Holdover Signal -> the output is high when the unit is in holdover mode
Reference 1 Signal -> the output is high when the unit is using the reference 1
Reference 2 Signal -> the output is high when the unit is using the reference 2
Reference 3 Signal -> the output is high when the unit is using the reference 3
Reference 4 Signal -> the output is high when the unit is using the reference 4
Reference 5 Signal -> the output is high when the unit is using the reference 5
Free-run Signal -> the output is high when the unit is in the free run mode
Reset -> input signal, reset the module
Ground
External Reference 5 Input -> the input signal from reference 5
Alarm signal -> the output is high when there is an alarm in the module.
Revertive Input-> to set revertive mode (low), to disable revertive mode set the pin high.
Control Input 1 -> the external input for selecting mode of the unit – see table above.
