G3 Receive Mode
Figure A2.3 shows the G3 receive picture signal route.
In the G3 mode, the high-speed picture signal arriving from the telephone line at L1 and L2 of NCU passes through
the transformer T1 and the amplifier and is input to the MODEM as "R" signal. After demodulation by modem, the
picture data is sent to IOGA4 (CPU). The IOGA4 (CPU) performs the picture data processing (decode) for this
picture data and stores into the DRAM. Then, the stored picture data is again written into DRAM (as a page memory)
by the picture processing control of IOGA4 (CPU). When the data for one page has been stored in the DRAM, the
data is read out from the DRAM and sent to IOGA4. The picture data is converted into a signal data by the printer
control of IOGA4 and transferred to the LED print head for printing as HDATA 0.
