Special Features
1) FDK01TU ( fixed station) outputs its modulated signals to the 200-ohm feeder cables, demodulates
the modulated signals of a FDK02TU ( mobile station) that come through the feeder cable, and
sends them to FDK01TU's external controllers.
Please note that a matching/distributing unit is necessary to attach one or two 200-ohm feeder cables
to this modem.
2) Communication speed is 100kbps across the feeder wires.
3) FDK has a function to carry out error correction by the combination of ARQ ( Automatic
Retransmission Request) and FEC of BCH ( 15,7).
4) In this system, multiple mobile stations can be allocated to the single feeder cable. And each mobile
station can have individual address that can be set externally. As a result, a single fixed station and
multiple mobile stations can establish a communication network.
5) The interface between the external controller and the fixed station or the one between the external
controller and the mobile stations is designed to meet RS-422, RS-485 and RS232C.

6.SYSTEM OPERATION
6-1. Outline of communication
FDK01TU010 is the wireless modem unit to communicate with FDK02TU010. To send data to FDK02TU010
through serial port( RS-232C, 485, 422) of FDK01TU010, apply command @TXT or @TBN. Refer to the
instruction manual about detail of @TXT or @TBN command. Communications on the air through feeder line
and coupler are performed with packet data transmission mode.
6-2. Preparation of communication on the air
Before making communication on the air with FDK02TU010, it is neccesary to chose frequency and chose the
port of two couplers of transmitter and reciever. The frequency of each FDK01TU010 and FDK02TU010 must
be same.
6-3. Data communication with serial port of the wireless modem
6-3-1.Transmission
To send data to FDK02TU010 through serial port( RS-232C, 485, 422) of FDK01TU010, apply command
@TXT or @TBN. If there was respond ACK from FDK02TU010 on the air, FDK01TU010 make OK output to
its serial port( RS-232C, 485, 422) . If ther was no ACK from FDK02TU010 on the air, then FDK01TU010
make twice retransmission of normal packet on the air. And on third to fifth retransmission, FDK01TU010
transmits BCH mode packet. After all, there was no ACK from FDK02TU010, then FDK01TU010 make NG
output through its serial port( RS-232C, 485, 422) .
6-3-2.Recieving
FDK01TU010 recognise packet mode of FDK02TU010 from which is normal or BCH automatically, then
calculate CRC and make address recognition and make data output through its serial port( RS-232C, 485, 422) .
6-3-3.Data packet format
Data packet format is described below.
Preamble
Header
Data
CRC
Preamble : 32 times repetition of 1 and 0.
Header : address of recipient, and adress of transmitter, nuber of retransumission, nuber of
packet, and so on.
Data
: data to be sent up to 1024 bytes.
CRC
: CRC16 caluculated with Header to Data.
6-3-4.Communication on 1:n mode
One FDK01TU010 able to perform 1:n communication with defined number of FDK02TU010. To make 1:n
communication, define plural address on address part of @TXT or @TBN command. Addresses input through
serial port(RS-232C, 485, 422) of FDK01TU010 will be added to its header.

7. COMMUNICATION WITH MOBILE STATIONS
Communication procedure ( an example)
①
②
③
④
⑤
⑥
⑦
Set parameters of fixed station, and make it effective to communicate with mobile stations.
Connect to the power source.
Connect the external interface ( One of RS-232C, RS422 and RS485)
Connect to the matching/distributing unit.
(The order between ② and ④ can be changed freely.)
Turn on the fixed station and mobile stations.
(The order to turn on the powers is free.)
Wait more than 1 second and then set frequency channel.
After receiving a response of "OK", forward to the next step.
Send command/data in format of @TXT or @TBN.
If "OK" is returned, the communication is completed.
If "NG" is returned, possible reasons of the failure are insufficient signal strength and improper settings of
communication cable, switches and frequencies.
Send @PNG command and read the value of RSSI. If the value is 57 or lager, please confirm the setting
condition again.
If "OK" is returned, it is possible to continue communication by repeating ⑦ .
FUTABA
p.15
Ni04-009-1 rev5.0
8. COMMUNICATION COMMAND
Input and output between external control equipment and mobile stations are carried out by packet method.
The data format of the packet method is either in the sequence of "@TXT ( address) (user data) [CR][LF]"
or in the sequence of "@TBN ( address) (data length) (user data)"
Binary data method is useful to avoid communication errors when a control code matches exactly a part of user
data.
@TXT (address) (user data) [CR][LF]
Text data
Address
Data
The data length
[CR]
[LF]
Example
: ASCII code, hexadecimal 3-digits
(For instance, 4 is "34h" in ASCII.)
: ASCII code, hexadecimal
: Arbitrary but no more than 1024 bytes.
: 0Dh in hexadecimal
: 0Ah in hexadecimal
: Sending "ABCDEFG" to a mobile station whose address is 400.
@TXT400ABCDEFG[ CR][LF]
Binary data
@TBN (address) (data length) (user data)
Address
Data length
[CR][LF]
: ASCII code, hexadecimal 3-digits
: "001" to "400" (0 to 1024 bytes)
The number of bytes should be expressed by hexadecimal 3-digits in ASCII code.
: not necessary
If data length is longer than predetermined data length, the surplus of the data will slide in front of
the next instruction. Therefore "NG[ CR][LF]" may be returned to the data sender.
Example
: Sending 7 bytes of binary data to a mobile station whose address is 400.
@TBN400007 ( 7 bytes of binary data)
Taking into consideration the manual input through terminal software, the text data method can delete a
character by recognizing backspace key while the binary data method treats backspace key as data.
In the communication between the feeder cable and mobile stations, a packet is defined and transmitted as the
number of user bytes that are set by bit2 and bit3 of the DIP SW2.
In the case that transmission and reception of all the data is completed properly, the sender will output the
message "OK [CR][LF]" after receiving ACK of the last packet.
On the other hand, the receiver will output the same character string that was sent from the sender from the
headfirst. In case of @TBN command, the receiver will output the data that is within the range determined by
the user data length, otherwise surplus of the data will not be outputted.
In case of communication error, if ACK is not returned from the destination after repeating retransmission up to
the preset number, the sender will stop sending data and output "NG [ CR][LF]" immediately after detection
of the end of input data.
In case of failure while sending a packet due to communication error, the sender will output the partial data that
the sender could properly receive from the external interface of the receiver.

10. ADDRESS
The effective addresses for the fixed station are from 100 through 1FF while the third digit is always fixed to
"1".
Use rotary switch SW4 for setting.
Set the address at "001" when sending data to the fixed station from mobile stations.
The address setting of the fixed station is required only for the host computer to send control command to the
specific one of the fixed stations that are connected in multi-drop fashion. No specific address is necessary in
case sending data from mobile stations, because there exits only one fixed station.
