多个 T2550 自治控制系统互相之间连接到 100Mbps 的新型高速 ELIN 网，其主要特点是摒弃传统的扩展机座层的概念，在这先进的系统中每一个机座都安装上一个集合控制和通讯于一身的“自治控制器 CPU” ，它的主要功能是自行独立处理从现场检测回来的信号、决策并执行控制策略任务，对本身机座上所有 I/O 做出快速响应。

此外，每台“自治控制器”都支持对等通讯，所以它们之间都能互相通讯和协调控制策略。

由于这一特殊的功能，在一个大型的控制系统中，由这些“自治控制器”组成的系统就能发挥前所未见的优点。

假设在这大型的控制系统中有局部的设备或者控制器等发生故障时，整体系统仍可继续工作，通过控制系统适当态配置，把整个系统分划为多个控制区，在局部发生故障的时候，系统可立刻自动重组，实现容错控制，在众多的 DCS 系统中，更显得出类拔萃。

ISD2560语音芯片的引脚及功能介绍

ＩＳＤ２５６０语音芯片的引脚及功能介绍ＩＳＤ２５６０是ＩＳＤ系列单片语音录放集成电路的一种。

这是一种永久记忆型语音录放电路，录音时间为６０ｓ，可重复录放１０万次。

该芯片采用多电平直接模拟量存储专利技术，每个采样值可直接存储在片内单个ＥＥＰＲＯＭ单元中，因此能够非常真实、自然地再现语音、音乐、音调和效果声，从而避免了一般固体录音电路因量化和压缩造成的量化噪声和“金属声”。

