*Setting this dial has no effect or purpose if the unit is set to use the
external clock.
†These data-rate settings are not supported by the standard A/S2W SHM.
If you need to transfer data at one of these speeds, call Black Box
Technical Support for a special quote on a unit that will.
**These settings (popular speeds for direct computer-to-computer
communication) do not work properly unless the A/S2W SHM
communicates with the DTE asynchronously (DIP Switch Position 1 set to
ON).
