RAM System 2000用户手册说明书

INSTALLING THE RAM SYSTEM 2000 Thanks for purchasing the RAM System 2000. Please make sure the following items are in the box when you open it.•This manual.•RAM System 2000 main unit.•Power Supply labelled HA-PSU03.•Bluetooth antenna.•IEC Cable.Depending on your system requirements, you will need several TRS cables to hook up your system. Please check your input sources and output destinations and buy the correct cables.Additionally, please insert the Bluetooth antenna in its threaded connector in case it comes unplugged from the factory.The power supply is of the auto switching type so it works worldwide without adjusting anything. In case your country uses a different mains cable other than the one provided in the box, just get the correct one and you are done. Plugging the unit will display a welcome message and firmware unit´s version. Please note that after turning on the unit, MUTE will always be engaged regardless of the level shown on the red knob. This is to prevent damage of your speakers due to excessive level on startup.Any time you plug the unit on, the status of the RAM System will be that of the last time it was turned off, so there is no need to reset preset levels or talkback gain. Last input and output chosen is also stored.GENERAL DESCRIPTIONThe Heritage Audio RAM SYSTEM 2000 is a professional monitor controller in a convenient tabletop format. With its matrix of inputs and outputs, coveringbalanced and unbalanced analog, Spdif digital and the innovative professional quality HA Bluetooth technology, the System 2000 will cover all the monitoring needs of the most demanding professional facilities at a price never heard before.The level control is taken care of by means of microprocessor controlled gold plated relays, giving an exceptional resolution of 64dB of attenuation in 1dB steps. Keeping active electronics to a minimum, the attenuator is buffered using state of the art Burr Brown circuitry for negligible coloration and no noise.Headphone monitoring is as critical as main speaker is. Usually a weak part even in the most expensive units, the RAM System 2000 employs very high current drivers in a diamond buffer configuration which are able to drive any headphones to very high levels without coloration or noise. It has 2 amplifiers individually configurable.INPUT FEATURESThe RAM System 2000 has the following stereo inputs:•INPUT 1: Balanced, accessible on a pair of TRS Jack connectors.•INPUT 2: Exactly as Input 1.•INPUT 3: Balanced by default, it can be configured as unbalanced -10dBV by pressing SHIFT + IN3. The same key combination wouldreturn this input to its balanced +4 configuration.•DIGITAL: Transformer isolated, it is available on the RCA connector on the back of the unit. It is able to read signals up to 24 bit/ 96Khzand gets the word clock from the input source.•BLUETOOTH: This input features the same architecture found in the acclaimed Heritage Audio BT-500. If you are not familiar with it, theBT-500 is an Audio Streaming device in a convenient 500 Seriesformat. It streams audio from your Bluetooth-equipped device anddelivers a fully balanced, +22dBu stereo output. Integration of mobiledevices intro a professional studio environment has never beeneasier. More info on the Bluetooth features later.MONITORING OUTPUT FEATURESThe RAM System 2000 features 3 pairs of balanced outputs labelled OUT1, OUT2 and OUT3, available via TRS jacks on the back of the unit.An additional SUBWOOFER output is available on a balanced TRS as well. It follows the input selected, and outputs a mono, unfiltered combination of both channels.ADDITIONAL OUTPUTSIn addition to the monitoring outputs, the RAM System 2000 features the following outputs:•MIX OUTPUT: It follows the input signal and is taken PRE FADER, meaning its level is unaffected by the monitoring attenuation. It istherefore ideal for recording the mix at the same time, or as anadditional cue send.•CUE OUTPUT: Working in tandem with the CUE INPUT, it works as a traditional CUE send, where the CUE Output follows the CUE inputplus the Talkback signal when this is in use.SIGNAL MONITORING FACILITIESAs previously explained, the heart of the RAM System 2000 is its microprocessor controlled, ladder type attenuator. This can be accessed in 2 ways:•Using the Red Level Knob: As in any traditional monitoring system.Fully clockwise it performs at unity gain (maximum level) whilstreducing it in 1dB steps up to 64. After this the unit turns Mute on.