FRH-SDO6TU Theory of Operation 24 th Mar 2000 Radio Control Equipment Group Futaba Corporation -- Outline FRH-SDO6TU is a 2.4GHz radio modem using modern digital modulation technology. . Data Terminal Equipment (DTE) interface is RS-232C(TTL), best fit for industrial use data communication. Communication speed is from 300bps to 38400bps. Two basic communication mode over the radio link, data transparency mode and packet transmission mode, are available. The data transparency mode acts just like two terminal being connected by wire. No needs to be aware of the existence of the radio link or radio modem. The packet transmission mode uses a command to send a message to specified destination modem. The command can control the packet transmission operation, therefore, N to M terminal multiple communication can be achievable. The system has 24 individual channels to be able to operate among different communication systems in same area without effecting each other. Each channel can be operate at a group mode. Pair of modem communicate on a channel where channel condition is cood. Once conditions goes bad, the modem searches the frequency in the group where condition is good. Each channel allocates in the space of 2MHz. -- Applications Main application of the modem is industrial use data transferring such as Automated Guided Vehicle (AGV), item picking cart system in a warehouse, between CAD terminal and Numeric Controlled (NC) tooling, machine, production line processing schedule and result information etc.. -- Transmission Power The modem peak output power is within the requirements of section 15.249 of the FCC Rules. The modem is already approved under other standard, e.g. RCR-STD33 (Japan). --System circuitry operation (The system diagram figtire is attached) 1 Transmission Path Modulation data generated from control micro processor is fed to modulation processing LSI. This digital signal will be transmission radio signal at lst IF frequency by modulate the local oscillator, in the FSK Modulation directly by the digital signal. The transmission signal goes through the buffer amplifier and transmission power control circuit and is converted at frequency mixer section with lst local signal to 2.4GHz. This 2.4GHz signal is amplified and finally radiated from the antenna. 2 Receive Path Receive path consist of TX/RX common-use antenna circuit and reception-use antenna circuit. These two antenna circuits are configured to be able to use the diversity reception function. Received signal, good reception condition is selected by ihe diversity function, is fed to low noise amplifier. The amplified signal is converted into lst IF. The lst IF signal is again filtered and amplified and fed into FM demodulation IC which operates both 2nd IF amplifier operation and demodulation operation. In the demodulation IC, after the signal is amplified, the signal is lead to the limiting amplifier and is demodulated by the quadrature FM demodulation circuit. 3 Control The microprocessor handles all of the operation include RF control and serial (RS232C) control. Especially, in the RF circuit control, the processing of the microprocessor is mainly PLL frequency sett ing and transmission and receive data generation and control. -2- FRH-SDO6TU TWO-WAY WIRELESS COMMUNICATION SYSTEM Radio Control Equipment Dept., FUTABA Corp.

   6.Measuring Methods 6.1.Transmitter Parameter Tests (§ 15.249 (a)). All transmitter parameter tests were performed at a test-distance of 3 meters in a semi-anechoic room (radiated). During the tests the EUT was rotated all around and the receiving-antenna was raised and lowered from 1 meter to 4 meters to find the maximum levels of emissions. Cables and equipment were placed and moved within the range of position likely to find their maximum emissions. Measurements were made in horizontal and vertical polarization. EUT was operating in transmit mode at the appropriate frequency with its internal modulation. The bandwidth of the emission was measured with a spectrum analyzer. Resolution (RBW) and video bandwidth (VBW) were set to 10 kHz (RBW and VBW) Wooden turntable 70 cm high Test fixture with EUT Semi-anechoic chamber Test distance 3 meter Measuring antenna Spectrum analyzer FCC-ID: AZPFRH-SD06TUTest Report No. 55503-00169 Page 9 of 90 Pages
