Connections, operating elements and LEDs
Subject to errors and modifications:
3.2 Ethernet connection
The Web-IO models provide an IEEE 802.3-compatible network
connection via a shielded RJ45 connector. The pinouts correspond
to an MDI interface, so that the connection to the hub or switch
can be made with a 1:1 shielded patch cable.
1 = Tx+
2 = Tx-
3 = Rx+
4 = nc 5 = nc
6 = Rx-
7 = nc
8 = nc
RJ45-Buchse (Belegung AT&T256)
10/100BaseT, Autosensing
Both 10BaseT and 100BaseTx standard with a bit rate of
100MBit/s and the possibility of full-duplex transmission are
supported. Changing between the two network speeds is
automatically done by the autosensing function of the Web-IO
depending on the possibilities of the hub or switch used. The
prerequisite for operation at 100MBit/s is suitable cabling (at
least conforming to Cat. 5/ISO Class D).
Galvanic isolation
The network connection is galvanically isolated with respect to the
supply voltage and to the digital IOs and the serial port(s) up to at
least 500V
rms
.
Link status
The Error LED on the front of the unit indicates the current link
status: If it flashes at 1-2 second intervals, there is no
connection to the hub or the connection is faulty.