该器件的采样频率为８．０ｋＨｚ，同一系列的产品采样频率越低录放时间越长但通频带和音质会有所降低。

此外，ＩＳＤ２５６０还省去了Ａ／Ｄ和Ｄ／Ａ转换器。

其集成度较高，内部包括前置放大器、内部时钟、定时器、采样时钟、滤波器、自动增益控制、逻辑控制、模拟收发器、解码器和４８０ｋ字节的ＥＥＰＲＯＭ。

ＩＳＤ２５６０内部ＥＥＰＲＯＭ存储单元均匀分为６００行，有６００个地址单元，每个地址单元指向其中一行，每一个地址单元的地址分辨率为１００ｍｓ。

此外，ＩＳＤ２５６０还具备微控制器所需的控制接口。

通过操纵地址和控制线可完成不同的任务，以实现复杂的信息处理功能，如信息的组合、连接、设定固定的信息段和信息管理等。

ＩＳＤ２５６０可不分段，也可按最小段长为单位来任意组合分段。

１ＩＳＤ２５６０的引脚功能ＩＳＤ２５６０具有２８脚ＳＯＩＣ和２８脚ＰＤＩＰ两种封装形式。

图１所示是其引脚排列。

各引脚的主要功能如下：电源（ＶＣＣＡ，ＶＣＣＤ）：为了最大限度的减小噪声，芯片内部的模拟和数字电路使用不同的电源总线，并且分别引到外封装上。

模拟和数字电源端最好分别走线，并应尽可能在靠近供电端处相连，而去耦电容则应尽量靠近芯片。

地线（ＶＳＳＡ，ＶＳＳＤ）：由于芯片内部使用不同的模拟和数字地线，因此，这两脚最好通过低阻抗通路连接到地。

节电控制（ＰＤ）：该端拉高可使芯片停止工作而进入节电状态。

The heart of each section is a DS2250 microprocessor, U1 or U2. In addition to its internal memory, each µP has a 32K byte external RAM, U12 or U13. Each section also contains a 4K byte dual port RAM (DPR), U3 or U4, which provides the interface to the GETC. A single oscillator, U14 provides clock for both processors. Each processor has a serial port which is converted to RS-232 by U8. Indicator LED’s D1 and D2 are activated by one-shots in U9 as long as they are triggered by the associated processor. A single input bit and a single output bit are available on each processor for I/O. The module has a single RESET button which resets both processors. LOAD/RUN circuits on each processor set op-erating mode. Port 1 and INT0 of both processors are tied together to provide a high speed parallel communication link between the two processors.DS2250 MICROPROCESSORThe microprocessor is a Dallas Semiconductor proprie-tary derivative of the Intel 8031. This special version proc-essor has internal circuitry for a bootstrap loader, terminal interface and internal control of 64K bytes of battery backed up RAM. The RAM can be partitioned into separate code and data spaces, with the code space write protected after code is loaded. An internal bit ECE2 under program control alters the memory map allowing access to all available memory.DUAL PORT RAMU3 and U4 provide the interface to the GETC 8032 processor. The GETC sees U3 and U4 as a single 8K byte memory block, addressed from 0 to 1FFFH. U1 sees U3 on its opposite port as a 4K byte RAM addressed from 0 to 0FFFH and likewise, U2 sees U4 as a 4K byte RAM ad-dressed from 0 to 0FFFH. Thus each 1e processor shares 4K bytes of memory space with the GETC processor, allowing efficient exchange of data. U11-D and U10-D drive the output enable (read) input from the GETC. U10-A, B, and C and U11-A and B drive DPR chip enables from the GETC.Copyright© January 1993, Ericsson GE Mobile Communications Inc.SPECIFICATIONSCurrent Drain80 to 120 ma.Supply Voltage 4.75VDC to 5.25VDCMemory Provided (bytes)64K on board, not backed up.128K in the DS2250’s, battery backed up.8K Dual PortRS-232 Serial Ports2I/O 2 bits input - Diode protected, weakly pulled upinverted before processor2 bits output - Transistor buffered, weakly pulled upopen collector.Oscillator frequency 1.0592 MHzIndicators One RED LED controlled by each DS2250 Dimensions 3.00in. x 7.75in. (board)INTRODUCTIONThe GETC 1e (expansion) module (19D903536P1) pro-vides additional processing power and memory for the G eneral E ectric T runking C ard (GETC) which will allow software growth, and expanded features for the E nhanced D igital A c-cess C ommunication S ystem (EDACS™). The 1e module is supplied standard with EDACS station GETC’s, Downlink GETC’s, CNI GETC’s, SCAT GETC’s, EDACS Site Control-ler GETC’s, Simulcast Control GETC’s, and EDACS Satellite Receiver GETC’s beginning in January 1993. The 1e module is not required, but is compatible with all previous hardware and software releases.The 1e module uses mostly surface