BENTLY 1900/27位移監測器模塊，1900/27使用流程
如果您打算使用MVME172LX作為系統控制器，它可以必須占用最左邊的卡槽（槽1）。系統控制器必須在插槽1中才能正確啟動(dòng)總線(xiàn)授予菊花鏈并確保IACK菊花鏈驅動(dòng)器的正確操作。
–如果您不打算使用MVME172LX作為系統控制器，它可以占用任何未使用的雙高卡插槽。4.將MVME172LX滑入所選卡槽。確保模塊正確安裝在背板。
BENTLY 1900/27位移監測器模塊不要損壞或彎曲連接器針腳。5.用提供的螺釘將MVME172LX固定在機箱中，與橫向安裝軌道接觸良好，以將射頻發(fā)射。在機箱背板上，刪除中斷確認卡頭的（IACK）和總線(xiàn)授權（BG）跳線(xiàn)MVME172LX占用的插槽。將適當的電纜連接到MVME172LX面板EIA-232-D串行端口、SCSI端口和LAN的連接器以太網(wǎng)端口。–請注意，MVME172LX未配備某些電纜并且必須由用戶(hù)制作或購買(mǎi)。（摩托羅拉建議所有外圍連接使用屏蔽電纜盡量減少輻射。）、將外圍設備連接至電纜。9.在系統中安裝任何其他必需的VMEmodules。10、更換機箱蓋。11、將電源線(xiàn)連接到交流電源，然后轉動(dòng)設備通電。系統注意事項MVME172LX從P1和P2連接器中獲取電源在VMEbus背板上。P2還用于32位傳輸，并用于擴展尋址中的上8個(gè)地址行模式如果沒(méi)有主板，MVME172LX可能無(wú)法正常工作連接到VMEbus背板連接器P1和P2。MVME172LX是作為VMEbus主機還是作為VMEbus運行從機，配置為32位地址和32位數據（A32/D32）。但是，它在中所示的地址范圍內處理A16或A24設備第3章。系統中的D8和/或D16設備必須由MC68060/MC68LC060軟件。請參閱中的內存映射MVME172 VME嵌入式控制器程序員參考指南。
If you intend to use the MVME172LX as system controller, it
must occupy the leftmost card slot (slot 1). The system controller
must be in slot 1 to correctly initiate the bus-grant daisy-chain
and to ensure proper operation of the IACK daisy-chain driver.
– If you do not intend to use the MVME172LX as system
controller, it can occupy any unused double-height card slot.
4. Slide the MVME172LX into the selected card slot. Be sure the
module is seated properly in the P1 and P2 connectors on the
backplane. Do not damage or bend connector pins.
5. Secure the MVME172LX in the chassis with the screws provided,
making good contact with the transverse mounting rails to minimize
RF emissions.On the chassis backplane, remove the INTERRUPT ACKNOWLEDGE
(IACK) and BUS GRANT (BG) jumpers from the header for the card
slot occupied by the MVME172LX.
7. Connect the appropriate cable(s) to the MVME172LX panel
connectors for the EIA-232-D serial ports, SCSI port, and LAN
Ethernet port.
– Note that some cables are not provided with the MVME172LX
and must be made or purchased by the user. (Motorola
recommends shielded cable for all peripheral connections to
minimize radiation.)
8. Connect the peripheral(s) to the cable(s).
9. Install any other required VMEmodules in the system.
10. Replace the chassis cover.
11. Connect the power cable to the AC power source and turn the
equipment power ON.
System Considerations
The MVME172LX draws power from both the P1 and the P2 connectors
on the VMEbus backplane. P2 is also used for the upper 16 bits of data in
32-bit transfers, and for the upper 8 address lines in extended addressing
mode. The MVME172LX may not operate properly without its main board
connected to VMEbus backplane connectors P1 and P2.
Whether the MVME172LX operates as a VMEbus master or as a VMEbus
slave, it is configured for 32 bits of address and 32 bits of data (A32/D32).
However, it handles A16 or A24 devices in the address ranges indicated in
Chapter 3. D8 and/or D16 devices in the system must be handled by the
MC68060/MC68LC060 software. Refer to the memory maps in the
MVME172 VME Embedded Controller Programmer’s Reference Guide.
