DEVICE CONFIGURATION
The device can communicate with the serial line only if a serial address is selected. This
setting has to be done with DIP-SWITCH. The serial address has to be arranged only in
case of using the serial line, if the programming procedure will be made by HOTKEY
this procedure can be skipped. There are 31 address available as explained by the
