16.1 P2 row A/C pin assignments
The P2 connector of the SIS3820 (in 64 channel or clock module configuration) has
connections on rows A and C to feed the second set of 32 inputs to the module or for
operation as backplane clock distributor for the SIS330x digitizer family. This implies, that
the module can not be operated in a VME slot with a special A/C backplane, like VSB e.g..
The pin assignments of P2 rows A/C of the SIS3820 for both scaler and clock module is
shown below. 32 channel versions do not make use of P2 rows A/C.
