The PR-612 parallel output register is a single width Camac module which contains two 24 bit registers to hold and transfer data from the crate dataway to an external device. The outputs are available on two 31 pin connectors mounted on the front panel or a single 52 pin connector mounted on the rear panel. An optional front panel LED display is available for visual display of both registers.
Data outputs are negative true, open collector drivers capable of sinking 48 milliamps (37 milliamps if LED display is used), at +5 volts. Should high current be required, register may be ordered with 280 ma sinking capability.
Data outputs are set by use of write command F(16). Data from the write lines are clocked into the register addressed at S1. Registers may be read onto the dataway with an F(O) command.
A negative output pulse for each channel is provided to indicate
when its register has been updated.
