SWD
-2 is OFF the serial will be available on connector
J6
(RS232 or RS485 on the basis of
SWD
-3 with the baud rate selected by

On the DIPOT board there is a dip-switch selector that can be used to implement up to 16 DIPOT boards
on the same RS485 bus line, switch the UP inputs with the DOWN inputs and manage the writing of the
remote Modbus registers.
Modbus Address
: The max. number of DIPOT boards on the same RS485 bus line is 16. The
SWE dip lets you select the physical address of the DIPOT boards from a value of 1 to a value of
16 by suitably modifying the switches from 1 to 4 as in the following table
Selecting Modbus address:
Note that address 1 is obtained with all the switches (1 to 4) OFF.
