PTQ-PDPMV1接口模块,PROSOFT使用方法教程
符合FCC的底盘上进行了测试，符合A类设备的要求。FCC合规性在以下条件下实现：所有外部输入/输出端口上的屏蔽电缆。2、通过金属外壳连接至接地的电缆屏蔽连接至导电模块前面板的连接器。3、导电底盘导轨接地。这提供将屏蔽连接到接地的路径。4、前面板螺钉正确拧紧。对于最小射频发射，必须满足上述条件实施；如果不这样做，可能会危及FCC包含模块的设备的合规性。说明MVME177是基于MC68060微处理器。

❏ VMEbus到/来自本地总线的非DMA编程访问界面
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:
