Remark: As the Sync-input has a weak pull-up to 5V, your trigger source definitely needs to be able to
sink that current in order to pull the input down to Gnd. So as a trigger source, you can use an open
collector transistor output, that pulls to ground or a push pull output. The input can support 24V, but
the trigger threshold is always at approximately 2V. The trigger occurs on the rising edge, that means
when the external pulldown transistor releases the input or when the pushpull drives to 5V.
Wait for trigger – signal characteristics to Analog Out
The sensor stops after the current data telegram is transmitted and
goes into a standby mode.
The last transmitted analog value persists until the next exposure
(also see TRG command).
2.7.4 External analogue converter box connection
The 8 pins round connector is used for external analogue converter box connection. This option can
be added to the CHRocodile C in order to obtain an analogue output. Also it is possible to add up to 2
encoder-input using this external analogue converter box connection.
The incremental encoder-input makes it possible to precisely assign the measurement point and axis
position without additional hardware. The CHRocodile C can manage with 2-axis encoders if the
optional analogue converter box is connected to the CHRocodile C 8-pins mini-DIN connector.
For an exact distance measurement it is necessary for every measurement value to be assigned to the
exactly correct spatial coordinates. This data must be recorded in the system and transferred to the
evaluation processing unit over the internal interface. To accomplish this, the sensor must be
equipped with the analogue box accessory.
