HWM-WC1000 TABLE OF CONTENTS INTRODUCTION ------------------------------------------------ .System Overview and Components System Overview Components .Installation .Circuit Description - Main Digital Board - Rx Module - Tx Module .Tune up Procedure .Electrical specification System Overview The products have been developed for quick & stable service to customers in restaurants. HWM-WC1000 consists of RX Module, Main Digital Board, and TX Module. Functionally RX Module receives data from Table Unit, Main Digital Board process the data, and TX Module pages to each Pager by Pocsag protocol Components The basic System component are : l HWM-WC1000 l Antenna l Power Adapter Main Unit Installation Using an enhanced screw above 3M heights, Fix HWM-WC1000 Also HWM-WC1000 needs power cable within 3M for power supply. . 1. Assemble the antenna like “a” in picture 2-1. “b” “a” PICTURE 2-1 2. Connecting the power adapter to power cable, Insert D/C output to D/C port like ‘b’ in picture 2-1. 3. Turn Main Unit power switch on. When power is supplied, power lamp turns on. When Main Unit receives data from Table Unit ( HWM-TT1000 ), RX Lamp turns on. When Main Unit transfers data to Pager, TX Lamp turns on. Technical Circuit Description ( HWM-WC1000 ) 1 Main Logic Board UD1 ( 80C32 ) 80C32 is compatible with 80c51 in pin composition (8bit Micro controller), but 80c32 uses external ROM instead of internal ROM.. It processes data received from 89LV52 of Table Unit & Server Call Unit. All the data is processed by Pocsag Encoding, transferred to Pager Unit by wireless, and transferred to Host Unit by RS-232C. 80C32 use port 0, & port 2 for address bus, and port 0 for data bus. So, port 0 (pin 32~39) is used for being placed above 8bit(A0~A7) of address, and for data bus (D0~D7). Port 2(pin21~280) is used for being placed below 8bit(A8~a15) of address. Also, using 74HC373(Octal 3-state latches) from external, divide data bus and address bus. As clock signal, used for ALE(Address Latch Enable, pin 30) to active high, When interfaced with external memory component, it is used for being placed below address to latch. U1 ( 89LV52 ) Possesses the same characteristics as 80C32, the system, used 2 of RX Main Unit. The transferred data From Table Unit & SCU, divide channel and receive independently. Received data from each channel through error check, and pass DS1609(Dual Port RAM) to transfer to TX 80C32 of HWM-WC1000 UD3 ( M27C512 ) Eprom(Erasable Electrically Programmable Read Only Memory) 27C512 supports UV (Ultra Violet erase) & OTP(One Time Programmable). This is supported 45ns access Time, and had 8 of in/output and 64Kbyte. Main function of Eprom M27C512, input actual program of HWM-WC1000 and operate as external program memory of 80C32. As clock, to active low PSEN(Program Strobe Enable) and read data from external program memory PSEN is printed 2 times in each Machine Cycle, port 0 is used for address in ALE Falling Edge. Also, 8Kbyte internal Rom is inside 8052 but to connect EA(External Access Enable, pin 31) with ground for using 64Kbyte External Program Memory. UD4 ( 62256 ) External Data Memory 62256 has 8 of in/ouput and 32Kbyte as SRAM(Static Random Access Memory). It is used for operating external RAM. Until A 0 ~ A 13, has input address, and until , I/O 7 ~ I/O 0 has 8 data bus. /OE(out Enable) is connected 8052 /RD, and operates when active low. Also, /WE (Write Enable) pin is connected 8052 /WD, and write when active low. All of the work can operate when /CS(Chip Select) low. UD6 ( 8255 ) It calls PPI(Programmable Peripheral Interface), and common in/ output LSI for using with Intel Micro Processor. 8255 has 8bit of in/output port of 3 port(A,B,C), for lack of 80C32 port to easily control in outside. Total 24bit port divide group A(port A, port C 4 ~ C 7 ) and group B(port B, port C 0 ~ C 3 ) to independently setup operating mode( mode0, mode1, mode2). To decide & control print port to using A 0 , A 1 , CS(Chip Select) UD11 ( DS1609 ) DS1609 is 256byte Dual Port RAM, receiving SCU & Table unit data from RX part 89LV52 of HWM- WC1000 are used when transferred to HWM-WC1000-TX part 80C32. Also it use a buffer. It has 2 asynchronous address/data bus. Each port is controlled by /OE(Output Enable, /WE(Write Enable), /CE(Port Enable). AD 0 ~ AD 7 are Port address/data. UD7 ( 93C66 ) E 2 PROM 93C66 has 255~word*16bit. This is for when power is off, saving information before power off and initial information. Can read & write data anytime by electrical signal, CS means Chip Select Input, SK means Serial Clock Input, DI means Serial Data Input, DO means Serial Data Output. UD9 ( MAX-232 ) This component is for communicating with Host Unit & RS232C. It can change 5V Digital Level to 12V RS 232C or reverse it. UD5 ( 74HC138 ) 74HC138 is Memory Decoder/Demultiplexer CMOS, for expanding lack port of 80C32 to use 80C32 address and generating CE(Chip Enable) signal to control in/output data of 8255, 62256 or DS1609. It controls active low Output(Y 0 ~ Y 7 ) by A 0 ~ A 2 3bit Input. The condition is Chip Enable Pin CS 1 High, and CS 2 & CS 3 Low. UD2 ( 74HC373 ) When it interfaces External Memory, controlled signal of address bus is needed, data bus, /RD and /WR, From 80C32, port0, port2 are used address bus, to need port 0 for data bus But, 80C32 port 0 used together address bus & data bus so, to use 74HC373 (Octal 3-state Latch) from outside, and latch printing address before data. Finally, can use dividing address & data. That time clock signal use ALE. . D 0 ~ D 7 are Data Input, Q 0 ~ Q 7 are Non-Inverting Output 2 RX Unit LNA The frequency from antenna only pass range of saw filter F1(DF430)-430MHz +/-4MHz and amplify gain from LNA circuit Q7,Q8 L1,C3,R1,C4. Local Circuit ( PLL Synthesizer , Data Modulation .Loop ) PLL is consists of 3 parts, from Main Board UD1, frequency data input to PLL IC 11,12 and 13 pin. PLL IC is received frequency from reference crystal (X1) 12.8MHz and divided 12.5KHz by reference…

EUT DESCRIPTION The Expeditor is a fully programmable messaging system designed for the restaurant industry. The Expeditor can manage all communication traffic between the kitchen, servers, and guests. This system allows guests to send a specific request to the server just by pressing the button on their table unit. The chef unit feature enables the kitchen to page the server when an order is ready for pick up, saving the server unnecessary trips to the kitchen and insuring that the food is served fast and hot every time. The system keeps the service smooth and efficient, keeps the guest satisfied, and increases also table turnover. The basic system comes with built-in UHF transmitter that provides a superior coverage area (approximately 5,000 to 7,000 square feet). It is composed of 50 individual table messaging units, 10 server’s mobile units, one central processing unit, and one chef unit. 3. TEST METHODOLOGY Both conducted and radiated testing were performed according to the procedures documented on chapter 13 of ANSI C63.4 and FCC CFR 47 2.1046, 2.1047, 2.1049, 2.1051, 2.1053, 2.1055 and 2.1057. 4. TEST FACILITY The open area test sites and conducted measurement facilities used to collect the radiated data are located at 561F Monterey Road, Morgan Hill, California, USA. The sites are constructed in conformance with the requirements of ANSI C63.7, ANSI C63.4 and …
