board
Table 25: Ethernet port connection
The Data Logger board provides a standard RJ45 connector (IEEE 802) for 10/100 Ethernet connection
(100Base-TX, 10Base-T). The layout of the pins is the same as that found on each network board serving
the PC.
The pin layout is as follows:
Pin

1
TD+
Positive signal transmission line
2
TD-
Negative signal transmission line
3
RD+
Positive signal receiving line
4

Table 26: RJ45 connector on the Data Logger Board
The Data Logger board can be connected via the Ethernet interface to an Ethernet control device with
Modbus/TCP Master (PC) protocol in one of the following ways:
•
through a LAN network (company or plant Ethernet network)
•
with direct point-to-point connection
The connection via a LAN network can be carried out in the same way as for a PC. Use a standard
connection cable to the Switch or Hub or a Straight-Through TIA/EIA.568-B cat. 5UTP cable (LAN patch
cable).
NOTE
The interface board cannot be connected to old LAN networks made using Thin Ethernet coaxial
cables (10base2). Connection to this type of network is only possible using a Hub with both Thin
Ethernet (10base2) and 100Base-TX o 10Base-T connectors. The LAN uses a star topology with
each member element connected to the Hub or Switch by its own cable.
