cases, the data output from the
personal computer may be lost.
11.6
Frequency Setting in Multi-System Environment
If multiple FDP02 systems are operating, set the radio frequencies that are apart from each other at least by 2
MHz on individual FDP02s. If adjacent communication channels are set on different FDP02s, interference
may occur and disable the FDP02s to communicate.
11.7
Timing of Command Input
When entering multiple commands successively, wait, after entering a command, until the P0 response for the
entered command is received before entering the next command. If the next command is entered before the
P0 response for the preceding command is received, an error occurs or the entered next command is ignored.
11.8
INI and RST Commands
After executing the INI or RST command, always check that the P0 response is returned. Turning off the
power of the FDP02 before the P0 response is returned may damage memory registers. If the return of P0
response cannot be checked, for example, in case that the baud rate has been initialized, wait for 520 ms or
more after entering the INI or RST command, and then turn off the power.
11.9
Power-Down Mode
Switching the FDP02 to the power-down mode (by setting the /SHUT pin to the low level) while registers of
the FDP02 are being accessed may delete the settings in the registers. To avoid this problem, do not control
the /SHUT pin while the REG command is being executed.
Releasing the FDP02 from the power-down mode clears the parameter settings in registers that were made
with commands before the FDP02 was set into the power-down mode. Change the parameter settings before
using the power-down mode, or make the parameter settings again after releasing the FDP02 from the
power-down mode.
The FDP02 returns to the normal operation in a maximum of 120 ms after the FDP02 is released from the
power-down mode.
