  • Supports up to 16 slave-only chassis per master
  • DIN-type I/O connectors
  • Double Eurocard form factor
  • Link includes one master board, one slave board, and a wide variety of cable length options
  • Supports 16-bit addressing
  • Supports 8-, 16-, and 32-bit data transfers
  • Supports the configuration of large I/O systems
  • Supports up to 1,000-ft cables
  • Differential line drivers and receivers provide ±7 V common-mode noise rejection
  • Multidrop capability reduces cost
  • Software transparent link
  • Slave chassis is placed in reset if master chassis is powered down or cables are disconnected

Abaco VME-5531L VMEbus Fiber-Optic Repeater Link 3U and 6U. No slave interrupts.

  • The VME-to-VME link consists of two boards and two fiber-optic cables (master board: 6U, slave board: 6U or 3U)
  • Form, fit, and function replacement for VMIVME-5530
  • Maximum 6,560 ft (2,000 m) fiber-optic cables
  • No EMI generated by cables
  • High-voltage isolation
  • High-noise immunity
  • Small cables
  • Advantages over standard repeaters
  • Total electrical isolation between VMEbus systems
  • Supports 16-, 24-, and 32-bit addressing (6U slave)
  • Supports 8-, 16-bit data, 16-, 24-bit address (3U slave)
  • Plug-and-play operation
  • Supports 8-, 16-, and 32-bit data transfers (6U slave)

Abaco VME-5532L VME Fiber-Optic Repeater Link with Slave Chassis System Controller

  • High performance, easy-to-use method of linking two or more VME systems together via fiber-optic cable
  • Provides 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 VME Systems
  • Maximum 6,500 ft(2,000m) 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
