Internal Data
This unit uses the PLD (Programmable Logic Device) that
supports the e-Production (EPR) system to write and
rewrite the internal data.
If the part listed below needs to be replaced or to be
upgraded, contact your Sony Sales Office/Service Center.
n
The part number of PLD (or ROM for PLD) in which data
is not written yet, is shown in "Section 1. Spare Parts" of
the MAINTENANCE MANUAL Volume 2.
Therefore, if part replacement is required, write the data by
the following procedure.
In the case of the PLD type that runs on the program stored
in external ROM, data needs not to be written only by
replacing the part if the specific PLD only is defective.
e-Production system has the advantages shown
below.
. To write/rewrite the PLD internal data:
1. The standard fixture (cable) can be used.
2. The standard software (PLD Download Tool) can be
used.
. The PLD internal data is controlled in the Sony Database
Server under the name Project file (E_xxx_xxx_xx_xx).
. The printed circuit board is equipped with the standard
connector (EPR connector) to write the PLD internal
data. The indication "EPR" is shown on the printed
circuit board.
