Basic Operation

2.1

Supported Functions

The PC loading functions described herein are as follows. Functions equivalent to those used
in the existing HSLS (High Speed Loading System) are supported.
1. Default data area loading function
2. Language area loading function
3. Flash memory area program loading function (The flash memory on the ISDN option
board is included.)
These PC loading functions are supported only when the OS used on the PC side is either
MS-DOS Ver. 6.0 or above or PC-DOS Ver. 6.0 or above.
2.2 Differences from HSLS
It must be noted that PC loading through the Centro cable is different in the following points as
compared with loading in the HSLS:
(1)While transition to the PC loading process is judged according to the presence/absence of
the 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 as
one of the loading data.
(3)There is no special application in this PC loading unlike the HSLS. Loading is performed by
loading 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 the
HSLS board is installed. In this system, on the other hand, the normal standby state is set
automatically 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 hash
NG or other error. For the code, see "6. List of Error Causes and Corresponding Codes."

G4 PC Loading

The 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 board
through the dual port RAM (hereafter called the DPRAM).