•Using the LEVEL PRESET OPTIONS: The RAM System 2000 has the ability to store 2 different level presets, which override the Red Levelknob position. Pressing SHIFT + OUT3 (Level Preset) will ask for whichof the 2 presets wants to be stored (1 or 2). Confirmation is given bypressing the corresponding key, OUT1 (Level Preset 1) or OUT2(Level Preset2).Pressing SHIFT + OUT1 (Level Preset1) will make themonitoring level that of the stored preset, same for preset 2.ADDITIONAL MONITORING FEATURESThe RAM System has the usual MUTE, DIM and MONO functions often found in this type of units with expanded flexibility as follows:•MUTE: Global Mute, equivalent to rotary knob all fully counter clockwise.•MUTE L, MUTE SUB and MUTE R: Individual Mute functions per speaker. Pressing SHIFT + any individual MUTE will function as aSOLO for that given speaker.•DIM: Attenuates further 20 dB from the attenuation marked by either the red knob or the level preset.•MONO: Accessible as SHIFT + MUTE, it outputs a mono signal to the selected output.TALKBACK FACILITIESThe RAM System 2000 features talkback facilities in a similar fashion to the large format consoles. Talkback signal can be assigned to the Mix signal (following Input selected), by pressing TB MIX. It can also be assigned to the dedicated CUE input by pressing TB CUE, or at both at the same time,pressing TB ALL. All 3 buttons are momentary (they do not engage), so need to be pressed for the talkback to function. This avoids sending embarrassing comments to the talent by mistake.The talkback signal is taken from the Electret microphone found in the front panel and further amplified. Controls for talkback mic gain are SHIFT + TBMIX for lowering the gain and SHIFT + TBCUE for raising it.Pressing any of the talkback keys will activate the DIM function in order to avoid feedback from the mic to the speakers.HEADPHONE MONITORINGYour RAM System 2000 provides with 2 different headphone amplifiers, placed at the left and right front panel ends. They are capable of extremely loud levels without distortion, noise or coloration of any kind so, before plugging your headphones in, make sure the headphone level is at its minimum setting, and adjust accordingly.Each headphone amplifier can have 2 different sources. MIX (following the selected input source), or CUE(following the CUE input on the back panel connectors).This allows for different monitoring mixes for the talent and the recording engineer.Selecting is possible by means of the red button located close to each of the headphone jacks. (Button pressed: CUE, button depressed: MIX).UNDERSTANDING THE BLUETOOTH INPUT There is still a popular misconception that Bluetooth is detrimental to the audio quality. Although this has been true in the past, it is no longer the case. Bluetooth is just a “wireless serial port” and, as so, has no ability to interactwith your sound quality. However, in order to fit the heavy data traffic that digital audio needs, digital audio compression is applied. This is the real source for audio degradation in Bluetooth connections.This being said, modern Bluetooth technology allows for very high quality codecs taking care of the audio data and, which is more important, pre coded data (such as that in iTunes) is kept unmolested.NO MORE MINI JACKSEmploying last generation audio specific Bluetooth technology, the best Codecs your devices can support and a state of the Art, Burr Brown based analog signal path, it solves the already classic, irritating problem of connecting your iOS or Android device to your Studio setup.To this day this has been solved using mini jack to XLRs adaptor cables, but the limitations of mobile devices’ analog audio paths have become clearly apparent.Listening to references on the iTunes Store, recordings sent by email, Spotify, You Tube, you name it. You do it every day, all the time. Nevertheless integration has been non convenient to say the least, until now.SOUND QUALITY OVER BLUETOOTHThe RAM System 2000 Bluetooth device automatically recognizes your device´s best Codec option and uses it for streaming.Apple´s iTunes Store and You Tube use AAC* as native so streaming from an iPhone or iPad will result in a lossless transmission, much better than an analog wired connection!!Vast majority of Android devices have already adopted the amazing sounding “Qualcomm® aptX™ audio” Codec **, which is nearly lossless and the standard that wireless high quality headsets and sound bars are adopting. For a complete list of devices currently supporting aptX please visit:/products/browse/categoriesIn case your device can´t support neither AAC nor aptX, the BT-500 will stream audio using the classic SBC codec.(*) Heritage Audio is an official AAC licensee.