SSW7000 | 6-2
Internal Connections
NOTE!
The SSW7000 CC11 hardware is identical to that of the CFW-11 CC11. However, the firmware
version and the PLD code are different. Because of the different PLD code, it is not possible to
transform a CFW-11 board into an SSW7000 one by
simply updating the firmware. Only the
CC11xy.Sz boards are adequate for the SSW7000. If an SSW7000 firmware version is flashed into
a board with a CFW-11 PLD, then the fault “Incompatible PLD Firmware” will appear on the display.
