It offers a DVI-D interface with single-link TMDS® and DDC (Display Data Channel) compliance. This converter module can support DVI monitors with resolutions up to UXGA (1600x1200). This converter module is designed for the use with Kontron Embedded Modules GmbH embedded computer boards that support the JILI (JUMPtec Intelligent LVDS Interface) standard. For the support of the complete functionality of DVI (including the DDC support) it is necessary that a video BIOS with DDC auto-detection capability is installed on the embedded computer board. Currently this support is only available for boards equipped with the Intel® chipsets (852/855 or newer). Please contact your technical support for information about available BIOS versions to support this feature.3 Connector Layout 3Connector Layout3.1Top Side3.2Connector Functions and Interface CablesThe table notes connector functions and types.Used Connector DescriptionJ1 DVI Interface MicroCross™ DVI Socket, right angle(Molex 74320-1004)For DVI Monitor cableJ2 LVDS InterfaceFFC 1x40 SG Head2(Hirose FH12-40S-0.5SV)For flat-foil cableJ3 PIC ProgrammingInterface2mm 2x3 pos.

The Bellcore calculation used is “Method 1 Case 1”. In that particular method the components a re assumed to be operating at a 50 % stress level in a 40° C ambient environment and the system is assumed to have not been burned in. Manufacturer’s data has been used wherever possible. The manufacturer’s data, when used, is specified at 50° C, so in tha t sense the following results are slightly conservative. The MTBF values shown below are for a 40° C in an office or telecommunications environment. Higher temperatures and other environmental stresses (extreme altitude, vibration, salt water exposure, etc.) lower MTBF values.Module MTBF (hours) : > 125.0004 Specifications4.5Environmental Specifications4.5.1TemperatureOperating: 0 to +60 C (*) (non-condensing)Non-operating: -10 to +85 C (non-condensing)Note: (*) The maximum operating temperature is the maximum measurabletemperature on any spot on the module’s surface. You must maintain thetemperature according to the above specification.4.5.2HumidityOperating: 10% to 90% (non-condensing)Non-operating: 5% to 95% (non-condensing)5 Getting started5Getting startedGetting started with the ADA-LVDS-DVI adapter is very easy. For location of the connectors, see Chapter 3: Connector Layout. Take the following steps:Turn off the power supply of your system.Connect the 40pin flat-foil cable coming with the adapter to the ADA-LVDS-DVIprinted circuit board.Connect the other side of the flat-foil cable to the JILI connector of your Kontronmodule or to the corresponding base board equipped with a JILI connector.Connect the DVI monitor to the DVI interface connector of the ADA-LVDS-DVI printedcircuit board.Make sure all your connections have been made correctly.Turn on the power of your DVI monitor and of your system.Enter the BIOS of your Kontron Embedded Modules GmbH board and make sure theJILI interface is activated. See the BIOS chapter of the manual for the correspondingboard you are using for details.Note: Only use the 40pin flat-foil cable delivered with the ADA-LVDS-DVI adapter for connection to the JILI connector. This flat-foil cable has its contacts of both cable ends on the same side. A flat-foil cable delivered with another JILI-adapter usually has its contacts on both cable ends on different sides and may damageyour system.6 Chipset6ChipsetThe chipset of the ADA-LVDS-DVI consists of the National DS90CF388 LVDS receiver and the Silicon Image Sil1160CTU PanelLink Transmitter.6.1LVDS Receiver DS90CF388Supports dual-pixel data transmissionUp to UXGA (1600x1200) resolutionComplies with OpenLDI specification for digital display interfaces40 to 112MHz clock supportConverts 8 LVDS data streams into 48bit of digital data (dual pixel 24bit color)6.2PanelLink Transmitter Sil1160CTUHigh Bandwidth (up to 165 MHz)Resolutions up to UXGAFlexible Interface (24bit with 1 pixel/clock or 48bit with 2 pixels/clock)Low Power (3.3V) core operationHigh Jitter ToleranceTransmitter is compliant with DVI 1.07LVDS InterfaceThe LVDS interface functions as an input to the ADA-LVDS-DVI module. It is available through the flat-foil connector J2 (40 pins). You can connect the LVDS interface to your Kontron Embedded Modules board JILI connector via the 40pin flat-foil cable delivered with this adapter.Note: Only use the 40pin flat-foil cable delivered with the ADA-LVDS-DVI adapter for connection to the JILI connector. This flat-foil cable has its contacts