The PCA9541 is a 2-to-1 I2C-bus master Selector designed for high reliability dual masterI2C-bus applications where system operation is required, even when one master fails orthe controller card is removed for maintenance. The two masters (for example, primaryand back-up) are located on separate I2C-buses that connect to the same downstreamI2C-bus slave devices. I2C-bus commands are sent by either I2C-bus master and are usedto select one master at a time. Either master at any time can gain control of the slavedevices if the other master is disabled or removed from the system. The failed master isisolated from the system and will not affect communication between the on-line masterand the slave devices on the downstream I2C-bus.

對象放置(Object Placement)
ISIS支持多種類型的對象,每一類型對象的具體作用和功能將在下一章給出。雖然類型不同,但放置對象的基本步驟都是一樣的。
放置對象的步驟如下(To place an object:)
1.根據(jù)對象的類別在工具箱選擇相應(yīng)模式的圖標(biāo)(mode icon)。
2. Select the sub-mode icon for the specific type of object.
2、根據(jù)對象的具體類型選擇子模式圖標(biāo)(sub-mode icon)。
3、如果對象類型是元件、端點、管腳、圖形、符號或標(biāo)記,從選擇器里(Selector)選擇你想要的對象的名字。對于元件、端點、管腳和符號,可能首先需要從庫中調(diào)出。
4、如果對象是有方向的,將會在預(yù)覽窗口顯示出來,你可以通過點擊旋轉(zhuǎn)和鏡象圖標(biāo)來調(diào)整對象的朝向。
5、最后,指向編輯窗口并點擊鼠標(biāo)左鍵放置對象。對于不同的對象,確切的步驟可能略有不同,但你會發(fā)現(xiàn)和其它的圖形編輯軟件是類似的,而且很直觀。
選中對象(Tagging an Object)
用鼠標(biāo)指向?qū)ο蟛Ⅻc擊右鍵可以選中該對象。該操作選中對象并使其高亮顯示,然后可以進(jìn)行編輯。

SENTINEL 的加密狗lic生成工具方法如下
1.copy a870.sentinel to windows\system32 folder.
2.run Emulator Utility and then press install button and close the utility.
3.run wechoid.exe, Selector must be 1e or 1c
4.then run LicGen and use Selector and code from wechoid.exe w/o 0x, it will make a license for that pc
