Receiver setup: PPS and Event In

Background Information
PPS
PPS stands for pulse per second. If configured, the receiver sends out an electric pulse at a specified interval time. This can be
used e.g. to activate another device. The pulse is sent out via the dedicated PPS port. For further information go to Ports &
Pins Assignments: GR25.
Event Input
Event input is possible via serial port 2. The event input interface allows for the detection of pulses which are sent from external
devices connected to the receiver. The pulses can be recorded in the receiver and then later can be superimposed on the
processed kinematic data. The positions where the events took place can be interpolated in LGO.
Events logged during real time operation can also be exported to an ASCII file using an appropriate format file.

Description
Check to activate the output of a periodic pulse, uncheck to deactivate.
Select the rate at which pulses are to be output. Ranges from 0.05s to 20.0s.
Select to output a pulse starting with a rising or a falling edge.
Rising edge: Generates a normally low, active high pulse with the rising edge as the
reference.
Falling edge: Generates a normally high, active low pulse with the falling edge as the
reference.
Description
Activates the detection and logging of events being received on serial port 2.
Select the polarity to use the rising or falling edge of the incoming pulse as trigger in
order to record an event.
Accepts Default or User defined calibration values for the particular receiver.
Available if Bias internal is set to User. Sets the calibration value in nanoseconds for
the receiver.
Sets a calibration value in nanoseconds according to the external event device and
cable being used.
If two or more events take place during the time defined in seconds, the first event
will be recorded. Enter 0 to accept all events. The shortest recording time is 0.05 s.
User input. Records up to 80 characters of data with the event record.