of both cable ends on the same side. A flat-foil cable delivered with another JILI-adapter usually has its contacts on both cable ends on different sides and may damageyour system.7.1ConnectorThe following table shows the pin-out of the LVDS connector.Notes: (*) To protect the external power lines of peripheral devices, make sure that:-- the wires have the right diameter to withstand the maximum available current-- the enclosure of the peripheral device fulfils the fire-protecting requirements of-- IEC/EN 60950.7.2Connection Table ADA-LVDS-DVI to JILI interfaceThe following table gives a better understanding about which signal of the LVDS interface corresponds to which signal of the JILI interface. The pin counting is inverted due to the use of the 40pin flat-foil cable with contacts on one side.8DVI InterfaceThe DVI interface functions as an output from the ADA-LVDS-DVI. This interface is available through the female DVI-D connector J1 (24 pins). You can directly connect a DVI monitor with its male connector to this interface. This interface is a single link TMDS® with DDC compliance.8.1ConnectorThe following table shows the pin-out of the DVI connector.Notes: (*) To protect the external power lines of peripheral devices, make sure that:-- the wires have the right diameter to withstand the maximum available current-- the enclosure of the peripheral device fulfils the fire-protecting requirements of-- IEC/EN 60950.8.2DDC and Hot Plug InformationThe ADA-LVDS-DVI is equipped with an onboard microcontroller. After power-on of the system the /HOTPLUG signal of the LVDS interface goes high for about 10ms and the microcontroller is initialized. After initialization the /HOTPLUG signal goes low and the microcontroller will read in the DDC (Display Data Channel) of the connected DVI monitor. This transaction runs with 10kHz by using the signals DDCDAT and DDCCLK and is completed within 500ms. Then /HOTPLUG goes high again. After this transaction is finished the Kontron Embedded Modules GmbH embedded computer board reads the DDC structure from the microcontroller through the DDC signals of the JILI interface (DDC_DAT and DDC_CLK) with up to 100kHz.In case of the system is already powered up and the DVI Monitor is connected later (Hot Plug), the signal HTPGL on the DVI interface goes high and the microcontroller starts reading the DDC from the DVI Monitor. After all of the DDC data is read the /HOTPLUG signal on the LVDS interface goes high and the embedded computer board reads the DDC structure from the microcontroller.Note: The DDC and Hot Plug feature requires BIOS support. Currently it is only possible to use it on boards equipped with the Intel® chipsets (852/855 or newer). Please contact your technical support for information aboutthe required BIOS version for your special Kontron Embedded Modules GmbH board.9 History 9History1.10 03.01.06 BHO Initial Release1.20 09.09.08 PRO Changed to new Kontron StyleUpdated descriptions due to compatibility to all new Intel Chipsets1.21 14.01.09 PRO Replaced DVI-I with DVI-D in functional specification。

3500 64M动态压力监测仪说明书
Specifications and Ordering Information 3500/64 Dynamic Pressure MonitorDescriptionThe 3500/64 Dynamic Pressure Monitor is a single slot, four-channel monitor that accepts input from various high temperature pressure transducers and uses this input to drive alarms. The monitor will have one proportional value per channel, bandpass dynamic pressure. The bandpass corner frequencies will be configured using 3500 Rack Configuration Software, along with an additional notch filter, if needed. A recorder output will be provided for control system applications.The primary purpose of the 3500/64M monitor is to provide:1) Machinery protection by continuously comparingmonitored parameters against configured alarmsetpoints to drive alarms.2) Essential machine information for bothoperations and maintenance personnel.Each channel typically conditions its input signal into various parameters called “proportional values”. Alert and danger setpoints can be configured for each active proportional value. SpecificationsInputsSignal: Accepts from 1 to 4 pressuretransducer signals.3 Wire Transducer InputImpedance:2 Wire Transducer InputImpedance:10KΩ>1.5MΩ with 3.5MΩ typicalSensitivity:Dynamic Pressure: 100 mV/psi (1.45mV/mBar)OutputsFront Panel LED’s:OK LED:TX/RX LED:Bypass LED:Indicates when the 3500/64 isoperating properly.Indicates when the 3500/64 iscommunication with othermodules in the 3500 rack.Indicates when the 3500/64 isin the Bypass Mode.

