GE VMIVME-5532L Slave Chassis System Controller
DESCRIPTION
The VMIVME-5532 Link is a high-performance, yet easy-to-use method of linking two or more VMEbus systems together via fiber-optic cable. The Repeater Link is a two-board set which allows VMEbus slave I/O boards residing in one VMEbus chassis to be controlled by a VMEbus master residing in another chassis. In general, the VMEbus chassis in which VMEbus masters reside is referred to as a master chassis, while the VMEbus slave boards reside in a slave chassis. However, the VMIVME-5532 also allows a local VMEbus master to work in a slave chassis for local control, thus providing multimaster in the slave chassis.
FEATURES
• High-performance, easy-to-use method of linking two or more VMEbus systems together via fiber-optic cable
• Can provide system controller function in the slave chassis
• A local master is allowed in slave chassis
• Software transparent allows direct communication from master chassis to slave chassis with no software overhead (unidirectional link control with bidirectional data transfers). This mode allows plug-and-play operation.
• Register enable allows operation as described above, but includes registers in short I/O space dealing with slave chassis multimaster operation
• Supports 8-, 16-, and 32-bit data transfers
• Supports 16-, 24-, and 32-bit addressing
• Total electrical isolation between VMEbus systems
• Maximum 6,560 ft (2,000 m) fiber-optic cables
• Advantages over standard repeaters
— Small cables
— High-noise immunity
— High-voltage isolation
— No EMI generated by cables
• The VME-to-VME link consists of two boards and two fiber-optic cables
