When power to the camera turned on, the settings on “Factory” is loaded automatically. (The AGC, Shutter, W.balance, and VBS/ YC settings made using the DIP switches or made using the R/B adjustment volume are enabled. )

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.)
