VPL-CS2/CX1
3-6. Memory
Memory structure of VPL-CS2/CX1 series is based on the
VPL-CS1 and it is composed of the following eight
memory blocks.
1. Set memory
2. Status memory
3. Channel memory
4. Chroma memory
5. W/B memory
6. Reso memory
7. Gamma memory
8. Uniformity memory
CPU internal ROM : 256 kbyte Flash Memory
CPU internal ROM : 16 kbyte
External NVM memory : 8 kbyte EEPROM
(BA mounted IC202)
When the power plug is connected to the power line
(Standby status), all data inside the internal ROM are
written into the NVM (Nonvolatile Memory). When the
power is turned to on, required data for the current picture,
such as status memory data, etc., are selected, and they are
written into the internal RAM. At this time, the gamma
memory data and uniformity memory data which newly
provided in this series are not writing into the internal
RAM but they will be transferred to the register inside the
device directly.
When adjustment is carried out, adjustment data are
written into the NVM automatically (items on the user
mode) or by the trigger of memory operation (items on the
service mode and special service mode).
But, each values of gamma memory and uniformity
memory does not adjust from the OSD but can only adjust
by the RS232C communications.
Adjustable items (W/B and Device Adjust) of the service
mode and special service are memorized into the NVM by
the memory operation. At the same time, the factory preset
(adjusted) data are all eliminated from the memory.
