Ethernet Interface (PLS62T-W LAN)
The Ethernet interface is implemented as 10/100 Base-T RJ45 Ethernet according to the IEEE
802.3 Ethernet standards, including PoE+ (IEEE 802.3at, backward compatible to IEEE
802.3af). For further characteristics see also
Appendix B: Ethernet Setup and Usage
for details on how to setup and use the
Java Terminal with Ethernet interface.

for the fast mode a rise
time of max. 300ns is per-
mitted. There is also a
maximum V

=0.4V at
3mA specified.
The value of the pull-up
depends on the capactive

maximum sink current of
I2CDAT and I2CCLK is
4mA.
If unused keep lines