mount components and mounts on spacers above the GETC. Electrical connections to the GETC are made by removing U3 from the GETC and plugging the 1e modules 28 pin ribbon cable and connector P1 into the GETC’s socket XU3. A small shield above the 1e module protects it from damage when sliding the GETC drawer in and out.CONNECTOR CHARTConnector DescriptionP11e module interface to the GETCaddress/data bus and powerJ1Allow serial interface to U2 at TTLlevelsJ2RS-232 serial interface to U1J3RS-232 serial interface to U2J4I/O on U1J5I/O on U2Figure 1 - Memory Map For Each DS2250MEMORY MAPLBI-38822LBI-388221ON BOARD RAM U12 AND U13When ECE2 is 0, each processor accesses a 32K RAM at address 8000H to 0FFFFH. These RAM’s are on the 1e module board, not on the DS2250, thus they are not backed up by the DS2250 battery. This memory space is used as temporary scratch pad by the processors. U10-E and U10-F drive the RAM CE (chip enable) pin from bit 15 of the address bus. A low enables the RAM.OSCILLATORU14 is an unbuffered CMOS inverter (HCU04). Here, U14-A functions as a linear gain stage with crystal Y1 in its feedback, forming an oscillator at 11.0592 MHz. U14-B buff-ers the clock and drives both processors.RESETSwitch S1 resets the 1e module and S4 on the GETC resets the GETC. Software will usually start properly with only a GETC reset, however resetting both will work.Depressing switch S1 grounds R21 and R22 and the posi-tive side of C21. This turns on PNP transistors Q4 and Q7 which pulls the RESET input of each processor high, holding them in the RESET condition. When S1 is released, the voltage at C21+ (and Q4 and Q7 bases) slowly rises as C21 charges through R8 and R15. Eventually this voltage rises high enough so Q4 and Q7 turn off and the processor RESET inputs fall low and are held low by R7 and R14. R8 and R15 hold Q4 and Q7 off.LOAD/RUN CIRCUITIn normal RUN mode, the processors RESET input is held low and PSEN is an output which controls external memory. The DS2250 is put into LOAD mode by holding the RESET pin high and the PSEN pin low.Switch S2 controls RUN/LOAD for processor U1. When S2 is down (toward S1) (shorting pins 2 and 3) U1 is in LOAD mode. VCC (5V) is applied to R10 and R12. This turns on Q8 which turns on Q7 through R9 thus pulling U1’s RESET high. VCC on R12 turns on Q6 which holds PSEN low. When S2 is up (shorting pins 1 and 2) the processor is in RUN mode. VCC is not applied to R10 and R12. Q8 is held off by R11 and Q7is held off by R8 so RESET is pulled low by R7. Q6 is held off by R13 so PSEN is not held low and may become an output of U1.Switch S3 controls RUN/LOAD for processor U2. When S3 is down (shorting pins 2 and 3) U2 is in LOAD mode. VCC (5V) is applied to R17 and R19. This turns on Q5 which turns on Q4 through R16 thus pulling U2’s RESET high. VCC on R19 turns on Q3 which holds PSEN low. When S3 is up (shorting pins 1 and 2) the processor is in RUN mode. VCC is not applied to R17 and R19. Q5 is held off by R18 and Q4 is held off by R15 so RESET is pulled low by R14. Q3 is held off by R20 so PSEN is not held low and may become an output of U2.RS-232 INTERFACEThe RS-232 interfaces are used to program the DS2250 modules and to interface to other serial devices (future appli-cations). An Intel Hex format file from a PC can be loaded into memory via the serial ports. Complete instructions will accom-pany software loaded in the field.U8 is a dual TTL to RS-232 duplex serial interface. Ca-pacitors C1, C2, C3, and C4 are used by U8 to convert 5V to RS-232 levels. Section 1 converts U1’s serial port to RS-232 and section 2 converts U2’s serial port to RS-232. Serial output