終止通信單擊菜單欄上的通信，然后單擊關(guān)閉通信端口。系統(tǒng)會詢問您是否要將設(shè)置保存到EEPROM。有人問這個問題即使未對DECS-100設(shè)置進(jìn)行任何更改。當(dāng)執(zhí)行關(guān)閉命令時（使用是或否將設(shè)置保存到EEPROM），與DECS-100的通信終止。如果你選擇要退出BESTCOMS（單擊菜單欄上的文件，然后退出），無需首先關(guān)閉通信，仍然有機(jī)會將設(shè)置保存到EEPROM。嵌入式固件嵌入式固件是控制DECS-100動作的操作程序?qū)⒐碳鎯υ诳赏ㄟ^RS-232重新編程的非易失性閃存中通信端口。當(dāng)使用更新版本。
更新固件DECS-100功能的未來增強(qiáng)可能需要固件更新。DECS-100可通過執(zhí)行以下步驟更新嵌入式固件。在DECS-100的后部RS-232接頭和之間連接通信電纜PC的適當(dāng)通信端口。
單擊BESTCOMS菜單欄上的DECSLoad
然后單擊上載嵌入式軟件。如果菜單選擇變灰，您需要關(guān)閉DECS-100通信。參考有關(guān)關(guān)閉DECS-100通信的信息，請參閱“終止通信”小節(jié)。單擊上載嵌入式軟件時，會顯示一個對話框（圖5-21），其中建議您需要斷開DECS-100發(fā)電機(jī)和總線連接，并將DECS-00設(shè)置保存在文件中在繼續(xù)固件上傳之前。固件上傳可能會替換一些用戶調(diào)整的設(shè)置具有出廠默認(rèn)設(shè)置。單擊“是”繼續(xù)軟件上載。單擊“是”時，通信啟動屏幕（圖5-4）出現(xiàn)。選擇電腦的活動通信端口，然后單擊初始化按鈕BESTCOMS從DECS-100獲取配置設(shè)置并保存所有設(shè)置。
當(dāng)設(shè)置保存完成時，圖5-22的DECS-100嵌入式程序加載器出現(xiàn)。將出現(xiàn)另一個對話框，其中包含制作說明

TERMINATING COMMUNICATION
DECS-100 communication is terminated by clicking on Communications on the menu bar, and clicking
Close Comm Port. You are asked if you want to save the settings to EEPROM. This question is asked
even if no changes were made to the DECS-100 settings. When you execute the Close command (with a
Yes or No to save settings to EEPROM), communication with the DECS-100 is terminated. If you choose
to exit BESTCOMS (by clicking File on the menu bar and then Exit) without first closing communication,
you are still given the opportunity to save the settings to EEPROM.
EMBEDDED FIRMWARE
Embedded firmware is the operating program that controls the actions of the DECS-100. The DECS-100
stores firmware in nonvolatile flash memory that can be reprogrammed through the RS-232
communication port. It is not necessary to replace EPROM chips when replacing the firmware with a
newer version.
Updating the Firmware
Future enhancements to DECS-100 functionality may make a firmware update desirable. DECS-100
embedded firmware can be updated by performing the following steps.Connect a communication cable between the rear RS-232 connector of the DECS-100 and the
appropriate communication port of your PC.
2. Click DECSLoad on the BESTCOMS menu bar and click Uploading Embedded Software. If this
menu selection is grayed out, you'll need to close DECS-100 communication. Refer to the
Terminating Communication subsection for information about closing DECS-100 communication.
When Uploading Embedded Software is clicked, a dialog box (Figure 5-21) is displayed that advises
you to disconnect the DECS-100 generator and bus connections and save the DECS-100 settings in a file
before proceeding with firmware uploading. Firmware uploading may replace some user-adjusted settings
with factory-default settings. Click Yes to proceed with software uploading. When Yes is clicked, the Communication Initiation
screen (Figure 5-4) appears. Select the active communication port for your PC and click the Initialize
button. BESTCOMS obtains the configuration settings from the DECS-100 and saves all settings.
When the saving of settings is complete, the DECS-100 Embedded Program Loader of Figure 5-22
appears. Another dialog box will appear with instructions for making
the password change. Click the OK button and type a new
password (8 alphanumeric characters, maximum) in the
"Enter your new password" field.
Press the Enter or Tab key on your keyboard to advance the
cursor into the field labeled "Re-enter your new password".
Type the new password again to confirm the changed
password and press the Enter key. When the Enter key is
pressed, the new password is enabled and a dialog box
appears to remind you to keep your password in a secure
location.
