GE Fanuc / VMIC VMIVME-5531 VMEbus 光纤中继器链路是一种高性能且易于使用的方法，可通过光纤电缆将两个或多个 VME 系统连接在一起。Repeater Link 是一个双板组，它允许驻留在一个 VME 机箱中的 VME 从属 I/O 板由驻留在另一个机箱中的 VME 主站控制。通常，VME主设备所在的VME机箱称为主机箱，而VME从属板则位于辅助机箱中。两块板组配置了一块指定用于主机箱的板，而另一块板指定用于辅助机箱。主 VME 机箱可以通过在星形配置中使用多个 REPEATER 链路与多个辅助机箱进行通信。

该链接是软件透明的。主机箱中的任何 VME 主设备都可以访问（读取或写入）辅助机箱中的任何从设备板。辅助机箱中只允许使用不中断的从属板。当 VME 主设备（通常是 CPU 板）寻址辅助机箱中的任何板时，会自动建立主机箱和辅助机箱之间的链路。

每当主机箱中的主设备发出 VME 读/写周期时，该周期都会重复到辅助机箱。如果任何辅助机箱中的从属板响应该地址，则将在机箱之间进行数据传输（读取或写入），并且将向主机（在主机箱中）生成数据传输确认 （DTACK） 以完成循环。

链路由两块板（VMIVME-5531M 和 VMIVME-5531S）和两根电缆组成，使 VME 系统能够扩展到单个机箱之外。

位于 VMIVME-5531M 前面板上的链路复位开关允许 用户在不重置主机箱的情况下在辅助机箱中置位 SYSRESET （或多链路配置中的其他辅助机箱）。当 SYSRESET 为 在主机箱中置位，它将重复到所有辅助机箱。

VMIVME-5531M 和 VMIVME-5531S 都有一个双色 LED，它 指示链接的状态。当本地接收器达到 与远程发射器的锁相和帧同步。红色 LED 指示 链路未准备就绪，这可能是由于电缆损坏或接线错误， 远程机箱未通电，或链路损坏。LED 在 重置。

The VMIVME-5531L is the form, fit and function replacement of the VMIVME-5530

The GE Fanuc/VMIC VMIVME-5531 VMEbus Fiber Optic Repeater link is a high performance and easy to use method for connecting two or more VME systems together via fiber optic cables. The Repeater Link is a two-board group that allows a VME slave I/O board residing in one VME chassis to be controlled by a VME master residing in another chassis. Generally, the VME chassis where the VME master device resides is called the main chassis, and the VME slave board is located in the auxiliary chassis. The two board groups are configured with one board designated for the main box and the other board designated for the auxiliary box. The primary VME chassis can communicate with multiple secondary chassis by using multiple REPEATER links in a star configuration.

The link is software transparent. Any VME master device in the main box can access (read or write to) any slave device board in the secondary box. Only slave boards that do not interrupt are allowed in the auxiliary chassis. When the VME master device (usually the CPU board) addresses any board in the secondary case, a link between the main case and the secondary case is automatically established.

Whenever the primary device in the main box issues a VME read/write cycle, the cycle is repeated to the secondary box. If the slave board in any secondary chassis responds to this address, data is transferred (read or written) between the chassis, and a data transfer confirmation (DTACK) is generated to the host (in the main chassis) to complete the loop.

The link consists of two boards (VMIVME-5531M and VMIVME-5531S) and two cables, enabling the VME system to scale beyond a single chassis.

The link reset switch located on the front panel of the VMIVME-5531M allows the user to set SYSRESET in the auxiliary chassis (or other auxiliary chassis in a multi-link configuration) without resetting the main chassis. When SYSRESET is set in the main box, it will be repeated to all auxiliary boxes.

Both the VMIVME-5531M and VMIVME-5531S have a two-color LED, which indicates the status of the link. When the local receiver reaches phase-lock and frame synchronization with the remote transmitter. A red LED indicates that the link is not ready, which may be due to a damaged cable or miswiring, a remote chassis that is not powered on, or a damaged link. The LED is reset.
