MVME712A I/O 转换模块 VME处理器模块

【产品详情】

特征：

• 4 个 25 引脚多协议 EIA-232-D 串行端口

MVME712M是摩托罗拉MPU VME模块、VME处理器模块、嵌入式控制器和单板计算机（SBC）系列处理器模块的I/O转换模块。该MVME712M与 MVME147、MVME1600、MVME162、MVME2600、MVME167、MVME2700、MVME177、MVME3600 MVME4600兼容。MVME712M用作处理器模块与其外围设备之间的接口。该模块的目的是提供后面板行业标准连接器，以简化外部客户电缆要求。

P2 适配器组合件在 VMEmodule MPU 连接处将 I/O 信号和接地从机箱背板上的 P2 连接器路由到MVME712M。MVME712M将信号路由到四个串行端口，前面板上有四个行业标准 DB-25 连接器。串行端口可以通过 MVME 712M 上的跳线排列配置为 EIA-232-D DTE 或 DCE。MVME712M前面板还具有一个以太网端口、一个 SCSI 端口和一个打印机端口。此外，MVME712M将 EIA-232-D 端口 2 信号路由到内部调制解调器。

MVME712M需要使用 P2 适配器板，该适配器板不包括在内。P2 适配器板的功能包括：
• 允许 SCSI 电缆连接到其他 SCSI 设备和/或通过扁平带状电缆连接到MVME712M的连接器 • SCSI 终端电阻器安装在插座中，用于电缆末端或电缆
配置
中间 • P2 适配器上的端接器电源从连接器 P2 上的 +5 伏直流电开发， 和 P1 适配器
上的熔断 （2 A） • 将 EIA-232-D 端口、打印机端口、SCSI 和以太网信号连接到MVME712M的连接器

Features:

Four 25-pin multi-protocol EIA-232-D serial ports

The MVME712M is an I/O conversion module for MOTOROLA's MPU VME module, VME processor module, Embedded controller, and Single-board Computer (SBC) family of processor modules. The MVME712M is compatible with MVME147, MVME1600, MVME162, MVME2600, MVME167, MVME2700, MVME177, MVME3600 and MVME4600. The MVME712M serves as the interface between the processor module and its peripherals. The module is designed to provide rear panel industry standard connectors to simplify external customer cable requirements.

The P2 adapter assembly routes the I/O signal and ground from the P2 connector on the chassis backplane to the MVME712M at the VMEmodule MPU connection. The MVME712M routes signals to four serial ports, with four industry-standard DB-25 connectors on the front panel. The serial port can be configured as EIA-232-D DTE or DCE via the jumper arrangement on the MVME 712M. The MVME712M front panel also has an Ethernet port, a SCSI port, and a printer port. In addition, the MVME712M routes the EIA-232-D port 2 signal to the internal modem.

The MVME712M requires the use of a P2 adapter board, which is not included. The functions of P2 adapter board include:

• Connectors that allow SCSI cables to be connected to other SCSI devices and/or to the MVME712M via flat ribbon cables • SCSI terminal resistors are installed in sockets for cable ends or cables