for U1 is J2-1 and input is J2-2. Serial output for U2 is J3-1 and input is J3-2. J1 is inserted in the RXD line of U2 to allow interfacing to U2’s serial port at TTL levels.BIT I/OOne output bit from U1 is available. It is buffered by Q9 and drives out on J4-2. Weak pullup R30 holds J4-2 high when Q9 is turned off by U1. One input bit to U1 is available. It is buffered by U15-A and protected from static and overdrive by D3 and R27. Weak pullup R35 holds the input high when not in use.One output bit from U2 is available. It is buffered by Q10 and drives out on J5-2. Weak pullup R32 holds J5-2 high when Q9 is turned off by U1. One input bit to U2 is available. It is buffered by U15-B and protected from static and overdrive by D4 and R31. Weak pullup R36 holds the input high when notin use.Figure 2 - GETC 1e Block DiagramLBI-38822LBI-38822 2LED INDICATORSLED D1 is controlled by processor U1. The processor must apply pulses to retriggerable one-shot U9-A, pin 4, about every half second or faster to keep the light on. It is used as a visual indication that the software is running. The pulse on U9-4 retriggers the output on U9-6 keeping Q1 on and LED D1 on. If the pulses don’t appear in time, the one-shot times out and U9-6 falls low turning off Q1 and D1. R1 and C17 determine the drop out time.LED D2 is controlled by processor U2. The processor must apply pulses to retriggerable one-shot U9-B, pin 12, about every half second or faster to keep the light on. It is used as a visual indication that the software is running. The pulse on U9-12 retriggers the output on U9-10 keeping Q2 on and LED D2 on. If the pulses don’t appear in time, the one-shot times out and U9-10 falls low turning off Q2 and D2. R4 and C18 determine the drop out time.TROUBLESHOOTINGVery little troubleshooting is possible in the field. Prob-lems may be traced to the 1e module by substituting another 1e module. If it is not known that the substitute module has correct software, either load correct software into it or take the DS2250 modules out of the suspect 1e and put them into the new 1e. If DS2250 modules are substituted, be sure to put U1 from the old 1e into XU1 of the new 1e and likewise for U2. The two processors will generally contain different software.If problems can be traced to the 1e module, here are some things to look for. Visually check for damaged parts, un-soldered pins or parts, broken cable or pins (P1), or unseated DS2250 modules. Look for trash in the SIMM sockets. A magnifying glass or low power microscope is helpful. Make sure S2 and S3 are positioned toward the rear of the GETC in the RUN condition. Make sure the jumper is on J1-1 to 2. Check for 5V 0.25V at C5+. With a high speed, high impedance scope, check for oscillations at U14-4. A somewhat flattened sine wave of about 4V amplitude at 11.0592 Mhz will be seen.PROGRAMMING INSTRUCTIONSLOADING 344A4414G1 SOFTWARE INTOTHE GETC 1e MODULEREQUIRED ITEMS•IBM compatible PC, monitor and keyboard with atleast 640K memory,•Hard disk (recommended but not required) and serialport (COM1)•TQ-3360 programming cable•DB-25 male to DB-9 female adapter or cable (neededif PC COM1 connector is DB-9 male instead of DB-25 male)•Software Distribution diskette 344A4414G1PREPARATIONBefore loading can begin, the files listed below must existon the PC used as the loader. Create a new directory, forinstance, "LOAD1e" with the command "MKDIRLOAD1E". Then change into that directory and copy thefollowing files from the distribution diskette.load1e.exe1etop.hex1ebot.hex1ecrc.hexAlways change to this directory before loading softwareto 1e modules.The executable file "load1e.exe" loads