configuration change : 1800 w 92 is for CxT, UseACSWRack=1

Although the can10556 is 0, but Mark said that the item should be 1.
Follow the 6000 CxT's way (they use the same detection board).
so .....

2.2pr2 & pr3 (ow18,19) are changed simultaneously.
(because 2.2pr3 is the developement version - for adding modbus function)
