When attaching the module to the
T-type DIN rail, angle the top of the
unit towards the rail and locate the
top groove of the adapter over the
upper lip of the rail. Firmly push the
unit towards the rail until it snaps into
place. To remove, first separate the
input terminal block(s) from the
bottom side of the module to create a
clearance to the DIN mounting area.
Next, while holding the module in
place from above, insert a
screwdriver into the lower arm of the
DIN rail connector and use it as a
lever to force the connector down
until the unit disengages from the rail
(do not twist the screwdriver to avoid
damaging plastic).
The Ethernet port of this module is wired MDI and does not include
automatic crossover. The Ethernet port of your PC is also wired MDI and
may not include automatic crossover. As such, you must use a crossover
cable like that shown below when connecting this device directly to a PC.

Network
For 100Base-TX systems, use
data grade Unshielded
Twisted-Pair (UTP) wiring that
has a 100
Ω
characteristic
impedance and meets the
EIA/TIA Category Five wire
specifications.
It is recommended that you
use a crossover CAT-5 cable
to connect this device to your
PC.
For 10Base-T systems, you
may use Category 3, Category
4, or Category 5 UTP cable.
In either case, you are limited
to 100 meters between any
two devices.
A crossover cable simply
connects the differential
transmit pair on each end, to
the receive pair on the
opposite end.
Use a standard (direct) cable
when connecting to a hub or
switch port, which are
generally wired MDI-X.
