Infrastructure Management

1. Modbus 485 and/or SNMP
Communications

i. Default of 16 devices in an

RDU module (Can be all

Modbus 485, or all SNMP, or
a Mix).

ii. Can be extended to have

additional 16 devices more
by purchasing licenses to
make the total to a maximum
of 32.

iii. Each COM port can support a

maximum of 4 daisy chained
connection (need to be same
device) BUT maximum Per

device will still be 32 devices.

Note: If communicating to a 3rd part
will need to get SNMP MIB File for SNMP
communication and Modbus Reference Library
for Modbus communication to build driver. This
will incur additional charges.
