OKIFAX 5700/5900 G - 22. Basic Operation2.1 Supported FunctionsThe PC loading functions described herein are as follows. Functions equivalent to those usedin the existing HSLS (High Speed Loading System) are supported.1. Default data area loading function2. Language area loading function3. Flash memory area program loading function (The flash memory on the ISDN optionboard is included.)These PC loading functions are supported only when the OS used on the PC side is eitherMS-DOS Ver. 6.0 or above or PC-DOS Ver. 6.0 or above.2.2 Differences from HSLSIt must be noted that PC loading through the Centro cable is different in the following points ascompared with loading in the HSLS:(1)While transition to the PC loading process is judged according to the presence/absence ofthe HSLS board, transition to PC loading is possible by detection of memory error occur-rence and manual key operation this time.(2)The header information is added anew to cope with the addition of the loading program asone of the loading data.(3)There is no special application in this PC loading unlike the HSLS. Loading is performed byloading data output to the parallel port by means of a binary specification (copy/b).(4)In the case of the HSLS, returning to normal standby state will not occur so long as theHSLS board is installed. In this system, on the other hand, the normal standby state is setautomatically upon detection of the end of loading data by means of the header data.(5)The cause of the error is displayed by the corresponding code upon occurrence of a hashNG or other error. For the code, see “6. List of Error Causes and Corresponding Codes.”2.3 G4 PC LoadingThe G4 board PC loading data transferred from the PC through the bi-Centro cable is tempo-rarily stored in the DRAM in the MFP main unit. Next, this data is transferred to the G4 boardthrough the dual port RAM (hereafter called the DPRAM).G4 board program transferred through the bi-Centro interfaceG4 board program transferred through the DPRAMMFPmain unit G4BoardPCMFP system
