5. DIL Switch Settings
The DIL switch located on the top site of the unit provides encoder settings and customer-
specific settings of the desired operation modes.
Changes of switch settings will become active only
after the next power-up cycle!
SSI Resolution:
3 OFF, 4 OFF : not valid
3 ON, 4 OFF : 25 bit encoder
3 OFF, 4 ON : 21 bit encoder
3 ON, 4 ON : 13 bit encoder
Set Default:
OFF: Unit loads default settings with every power-up cycle
ON : No loading of default settings upon power-up.
Update Mode
ON: Update of parallel output in a fixed preset time pattern
OFF: Update of parallel output after every SSI telegram
Pin 25 Function:
OFF: Pin 25 indicates that output data is stable (LOW)
ON : Pin 25 is a normal data output (bit 25 or error bit)
SSI Code
OFF: Gray Code
ON: Binary Code
SSI Mode:
OFF : Slave Operation
ON : Master Operation
Pin 25 Function:
OFF : Pin 25 = Error bit output
ON : Pin 25 = normal data output (bit 25)
1 2 3 4 5 6 7 8
The switch settings shown in the example are suitable for Master operation of a 25 bit SSI
encoder with Gray coded output. The parallel output operates with equidistant update times
and pin 25 is used to indicate valid and stable output data.
