SYD
FIBRE OPTIC LINE DRIVER

FEATURES:

  • Duplex RS232 standard core diameter fibres
  • Data control and clock lines supported. Clock lines generated or may be an input.
  • DC TO 64.kdbs per second
  • Asynchronous/synchronous
  • Pressed steel housing for EMI and RFI resistance.

    • TECHNICAL DESCRIPTION:

    Model SYD Fibre Optic Line Drivers are used in pairs to extend RS232 links via a Fibre Optic cable. The applications include longer RS232 links than can be obtained by copper conductors, data security from physical tampering and RFI admissions, data protection from environmental, noise and earth loop.
    The Model SYD supports modem control signals RTS, CTS, DSR, DTR and DCD. It also supports clock generation and will receive a clock up to 64kdbs. Synchronous data rates are selected internally by a switch. All data lines are RS232 compatible and power may be supplied either on pin 9, or via an external jack.
