Changing a CV on an Accessory or Accessory Address

You will need to know the accessory address of the item or channel you need to change.
Let's say you have the accessory address/channel on an NCE SW8 or Digitrax DS64 set to accessory address 1234
The device will need to be put in programming mode first.

To change a CV for accessory address 1234 on an NCE system: 
Press the PROG / ESC key until you see OPS PROG ACCY CV
press enter
put in the accessory address of the item that needs the CV modified. In our case, that is 1234.
Press enter, and put in the CV number you want to modify
press enter
put in the new CV value you need to change, then press enter.
Use the PROG/ESC key to exit back to the main screen when you are done.
***Note that some accessories might need a reboot/power cycle for changes to take effect.
