The following check are performed for the optional RAM.
The following process is performed for memory address to be
checked.
The following check are performed for the optional RAM.
The following process is performed for memory address to be
checked.
PASS1: memory data save
PASS2: Data "00H" write
PASS3: Data "00H" read and comparison, data "55H" write
PASS4: Data "55H" read and comparison, data "AAH" write
PASS5: Data "AAH" read and comparison
PASS6: Memory data restore
PASS2: Data "00H" write
PASS3: Data "00H" read and comparison, data "55H" write
PASS4: Data "55H" read and comparison, data "AAH" write
PASS5: Data "AAH" read and comparison
PASS6: Memory data restore
If a compare error is found in the check sequence from PASS1 to
PASS6, error print (error code E1) is performed. If there is no error
found to the end of the last address, the operation is completed
normally.

A single byte image of the RAM data to be transmitted is divided into
a high order 4 bits and low order 4 bits and converted into ASCII
code. Then, the image of the memory is sent in the following format:
a high order 4 bits and low order 4 bits and converted into ASCII
code. Then, the image of the memory is sent in the following format:

the ER-02FD, the memory size of the receiving unit must the
same as or greater than the sending unit.

2) Master reset the receiving ER-A570.
3) Match the baud rate of the transmitter with the receiver using
JOB#995 in the SRV mode.
4) Connect loader cable (QCNW-7578RCZZ or ER-A5CB) between
ER-A570s.
5) Set the receiving ER-A570 ready to receive.
6) Start the sending ER-A570.
