The DMM acts as an interface between the RS485 network
and the Dupline network. Any DMM is identified by a master
address and a modbus device address that contains different
values (see below). The rules of the system are the following:
1. It is not allowed to put two GP3496s with the same mod-
bus device address on the same MOXA
2. It is not allowed to have two GP3496s in the entire system
with the same master address. The master address 0 is allowed. Therefore, when all DIP-
SW are in 0 position it shall be read as master address 0.
Master address The jumpers are mounted on the PCB by default, so the bits
This address is selected by using ALL 6 DIP-switches in the 6-8 are generally read as 0.

ers) mounted on the PCB. The master address is read as: Modbus device address
Please note that the master address and the modbus device
Bit 15-9= 0 address are two different things here.

Bit 2 = 1 - if dipswitch4 is ON it must be interpreted by the GP3496 as modbus address 16,
Bit 1 = 1 - if dipswitch5 is ON so the GP3496 must answer telegrams sent to device 16, and
