InstallationConnect the Switch to Your Network During initial setup, you must connect the switch to a network that you can access with a local WiFi connection to use the Insight mobile app, or to the Internet to use the Insight Cloud Portal.For Gigabit connections, use Category 5e (Cat 5e) or higher-rated Ethernet cables terminated with RJ-45 connectors.To use an SFP port, you must insert a 1G SFP transceiver module, which is available from NETGEAR.To use an SFP+ port, you must insert either a 10G SFP+ or 1G SFP transceiver module, which is available from NETGEAR. ¾To connect the switch:1. Connect devices to the network ports on the switch.2. Connect the switch to a network.3. Power on the switch and wait for two or three minutes.The Power LED lights green, indicating that switch completed its startup process and is available on the network.The switch receives an IP address from a DHCP server (or a router that functions as a DHCP server) in your network. If your network does not include a DHCP server, the switch uses 192.168.0.239 as its default IP address.4. To check the port connections from the switch to the powered-ondevices that you connected, do the following:• Make sure that the Ethernet cables are plugged in correctly.• Check the left LED for each port on the switch.The left port LED lights solid green to indicate a valid connection to a powered-on device and blinks green to indicate traffic on this port.Package ContentsUnpack the box and verify the contents:• Switch model GC752X or GC752XP • Power cord (localized to the country of sale)• Rack-mount kit• Four rubber footpads for tabletop installation • Installation guideInsightGC7252XPAccess the Switch for ConfigurationThe NETGEAR Insight app lets you use your mobile device to discover,configure, manage, and monitor your switch.

The switch provides a total powerbudget of 505 watts. If the PoE Max LED is solid amber, disconnect one or more powered devices (PDs) to prevent PoE oversubscription. Start by disconnecting the PD from the highest-numbered port.Note: You can manually override the amount of power that is reserved for each PoE port and attached PD by using the Insight mobile app or the Insight Cloud Portal.• Check the right LED for the port on the switch that is connected to apowered PD. The right port LED on the switch lights solid green to indicate that PoE is being delivered to the PD. If the right port LED lights solid amber, a PoE fault occurred.SupportThank you for purchasing this NETGEAR product.

MASCHINE!MASCHINE is a groove production studio that implements the familiar working style of classi-cal groove boxes along with the advantages of a computer based system. MASCHINE is ideal for making music live, as well as in the studio. It’s the hands-on aspect of a dedicated instru-ment, the MASCHINE hardware controller, united with the advanced editing features of the MASCHINE software.Creating beats is often not very intuitive with a computer, but using the MASCHINE hardware controller to do it makes it easy and fun. You can tap in freely with the pads or use Note Re-peat to jam along. Alternatively, build your beats using the step sequencer just as in classic drum machines.Patterns can be intuitively combined and rearranged on the fly to form larger ideas. You can try out several different versions of a song without ever having to stop the music.Since you can integrate it into any sequencer that supports VST, AU, or AAX plug-ins, you can reap the benefits in almost any software setup, or use it as a stand-alone application. You can sample your own material, slice loops and rearrange them easily.However, MASCHINE is a lot more than an ordinary groovebox or sampler: it comes with an inspiring 7-gigabyte library, and a sophisticated, yet easy to use tag-based Browser to give you instant access to the sounds you are looking for.What’s more, MASCHINE provides lots of options for manipulating your sounds via internal ef-fects and other sound-shaping possibilities. You can also control external MIDI hardware and 3rd-party software with the MASCHINE hardware controller, while customizing the functions of the pads, knobs and buttons according to your needs utilizing the included Controller Editor application. We hope you enjoy this fantastic instrument as much as we do.

