Writing And Rewriting Pld Internal Data - Sony TRINITRON BVM-A14F5M Service Manual

1-4. Writing and Rewriting PLD Internal
Data
The BVM-A14 is equipped with a PLD (Programmable
Logic Device) which can be written and rewritten using the
e-Production (EPR) method.
When replacing the following parts or upgrading the PLD
version, contact your local Sony Sales Office/Service
Center.
n
The part number of the PLD (or the ROM for the PLD)
presented in "Spare Parts" is that of the part with no data
written.
When you need to replace any part, write data in the steps
on the right.
For the PLD whose program operates on the externally
connected ROM, when a part in the PLD is defective, if
you replace only the defective part, you do not have to
rewrite the data.
About e-Production
. When writing or rewriting the PLD internal data,
1. standard tools (cables) can be used.
2. standard software (PLD Download Tool) can be
used.
. The PLD internal data is managed on the Sony database
server as a Project file (E_xxx_xxx_xx_xx).
. Standard connector (EPR connector) for writing PLD
internal data on the board is equipped. "EPR" is dis-
played on the board.