the file"1etop.hex" into the top processor on the 1e module. Thisprocessor is physically in the rear as viewed from the front ofthe GETC and it accesses the top half of GETC RAM memoryspace (1000-1FFF). It is loaded through J2 and J104. Then"load1e.exe" loads file "1ebot.hex" into the bottom proces-sor on the 1e module. This processor is physically in the front,accesses the bottom half of GETC memory (0-FFF) and isserially loaded through J3 and J103. The loader uses file"1ecrc.hex" to check that the file was loaded correctly.This procedure assumes loading will occur after the iemodule is mounted in a GETC and installed in an EDACSstation.LOADING PROCEDURE1.Connect loader cable TQ-3360 from COM1 on thePC to J104 at rear of GETC. A DB-25 male to DB-9female adapter or cable may be required.2.Move S2 and S3 on the 1e module toward the front.If either switch is already positioned to the front,move it to the rear and then back to the front.3.Execute program LOAD1E and follow its instruc-tions. You will be kept informed of execution steps.After the top processor is loaded, move the program-ming cable to J103, then hit a key to load the bottomprocessor.4.When both processors are loaded correctly, thescreen will say "FINISHED - SWITCH S2 AND S3TO THE REAR". Do so and D1 and D2 shouldcome on to indicate code is executing. Unplug theprogramming cable.ERRORSErrors usually mean communications have been lostbetween the PC and the 1e module. If errors occur, checkcables, plugs, and move S2 and S3 to the rear then backtoward the front.Error 1 Did not receive signon banner from DS-2250.Error 2 Did not receive CR-LF from DS-2250.Error 3 Did not receive prompt from DS-2250.Error 4 Did not receive CRC value from DS-2250.Error 5 Did not receive serial number from DS-2250."Cannot open COM1" - COM1 on the PC is non-existentor in use by other software or hardware. A PC re-configu-ration is required."Cannot open ’filename’" - Be sure file exists in theappropriate directory."BAD CRC" - A CRC error means that after loading,memory contents are incorrect or the wrong 1ecrc.hex filewas used. If 1ecrc.hex is the same version shipped withthe software, a 1e module hardware problem is indicated."Wrong serial number-check cables" - If cabling iscorrect, DS-2250 stiks may have been swapped. The fourbyte serial number is printed to the screen to help inrestoring DS-2250’s to their proper locations. The fourbyte serial numbers must be the same for both DS-2250’sexcept that the least significant byte must be an oddnumber for the top DS-2250 and exactly one less for thebottom DS-2250."Illegal serial number" - Serial number is either invalid,was never programmed, or has been erased.*******END OF PROGRAMMING SPEC*******SERIAL NUMBERINGEach DS-2250 contains a unique serial number. Toavoid loading software to the wrong DS-2250, the loaderprogram, 1eload.exe, uses these serial numbers to checkcabling during programming. GETC code will check DS-2250 serial numbers and will not operate if serial numbersare in the wrong location or if the two serial numbers do notcompare correctly.Do not swap DS-2250 stiks in a 1e module or take oneDS-2250 from a 1e and put it in another 1e. It is permissibleto swap DS-2250’s as pairs if the top and bottom positionsare maintained.LBI-38822LBI-388223PARTS LISTSYMBOL PART NUMBER DESCRIPTION— — — CAPACITORS— — — C119A705205P21Tantalum: 22 µf ±20%, 20 VDCW.thruC5C619A702052P14Ceramic: .01 µf ±10%, 50 VDCW.thruC24C1719A705205P19Tantalum: 2.2 µf ±20%, 10 VDCW.andC18C1919A702061P35Ceramic: 30 pf ±5%, 50VDCW.andC20C2119A705205P2Tantalum: 1 µf ±20%, 16 VDCW.