UX-A255U 3. Operational description CHAPTER 5. CIRCUIT DESCRIPTION Operational descriptions are given below: • [1] Circuit description When a document is loaded in stand-by mode, the state of the document sensor is sensed via the 1 chip fax engine (SCE214V). With depression of the START key in the off-hook state, transmission takes place. Then, the procedure is sent out from the modem and the motor is rotated to move the document down to the scan line.

UX-A255U 4) External RAM and ROM [2] Circuit description of control PWB Moveable and programmble size external SRAM memory of up to 1 MB, DRAM memory of up to 4 MB, and ROM of up to 2 MB can be directly connected to the SCE214V. By using an external address decoder, the size of SRAM and/or ROM can be extened. The ROM stores all the program object code. 1. General description Fig. 2 shows the functional blocks of the control PWB, which is composed of 4 blocks.