EFM32 微控制器应用指南说明书
...the world's most energy friendly microcontrollers USART/UART - AsynchronousmodeAN0045 - Application NoteThis application note describes how to configure the EFM32 UART or USART tooperate in asynchronous mode.An included software example for the EFM32GG-DK3750 Giant Gecko DevelopmentKit shows how to implement interrupt driven receive and transmit, utilizing the on-board RS-232 transceiver.This application note includes:•This PDF document•Source files (zip)•Example C-code•Multiple IDE projects1 Universal Asynchronous Receive Transmit (UART)1.1 Basic TheoryA UART is a well established standard for low cost, low speed serial communications over a simple 2-wire (plus ground) interface.Asynchronous communications differs from synchronous communications in that synchronization between transmitter and receiver are encoded into the transmitted signal, rather than using a separate wire to transfer the transmitter clock to the receiver.Embedding the synchronization information in the data reduces the cost of cables and connectors, and may also be beneficial on a space constrained PCB or if one wants to keep the pin-usage low. On the other side adding synchronization information to the datastream increases overhead, causing the effective data rate to be lower than the baud rate.Normally, asynchronous communication modes facilitate somewhat lower data rates compared with synchronous modes. Some of the reason is the above mentioned overhead, but also because asynchronous communications may impose stronger requirements on the transceivers and the transmission lines between receiver and transmitter.Low cost and low power transceivers usually don't have advanced clock recovery mechanisms, but simply rely on the combination of oversampling and that the receiver and transmitter clock frequencies are sufficiently close.1.2 RS-232UART does not specify any electrical characteristics such as signal levels etc. Instead, several separate electrical interface standards can be applied. Most common is RS-232, but other well known standards include RS-422, RS-485, and also some standards that don't use electrical signalling such as IrDA.In this application note, the included software example uses the RS-232 transceiver that is included on the Development Kit.1.3 Using the EFM32 UART/USARTThe information necessary to configure and use the UART/USART modules on an EFM32 microcontroller are contained in the device family reference manual. This application note also presents some further details and clarifications.1.3.1 Clock SourceOften, the HFRCO is too unprecise to be used for communications. So using the HFXO with an external crystal is recommended when using the EFM32 UART/USART.In some cases, the internal HFRCO can be used. But then careful considerations should be taken to ensure that the clock performance is acceptable for the communication link.1.3.2 Baud Rate CalculationThe baud rate is given by the following expression:Baud rate(1.1)Where•br is baud rate,•f HFPERCLK is the frequency of the HFPERCLK branch of the high frequency clock tree (See figure on CMU Overview in device family specific reference manual),•OVS is the oversampling factor, and•DIV is the configurable part of the fractional divider in the UART/USART module.When rearranged, one can compute a clock divider setting that will obtain a wanted baud rate by the following formula:Clock divisor(1.2) The clock divider is a fractional divider dividing by (1+DIV/4) where DIV is a 15 bit value ranging from 0 to 32767. I.e. the clock can be divided by a factor from 1 to 8192.75. Depending on the configurable oversampling factor the baud rate is given by a further division by a factor of 4, 6, 8 or 16. This results in a baud rate that is the clock frequency divided by 4 to 131,084. If the HFXO is run at 32 MHz, baudrates between 8 Mbps and 244.11 bps can be generated as long as the HFPERCLK prescaler is set to 1.It is worth noting that the equations in this application note differs somewhat from the reference manual. The reason is that the reference manual refers to CLKDIV which is the entire 32-bit register value, of which only the 15-bit wide bitfield DIV is actually used to control the fractional divider. In this document, the bitfield DIV is consistently used.2 Software ExampleThe included software example is made for the EFM32 Giant Gecko Development Kit, EFM32GG-DK3750. However, with minor modifications the project will also work on our other EFM32 development kits. It can also be ported to the starter kits. But because the starter kits don't include RS-232 line drivers, please ensure that signal levels are compatible before establishing a communication link between two parties. Connecting