DFR-3000 maintenance CD-ROM
(Part No. J-6409-130-A)
Procedure
(1) Extend the board, on which the PLD to be
programmed again is mounted, using an extension
board.
Extend the DPR-139, EN-139, and IF-752 boards
using extension board EX-621.
Extend the CN-1886 board using extension board EX-
680.
(2) Connect the parallel port of a PC and the program
download connector on the board, on which the PLD
to be programmed again is mounted, using a
ByteBlasterMV cable.
The download connectors on each board are as
follows:
DPR-139 board: CN701 (A-6)
EN-139 board: CN1900 (A-6)
IF-752 board:
CN901 (A-2)
CN-1886 board: CN202 (D-3)
(3) Insert the DFR-3000 maintenance CD-ROM into a PC,
install the download program (MAX PLUS II) of CD-
ROM, and then activate.
(4) Download the PLD program required for the PLD to
be programmed again.
For more information on the downloading, refer to the
manual supplied for the DFR-3000 maintenance CD-
ROM.
1-4-4. Caution on Replacement of DPR-139
Board
The microcomputer (IC708) on the DPR-139 board stores
the data for setting serial numbers. The data of serial
numbers set before replacement is lost when the DPR-139
board and microcomputer (IC708) are replaced. Therefore,
when replacing the DPR-139 board and microcomputer
(IC708), set the serial numbers again.
