To comply with the WEEE Directive,Kramer Electronics has made arrangements with the European AdvancedRecycling Network (EARN) and will cover any costs of treatment, recycling andrecovery of waste Kramer Electronics branded equipment on arrival at the EARNfacility. For details of Kramer’s recycling arrangeme nts in your particular countrygo to our recycling pages at /support/recycling.3 OverviewThe Kramer VP-427A is a receiver/scaler for HDBaseT twisted pair, HDMI,bidirectional RS-232 and IR signals. The unit receives an HDBaseT signal that itconverts to HDMI, IR and passed RS-232 signals. It up- or down-scales the pictureto match the resolution of the HDMI monitor.The VP-427A also features:∙An HDBaseT input∙An HDMI output∙ A bidirectional RS-232 port for embedding/de-embedding control commands in the HDBaseT data stream∙Infrared input and output ports for controlling devices over the HDBaseT data stream∙Embedded audio supporting LPCM 2CH∙Maintains constant sync on the output, even when the input video signal is lost or interrupted∙ A simultaneous analog audio output of the embedded HDMI audio∙System range of up to 70m (230ft).∙ A built-in ProcAmp for convenient signal adjustment∙An On-Screen Display (OSD) for easy setup and adjustment, accessible via the front-panel buttons∙ A non-volatile memory that retains the last settings used∙ A freeze button∙ A USB connector for firmware upgradingThe machine is fed from an external 5V DC source, making it suitable for fieldoperation.3.1 Defining the VP-427A HDBaseT to HDMI+AudioReceiver/ScalerThis section defines the VP-427A.Figure 1: VP-427A HDBaseT to HDMI+Audio Receiver/Scaler4 Connecting the VP-427AAlways switch off the power to each device before connecting it to yourVP-427A. After connecting your VP-427A, connect its power and thenswitch on the power to each device.To connect the VP-427A as illustrated in the example in Figure 2:1. Connect the output from an HDBaseT transmitter (for example, a TP-582T)to the HDBT IN RJ-45 connector.2. Connect the AUDIO OUT3.5mm mini jack connector to an unbalancedstereo audio acceptor (for example, an amplifier).3. Connect the HDMI OUT connector to an HDMI acceptor (for example, adisplay).4. Connect an IR receiver to the IR IN 3.5mm mini jack.5. Connect the IR OUT 3.5mm mini jack to an IR emitter.6. Connect the RS-232 9-pin D-sub connector to an RS-232 port (for example,a display).7. Connect the 5V DC power adapter to the power socket and connect theadapter to the mains electricity (not shown in Figure 2).Figure 2: Connecting the VP-427A HDBaseT to HDMI+Audio Receiver/Scaler4.1 RS-232 Control over HDBaseTYou can connect to the transmitter/receiver system via an RS-232 connectionusing, for example, a PC. Note that a null-modem adapter/connection is notrequired.To connect a PC via RS-232, connect the RS-232 9-pin D-sub rear panel port onthe transmitter/receiver system unit via a 9-wire straight cable (only pin 2 to pin 2,pin 3 to pin 3, and pin 5 to pin 5 need to be connected) to the RS-232 9-pin D-subport on your PC.Figure 2 shows RS-232 bidirectional control of the DVD that is connected to aTP-582T.4.2 IR Control Over HDBaseTSince the IR signal on the TP-582T transmitter and VP-427A receiver isbidirectional, you can use a remote control transmitter (that is used for controllinga peripheral device, for example, a DVD player) to send commands (to the AVequipment) from either end of the transmitter /receiver system. To do so, you haveto use the Kramer external IR sensor on one end (P/N: 95-0104050) and theKramer IR emitter cable