the EFM32 UART directly to a PC serial port will damage the EFM32.The kit's on-board RS-232 transceiver is used to demonstrate a possible interrupt based asynchronous mode configuration of an EFM32 U(S)ART peripheral.The example uses interrupt driven transmit and receive. When transmitting a block of data, the data is first copied into a transmit queue. The U(S)ART TXBL interrupt is enabled. When the UART is ready to transmit, the TXBL interrupt goes high. The interrupt handler function fetches one byte from the transmit queue and copies it to the UART transmit buffer (UARTn->TXDATA). While transmitting, the CPU is free to perform other tasks. In the example project, the MCU spends this time in Sleep Mode (EM1).The same principle is used on receive. When an RXDATAV interrupt is received, the Rx interrupt handler copies the incoming data to a receive queue.2.1 Kit ConfigurationThe development kit's on-board RS-232 line driver is used. This transceiver is normally disconnected from the MCU, so before it can be used, it must be enabled by software. To do this, the kit library functions are used. The kit libraries are included in the kit software packages that can be installed via Simplicity Studio. Documentation can be found in a sub-folder of the Energy Micro library installation folder. It is usually located at: [energymicro]\kits\EFM32GG_DK3750\bspdoc\html\index.html where [energymicro] is the Simplicity Studio data folder. The location of this folder is system dependent, and can be found through "Simplicity Studio->File->Browse Installed Files"The RS-232 transceiver is connected to UART1, location 2 on the EFM32.2.2 InstructionsA serial cable and terminal emulator software is required to try this example. On Windows, the OpenSource terminal Tera Term can be used.First, connect a serial cable between a computer and the 9-pin RS-232 connector on the development kit. Configure the serial port as follows•Baud rate = 115 200•Data bits = 8•Parity = none•Stop bits = 1•Flow control = nonebefore opening a connection with the terminal emulator.One should also configure the terminal emulator to handle new line in the same way as the SW example.In Tera Term the proper configuration is to use LF on receive and CR+LF on transmit. If this can't be configured on the chosen emulator, the example can of course be altered to match the emulator settings.When connected, start typing. After entering some characters, press '.' which is predefined as a "termination character" causing the MCU to echo the contents of the RX queue back out on the UART.2.3 TransmitTransmit is handled by two functions: uartPutData() and UART1_TX_IRQHandler().uartPutData() copies data to send into a transmit queue. The queue is implemented as a circular buffer.The data is copied into the queue starting at the write index (wrI). When finished, the pending byte counter is updated. Finally the TX interrupt for the UART is enabled.UART1_TX_IRQHandler() reacts when the TXBL interrupt goes high, signalling that the UART transmit buffer is empty. When this happens, one byte is copied from the read index (rdI) position in the TX queue into the UART transmit buffer. The read index is updated, and the pending byte counter is decremented.If the transmit queue becomes empty, the TXBL interrupt is disabled.2.4 ReceiveIn the same way, receive is also handled by two functions: UART1_RX_IRQHandler and uartGetData.UART1_RX_IRQHandler()reacts on the RXDATAV interrupt, meaning that the UART RX buffer contains valid data. When this happens, the incoming byte is copied from the UART RX buffer into the RX queue. The queue write index (wrI) is updated, and the pending byte counter is incremented. The IRQ handler will also disable the TXBL interrupt if the transmit queue becomes empty.uartGetData() pulls a number of bytes from the receive queue. The copy starts at the read index (rdI).When data is copied, the read index is updated and the pending byte counter is decremented.Also, for the sake of the example, the RX interrupt handler checks if the received byte is a predefined termination character.3 Revision History3.1 Revision 1.032013-09-03New cover layoutRemoved unnecessary read of IF in TX IRQ Handler3.2 Revision 1.022013-05-08Added software projects for ARM-GCC and Atollic TrueStudio.3.3 Revision 1.012012-11-12Adapted software projects to new kit-driver and bsp structure.3.4 Revision 1.002012-06-28Initial revision.A Disclaimer and TrademarksA.1 DisclaimerSilicon Laboratories intends to provide customers with the latest, accurate, and in-depth documentation of all peripherals and modules available for system and software implementers using or intending to use the Silicon Laboratories products.

