4.1 Modbus parameters configurations
The 8th position dip-switch is used to change the baud rate, the address on the
MPNE1001 and the stop and parity bit.

4.1.1 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
MPNE1001 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 LED LINK
flash.
The address is coded according to the following table:
S-3 S-4 S-5 S-6 S-7 S-8

To set 1 on the DIP switch, the switch must be set to the ON side.
