DMC08A Board (Optional)
The DMC08A, which is a DMS interface (I/F) board, outputs data to the E I/F. It also per-
forms normalization (Sk/Gp conversion) and pixel density conversion processing, and
accumulation to and reoutput from the DMS
For image processing, it contains a 128K-word (24-bit) SRAM and a 1M-word (16-bit)
DRAM.
The data that is image-processed by the IMG board is written to the HDD and then read
from the HDD for output to the E I/F at high or standard resolution.
High resolution or standard resolution is judged in an image transfer reservation response
from the output destination.
This information is stored for each DMS after boot-up.
It should be noted that when a break status is detected on the line, the E I/F clear its
memory.
