Modbus parameters configuration
The 8-position dip-switch is used to change the baud rate, the address on the
MPNC006 and the stop and parity bit.

Address (ID module)
The address is set using switches
3
to
8
, so the valid addresses are 1 to 63.
It is important that the address setting is carried out before the
MPNC006 is turned on because one of the first operations carried out at
the turn-on is the reading of the DIP status and if it detects that the
address is zero it signals the error condition
the four flashing LEDs
.
The address is coded according to the following table:
S-3 S-4 S-5 S-6 S-7 S-8