on the other end (P/N: C-A35/IRE-10)Two IR Emitter Extension Cables are also available: a 15 meter cable and a 20 meter cable.The example in Figure 2 illustrates how to control the DVD player that isconnected to TP-582T using a remote control, via the VP-427A. In this example,the External IR Sensor is connected to the IR connector of the VP-427A and an IREmitter is connected between the TP-582T and the DVD player. The DVD remotecontrol sends a command while pointing towards the External IR Sensor. The IRsignal passes through the TP cable and the IR Emitter to the DVD player, whichresponds to the command sent.5 Operating the VP-427AThe VP-427A is operated directly using the front panel buttons and the OSD menu(see Section 5.2).5.1 Operating the VP-427A from the Front Panel ButtonsDuring normal operation (without the OSD), the front panel buttons perform thefollowing functions:∙Pressing MENU opens the on-screen display (OSD) main menu (seeSection 5.2), the next press closes the OSD∙Pressing +/FREEZE freezes the display, the next press unfreezes the display∙Pressing MENU and –/AUTO ADJUST together resets the display to 720p∙Pressing ENTER and +/FREEZE together resets the display to XGA5.2 Using the OSDYou can use the OSD to set a wide variety of parameters. When the MENU buttonis pressed, the main menu opens (see Section 5.2.2) allowing access to all thedevice settings.5.2.1 Operating the OSD from the Front Panel ButtonsWhile the OSD is open, the front panel buttons perform the following functions:∙Pressing - and + move forward and backward through the menu items and decrement or increment the parameter values∙Pressing ENTER selects and activates a menu item or accepts theparameter value set∙Pressing MENU closes the OSD menuThe menu times out by default after 10 seconds. To change the OSD display time,adjust the OSD/TIMER parameter.As an example of setting parameters, to increase the contrast on the display:1. From normal operation, press MENU.The OSD main menu appears on the screen.2. Press the + or – button to highlight CONTRAST.CONTRAST changes to green when highlighted.3. Press ENTER.The contrast value parameter changes to red.4. Press the + button to increase the value (increase the contrast) orthe – button to decrease the value (decrease the contrast).The value ranges from 0 to 100.5. Press ENTER to set the value.The contrast value parameter changes back to white.6. To return to normal operation, highlight EXIT and press ENTER, pressMENU, or wait until the menu times out.5.2.26 Technical Specifications6.1 Input Resolutions SupportFor the latest information on our products and a list of Kramer distributors, visit our Web site where updates to this user manual may be found.

图12-2 通用串行通信接口主机和从机
图12-2说明了USCI在3线和4线模式下作为主机时的配置。当数据被送到传输数据缓冲器 UCxTXBUF时，USCI开始数据传送。当TX移位寄存器空了后，UCxTXBUF缓冲区的数据被传送到其 中， 在UCxSIMO上传送数据， 起始位是最高位还是最低位， 决定于UCMSB标志位的设置。 而UCxSOMI 上的数据在反向跳边沿下移入接收移位寄存器。当字符接收到之后，接收数据从RX移位寄存器 送入接收数据缓冲器UCxRXBUF，并且置位接收中断标志UCxRXIFG，表示接收/发送操作完成。 发送中断标志位UCxTXIFG被置位后，表明数据已从UCxTXBUF缓冲区进入TX移位寄存器， UCxTXBUF寄存器已经为发送新数据做好准备，但并不意味着传送和接收的完成。 为了在主机模式下接收USCI数据，数据必须事先写入UCxTXBUF，因为接收和发送操作不是 马上进行的。 4线SPI主机模式 在4线主机模式中，UCxSTE用来防止与其它主机相冲突并象表12-1描述的那样控制主机。当 UCxSTE处于主机不活动状态时： UCxSIMO 和 UCxCLK设置为输入，不再驱动总线。 出错位UCFE置位，表明在通讯的完整性上，使用者未按照规则操作。 内部状态被复位时，移位操作取消。 如果数据写入UCxTXBUF而主机通过UCxSTE位保持非工作状态， UCxSTE转换为主机工作状态， 数据立即被发送。如果一个正在工作的发送过程，因UCxSTE转换为主机不运行状态而取消时， 当UCxSTE转向主机运行状态时数据需要被重新写入UCxTXBUF。 UCxSTE输入信号不能应用3线主机 模式。 12.3.4 从机模式

简要说明 处理单元
处理单元是基于兼容正交CPU指令集的。这种设计结构 对应用开发高度透明且易于编程。因此所有的操作，除了程 序流程指令，都是通过源操作数的7种寻址模式和目标操作数 的四种寻址模式的组合对寄存器操作进行的。
