ARM804 Operation Principle 1. CPU, U6, 88W8500 have a 32-bit RISC processor integrated, operation frequency is 132MHz. It needs an external 44MHz crystal for reference frequency; this crystal is also used for RF module. This chip is responsible to control RF-Baseband Transceiver (88W8000), Flash IC and LED. This chip also has MII interface integrated to communicate with 10/100 Ethernet Switch. 2. FLASH, U13, AM29LV800BT-70EC, 8Mbits Flash, bottom sector, 70ns. It is used to store the normal and test firmware. 3. Integrated 2.4GHz ISM Band RF-Baseband Transceiver, U9, 88W8000 which is integrated all RF-Baseband receive and Transmit function. On-Chip Power Amplifier (PA) with up to +20 dBm output power at the antenna port. It is also integrated programmable frequency synthesizers with integrated VCOs, I/Q generation and CMOS up/down conversion mixers. 4. 10/100 Ethernet Switch, U10, 88E6060 support automatic MDI/MDIX crossover for 100BASE-TX and 10 BASE-T ports. Port 5 has dedicated, always on, MAC Mode (Forward) and PHY Mode (Reverse) RMII/MII/SNI interface for management and firewall applications. Each port works at 10Mbps or 100Mbp, full-duplex or half-duplex mode (forced or auto-negotiated). Flexible LED support for Link, Speed, Duplex Mode, Collision, and TX/RX Activities. 5. Power part: there are several regulators are used on the board. U18, AP34063 is used to transfer DC12V to DC3V3; U1, U8 and U12 AME8805 are used to transfer DC3V3 to DC2V5; U20, 1117-ADJ is used to transfer DC3V3 to DC1V8. The core of CPU is operate at 1.5V. 6. LED part: LED Color Controlled byDescription Amber (Test) FW On - Error condition. Off - Normal operation Blinking - This LED blinks during start up/ Upgrade F/W Power/Test (Double color LED) Green (Power) F/W (TI CPU use H/W) On – System booting complete and then turn it on Amber (10) HW On - Link at 10Mbps Blinking – receiving/ transmitting data LAN (Double color LED) Green (100) HW On - Link at 100Mbps Blinking – receiving/ transmitting data Amber (10) HW On - Link at 10Mbps Blinking – receiving/ transmitting data Internet (Double color LED) Green (100) HW On - Link at 100Mbps Blinking – receiving/ transmitting data WLAN Green FW On - Wireless connection available; Wireless Access Point is ready for use. Off - No Wireless connection available. Blinking - Data is transmitted or received via the Wireless access point. This includes "network traffic" as well as user data. 7. Switch button, SW1, it is used to reset the 88W8500. 8. 9.

ETC Report No. : ET92R-09-079-03 Sheet 25 of 32Sheets FCC ID.: MQ4ARM804 Rev. No 2.0 8 OUTPUT POWER MEASUREMENT 8.1 Standard Applicable For direct sequence system, according to 15.247(b), the maximum peak output power of the transmitter shall not exceed 1 Watt. If transmitting antennas of directional gain greater than 6 dBi are used, the power shall be reduced by the amount in dB that the directional gain of the antenna exceeds 6 dBi. 8.2 Measurement Procedure 1. Check the calibration of the measuring instrument using either an internal calibrator or a known signal from an external generator. 2. Position the EUT as shown in figure 5 without connection to measurement instrument. Turn on the EUT and connect its antenna terminal to measurement instrument via a low loss cable. Then set it to any one measured frequency within its operating range and make sure the instrument is operated in its linear range. 3. Set RBW of spectrum analyzer to 1 MHz and VBW to 1 MHz. 4. Use channel power function and record the level displayed. 5. Repeat above procedures until all frequencies measured were complete. Figure 5: Output power and measurement configuration.
