B&R 7DO135.70模拟量输出模块，7DO135.70使用配置教程

为了实现之间的高波特率串行通信172Bug和终端要工作，终端必须做一些握手的形式。如果正在使用的终端没有通过CTS线路进行硬件握手，则必须这样做XON/XOFF握手。如果你收到乱码信息缺少字符，则应检查终端以确保已启用XON/XOFF握手。4.如果您想连接设备（如主机系统和/或串行打印机）连接到其他EIA-232-D端口连接器，连接适当的电缆并按照详细说明配置端口上述步骤3中。

B&R 7DO135.70模拟量输出模块通电后，您可以重新配置这些端口通过编程MVME172LX Z85230串行通信控制器（SCC），或使用172Bug PF命令5.EPROM/Flash标头J20必须设置为配置3，并且J20针脚5-6、8-10和9-11之间的跳线。这为512K x 8个EPROM。6、接通系统电源。172Bug执行一些自检，并如果固件在板上，则显示调试器提示172 Bug模式但是，如果ENV命令将172Bug置于系统模式，系统执行自检并尝试自动启动。请参阅环境和菜单命令（表4-3）。如果置信度测试失败，则在出现第一个故障时中止测试遇到。如果可能，将显示适当的消息，并且控件然后返回菜单。7、初始安装后使用MVME172LX前，设置使用以下命令行结构的日期和时间：例如，以下命令行启动实时时钟并将日期和时间设置为1999年9月7日上午10:37：172 Bug>SET 0907991037Autoboot是包含在172Bug中的软件例程闪存/可编程只读存储器提供独立的启动机制操作系统。自动启动例程自动扫描控制器和设备，直到有效的可引导设备找到包含启动介质或列表已用尽。如果有效的可引导找到设备后，从该设备启动。控制器扫描序列从最低控制器逻辑单元号（LUN）开始检测到检测到的最高LUN。控制器、设备及其LUN见附录D。通电时，Autoboot启用（前提是驱动器和遇到的控制器编号有效）

In order for high-baud-rate serial communication between

172Bug and the terminal to work, the terminal must do some

form of handshaking. If the terminal being used does not do

hardware handshaking via the CTS line, then it must do

XON/XOFF handshaking. If you get garbled messages and

missing characters, then you should check the terminal to

make sure XON/XOFF handshaking is enabled.

4. If you want to connect devices (such as a host computer system

and/or a serial printer) to the other EIA-232-D port connectors,

connect the appropriate cables and configure the port(s) as detailed

in step 3 above. After power-up, you can reconfigure these port(s)

by programming the MVME172LX Z85230 Serial

Communications Controllers (SCCs), or by using the 172Bug PF

command.

5. The EPROM/Flash header J20 must be set to configuration 3, with

jumpers between J20 pins 5-6, 8-10, and 9-11. This sets it up for

512K x 8 EPROMs.

6. Power up the system. 172Bug executes some self-checks and

displays the debugger prompt 172-Bug> if the firmware is in Board

mode.

However, if the ENV command has put 172Bug in System mode,

the system performs a self-test and tries to autoboot. Refer to the

ENV and MENU commands (Table 4-3).

If the confidence test fails, the test is aborted when the first fault is

encountered. If possible, an appropriate message is displayed, and

control then returns to the menu.

7. Before using the MVME172LX after the initial installation, set the

date and time using the following command line structure:

For example, the following command line starts the real-time clock

and sets the date and time to 10:37 a.m., September 7, 1999:

172-Bug> SET 0907991037Autoboot is a software routine that is contained in the 172Bug

Flash/PROM to provide an independent mechanism for booting an

operating system. This autoboot routine automatically scans for controllers

and devices in a specified sequence until a valid bootable device

containing a boot media is found or the list is exhausted. If a valid bootable

device is found, a boot from that device is started. The controller scanning

sequence goes from the lowest controller Logical Unit Number (LUN)

detected to the highest LUN detected. Controllers, devices, and their LUNs
