Recorder Module - Datascope Accutorr Plus Service Manual

2.2.3 Recorder Module

Accutorr Plus Recorder module provides the interface from the LED/CPU module to the
recorder. This module is strictly an output device for the Accutorr Plus. Data is written
to the module via DMA and is then routed out to the recorder.
Software Control
There are no software requirements on this board. The microcontroller for this board's
functions are located on the LED/CPU board.
Hardware Functions
Recorder Driver Circuit Board
This circuit takes all control instructions from the LED/CPU board and provides
printhead drive decoding, paper drive motor control logic decoding, printhead "home
switch" position sensing and pulse width modulated oscillator for print head drive.
Recorder Transport and Print Assembly
This mechanical assembly has no active electronic components. A paper drive motor,
print head shuttle and print head position sensor report to the Recorder Driver circuit
board.
