6.4.1 Firmware memory IC6, EPROM 128 Kbytes
The firmware is programmed into a 27C010-type EPROM. This EPROM has a PLCC-package.
For exchanging the EPROM you need a special PLCC extracting tool. The position of the EPROM
is shown in figure 13.
While inserting the EPROM, keep care that the diagonal edge of the package fits the diagonal
side of the socket. Press the EPROM into the socket by a slight pressing with your finger until you
feel it snaps in.
The program memory IC6 is programmed with the firmware of the two Collamat 8600 and 9100.
The firmware makes out the connected interfaceboard by a specific code of the board.
If the EPROM is extracted with the wrong tool, the socket may be damaged.
6.4.2 The LCD-Display
The LCD-display has four lines with 20 character types. It shows all the user information and the
labeler conditions. The backlight illumination can be turned on and off by the microcontroller. The
illumination gives a good reading of the informations of the display in dark environment.
6.4.3 Adjusting the contrast
For this adjustment the little trimmer RP1 on the component side is used. (See also figure 12).
This trimmer must be operated with a special screwdriver for SMD components. If you use an-
other kind of tool, the trimmer can be damaged. Never apply force to the trimmer !
6.4.4 Exchanging a defective LCD
First all four fixing screws of the LCD must be removed. Then all the 16 solder points of the con-
nector X2 must be unsoldered from the soldertin. The new LCD is now inserted over the 16 con-
tact pins and fixed with the four fixing screws. Before you resolder all the pins, watch the
parallelism of the LCD to the front foil.
Before you change the LCD, watch the guarantee regulations. For broken
LCD's no guarantee is given! Unauthorized soldering on assemblies while
guarantee time, lapses the guarantee.
