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.
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.
