PTQ-PDPMV1接口模塊,PROSOFT使用方法教程
符合FCC的底盤上進行了測試，符合A類設(shè)備的要求。FCC合規(guī)性在以下條件下實現(xiàn)：所有外部輸入/輸出端口上的屏蔽電纜。2、通過金屬外殼連接至接地的電纜屏蔽連接至導(dǎo)電模塊前面板的連接器。3、導(dǎo)電底盤導(dǎo)軌接地。這提供將屏蔽連接到接地的路徑。4、前面板螺釘正確擰緊。對于最小射頻發(fā)射，必須滿足上述條件實施；如果不這樣做，可能會危及FCC包含模塊的設(shè)備的合規(guī)性。說明MVME177是基于MC68060微處理器。

FCC Compliance
The MVME177 was tested in an FCC-compliant chassis, and meets
the requirements for Class A equipment. FCC compliance was
achieved under the following conditions:
1. Shielded cables on all external I/O ports.
2. Cable shields connected to earth ground via metal shell
connectors bonded to a conductive module front panel.
3. Conductive chassis rails connected to earth ground. This
provides the path for connecting shields to earth ground.
4. Front panel screws properly tightened.
For minimum RF emissions, it is essential that the conditions above
be implemented; failure to do so could compromise the FCC
compliance of the equipment containing the module.
General Description
The MVME177 is a double-high VMEmodule based on the
MC68060 microprocessor. The MVME177 has:
? 4/8/16/32/64/128/256 MB of ECC-protected DRAM
? 8KB of static RAM and time of day clock (with battery
backup)
? Ethernet transceiver interface
? Four serial ports with EIA-232-D interface
? Four tick timers
? Watchdog timer
? 4 MB of Flash memory
? Two EPROM sockets
? SCSI bus interface with DMA? One parallel port
? A 16/A24/A32/D8/D16/D32/D64 VMEbus master/slave
interface
? 128KB of static RAM (with optional battery backup), and
VMEbus system controller.
The I/O on the MVME177 is connected to the VMEbus P2
connector. The main board is connected through a P2 transition
board and cables to the transition boards. The MVME177 supports
the following transition boards:
