    Description

    Async/Sync Fiber Optic Modems, ST, DB25 Male


    Quick Facts

  3. V.54 loopback and V.52 BERT pattern generator.
  4. Internal, external, or received clocking in sync mode.
  5. Draws power from the RS-232 interface.
  6. Carrier options for “Continuously On” or “Controlled by RTS.”
    　
  7. Half- or full-duplex operation

    8. 　

    Further Details

  8. Point-to-point communication up to 2 miles (3.2 km).
  9. DIP switches enable 11 user-selectable data rates.
  10. Manage delay time, operation mode, and carrier control settings—plus determine word length.
    In sync or async mode, half- or full-duplex operation, these modems are fast for simple data transmission—a full 38.4 kbps. You also get the distance you need at nearly any point-to-point, campus-based application—up to 2 miles (3.2 km).

    External DIP switches enable you to set the speed for 1 of 11 variable data rates. You can also choose clocking methods (sync mode only) and determine word length. Plus, these units enable you to manage delay time, operation mode, and carrier control settings.

    You can perform diagnostics like V.54 loopback and a V.52 BERT pattern generation to determine line and data integrity.
