BENTLY 1900/27位移监测器模块，1900/27使用流程

如果您打算使用MVME172LX作为系统控制器，它可以必须占用最左边的卡槽（槽1）。系统控制器必须在插槽1中才能正确启动总线授予菊花链并确保IACK菊花链驱动器的正确操作。

–如果您不打算使用MVME172LX作为系统控制器，它可以占用任何未使用的双高卡插槽。4.将MVME172LX滑入所选卡槽。确保模块正确安装在背板。

BENTLY 1900/27位移监测器模块不要损坏或弯曲连接器针脚。5.用提供的螺钉将MVME172LX固定在机箱中，与横向安装轨道接触良好，以将射频发射。在机箱背板上，删除中断确认卡头的（IACK）和总线授权（BG）跳线MVME172LX占用的插槽。将适当的电缆连接到MVME172LX面板EIA-232-D串行端口、SCSI端口和LAN的连接器以太网端口。–请注意，MVME172LX未配备某些电缆并且必须由用户制作或购买。（摩托罗拉建议所有外围连接使用屏蔽电缆尽量减少辐射。）、将外围设备连接至电缆。9.在系统中安装任何其他必需的VMEmodules。10、更换机箱盖。11、将电源线连接到交流电源，然后转动设备通电。系统注意事项MVME172LX从P1和P2连接器中获取电源在VMEbus背板上。P2还用于32位传输，并用于扩展寻址中的上8个地址行模式如果没有主板，MVME172LX可能无法正常工作连接到VMEbus背板连接器P1和P2。MVME172LX是作为VMEbus主机还是作为VMEbus运行从机，配置为32位地址和32位数据（A32/D32）。但是，它在中所示的地址范围内处理A16或A24设备第3章。系统中的D8和/或D16设备必须由MC68060/MC68LC060软件。请参阅中的内存映射MVME172 VME嵌入式控制器程序员参考指南。

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.