(**) Heritage Audio is an official aptX licensee.BURR BROWN´S PEDIGREE IN THE ANALOG PATHThe RAM System 2000 Bluetooth device substitutes your mobile device´s analog circuitry with a state of the art, fully differential Burr Brown balanced output stage which delivers a full 0dBfs = +22dBu output able to drive a load of 600 ohms. This allows direct level comparisons while mastering or mixing with Apple´s iTunes Store or mobile stored reference mixes.SYNCHRONIZING YOUR DEVICE WITH THE RAM SYSTEM 2000Synchronizing your mobile device with the RAM System 2000 is as simple as pairing any other Bluetooth device. It will appear as “HERITAGE RAM 2000” on your Bluetooth devices´ list.You Tube hosts nice tutorials about how to do so in both Android and iOS if you need help.The System 2000 automatically selects the best Codec supported by your mobile device, so no configuration is needed.OPERATIONWhenever a device is paired with the RAM System 2000, the “SYNC” LED will light. From then on, your mobile device takes over the transmission, including Transport control (PLAY, STOP, etc.) and Level (Volume).Active streaming is confirmed by corresponding Codec LED being turned on. Please note Codec IS NOT configurable. It is automatically chosen from the best available option on your mobile device.Devices can only be paired one at a time. Whenever a different device needs to be paired, Bluetooth needs to be reset, so SHIFT + BT buttons must be pressed down.SUMMARY OF SOFT FUNCTIONSWhile main functions in the RAM System 2000 are simply accessible by pressing the corresponding key, several others are accessible as a combination, employing the SHIFT key for this purpose. These have been described all along this manual, however for easy recall, they are listed below:•SHIFT + IN 3: Turns IN 3 from balanced +4 dBu nominal to unbalanced -10 dBV nominal. Pressing again does the opposite.•SHIFT + BT: Resets the Bluetooth connection.•SHIFT + MUTE L: Solos the speaker L.•SHIFT + MUTE SUB: Solos the SUB.•SHIFT + MUTE R: Solos the speaker R.•SHIFT + OUT 1: Sets the Level Preset 1.•SHIFT + OUT 2: Sets the Level Preset 2.•SHIFT + OUT 3: Saves level preset (confirmation of preset 1 or 2 needs to follow).•SHIFT + MUTE: Activates MONO listening.•SHIFT + TB MIX: Lowers the talkback mic gain.•SHIFT + TB CUE: Raises the talkback mic gain.TECHNICAL SPECIFICATIONS •Maximum analog input level: Over +27.5 dBu•Digital input: Up to 24 bit/96 Khz. 0dBfs = +22 dBu at the output, all fader up.•Bluetooth input: AAC, aptX or SBC, 0dBfs=+22dBu at the output, all fader up.•DIM attenuation: -20db.•Maximum output level: Over +27 dBu into 600 ohms.•Noise: Better than -99 dBu.•THD: Better than .001% at 1Khz, balanced input to balanced output, all fader up.DISCLAIMER-Qualcomm is a trademark of Qualcomm Incorporated, registered in the United States and other countries, used with permission.-aptX is a trademark of Qualcomm Technologies International, Ltd., registered in the United States and other countries, used withpermission.-AAC and Bluetooth® trademarks are the property of their respective owners.-Heritage Audio is a non-exclusive licensee of Qualcomm® aptX™ audio.-Heritage Audio is a non-exclusive licensee of AAC.LIMITED 2 YEAR WARRANTYHeritage Audio RAM SYSTEM 2000 is warranted by Heritage Audio SL to be free from defects in materials and workmanship for the period of 2 years to the original purchaser.

1.4 串口通讯接口及协议说明 1.4.1 LN-GPS模块通讯接口概述 LN-GPS模块对各种授时接收系统提供三种通讯接口,包括CAN接口两个,RS-485串行接口四个,RS-232串行通讯接口两个。串行口通讯的物理层协议为RS-485与RS-232,可与任何具有RS-485或RS-232接口的计算机、设备或系统,特别是DCS系统实现通讯,通常推荐RS-485方式进行距离较远或者环境较恶劣情况下的通讯。
1.4.2 LN-GPS模块串行口通讯接口方式 通讯接口:RS-485或RS-232 校验方式:8位CRC校验 数据格式:9600,n,8,1 通讯方式:主从通讯,LN-GPS模块定时向外广播时间,接收系统查询接收LN-GPS模块的数据。 接收数据格式(其中CRC校验码是前面八个字节的校验校验码): 1 2 3 4 5 6 7 8 9 10 11 12 数据起始字节 年 高 字节 年 低 字节 月 日 时 分 秒 毫秒高 字节 毫秒低 字节 CRC校验码 数据停止字节 0x24 0x07 0xD5 0x04 0x18 0x0A 0x2D 0x18 0x01 0x98 0x97 0x40
数据含义:2005年4月24日10时45分24秒408毫秒 表1.4-1 接收数据格式
1.5 注意事项 1. 确保天线放置在室外,尽量避免障碍物的遮挡。 2. 尽量要避开高大建筑物、茂密植物的遮挡。 3. 天线不要侧放,固定旋杆旋入整流罩柄后应基本垂直于水平面。 4. 不要擅自延长天线的电缆。 5. 不要用金属罩、网,罩住天线。 6. 不要和其他无线电发射天线在短距离内混合安装。如:雷达天线、车载电台天线等等。通常情况下距离雷达的发射天线距离应在4~5 米以上;距离大功率单边带的发射天线应2~3 以上;距离普通车载电台发射天线应在40~60 厘米以上。 7. 不要浸泡在液体环境中使用。授时天线无防雨密封设计,液体高度不可高于整流罩柄末端。 8. 严禁将GPS 专用天线作为其他设备的发射天线!这样不但会烧毁天线,而且会烧毁GPS 接收板,甚至用户端接收电路。

图2.1.1-1 OPC通讯示意图 2.1.2 OPC的优越性 硬件供应商只需提供一套符合OPC Server规范的程序组,无需考虑工程人员需求。软件开发商无需重写大量的设备驱动程序。 工程人员在设备选型上有了更多的选择。OPC扩展了设备的概念。只要符合OPC服务器的规范,OPC客户都可与之进行数据交互,而无需了解设备究竟是PLC还是仪表,甚至在数据库系统上建立了OPC规范,OPC客户也可与之方便地实现数据交互。 2.1.3 OPC的适用范围 OPC设计者们最终目标是在工业领域建立一套数据传输规范,并为之制定了一系列的发展计划。现有的OPC规范涉及如下领域: 在线数据监测:实现了应用程序和工业控制设备之间高效、灵活的数据读写。 报警和事件处理:提供了OPC服务器发生异常时,以及OPC服务器设定事件到来时向OPC客户发送通知的一种机制。 历史数据访问:实现了读取、操作、编辑历史数据库的方法。 远程数据访问:借助Microsoft的DCOM技术,OPC实现了高性能的远程数据访问能力。 OPC近期将实现的功能还包括安全性、批处理、历史报警事件数据访问等。
