Setup key 
Using the Setup key, you can 
call the M203 menu, which 
appears in the M51 display. 
Using the Softkeys 
you can get to pages #1 and #2 
Slot Selection 
If a second M203 (M200) is 
connected to the M51 Link 
output, a different address must 
be assigned through the slot 
selection so that both M203s don’t 
occupy the same slot address. 
This would cause errors. In the 
case of a double assignment, 
neither of the two M203s would be 
shown in the M51 Version list.
Slot addresse: #11 or #12 
Important: 
Only one M203 may be connec-
ted to the M51 Link for the 
address selection. You should 
separate the one M203 from the 
M51 Link while assigning the 
address to the other. If the 
addresses are correctly set, both 
M203s (M200) will appear in the 
M51 version list. 
You will find further information 
on this topic in the M51 manual 
in the Introduction chapter 
under the Version function.
