终止通信单击菜单栏上的通信，然后单击关闭通信端口。系统会询问您是否要将设置保存到EEPROM。有人问这个问题即使未对DECS-100设置进行任何更改。当执行关闭命令时（使用是或否将设置保存到EEPROM），与DECS-100的通信终止。如果你选择要退出BESTCOMS（单击菜单栏上的文件，然后退出），无需首先关闭通信，仍然有机会将设置保存到EEPROM。嵌入式固件嵌入式固件是控制DECS-100动作的操作程序将固件存储在可通过RS-232重新编程的非易失性闪存中通信端口。当使用更新版本。
更新固件DECS-100功能的未来增强可能需要固件更新。DECS-100可通过执行以下步骤更新嵌入式固件。在DECS-100的后部RS-232接头和之间连接通信电缆PC的适当通信端口。
单击BESTCOMS菜单栏上的DECSLoad
然后单击上载嵌入式软件。如果菜单选择变灰，您需要关闭DECS-100通信。参考有关关闭DECS-100通信的信息，请参阅“终止通信”小节。单击上载嵌入式软件时，会显示一个对话框（图5-21），其中建议您需要断开DECS-100发电机和总线连接，并将DECS-00设置保存在文件中在继续固件上传之前。固件上传可能会替换一些用户调整的设置具有出厂默认设置。单击“是”继续软件上载。单击“是”时，通信启动屏幕（图5-4）出现。选择电脑的活动通信端口，然后单击初始化按钮BESTCOMS从DECS-100获取配置设置并保存所有设置。
当设置保存完成时，图5-22的DECS-100嵌入式程序加载器出现。将出现另一个对话框，其中包含制作说明
密码更改。单击“确定”按钮并键入新的密码（最多8个字母数字字符）“输入新密码”字段。
按键盘上的Enter键或Tab键前进光标进入标记为“重新输入新密码”的字段。再次键入新密码以确认更改的密码
密码并按回车键。当输入键为按下，将启用新密码并显示一个对话框
显示提醒您以安全的方式保存密码地方
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.
