BENTLY 128229-01 3500/42M加速度监测器模块
为了实现高波特率串行通信在177Bug和终端之间工作，终端必须进行某种形式的握手。如果终端使用时不会通过CTS线路，则必须进行XON/XOFF握手。如果你会收到乱七八糟的信息和丢失的字符，然后你应该检查终端以确保XON/XOFF握手已启用。8.如果您想连接设备（如主机系统和/或串行打印机）连接到另一个EIA-232-D端口连接器（上标记有串行端口2、3和4MVME712x转换模块），连接适当的按照上述步骤6中的详细说明连接和配置端口。
BENTLY 128229-01 3500/42M加速度监测器模块通电后，可以通过以下方式重新配置此（这些）端口：编程MVME177 CD2401串行控制器芯片（SCC），或使用177Bug PF命令。注意，MVME177还包含一个并行端口。使用具有MVME177的并行设备，如打印机，通过MVME712x将其连接到P2的“打印机”端口过渡模块。参考MVME177单板计算机程序员参考指南连接图。但是，您也可以使用模块例如用于并行端口连接的MVME335。9.在系统中安装任何其他必需的VMEmodules。10、更换机箱盖。11、将电源电缆连接到交流电源。12、打开设备电源。177Bug执行一些自检，并显示调试器提示“177Bug>”（如果177Bug处于板模式）。但是，如果ENV命令将177Bug置于系统模式，系统执行自检并尝试自动启动。参考ENV和中的调试器命令表中列出的菜单命令附录B.注意，当MVME177冷复位时，177Bug在系统模式下运行。使用环境（ENV）或菜单命令可以使177Bug在单板模式下运行。请参阅附录B中的调试器命令表。如果置信度测试失败，当第一个故障发生时，测试中止遇到。如果可能，将显示相应的消息，然后控制返回菜单。
In order for high baud-rate serial communication
between 177Bug 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.
8. 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 (marked SERIAL PORTS 2, 3, and 4 on the
MVME712x transition module), connect the appropriate
cables and configure the port(s) as detailed in step 6 above.
After power-up, this(these) port(s) can be reconfigured by
programming the MVME177 CD2401 Serial Controller Chip
(SCC), or by using the 177Bug PF command.
Note that the MVME177 also contains a parallel port. To use
a parallel device, such as a printer, with the MVME177,
connect it to the "printer" port at P2 through an MVME712x
transition module. Refer to the MVME177 Single Board
Computers Programmer's Reference Guide for some possible
connection diagrams. However, you could also use a module
such as the MVME335 for a parallel port connection.
9. Install any other required VMEmodules in the system.
10. Replace the chassis cover.
11. Connect power cable to AC power source.
12. Turn equipment power ON. 177Bug executes some selfchecks and displays the debugger prompt "177-Bug>" (if
177Bug is in Board Mode). However, if the ENV command
has put 177Bug in System Mode, the system performs a
selftest and attempts an autoboot. Refer to the ENV and
MENU commands listed in the Debugger Command Table in
Appendix B. Note that when the MVME177 comes up in a cold reset,
177Bug runs in System Mode. Using the Environment (ENV)
or MENU commands can make 177Bug run in Board Mode.
Refer to the Debugger Commands Table in Appendix B.
If the confidence test fails, the test aborts when the first fault
is encountered. If possible, an appropriate message displays,
and control then returns to the menu.
Refer to Appendix B for general information and operation of
the Debugger