— — — — DIODES— — — — D1HP HSMS-T400LEDandD2D319A700053P2Silicon: 2Diode, Fast Recovery, 250 and mA, 70 PIV.D4— — — — JACKS— — — — J122-12-20343Pin; MolexthruJ5J822-10-20919Pin; MolexandJ9— — — — PLUGS— — — — P119B802001P1Header, 14X2; Samtec SpecialSEP-50546-1.7/01— — — TRANSISTORS— — — Q119A700076P2Transistor; NPN, 3904thruQ3,Q5andQ6,Q8thruQ10Q419A700059P2Transistor; PNP, 3906andQ7SYMBOL PART NUMBER DESCRIPTION— — — — RESISTORS— — — — R119B800607P473Metal Film: 47k ohms ±5%, 1/8 w.R219B800607P103Metal Film: 10k ohms ±5, 1/8 w.R319B800607P102Metal Film: 270 ohms ±5%, 1/8 w.R419B800607P473Metal Film: 47k ohms ±5%, 1/8 w.R519B800607P103Metal Film: 10k ohms ±5%, 1/8 w.R619B800607P271Metal Film: 270 ohms ±5%, 1/8 w.R719B800607P102Metal Film: 1k ohms ±5%, 1/8 w.R819B800607P103Metal Film: 10k ohms ±5%, 1/8 w.thruR13R1419B800607P102Metal Film: 1k ohms ±5%, 1/8 w.R1519B800607P103Metal Film: 10k ohms ±5%, 1/8 w.thruR22R2319B800607P105Metal Film: 1M ohm ±5%, 1/8 w.R2419B800607P102Metal Film: 1k ohms ±5%, 1/8 w.R2519B800607P104Metal Film: 100k ohms ±5%, 1/8 w.andR26R2719B800607P101Metal Film: 100 ohms ±5%, 1/8 w.R2819B800607P103Metal Film: 10k ohms ±5%, 1/8 w.andR29R3019B800607P104Metal Film: 100k ohms ±5%, 1/8 w.R3119B800607P101Metal Film: 100 ohms ±5%, 1/8 w.R3219B800607P104Metal Film: 100k ohms ±5%, 1/8 w.R3319B800607P103Metal Film: 10k ohms ±5%, 1/8 w.andR34R3519B800607P104Metal Film: 100k ohms 5%, 1/8 w.andR36— — — — SWITCHES— — — — S119A701324P1SW, PUSHBUTTON.S2ALCO SE1DGPC SW, 2 Position Slide.andS3— —INTEGRATED CIRCUITS— — U1DS2250-64-12Microcontroller SipStik.andU2U3IDT 7134S70J CMOS Dual-Port RAM, 32k (4kX8-Bit).andU4U519A703471P318Octal 3-State Noninverting Transparent and Latch, 74HC573.U6U819A149446P2RS-232 Drivers/Receivers, MAX232A.U9MC514538BDW Multivibrator (Retriggerable,Resettable).U1019A703483P304Hex Inverter, 74HC04AU1119A703483P302Quad 2-Input NAND Gate, 74HC00.GETC 1e MODULE19D903536P1 (344A3912G1, Rev. 0)Issue 1SYMBOL PART NUMBER DESCRIPTION U1219A705981P101Static RAM (SRAM), HM62256A.andU13U1419A703995P2Hex Unbuffered Inverter, 74HCU04.U1519A703483P321Hex Schmitt-Trigger Inverter, 74HC14.— — — — CRYSTALS— — — — Y119A702511G2611.059 MHz.— — — — SOCKETS— — — — XU1AMP 4-382486-0SIMM Socket.andXU2— — — — JUMPERS— — — — P219A702104P1Jumper.BIVAR CI-192-028Insulator (Under Y1).XETEL 42-000967Printed Wire Board.— — — MISCELLANEOUS— — —HARDWARE KIT344A4019G1(1e Installation) 119B802166P1Guard319B201955P9SPC, Thread4N84P13004B6Screw, Machine519A701365P8Washer6N80P13004B6Screw, machine: Pan head;No. 6-32 x 1/4".7N404P13B6Lockwasher, internal tooth: No. 6.84035306P25Washer, Fiber.919J706152P5Strap, Retaining.HARNESS INSTALLATIONHARDWARE KIT19C337712G17160861P33Clip.19A134011P1Screw (wire tie).LBI-38822LBI-38822 4IC DATA MICROCONTROLLER U1/U2DS2250DUAL PORT SRAM U3/U4IDT7134S70J (344A3040P201)OCTAL 3-STATE NONINVERTING TRANSPARENT LATCH U5, U619A703471P318 (74HC573)RS-232 DRIVERS/RECEIVERS U819A149446P2 (MAX232A)MULTIVIBRATOR (Retriggerable, Resettable) U9MC14538BDWHEX INVERTER U1019A703483P304LBI-38822LBI-388225IC DATAQUAD 2-INPUT NAND GATE U11 19A703483P302 (74HC00) STATIC RAM U12, U1319A705981P101 (62256)HEX UNBUFFERED INVERTER U1419A703995P2 (74HCU04)HEX SCHMITT-TRIGGER INVERTER U15 19A703483P321 H(74HC14)LBI-38822LBI-38822 6INSTALLATION INSTRUCTIONSHARNESS ASSEMBLY(19C337712, Sh. 1, Rev. 0)(19D438125, Sh. 3, Rev. 6) LBI-38822LBI-388227OUTLINE DIAGRAM GETC 1e Module(19D903536, Rev. 1)HARNESS(19D904442, Sh. 1, Rev. 0)LBI-38822LBI-388228SCHEMATIC DIAGRAMLBI-38822LBI-38822GETC 1e Module(19D903613, Sh. 1, Rev. 0)9SCHEMATIC DIAGRAMGETC 1e Module(19D903613, Sh. 2, Rev. 0)LBI-38822LBI-38822 10LBI-38822LBI-38822This page intentionally left blank11。

