Special Features 1FDK02TU mobile station communicates with the modem FDK01TU fixed station through coupler FZE02TJ010 and 200-ohm feeder cable. 2Communication speed is 100Kbps across the feeder wires. 3FDK has a function to carry out error correction by the combination of ARQ Automatic Retransmission Request and FEC of BCH 15,7 . 4In 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. 5The interface between the external controller and the fixed station or the one between the external controller and the m…

1-1 SCOPE This document applies mobile modem system of 200 ohm feeder cable communication system for FUTABA’s customer. 1-2 Communication system and equipment characteristics 1) This system is a mobile middle distance communication system which employs 200 ohm feeder cable as a communication medium. 2) Achieve communication performance that suits the regulation of Part15.209 FCC. Also it complies Japanese very weak radiation radio specification. Furthermore, it complies ETSI 300 220-3 of EU and will be trying to comply Taiwanese radio standard. Other standards are also in the future plan. 3) Feeder communication block contains Auto Repeat Request (ARQ) and Forward Error Collection, BCH (15.7) coding schemes, to improve error robustness. 2 OVERVIEW 2-1 Whole of the system This system is a “non-mechanical-contact”, kind of wireless, communication system which transfers data between mobile station and feeder cable. Feeder cable communication part (block) of the system uses multiplexing signals to single feeder cable both downlink (base station to mobile modem station direction) and uplink ( mobile modem station to base station direction). The frequencys of the uplink, 151MHz to 156MHz are used. Downlink of that is 230MHz to 235MHz. Frequency channel of the each up and downlink is divided into 50 channels and 50 channels are assigned as a physical channel. Communication rate is 100kbps, fixed rate. Data transmission is performed with packet data transmission scheme and both ARQ and error-collection functions are included. On the feeder cable communication part (block), it performs communications not only between base station and mobile modem station but also between mobile modems. Also broadcast communication is possible with limiting cover area using various destination address designation method. External interface between controller and the system, RS232C, RS422 and RS485 are prepared. Communication rate of 4800bps to 115.2kbps can be set. Communication format is packet base communication that is FUTABA’s locally specified standard. Each of the modem displays receiving signal strength on the LED array, therefore, it is easy to confirm operation status and condition of the modem. It is also possible to issue a command from controller. The command requests the modem to reply receiving signal strength and other information of the modem. 2-2 Mobile Modem The mobile modem is a communication radio equipment which is embedded to Automated Guided Vehicle (AGV), i.e. moving cart used in a factory. It is connected with coupling unit (explained below) and is communicate with the base station. External interface between controller and the modem, RS232C, RS422 and RS485 are prepared. Communication scheme between base station and mobile modem station through the feeder is 100kbps fixed speed packet transmission and employs ARQ and error collection of BCH code. 2-3 Coupling unit The coupling unit roles receiver functions which receives signals that leaked from the feeder cable, and transmitter functions which transmits and feed the signals (the output of the mobile modem) to the feeder. Two coupling unit can be equipped to single mobile modem. Switching of the coupling unit is performed by a command from the external controller equipment. 3 SPECIFICATIONS 3-1 Feeder line communication Uplink frequency band 151 to 156MHz Downlink frequency band 230 to 235MHz Bandwidth of one channel 100KHz Channel separation 100KHz # of channels 50 Complies standard Spec A: Japanese very weak radio standard Spec B: FCC Part15.209 Sensitivity -85dBm(100kbps, BER=10E-4) Address setting of mobile modem 201(hex) to 6ff(hex) Communication rate 100kbps Communication mode full duplex packet transmission 3-2 Mobile modem Connector D-sub 9 pin Interface RS232C, RS422, RS485 (Pin assignment is not referred to that of the standard) Communication rate 4800 to 115.2kbps Communication mode RS232C and RS422: full duplex packet transmission RS485 half duplex packet transmission Misc.
