through communicates with the modem FDK01TU fixed station FDK02TU mobile station coupler FZE02TJ010 and 200-ohm feeder cable. Communication speed is 100Kbps across the feeder wires. FDK has a function to carry out error correction by the combination of ARQ Automatic Retransmission Request 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. 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. and FEC of BCH 15,7 .

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

: 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 character by recognizing backspace key while the binary data method treats backspace key as data. input through terminal software, the text data method can delete a 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 FUTABA p.10 Ni04-008-1 rev 4.0
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.

) This command restarts the exerciser program from the start address. Also the SRAM register will be reset to the condition when this modem was turned on. In addition, this command will initialize not only the software but also the hardware of this modem. It takes about 300ms. After the completion of initialization, a response message of "OK" will be returned to the host computer.

) Timing of command execution Receiving a command from external I/F, the mobile terminal will carry out the command and return its end message immediately after the disconnection of the coupler is completed. This command will be carried out regardless of the communication status on the feeder. 8. Address The effective addresses for mobile stations are from 400 trough 9FF. 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 is connected in multi-drop fashion. No specific address is necessary in case sending data from mobile stations, because there exits only one fixed station. 9. Communication with mobile stations Communication procedure
) an example
Set parameters of fixed station, and make it effective to communicate with mobile stations. Connect to the power source. Connect to the matching/distributing unit. Connect the external interface One of RS-232C, RS422 and RS485 can be changed freely.
) The order between and
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
