LAN 10/100 ETHERNET PORT
EXPBUS
The instrument is equipped with a Ethernet Lan 10/100 Auto-MDI/MDIX port.
For the connection can be used a data cable straight or crossover.
Note: the port is not a PoE (Power over Ethernet = device power supply via the Lan port)
type. The connection of the device to a PoE port is anyway accepted. The power supply
anyway must be always provided by an external power supplier.
EXPBUS PORT
The ExpBus port, confi gurable via Ethernet port on web pages:
- uses a multicast communication rated at 250kb/sec with collision management
- max cable length : 10 meters
- manages up to 16 modules (but technically can manage up to 126)
- uses the UTP cable, 4 wires used:
2 for the power supply at 9 Vdc
2 for the bidirectional communication
The modules will also power supply the ExpBus port
The cable must be connected in in-out modality (multidrop) as per the RS485 Bus.