Individual recordervalues are provided for eachchannel. Monitor operation isunaffected by short circuits onrecorder outputs.Voltage Compliance (current output): 0 to +12 Vdc range across load. Load resistance is 0 to 600 ΩResolution: 0.366uA per bit ±0.25% errorat room temperature, -0.66 to+ 0.70% error overtemperature range. Updatedat 100 mS or less. SignalConditioningDynamic PressureFrequency Response:Direct Filter: “Low Mode” 5Hz. To 4KHz*“High Mode” 10Hz to14.75KHz (Fixed Low Pass)*if no LP filter is chosen, thisextends to approximately5.285KHz.“Low” and “High” filtering modes are options on a channel pair basis. It is possible to select different band pass options on each channel of a channel pair; however, the channels within the pair have to operate in the same filtering mode. Channels 1 and 2 form a pair and channels 3 and 4 form the other pair.In addition, the signal processing can be set up so that ONLY channel 1 input voltage is fed to all four channels. This is “Cascade Mode” (denoted 1->ALL in the 3500 Configuration Software). In “Cascade Mode” the filter mode options are still selected on a channel pair basis. “Cascade Mode” was designed so that one transducer could be used to provide input to four channels for different filtering requirements. This allows four separate bandpass filter options and four separate full-scale ranges to be configured with just one transducer input.The two modes of filtering provide different “qualities” of filtering. LOW MODE:Filter Quality:High Pass (HP): 10-pole (200dB per decade,60 dB per octave)Low Pass (LP):Fixed Low Pass:(LP = none)10-pole (200dB per decade,60 dB per octave)-78 dB minimum attenuationin the stop band.HIGH MODE:Filter Quality:High Pass (HP):Low Pass (LP):6-pole (120 dB per decade,36 dB per octave)-65 dB minimum attenuationin the stop band.Line Refection(Notch)Filter:The line rejection filter hastwo settings, 50 or 60 Hz.Filter response and Centerfrequency selections are validfor both settings.Filter Quality Response:-0.175 dB (98%) of Full Scale; at Center Frequency of +2 Hz And above-0.175 dB (98%) of Full Scale; at Center Frequency of –2 Hz and below-35 dB (1.8%) of Full Scale; from –0.5 Hz of Center Frequency to +0.5 Hz of Center FrequencyAlarmsAlarm Setpoints: Alert and Danger levels areselectable for the directvalues measured by themonitor. All alarm setpointsare set using 3500Configuration software.Alarms are adjustable andcan normally be set from 0 to100% of Full Scale. Theexception is when the fullscale exceeds the range ofthe transducer, in which casethe setpoint will be limited tothe range of the transducer.Alarm Time Delays: Alert:Danger: Alarm time delays can be programmed using 3500 Configuration software.From 1 to 60 seconds, in 1 second intervals.0.1 Seconds minimum and then from 1 to 60 seconds in 0.1 intervals.Proportional ValuesDynamic PressureDirect**This is the primary value for each channel Environmental LimitsTemperature: Humidity: -30º C to 65º C (-22º F to 149ºF) operating.95% non-condensingCE MARK DIRECTIVES: EMC Directives:EN50081-2:Radiated Emissions: Conducted Emissions: EN 55011, Class A EN 55011, Class AEN50082-2:Electrostatic Discharge: Radiated Susceptibility: Conducted Susceptibility: EN 6100-4-2, Criteria B ENV 50140, Criteria A ENV 50141, Criteria AElectrical Fast Transient: Surge Capability: Magnetic Field: EN 61000-4-4, Criteria B EN 61000-4-5, Criteria B EN 61000-4-8, Criteria APower Supply Dip: Radio Telephone: EN 61000-4-11, Criteria B ENV 50204, Criteria BLow Voltage Directives:Safety Requirements: EN 61010-01 Hazardous AreaApprovalsCSA-NRTL/C Class1, Division 2, Groups Athrough DPhysicalMonitor Module (Main Board)Dimensions(Height x Width xDepth):241.3 mm x 24.4 mm 241.8 mm(9.50 in x 0.96 in x 9.52 in).

