6.5.1 DIP-Switch Setting
The only parameter you have to set to install the adapter into the system is the
Bus
I/O Address. Its possible values are set with four switches at the rear of the

Note:
The
on and off DIP-switch selections are set by switching them down and
up, respectively. The mapping is:
off = up
on = down
