The GE Fanuc / VMIC VMIVME-5531 VMEbus Fiber-Optic Repeater Link is a high performance, yet easy-to-use method of linking two or more VME systems together via fiber-optic cable. The Repeater Link is a two board set which allows VME slave I/O boards residing in one VME chassis to be controlled by a VME master residing in another chassis. In general, the VME chassis in which VME masters reside is referred to as a primary chassis, while the VME slave boards reside in a secondary chassis. The two board set is configured with one board designated for the primary chassis while the other board is designated for the secondary chassis. A master VME chassis can communicate with several secondary chassis by using multiple REPEATER Links in a star configuration.
The link is software transparent. Any VME master in the primary chassis may access (read or write) to any slave board in the secondary chassis. Only non-interrupting slave boards are allowed in the secondary chassis. The link between the primary chassis and secondary chassis is automatically established when a VME master (typically a CPU board) addresses any board in the secondary chassis.
Any time a master in the primary chassis issues a VME read/write cycle, it will be repeated to the secondary chassis. If a slave board in any secondary chassis responds to that address, the data transfer (read or write) will occur between the chassis and a Data Transfer Acknowledge (DTACK) will be generated to the master (in primary chassis) to complete the cycle.
A link consists of two boards (VMIVME-5531M and VMIVME-5531S) and two cables which enable a VME system to be expanded beyond a single chassis.
A link reset switch located on the front panel of the VMIVME-5531M allows the user to assert SYSRESET in the secondary chassis without resetting the primary (or additional secondary chassis in multiple link configurations). When SYSRESET is asserted in the primary chassis it is repeated to all secondary chassis.
Both the VMIVME-5531M and VMIVME-5531S have a bi-color LED which indicates the status of the link. The LED is green when the local receiver has achieved phase-lock and frame synchronization with the remote transmitter. A red LED indicates that the link is not ready which may be due to damaged or miswired cables, unpowered remote chassis, or a damaged link. The LED is red momentarily during reset.