通用示波器使用说明书
通用示波器使用说明书在家电维修的过程中使用示波器已十分普遍。
通过示波器可以直观地观察被测电路的波形，包括形状、幅度、频率（周期）、相位，还可以对两个波形进行比较，从而迅速、准确地找到故障原因。
正确、熟练地使用示波器，是初学维修人员的一项基本功。
虽然示波器的牌号、型号、品种繁多，但其基本组成和功能却大同小异，本文介绍通用示波器的使用方法。
一、面板介绍1.亮度和聚焦旋钮亮度调节旋钮用于调节光迹的亮度（有些示波器称为"辉度"），使用时应使亮度适当，若过亮，容易损坏示波管。
聚焦调节旋钮用于调节光迹的聚焦（粗细）程度，使用时以图形清晰为佳。
2.信号输入通道常用示波器多为双踪示波器，有两个输入通道，分别为通道1（CH1）和通道2（CH2），可分别接上示波器探头，再将示波器外壳接地，探针插至待测部位进行测量。
3.通道选择键（垂直方式选择）常用示波器有五个通道选择键：（1）CH1：通道1单独显示；（2）CH2：通道2单独显示；（3）ALT：两通道交替显示；（4）CHOP：两通道断续显示，用于扫描速度较慢时双踪显示；（5）ADD：两通道的信号叠加。
维修中以选择通道1或通道2为多。
4.垂直灵敏度调节旋钮调节垂直偏转灵敏度，应根据输入信号的幅度调节旋钮的位置，将该旋钮指示的数值（如0.5V/div，表示垂直方向每格幅度为0.5V）乘以被测信号在屏幕垂直方向所占格数，即得出该被测信号的幅度。
5.垂直移动调节旋钮用于调节被测信号光迹在屏幕垂直方向的位置。
6.水平扫描调节旋钮调节水平速度，应根据输入信号的频率调节旋钮的位置，将该旋钮指示数值（如0.5ms/div，表示水平方向每格时间为0.5ms），乘以被测信号一个周期占有格数，即得出该信号的周期，也可以换算成频率。
7.水平位置调节旋钮用于调节被测信号光迹在屏幕水平方向的位置。
8.触发方式选择示波器通常有四种触发方式：（1）常态（NORM）：无信号时，屏幕上无显示；有信号时，与电平控制配合显示稳定波形；（2）自动（AUTO）：无信号时，屏幕上显示光迹；有信号时与电平控制配合显示稳定的波形；（3）电视场（TV）：用于显示电视场信号；（4）峰值自动（P-PAUTO）：无信号时，屏幕上显示光迹；有信号时，无需调节电平即能获得稳定波形显示。

6、传感器 常用的传感器是霍尔器件和感应线圈。 霍尔器件输出0–5伏或0–12伏的方波 感应线圈输出的是正弦波，其幅度与转速有关。 点火控制信号 从点火控制模块输出的控制信号为0–5 伏 or 0–12 伏方波。
7、次级点火 点火时，线圈次级产生很高的电压，当电压逐步升高到一定值，火花
塞上产生火花，此电压即是点火电压。随后电压迅速下降到另一电压值并 维持一段时间，此电压即是燃烧电压，燃烧时间就是电压维持在燃烧电压 值的时间。在燃烧时间结束时,点火线圈中的能量基本耗尽,残余的能量在 线圈上形成阻尼振荡。