2) 请妥善保管使用手册以备将来参考。

3) 请保持本设备的干燥使其远离潮湿环境。

4) 在将本设备与电源连接前请确认电源电压值并正确地针对7V ~ 30V电压做出调整。

5) 请将电源线置于不会被践踏到的地方并且不要在电源线上堆置任何物件设备要有良好的接电线，避免静电损坏，进行安装前，请先断开电源，否则会损坏主板。

6) 为了避免主板上的元件受到静电的损坏，绝不要把主板直接放到地毯等类似的地方，也要记住在接触主板前使用一个静电手腕带或接触金属通过边缘拿住整块主板安装，切毋接触芯片。

7) 插拔任何扩展卡或内存模块前请将DC电源断开。

8) 不得将任何液体自开口处注入否则会产生严重损坏甚至导致电击。

9) 如果发生以下情况请找技术服务人员处理：✍ 电源线或插头损坏✍ 液体渗入设备内✍ 设备暴露在潮湿的环境中✍ 设备工作不正常或用户不能按照使用手册的指导使其正常工作✍ 设备跌落或受创，有明显的破损迹象注意:如果BIOS电池换置不当会产生爆炸的危险请务必使用同一型号或者相当类型的且为制造商推荐的电池。

3．2 系统内存的安装主板提供2条SO-DIMM 的DDR3 内存插槽，选择安装内存条时，要注意以下几点：✍ 安装时，先对准DDR3L SDRAM 存储条与SO-DIMM 插槽的缺口，用力插到位,再将DDR3L SDRAM条向下并扣入SO-DIMM 插槽，使SO-DIMM 插槽两侧的手柄扣紧并锁住DDR3L SDRAM存储条。

✍ 支持符合1600MHz 规范的DDR3L SO-DIMM内存条。

3．3 跳线设置插图所示JBATE跳线方法。

将跳线帽放置在针脚上时为“短接”；当针脚上未放置跳线帽时，此为“开路”。

插针（JBATE）CMOS状态设定瞬间短接清除CMOS开路正常状态（默认设置）注意：清除CMOS（瞬间短接JBATE位接针）允许您清除COMS里的资料，重置系统参数到默认设置。

在COMS里的资料包括系统设置资讯，例如系统密码，日期，时间及系统设置参数。

您在执行此功能操作前，请先关闭电脑并拔掉电源线，等待十五秒钟之后，用跳线帽瞬间短接JBATE位接针。

插针（JP7）LCD 屏的工作电压设定1-2短接 5 V(默认设置)2-3短接 3 .3 VJP6短接12V注意：在使用LCD 屏前,请先了解其要求的工作电压,再通过改变JP6/7插针的跳线帽状态来选择LCD 屏的工作电压，以确保LCD屏稳定工作。

4.板载接头和接口注意：板载接头和接口不是跳线，切勿将跳线帽放置在这些接头和接口上，将跳线帽放置接头和接口上将会导致主板的永久性损坏！主板提供2个可用的RS232标准串口，用户需要通过（10 芯转9芯）专用转接电缆用来连接具有RS-232标准接口的设备。

如果客户需要串口带电，出厂前可设置5V/12V可选，默认为第9针。

LVDS 显示输出接口(30针LVDS1)下面给出了单/双通道LVDS(18-bit/24-bit)接口定义:LCD背光连接口(INVERTER)用户可根据需要选择使用此接口，用来连接LCD背光设备。
