p.1FUTABANi04-008-1 rev 4.01. INTRODUCTION1-1. Special Features1 FDK02TU mobile station communicates with the modem FDK01TU fixed station through)() ()coupler FZE02TJ010 and 200-ohm feeder cable.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 andmultiple 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.1-2.

Communication commandInput 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 userdata.Text data @TXT address user data CR LF()( )[][]Address : ASCII code, hexadecimal 3-digits()For instance, 4 is "34h" in ASCII.Data : ASCII code, hexadecimalThe data length : Arbitrary but no more than 1024 bytes.[]CR : 0Dh in hexadecimal[]LF : 0Ah in hexadecimalExample : Sending "ABCDEFG" to a mobile station whose address is 400.@TXT400ABCDEFG CR LF[][]Binary data @TBN address data length user data()( )( )Address : ASCII code, hexadecimal 3-digitsData length : "001" to "400" 0 to 1024 bytes()The number of bytes should be expressed by hexadecimal 3-digits inASCII code.[][]CR LF : not necessaryIf data length is longer than predetermined data length, the surplus of the data will slide infront 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 acharacter 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 thenumber 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
p.11FUTABANi04-008-1 rev 4.0message "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 theheadfirst. In case of @TBN command, the receiver will output the data that is within the range determined bythe 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 upto 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 datathat the sender could properly receive from the external interface of the receiver.7.

This command willbe carried out regardless of the communication status on the feeder.8. AddressThe 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 tothe specific one of the fixed stations that is connected in multi-drop fashion. No specific address isnecessary in case sending data from mobile stations, because there exits only one fixed station.9.