MT3500 发动机分析仪使用说明
使用如上图所示的点火波形检测车辆，已经有好多年的历史了，观察 该图形使你能从细微处分析 车辆的运行状况。理想状态下，该图形非常稳 定，表示每一次点火燃烧过程的电压都一致。各汽缸的图形应该大体相仿。 然而，实际情况并不理想，图形总成会有或大或小的抖动，如点火或击穿 电压忽高忽低，燃烧时间也可能长短不一，这些并不一定表明发动机有故 障。这些可能需要我们有一定时间的经验积累，同时结合其他图形进行综 合分析，但是可以说，理想的图形可能你不能看到
点火控制模块输出的信号不能直接驱动点火线圈，要经过点火放大器 进行放大。
实际上一般都把点火放大器安装在点火线圈内，这种情况下初级点火 信号是测不到的；或者安装在点火控制模块内，这种情况下点火控制模块 输出信号是测不到的。由此可见，通过次级点火信号检测发动机故障和性 能尤为重要。
注意：如果点火系统是电控系统，应先检查是否有与点火有关的故障 码(参看故障码读码器说明书)。

５、点火原理 ５.1 电控点火系统
MT3500 发动机分析仪使用说明
电控点火系统用一组传感器来收集与发动机相关的信息，如转速、冷 却温度和发动机负荷等。位置传感器和转速传感器是点火系统需要的最重 要的信息，这些信息来自叶轮传感器或凸轮轴传感器。
点火控制模块根据收集到的信息计算点火时间和充电时间，如果某个 传感器工作不正常，将导致输出信号不正确，因此现代的控制模块要检查 传感器送来的信号是否真实可信，若有不可信的信号时有可能不输出任何 信号。
为了查看单个汽缸的次级点火波形。进入“次级点火分析”后，出现 如下图所示画面，
汽缸选 F1 键/左右键来选择电压量程和汽缸选择，例如：一般 汽车二次点火电压为 5-8Kv，此时将光标移至图示位置，按下 YES 键弹出量 程菜单，通过上下键来选择所需量程，电压量程有以下几种选择：：1kV/格， 2kV/格，4kV/格，6kV/格，10kV/格。

第二章 仪器使用说明
第一节 次级点火分析 第一部分 点火测试入门
１、点火系统种类 有分电盘的传统点火系统在汽车上的使用已有很久的历史，现在已逐
步被直接点火系统(DIS)所取代。 直接点火系统分为三种类型： 1)使用双端输出点火线圈的双点火系统(DEC)。 2)使用单端输出点火线圈的单点火系统(CPC)。 3)使用集成火花塞的集成点火系统(COP)。 这三种点火系统的共同特点是点火线圈的输出不经过分电盘而直接送
这种点火系统的优点是维修检测相对容易，缺点之一是机械部件及电
- 10-
MT3500 发动机分析仪使用说明
触点容易磨损，寿命短。另外高压连接部分也容易损坏。 ３、双点火系统 (DEC)
双点火系统完全由电子器件组成，没有机械部件。每两个缸共用一个 点火线圈，线圈次级的两个电极分别接一个火花塞. 也就是说总是有两个 火花塞同时点火，其中一个缸处于正常点火，另一个缸则处于排气过程中 (点火火花“浪费”在排气中)，处于排气的这个缸内压力接近空气压力， 只需很低的点火电压, 浪费很少的电能。

安全操作规范
尽量在通风良好的环境下使用仪器，如果在室内通风不良的环境下使 用应尽量使车辆的尾气排放到室外。 严禁明火接近燃油系统，包括：吸烟、电器打火等 保持仪器及测试联线与汽车的运动部件有一定距离，例如：传动皮带、 风扇，齿轮等 蓄电池内的电解液具有腐蚀性。防止电解液接触皮肤及工具，如果不 慎接触到已受腐蚀的蓄电池电极应及时用水冲洗。 禁止用导电物体短路电池的正负电极 在发动机运转的情况下进行测试时应将档位置于“空档”，并将制动 杆置于“泊车”位置。 防止仪器被冷却液、水、油或其它液体弄湿 禁止将该仪器用于非汽修的测量 安装仪器的扩展模块或部件时应先关闭仪器电源 进行各种测试前应首先连接好搭铁 在拆卸防滑护套更换电池时，应先断开仪器的所有测试接线并关闭仪 器电源。 禁止在没有安装防滑护套的情况下使用仪器 禁止使用绝缘外皮破损的测试线及测试探头
压、频率、脉宽、占空比等； ★ 上部有 6 个测试通道，可同时测 6 缸次级点火波形； ★ 时基显示可以精确到 125uS/格； ★ 数字万用表功能； ★ 元件测试功能； ★ 仪器存储容量可达到 32Mb； ★ 应用三节电池供电，低功耗设计、自动关机功能更能延长使用时间； ★ 数据文件管理功能； ★ 系统设置功能； ★ 软件直接安装功能；
双点火系统的优点之一是故障少，几乎不需要维护。另一个优点是点 火系统的可调性好，表现在其发出的电波幅射少，耗油低。缺点是仍需要 高压线及火花塞连接器。这些地方仍容易出问题。 ４、单点火系统(CPC)和集成点火系统(COP)
每缸有一独立的点火线圈，是当今最为先进的点火系统。这种点火系 统分为两种类型：单点火(CPC)、集成点火(COP)；集成点火系统将点火线 圈集成在火花塞上，单点火则用一根高压线从点火线圈接到火花塞。

