Each channel has overflow indication with ability to count beyond overflow. Any channel overflowing results in a LAM condition. Channels may be reset individually or as a group. One or more TCLK events may be used to reset all of the scalers.
Channel count inputs are provided at both the front of the module and the rear I/O connector. Front count inputs may be either NIM or TTL convention. The rear count inputs are TTL and can accommodate positive or negative edge inputs. Internal one-shots may be employed to filter input signals that exhibit excessive leading and/or falling edge oscillations.
External gates for each channel are provided at the rear I/O connector. Gates may also be developed from the TCLK interface and may be applied to individual scaler channels.
Version 1 is the base module without any modifications
The inputs are configured for NIM input.
PALS 33310A and 33315A are standard among the different versions
Version 2 is the base module without any modifications
The inputs are configured for TTL input.
PALS 33310A and 33315A are standard among the different versions
Version 3 Probably never existed

This module takes four MSBs from a 169 MDAT receiver and generates energy-proportional gates for the 333 scaler for the purpose of scaling aborted charge with beam energy.
