GJR2923100R1工控卡件,ABB使用速度
通電后，調(diào)試端口的波特率可以通過以下方式重新配置：使用197Bug調(diào)試器的端口格式（PF）命令。注：為了實現(xiàn)之間的高波特率串行通信197Bug和終端要工作，終端必須做一些握手的形式。如果正在使用的終端沒有通過CTS線路進(jìn)行硬件握手，然后必須進(jìn)行XON/XOFF握手。如果用戶收到亂碼消息和缺少字符，則用戶應(yīng)檢查確保XON/XOFF握手已啟用的終端。
GJR2923100R1工控卡件4.如果需要連接設(shè)備（如主機系統(tǒng)和/或串行打印機）連接到其他EIA-232-D端口連接器（標(biāo)記為串行MVME712X轉(zhuǎn)換模塊上的端口2、3和4），連接如上文步驟3所述，安裝適當(dāng)?shù)碾娎|并配置端口。通電后，可以通過編程重新配置這些端口MVME197LE CD2401串行控制器芯片（SCC），或使用197Bug PF命令。注意，MVME197LE還包含一個并行端口。使用平行線帶有MVME197LE的設(shè)備（如打印機）將其連接到“打印機”通過MVME712X轉(zhuǎn)換模塊在P2處的端口。請參閱MVME197LE、MVME197DP和MVME197SP單板計算機一些可能的連接圖的程序員參考指南。然而，您也可以使用諸如MVME335之類的模塊來進(jìn)行并行處理端口連接。
5、接通系統(tǒng)電源。197Bug執(zhí)行一些自檢并顯示調(diào)試器提示“197 Bug>”（如果197Bug處于Board模式）。然而，如果ENV命令將197Bug置于系統(tǒng)模式，系統(tǒng)執(zhí)行自檢并嘗試自動啟動。請參閱ENV和MENU命令。它們列于表4-1中。如果置信度測試失敗，則在出現(xiàn)第一個故障時中止測試遇到。如果可能，將顯示適當(dāng)?shù)南?，并控制然后返回菜單。自動腳印Autoboot是包含在197Bug中的一個軟件例程，用于提供引導(dǎo)操作系統(tǒng)的獨立機制。這個autoboot例程按指定順序自動掃描控制器和設(shè)備直到找到包含引導(dǎo)介質(zhì)的有效可引導(dǎo)設(shè)備或列表筋疲力盡的如果找到有效的可引導(dǎo)設(shè)備，則會從該設(shè)備啟動起動。控制器掃描順序從最低的控制器開始檢測到的邏輯單元號（LUN）為檢測到的最高LUN。（參見附錄B中的默認(rèn)LUN）。通電時，Autoboot啟用，并提供驅(qū)動器和控制器遇到的數(shù)字有效，將在系統(tǒng)控制臺：
After power-up, the baud rate of the debug port can be reconfigured by
using the Port Format (PF) command of the 197Bug debugger.
Note In order for high-baud rate serial communication between
197Bug 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 the user gets garbled messages
and missing characters, then the user should check the
terminal to make sure XON/XOFF handshaking is enabled.
4. If it is desired 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 3 above.
After power-up, this(these) port(s) can be reconfigured by programming
the MVME197LE CD2401 Serial Controller Chip (SCC), or by using the
197Bug PF command.Note that the MVME197LE also contains a parallel port. To use a parallel
device, such as a printer, with the MVME197LE, connect it to the “printer”
port at P2 through an MVME712X transition module. Refer to the
MVME197LE, MVME197DP, and MVME197SP 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.
5. Power up the system. 197Bug executes some self-checks and displays the
debugger prompt “197-Bug>” (if 197Bug is in Board Mode). However, if
the ENV command has put 197Bug in System Mode, the system performs
a self test and tries to autoboot. Refer to the ENV and MENU commands.
They are listed in Table 4-1.
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.Autoboot
Autoboot is a software routine that is contained in the 197Bug 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. (Refer to
Appendix B for default LUNs).
At power-up, Autoboot is enabled, and providing the drive and controller