MT3500 手持发动机分析仪应由专业的汽车维修人员来操作，此操作人 员应受过适当的培训且对于汽车的机械、电器、电路各方面均有详细的了 解。在使用过程中，操作者本身应知道如何避免可能对使用者本身，其他 伴随人员，受检测车辆及相关仪器造成的伤害或危险。因此，使用前请务 必详读下列的安全操作规范：
到火花塞。
２、传统点火系统
传统点火系统主要由蓄电池、凸轮、断路器、点火线圈、分电器、火 花塞组成。蓄电池的作用是供给点火系统所需电能，凸轮和断路器接通或 断开点火系统电源。点火线圈储存点火能量并将蓄电池电压转变为点火高 压。断路器的作用是接通或切断点线圈初级电路；分电器的作用是将点火 线圈产生的点火高压按照发动机的工作顺序输送至各缸火花塞。火花塞将 点火高压引入气缸燃烧室，并在电极间产生电火花，点燃可燃混合气。

MT3500 发动机分析仪使用说明
禁止在仪器信号输入端输入超过 500 伏的直流或交流电压。 检测次级点火时严禁使用非指定的及已损坏的测试线及探头 防止人体接触次级点火会产生高压的部分，注意安全 测试次级点火前应先将测试线与仪器连接，再与发动机连接。 禁止在未将仪器的搭铁端与汽车的搭铁可靠连接的情况下使用仪器。 严禁将测试夹或测试探头与次级点火电路的导电部分直接接触。 串行联机接口是用于联接电脑、扩展模块的通信接口，严禁使用非指 定的连接线及其它未指定的任何设备接入 使用完毕后，应将所有的接头，测试导线及测试夹卸下，并完整保存 于 MT3500 的包装箱中。
点火或击穿电压：若点火电压过高，甚至超过屏幕范围，表明在次级 点火电路中电阻值过高。线路中有开路，火花塞损坏，高压线或火花塞间 隙过大等都有可能造成击穿电压过高的现象，相反，如果击穿电压过低， 表明在点火次级电路中电阻值低于正常值，可能是火花塞太脏或破裂，高 压线漏电等原因造成。
燃烧线及燃烧时间：燃烧线上如有过多的杂波，表示汽缸点火不良。 或是由于点火过早，喷油器损坏，火花塞脏污等原因造成。燃烧线持续时 间的长度与汽缸内混合气体浓度有关。通常情况下，燃烧时间超过2ms就表 示混合气体过浓。相反如果燃烧时间少于0.75ms表示混合气过稀。
若跳火电压或点火燃烧电压偏高，其可能原因如下： ★ 二次点火系统阻抗过高(分缸线，分电盘盖，分火头，或火花塞) ★ 混合比过稀 ★ 压缩压力过高 若跳火电压或燃烧电压偏低，可能原因如下： ★ 火花塞间隙太小，或火花塞上油 ★ 二次点火系统漏电(打铁不良) ★ 混合比过浓 ★ 压缩压力过低 二次点火波形中跳火电压线长度应在 1 到 3ms 之间，且每缸皆同，而 且此跳火电压线必须呈一直线，不可偏移、倾斜。若产生此现象，则可能 为混合比不正确或是发动机中汽缸空气及燃油混合比异常紊乱。
四．检测项目树形图
