1. DAQ setup (centralized topology)
Architecture:
Star topology with a central gateway + Ethernet switch and power supply unit (PSU).
Each DAQ device connects individually to the gateway.
Characteristics:
Single connectivity kit (gateway + switch + PSU) required for the installation.
Maximum capacity: ~10 DAQ units per gateway.
All traffic from DAQ devices is aggregated and routed through the gateway.
Requires individual Ethernet connections from each DAQ to the central switch.
Implications:
Hardware scaling requires additional gateways once the 10-device limit is reached.
Higher cabling complexity due to multiple runs to the central switch.
2. NOVAQ setup (daisy-chain topology)
Architecture:
Linear/daisy-chain network topology.
NOVAQ units are connected sequentially to each other via built-in Ethernet switching.
Characteristics:
No central gateway required.
Modem required for external connectivity:
4G or Wi-Fi.
Integrated Ethernet configuration within each NOVAQ unit.
Power supply requirement: approximately 1 PSU per 3–4 NOVAQ units.
Implications:
Simplified cabling (devices connect to the next device instead of a central switch).
Modular scalability by extending the chain with additional NOVAQ units.
Reduced external networking hardware due to embedded networking capabilities.
Notice Both DAQ and NOVAQ devices are powered over Ethernet (PoE); therefore, the Ethernet cable length cannot exceed 75 m.