Technical Note 483: Accessing UI Context and Non UI Context Object InstancesBackgroundThis document describes how Siebel applications instantiate objects to support the user interface (UI) and how these objects can be accessed from a script to implement business functions. It also describes how objects can be created "out of the UI context" to perform actions that are not immediately reflected in the UI.A good understanding of the difference between UI and non-UI context objects allows developers to instantiate objects in the right way depending on the business needs.1. UI Context objectsUI Context object instances are automatically created and destroyed by the Siebel application to support the rendering of a view.When a view is displayed in the UI, a business object instance is created in the UI context. Business component instances are created in the UI context for each applet in the view.All operations performed on a UI context object will be immediately reflected in the UI.For example:If bc has been instantiated in the UI context, the following eScript code will perform a requery in the current view and the UI will be affected by the query.Last Modified:3 October 2003Area(s):Siebel VB/eScript/Browser Script/COM Release(s):V7 (Enterprise)Database(s):All Supported Databases App Server OS(s):All Supported Platforms Latest release tested against:V7 (Enterprise)Keywords:UI context ActivateFieldbc.ClearToQuery();bc.ExecuteQuery();An operation like the example listed below will change the field "Name" in the UI and the user will immediately notice that this field has been updated.bc.SetFieldValue ("Name", "New Name" );Note: Operations that require the UI to be updated need to be performed using UI-context objects.1.1. Accessing UI context objectsSiebel applications provide methods to access UI objects from browser scripts and server scripts. The examples provided in this document assume that the language selected for server scripts is eScript.To access the business object in the UI context, the following methods are available:Application.ActiveBusObject, Buscomp.BusObject.Example:To access a business component in the UI context, the following methods are available:Application.ActiveBusComp, Applet.BusObject, BusObject.GetBusComp.Example: (code in Account Entry Applet PreInvokeMethod browser event)(*) ActiveBusComp is only supported in browser script1.2. Accessing field values from UI context business components.In order to access a field using .GetFieldValue method, the field needs to be activated.In browser scripting, only those fields being displayed in the view are activated. The exception to this rule is ID field which is always active and can be retrieved.In server scripting, the following fields can be retrieved from a UI-context buscomp:z System fields, like Id, Created, Created Byz Fields exposed in the UIz Fields with Force Active property = Truez Fields with Link Spec property = TrueIMPORTANT: Do not use ActivateField method to activate a field in a UIcontext business component. This may cause some unwanted sideeffects.2. Non-UI Context objectsNon UI context objects are created by code. The instances are non-visual. That is, they have no associated UI components. When a non UI context object is used to perform certain task, the result is not noticed by the user in the current view.Non UI context business components are used to perform tasks involving other business components that are not shown in the UI.When the current record is instantiated and modified in the UI context, a warning message appears which indicates that the current record has been modified by either another user or a process running out of the UI context. In order to see the new values of the fields the user may refresh the record by executing a query."The selected record has been modified by another user since it was retrieved."The following examples require the use of a Non-UI Context business component:z Invisibly querying a BC that is visible in the UI.{Querying data in a BC without the user seeing any change in the applet(s){Process many records in the backgroundz Using a BC in a different BO contextA business component is needed that represents the child/detail records for a parent/master other than thecurrent parent/master (Uses a different link)2.1. Accessing Non UI context objectsNon UI context business objects and business components can be created from server scripts using themethods: Application.GetBusObject and BusComp.GetBusComp .For example:var BO = TheApplication().GetBusObject("Opportunity");var OppBC = BO.GetBusObject("Opportunity");var ActBC = BO.GetBusComp("Action");GetBusObject is not supported in browser script. However, it is possible to call an applet or buscomp method that has been implemented in server scripting from a browser script.2.2. Accessing field values from Non UI context business componentsIn order to access a field using .GetFieldValue method, the field needs to be activated.In server scripting, the following fields can be retrieved from a Non UI-context buscomp: z System fields, like Id, Created, Created Byz Fields with Force Active property = Truez Fields with Link Spec property = Truez Fields that have been activated in code using ActivateField methodFor example:var ActBC = BO.GetBusComp("Action");ActBC.ClearToQuery();ActBC.ActivateField("Status");ActBC.ActivateField("Date Modified");…ActBC.ExecuteQuery();If (ActBC.FirstRecord()){var sStatus = ActBC.GetFieldValue("Status");…}IMPORTANT : Use ActivateField method BEFORE executing a query orcreating a new record using NewRecord. DO NOT use ActivateFieldAFTER executing the query or after a NewRecord.。
