Each instrument in the RS485 network is univocally identified by an address ranging within 1

No more than one transmitter with the same address can be present in the
same
network
.
Before connecting the base unit to the RS485 network, configure address and Baud Rate (see
chapter "
HD35AP… base unit
configuration
” of the software
online help
). The communication
parameters in the PC/PLC must be the same as those set in the base unit.
