The A-160-2 module is essentially a frequency divider for clock, gate, and trigger signals. The module divides an incoming signal in accordance with the variations listed on each of its seven outputs, which range from 1/2 of the original signal all the way down to 1/128.
Three different sets of dividing factors, selected by a three-position switch at the front panel: power of two: 2, 4, 8, 16, 32, 64, 128; prime numbers: 2, 3, 5, 7, 11, 13, 17; integer: 2, 3, 4, 5, 6, 7, 8
Two output modes, selected by a two-position switch at the front panel: Gate mode: outputs act like the outputs of typical binary dividers; Trigger mode: in this mode the outputs are AND-wired with the clock signal (i.e. the clock pulsewidth affects the pulsewidth of the outputs)
Clock edge type selected by a jumper on the pc board: positive: the rising edge of the clock signal triggers the state change of the outputs; negative: the falling edge of the clock signal triggers the state change of the outputs
Reset behaviour by two jumpers on the pc board: level triggered: the level at the Reset input triggers the Reset; edge triggered: the edge of the signal at the Reset input triggers the Reset; positive: a high level (> 2.5V) or the rising edge at the Reset input triggers the Reset; negative: a low level (< 1 V) or the falling edge at the Reset input triggers the Reset
Output polarity selected by a jumper on the pc board: positive: non-inverted outputs; negative: all seven outputs are inverted
