RS-232C Command List
RS-232C Mode and the Memory Banks
Structure of the Memory Banks
The XC-555 is equipped with three Memory Banks
(Factory/A/B) to hold camera settings. Factory is “read
only,” holding the settings made when the camera was
shipped from the factory. A and B can be written to, as
well as read from, and the user utilizes these locations
to hold setting values, calling them up when needed.
When the camera is in operation, valid settings are
held in volatile memory. The user sends RS-232C
commands to change the camera settings, overwriting
the settings information held in these memory
locations.
Using the “Memory Save” command, setting
information can be written to either of the non-volatile
Memory Bank A or Memory Bank B locations.
Using the “Memory Load” command, the information
stored in Memory Banks Factory, A, or B, can be read
out.
When power to the camera turned on, the settings
information loaded with the most recent “Memory
Load” command is read out of memory, and used as
the current settings. (When the camera is shipped from
the factory, the information stored in the Memory
Bank Factory is set to be read out when power is
turned on.)
Settings made with the DIP switches on the side of the
camera or with the R/B adjustment volume are
recognized as the same as some of those held in the
Factory memory location. However, when “Memory
Load (Factory)” is carried out in RS-232C mode,
settings made with the DIP switches on the side of the
camera or with the R/B adjustment volume are
rendered invalid, and the settings are returned to those
made when the camera was shipped from the factory.
When the RS-232C switches hidden by the camera
cover are set to OFF, Memory Banks A and B are
disabled, so when power to the camera is turned on,
the camera starts up normally, using the settings stored
in Memory Bank Factory.
(This is the way the camera is shipped from the
factory.)
