REPLACING THE MAIN PCB
The SummaSign and SummaCut cutters manufactured since December 1995 have a different main
PCB from those manufactured before that date.
The boards on the new cutters have the logic for the head control on the same main PCB whereas
the parallel input is on an extra board. You can obtain this option by ordering part number 421-174.
The new type of boards are fully compatible with the old type of boards, the only difference being the
position of particular connectors, and certain parts, previously situated on the small PCB, that can
now be found on the main PCB.
The old type of boards can be exchanged for the new type of boards.
Summarizing, there are two types of main PCBs:
0
Type 1
: Main PCBs dating from before December
1
Type 2:
Main PCBs dating from after December 1995
