Switch Configuration
Some configurations can be made using the four DIL switches mounted in the end-plate of
the module.
The DIL Switches are only read at power-up, and change the volatile configuration of the
module. The non-volatile configuration is not changed. DIL Switch settings allow the factory
configuration to be restored, testing functions, and some simple back-to back configurations.
If you want the module to start up in the same way each time, you will need to leave the
switches in the same setting. If you are using the switches to do temporary changes, then you
should change the switches back to the zero position after powering up.
