using a single button to control a tortoise switch machine on the Button Board

Setting CV548 to 1 will cause pushbuttons connected via the optional Button Board to
to "toggle" the switch machine output. Each press of a button will alternate the switch
position. Setting CV548 = 1 enables the toggle option. CV548 = 0 disables it.
CV548 is "global" to the Switch8-Mk2, meaning it will affect all button commands coming
from the Button Board. (Factory default= 0)

To use one N.O. pushbutton make sure the global toggle option is set to on first.Use the accessory address of the first channel. Set CV548 to 1 for that accessory address.Then connect the two wires from the pushbutton as follows: One wire connects to GND. The other wire can connect to either the N or the R terminal for that channel.

That’s it.
