FRAP DTE Port
Clocking Mode
-
Provides the DTE clock phase inversion option. Most applications do not require inverting the DTE clock, but occasionally, shifting the DTE clock 180 degrees can solve out-of-phase timing problems on the DTE link.
-
Range: Normal or Inverted
-
Timing
-
Defines the DTE timing source. The timing source may either be obtained from the DTE (Loop-1) or from an internal clock crystal (Loop-2). If a problem with DTE timing occurs, or if you are uncertain which timing to use, configure the unit for Loop-2 timing.
-
Range: Loop-1 or Loop-2
