I ROM data transfer

TEST MODE

When replacing front-end (A1), this function is used to transfer E2PROM data (ROM correction, security and other data) to front-end (A1) to
E2PROM of to mother unit (X34) used for saving data, and, after completing replacement of front-end (A1), to recover data from the E2PROM
of the mother unit (X34) and for saving data to the new front-end (A1). Refer to ROM data transfer processes on the next page for details on
front-end (A1) replacement procedures and on the data to be transferred.

ROM DATA TRANSFER PROCESSES

When replacing front-end (A1) of mother unit (X34-), or when
adding or replacing ROM correction (program correction
with ROM IC (1010)), the following activities are required.

I Overview

When replacing front-end (A1) in the model where ROM cor-
rection and security data have been written into E2PROM,
included in the front-end (A1) pack, the transfer function of
the E2PROM data itself in the replaced front-end (A1) is re-
quired.

This function in the above system configuration is used to
allow for complete replacement of the front-end at any ser-
vice center.

I Overview of specifications

Procedures for replacement are as follows: To install the
E2PROM to the mother unit (X34) and replace front»end (A1)
with new front-end after copying the data in the E2PROM
(such as ROM correction data and other data) in the front-
end (A1) to the mother unit (X34-) by operating the system,
and then copy the data (such as ROM correction data and
other data) into the mother unit to the E2PROM of the front»
end (A1), operating the main body.

Tuner adjustment data was inserted during the tuner pack
manufacturing, and data will not be transferred because
front-end (A1) is built-in.

In addition, tuner adjustment data for new front-end (A1) is
supplied as a service part in which data was inserted.

I Operation procedure

Operation procedure is different depending on the condi»
tions. Proceed with the appropriate operation procedure
depending on the specific condition.

1. In case of replacing front-end (A1) without an applicable
ROM correction.

2. In case of replacing front-end (A1) with an applicable
ROM correction.

3. in case of applying new ROM correction at the same
time when front-end (A1) is replaced. (No ROM correc-
tion has been carried out.)
