To replace an I/O board
The procedure described here is for
machines with more than one I/O board. On
machines with only one I/O board, that
board can be replaced without any need for
this procedure.
If there is more than one I/O circuit board, the
processor must know whether the new circuit
board is I/O board 1, I/O board 2 or I/O board 3.
For this programming you need:
1. A portable PC with Windows 98, NT, ME or
2000.
2. The correct cable for connecting the PC to the
CPU board.
3. A service program for the PCU which you can
run on a PC. The program is called
G3000" and can be used for numbering the I/
O boards correctly, amongst other things.
This program can be ordered from the
supplier.
Instructions:
1. Order a copy of the program
you do not have it already. Programs can be
supplied on diskette or via E-mail.
2. If you have not already installed it, install the
program "CMM
3. Switch off the machine's main power switch.
