MESSAGE "CFG ERROR"

During the set up operation a "CFG ERROR" message could appear. This means that

some wrong parameters are inserted.

* with RS-485 Master PUK activated

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.
