3.6.2. Scaler
It is a counter with the GATE input for enabling the counter and the counter RESET input.
The counter has the programmable END_COUNT_LIMIT parameter; LIMIT can be set in
the 0 ÷ 1023 range; if LIMIT = 0, the scaler counts countinuously and produces an
END_CNT_PULSE every 1024 hits (each time ZERO is met); the scaler can be halt via
the RESET input. If END_COUNT_LIMIT = N (N
≠ 0), the scaler counts up to N hits, then
produces END_CNT_PULSE; if AUTORES is enabled, the scaler, after N hits, returns to
zero and can accept new hits to count, otherwise it halts.
3.6.3. Coincidence
It is a two input OR port. Since each input and output can be negated, it can operate also
as AND. The Coincidence output can be connected either to other units input or to an
output connector.
3.6.4. Input/Output Register
The output signals can be programmed via an Output Register, while the input signals
can be monitored via an Input Register.
